Nottingham subcontractor’s highly productive VMCs will give any competitor a run for their money, from Budapest to Beijing

A seminal moment has arrived in British manufacturing, it appears. Using the latest ultra-high-speed machine tools, UK subcontractors can rival their competitors in low-wage countries and still make a profit. Paul Cobb, managing director of Nottingham contract machinists, Hemlock Engineering, describes how this is possible using 30-taper Brother Speedio machines from Whitehouse Machine Tools.

He has calculated that the average 8-second chip-to-chip time on his 40-taper vertical machining centres (VMCs), of which he has 20, costs his company £400,000 per year in idle time for tool changes alone. The 1.4-second chip-to-chip time of the Brother Speedios would save Hemlock nearly a third of a million pounds annually if he operated 20 of them.

The received wisdom in UK manufacturing is that lower volume, higher complexity work has tended to stay on these shores while higher volume production of simpler components has largely disappeared abroad, notably to the Far East and more recently to former Eastern bloc countries.

Mr Cobb said, “Half of the parts we make are exported and most of the remainder end up abroad via our UK customers. OEMs are global and can have their components made anywhere in the world.

“Two or three of our contracts for annual quantities of 10,000 or more are under attack every year on internet auctions from competitors outside Europe.

“OEMs are always looking for lower prices. Subcontractors in the UK and presumably other Western European countries as well often do not get an opportunity to pitch, as their rates are expected to be too high.

“It is true that we would lose money doing this type of work using our 40-taper machining centres, even at the lowest hourly rate feasible.

“However, Brother Speedios are so incredibly fast that they give us an edge. They typically halve production times, knocking one-quarter off the cost of manufacturing a part.”

He also explained that, with a 4th axis indexer fitted, one operation can frequently be saved compared with using a 3-axis machine, which can reduce floor-to-floor time further, by up to a factor of three overall, cutting costs even more.

Instead of being 10 or 15 per cent too expensive, Hemlock can be a similar margin under the competition when quoting, or even more, so can realistically take on high-volume work and still make a profit.

Production rates two to three times higher

Mr Cobb is optimistic about the possibility of winning such contracts. He cites the initial job put on his first Brother Speedio S500X1 4-axis machine, which is equipped with a Kitagawa high-speed CNC indexer.

Whitehouse Machine Tools had demonstrated a turnkey manufacturing solution on the machine at its Kenilworth technical centre to show that the Japanese-built machines are a viable route to high profitability. The application involved producing a pair of left- and right-hand plates for a printer, 380 mm square by 12 mm thick, from solid aluminium.

For many years, Hemlock had been machining the plates two pairs at a time in two operations per plate on a 3-axis, 40-taper VMC in a cycle time of just over 48 minutes, or 24 minutes for two components. This included five minutes to refixture them all to drill holes in two opposing sides of each plate. Manual deburring of sharp edges took extra time, so in practice only four plates per hour were produced.

On the 4-axis, 30-taper S500X1, which has a working volume of 500 x 400 x 300 mm, a single pair of plates is machined in one hit over twice as quickly, in a 12-minute cycle. It includes deburring with a milling cutter, so the parts are ready for delivery immediately they leave the machine. The production rate is therefore 10 plates per hour, ie 2.5 times higher.

If the through-spindle coolant option on the Speedio had been chosen, the cycle time would have been even faster at just 8 minutes, equating to 15 plates per hour, or nearly four times the original production rate.

The productivity hike from the first machine, installed in August 2014, was so great that Mr Cobb decided to replace three additional 40-taper machines straight away with Brother Speedios. Two further identical models were installed, as well as an S700X1 with 700 mm travel in the X-axis. All four were delivered within the space of one month. The larger machine is fitted with through-spindle coolant and a faster Yukiwa CNC indexer, which rotates at 200 rpm, double the speed of the Kitagawa indexers.

Mr Cobb continued, “All of the indexers fitted by Whitehouse are not only fast but also very rigid during machining. It is because they are clamped hydraulically at both ends, rather than being held by the servo motor.

“It allows us to take heavy milling cuts without vibration, maximising productivity and prolonging the life of the cutters.

“In addition, their speed of rotation enables us to spin swarf off the components and fixtures after each cycle, so we save a few more seconds by not having to blow the chips away with an air gun.”

Fast when cutting – and between cuts

Rather than having a standard 10,000 rpm spindle or the 27,000 rpm option, all of Hemlock’s Speedio VMCs are fitted with a 7.4 kW / 16,000 rpm spindle. Mr Cobb considers it optimal for machining the various grades of aluminium that account for around 95 per cent of production at the Nottingham factory. He believes that higher speed spindles lack torque and require unnecessarily costly, balanced tooling, while lower speeds are not enough for productive removal of light alloy.

Rapid spindle deceleration to zero for tool exchange and acceleration to full rpm as well as quick indexing of the 21-station turret combine to bring the chip-to-chip time down to 1.4 seconds, cutting out a lot of idle time. Tapping at 6,000 rpm also promotes high productivity, as do 50 m/min rapids in the linear axes, up to 30 m/min cutting feed rate and axis accelerations of up to 2.2g.

A comparative analysis of the cutting data from the standard VMCs and the new Speedios at Hemlock reveals that, on average, the former are in-cut for 45 per cent of a cycle whereas the Brother machines are cutting for 66 per cent of the time. It results in a massive potential increase in metal removal of nearly 50 per cent.

Another facet of the machines that Mr Cobb appreciates is the power of the latest Brother CNC system. It has faster processing and 200-block look-ahead, enabling higher accuracy machining, especially in 3D. It also has many standard features that are costly extras on other controls. He pointed to the Brother CNC C00 specification at the URL: www.brother.com/europe/machine/sx1/spec/index.htm#spec-nc

and noted that 58 features are standard in the proprietary control and only five are options.

Two more Speedios every year

In conclusion, Mr Cobb said, “Our new Speedios will give any of our competitors a run for their money, whether they are in Budapest, Beijing or anywhere else in the world.

“We plan to replace two of our standard 40-taper VMCs with two Speedios every year for the foreseeable future in a bid to halve production times right across our shop floor.

“We have around 2,000 job numbers here. It takes time to swap jobs from our existing machines to the new platform because we rewrite each program, rather than just edit and transfer it. Only in that way do we gain maximum productivity advantage from the Speedios and Whitehouse helps with that.”

Most cycles, invariably involving interpolation in up to three axes plus indexer positioning, are created off-line using seats of hyperMILL and Mastercam. Occasional data input is required on the shop floor for programming simple jobs or to edit cycles.

Further advantages of the new Brother machines are their low power consumption, which reduces electricity bills, and their superior accuracy, with 10 microns positional tolerance routinely held by Hemlock.

The proximity of Whitehouse Machine Tools’ HQ has also been a benefit. The Brother agent’s applications engineers frequently visit the Nottingham subcontractor to assist with setting up jobs and to give advice.

Using the Right CNC Machine Tools for Your Business

When Computer Numerical Control or CNC was invented, it was a technologically adapted concept to make impossible and intricate designs possible. By means of a special program, CNC machines can be used to control any tool to cut, form and shape metals with absolute precision, in next to no time.

Today, CNC machining has benefited businesses in producing complex shapes, like 3D designs that are impossible to achieve with manual machining. There are many kinds of CNC machines used in different industries, ranging from drilling machines to plasma cutters. However, choosing the right CNC machine tool for your business depends mostly on your needs. So what are the different CNC machine tools you can ustilise for your business?

Turning centres – also known as lathe machines. Usually, lathes are used to produce parts that are cylindrical in shape. Turning centres still have two types: vertical turning lathe machines and horizontal turning lathe machines. The difference between the two lies on the axis of their spindles. Horizontal turning lathes are better used for boring and producing round pieces, whereas vertical turning lathes are preferred for milling, face work and designing large and heavy work-pieces. Of the two types, horizontal turning lathes are more commonly used.

Turn mill centres – are like two machines in one, enabling both milling and turning functions. Due to this characteristic, turn mill centres are mainly used for multiple operations and are a cost-effective option, cutting down setup and operation time.

Grinding machines – are similar to lathe machines. However, instead of being a cutting tool, grinding machines have a grinding wheel for grinding metal, polishing metal and smoothing metal surface finishes.

5-Axis machines – are efficient CNC machines because their five axes are able to move in different directions, simultaneously. These machines are also ideal for fewer errors and they reduce time setup of complex parts and afford quicker production.

On the other hand, there are also machines that can be custom-built for specific CNC operations. These machines include:

CNC routers – are mainly used for cutting wood, plastics and sheet metals with complex shapes or those used in prototype models.

CNC plasma cutters – are like CNC routers in setup and size but are only used for cutting 2D profile shapes into sheet metal using a plasma torch.

CNC laser cutters – use the same principle that CNC plasma cutters use. Unlike their plasma counterparts, laser cutters are less destructive and are an ideal option for cutting wood, plastic and metal. Different laser strengths are used in line with the type of material to be cut.

3D printers – are perhaps the most popular type of CNC machines that even laymen are familiar with. These printers are similar in set up to CNC routers and CNC laser cutters, except that they utilise a plastic extruder. The latter is used to push out hot plastic through a tiny hole, as layer by layer, a 3D model is produced.

CNC Machines in Different Industries

CNC machining is perhaps one of the most commonly used processes in theUK’s manufacturing industry. With the help of technology – computers and special codes, CNC milling machines are able to produce small and intricate parts with more precision and efficiency, compared to manual machining.

CNC Machines and Different Industries

There’s no doubt as to why CNC machines are used in almost every aspect of manufacturing – they provide improved and enhanced precision.

CNC machining make intricate designs, which may be impossible to manufacture with manual machining, possible. While the application of CNC milling machines can be numerous, here are some industries thatuse different types of CNC machines.

Metal Removal Industry

-        CNC machining centres include all types of milling processes; face milling, slot milling, contour milling, counter boring, tapping, boring, reaming and drilling.

-        CNC turning centres include all types of turning operations involved with boring, turning, threading, grooving, knurling, and facing.

-        CNC grinders are usually used for internal diameter and outside diameter grinding. Unlike before, CNC grinders can now be used for contour grinding which is very similar to turning.

-        CNC milling machines, CNC lathes and CNC drill and tapcentres are other types of special machines utilised for metal removal.

Metal Fabrication Industry

Fabrication usually refers to thin plates of metal in terms of manufacturing. Fabrication typically entails the process of shearing metal plates to size, punching holes and bending the metal sheets to form their final shapes. Aside from this, fabrication may also include operations like welding, plasma cutting and forming.

-        CNC lasers and CNC plasma cutters can be used to form and cut metal plates.

-        CNC turret punch presses can hold various punch-and-die combinations to easily punch holes of all shapes and sizes

-        CNC press brakes allow metal plates to be bent into their finishing shapes.

Electrical Discharge Machining Industry

Electrical discharge machining (EDM) is the process of removing metals by burning them away through electrical sparks. CNC EDM has two types: vertical EDM and wire EDM.

-        Vertical EDMcommonly uses a CNC machiningcentre and requires an electrode shaped according to the cavity to be machined to the work piece. Think about a mould used for shaping.

-        Wire EDM on the other hand is used to make punch-and-die combinations for die sets.

Other uses of CNC machines

Some more popular uses of CNC machines involve making components for the electrical industry. Soldering irons, CNC coil winders and CNC terminal locations are several of these electrical components made by CNC technology.

Engraving systems also use CNC technology. This is done with waterjet machining which cuts through metal plates using high pressure jet streams of water.

About CNC Machining

CNC machining allows anyone with the right knowledge and skills to manufacture virtually any object, through the use of computers and advanced programs that control highly precise machining tools.They see heavy use in the manufacturing sector,thanks to their accuracy, speed and efficiency compared to human effort.

Benefits of CNC machining

  • Fast –After an object has been designed, it can be created by the machine without the delays caused by slower human movement.
  • Durable – CNC machines are built to last; only requiring maintenance every now and then.
  • Precise –No matter how small or large the object, CNC machines can fabricate it with minimal errors or mistakes. Thanks to their precision, some objects are only possible because of CNC machines.
  • Versatile–Several tools can be connected to CNCs, allowing the machine to control them. They can also perform a variety of machining techniques.

How CNC machining works

The main component in CNC machining is the CNC or Computer Numerical Control, which is composed of a computer and a specialised CNC program. Together, they’re the brains behind the whole outfit but it still requires a skilled CNC machinist, someonewho is familiar with the software and the machine tools attached to the CNC.

To illustrate the difficulty of CNC machining, the machinist has to use the software to create precise designs of their project andadjust settings for the tools such as speed, feed rate and location.Afterwards, they have to create a prototype to check for errors or defects.In exchange for the added complexity, CNC machines can produce components rapidly and accurately, without any human input if the prototype has passed quality control.

What kind of machining tools can be attached to the CNC?

Many machining tools have been adaptedto be compatible with CNC software; here are some examples of these tools:

  • Routers
  • Grinders
  • Mills
  • Drill press
  • Lathe
  • Screw machine
  • Milling machine
  • And more

Compared to manual procedures, many CNC machine toolsalso combine turning, milling and grinding capabilities into just one machine.

Choose the 3D Scanner That’s Right for You

The introduction of 3D scanners has greatly improved the technology of various industries so much, that today theyare considered indispensable. This is most true, especially in the machining industry, where the data gathered by 3D scanners becomes very useful in terms of making prototypes.

These devices have also become great instruments when it comes to conducting highly advanced studies and research in many other sectors.

The technology behind every 3D scanner

A 3D scanner is a type of device that is used to collect data, by analysing an object’s properties and outer appearance.  The great advantage of these top of the line scanners is that the data they collect can be utilised to create models or replicas which are three dimensional.

3D scanners can be built through different technologies, depending on the desired purpose and function but these technologies also set the limitations for each device.

How relevant is a 3D scanner?

There is a wide variety of 3D scanners available on the market today but among the top industries that commonly make use of them, are the ones that involve programming and machining.

3D scanning plays an important role, as it serves as the perfect tool to capture the almost exact image of any object in a digitalised format, which later on serves as a blueprint for a particular project.

Over the years, there have been many kinds of 3D scanners that have been made to better suit the needs of everyone. With all the options out there, how can one know which to get? Here are some considerations that might prove to be helpful.

Purchasing a 3D scanner

Personal use Vs. Commercial use

If you are planning to buy a scanner, first determine whether it’s for personal use or for business purposes. Knowing exactly where you would use it has a great impact in choosing the scanner that would best suit your needs.

Is it portable?

Some laser scanners are easy to carry around – that is if you’re scanning small objects. What if you need to collect data from an enormous object? What if the thing that you need to scan is something that can’t be moved at all? If you keep these considerations in mind, you can surely save yourself a lot of inconvenience at a later stage.

Is it precise?

It’s easy to realise that the more accurate a scanner, the more expensive it is likely to be. A 3D scanner with excellent quality also comes with a hefty price tag. Think about your needs and decide on how this resolution factor would affect your task.

Buying a 3D scanner might seem easy but without conducting some thorough research, you might end up being confused with all the options. The most effective way to make your choice is to first determine your purpose and to know exactly the specifications that you need.

MITUTOYO CMM AT HEMLOCK ENGINEERING

CNC milling dictates precision and it is imperative to achieve perfection. In order for CNC engineers to meet the perfection that they want, a CMM or Coordinate Measuring Machine is needed.

WHAT IS A COORDINATE MEASURING MACHINE?

A CMM or Coordinate Measuring Machine is a machine that measures the physical geometrical characteristics of an object. It can be controlled by an operator or alternatively, if the machine is more advanced, a computer can control its movements.

A CMM is comprised of three main components: the machine itself, the measuring probe and the controller. As previously mentioned, the controller can be a person or a computer equipped with the right measuring software. These three components are designed to measure the following:

  1. Dimensions – the measure of combined width, height and length of an object. Dimensions are made of unique independent coordinates that are required to specify points in a space.

  2. Profile – an outline or a representation of an object that can be seen from the side.

  3. Angularity – the measurement of angles, most especially of outlines or corners of an object.

  4. Depth – the downward dimension measurement of an object to measure its range.

  5. Digitising – the process of putting the collated data into digital form.

  6. Shaft Measurements – the measurement that involves the capital and base of an object.

A CMM is definitely a must-have to move a measuring probe. It helps to determine the coordinates of points.

At Hemlock, we strive to deliver the best quality work to our clients. This means that it is imperative for us to choose only the best equipment to generate the best output. Our choice is the expertise of the Mitutoyo CMM. The Mitutoyo CMM is the worldwide leader in the development of output gages, data collectors and analysis software. Furthermore, the one-of-a-kind technological advancement of Mitutoyo paves the way for us to push measuring accuracies into the micro-meter range.

A Mitutoyo CMM is designed using the latest CAD techniques and we are proud to incorporate this milling giant into our day to day production at Hemlock. The latest CAD techniques that complement a Mitutoyo CMM will surely produce an output that is not only of unfaltering quality, but is also made from the best materials. The unparalleled technological expertise of the leader in metrology enables the combined skills of both Mitutoyo and Hemlock to produce any CNC milled output in a timely manner, which is essential in this naturally fast-paced industry.

CNC Machining at Hemlock Engineering Ltd

CNC Machining is defined as a process that is used in the industry of manufacturing. It involves the use of computers and special codes in order to control specific machine tools that are used to create small, intricate parts. These are later utilised in various sectors. Some examples of the tools that can be manipulated through this technology include the following:

  • Lathes

  • Routers

  • Grinders

  • Mills

CNC Machining makes use of unique computer software that allows it to operate most efficiently, without the problem of having below standard output. Machine tools under CNC machining function through a set of numerical codes also known as G code. These numerical codes are carefully programmed per machine to perform a specific action and to produce a desired product.

Advantages of CNC Machining

  • CNC machining is a more precise process compared to manual machining.

  • It has the ability to repeat an action again and again, over a longer period of time, without any change in the product or output.

  • It can mass produce small, intricate shapes that are usually difficult or impossible to achieve using manual machining.

  • Before CNC machining, the quality of the output usually depended on the skills of the machinist. Thanks to CNC machining, production of industrial products is mostly capable of operating with less supervision.

Machining at Hemlock Engineering Ltd

  • CNC Turning – At Hemlock Engineering Ltd, we are proud of our very own fixed head turning cell. Through this cell, we are able to machine parts that are up to 12 inches in diameter. Nakamura WT150 and 4 Doosan CNC lathes comprise this fixed head turning cell.

  • CNC Milling – We own over 20 Haas VF2-SS Vertical CNC machines. These machines come with 4th axis trunions and Kurt double lock vices that allow the completion of side features in a single hit.

  • 5 Axis CNC Milling – At Hemlock, we are able to surface aluminium at 36000 rpm through our 5 axis Mikron machines. They also have a speed of up to 90m per minute. These Mikron machines are considered as one of the fastest machines all over the world, especially when it comes to High Speed Machining.

  • Sliding Head Turning – Our sliding head capacity is offered through our sister company, HPC Services, Ltd.

CNC Machining in the UK has greatly improved over the years. At Hemlock Engineering Ltd, our goal is to continuously produce the components that our clients require, as accurately as possible, with the help of our machines. In the past years, more and more powerful machines have been introduced in the market and they have proved to be a great contribution in the development of the manufacturing industry today.

LOW COST OF OWNERSHIP DISTINGUISHES HERMLE 5-AXIS MACHINING CENTRE

A third 5-axis, vertical-spindle machining centre (VMC) has been installed by subcontractor Hemlock Engineering, Nottingham, in response to a steady increase in work from a variety of sources. Aircraft seat parts, medical prostheses, components for laser equipment used in dentistry and printing, fire suppression nozzles and parts for camera tripods and beer pumps are typical of the diverse range of contracts regularly received from more than 200 customers.

A long-time user of over twenty 3-axis and 4-axis VMCs, the company later invested in two 5-axis machines with 36,000 rpm spindles and 90 m/min rapids for high-speed finishing. In contrast, the latest Hermle C 22 U, supplied through UK agent Geo Kingsbury, is a more robust 5-axis model capable of highly productive metal removal.

Even though 95 per cent of jobs undertaken by Hemlock are in aluminium, high power and torque are still needed when taking deep cuts to prevent the cutter stalling. The Hermle’s 25 kW / 80 Nm / 20,000 rpm spindle, 45 m/min rapids and 450 x 600 x 330 mm working envelope are ideal for the subcontractor’s needs.

Two factors distinguish the C 22 U, in the view of Hemlock’s managing director, Paul Cobb. First is the machine’s reliability, as it has operated faultlessly since it was installed in March 2013. Second is its ability to hold extremely high tolerances, down to a few microns on some optical parts used in dental laser equipment.

Mr Cobb commented, “There were less expensive machines on the market than the Hermle, but it was by no means the costliest. We also prefer the Heidenhain control option, rather than the Fanuc CNC system which comes as standard on many other machines.

“The price of a machine tool is of secondary importance, particularly at the moment with interest rates as low as they are. It is uptime that is crucial in order to maintain output and profitability, and also the cost of repairs, which tends to be high when a 5-axis machine goes down.

“Repair bills have been a problem with some of the machines we have installed over the years, but the C 22 U has performed well. It has not missed a beat working 20 hours a day for the nine months that we have owned it.

“I thought it was going to be a good machine when I saw them being made at the German factory and it has not disappointed. The build quality is awesome and the clever design ensures that vibration is minimised, resulting in lower tooling costs, higher accuracy and less wear and tear on the machine.

“I know it will still be good in 10 years and more, so now I could not imagine buying any other make of 5-axis machine.”

It is rare for the Hermle C 22 U at Hemlock to be used in full 5-axis mode. Most jobs require one or two operations involving 3-axis machining with the two rotary axes fixed. Cycles are created off-line using seats of hyperMILL and Mastercam.

Typical of components produced are aluminium blocks that direct a laser beam through a multi-axis articulating arm used for hardening dental fillings. A couple of microns has to be held to achieve the required angular tolerance either side of 45 degrees, which is only possible in a shop floor environment by machining it on three sides in one set-up on the C 22 U. Brackets for military night vision goggles are another example of tightly toleranced parts produced on the machine, requiring ±10 microns to be held.

Production of large aluminium heat sinks for electronic equipment is a regular job to be found on the machine. Their dimensions preclude extrusion and castings do not have the correct thermal diffusion characteristics, so they have to be machined from solid. Deep, closely spaced fins complicate their manufacture, but again the combination of high metal removal rate on the Hermle using small cutters at 20,000 rpm together with rotary axis positioning allows the parts to be produced in two hits in much faster cycle times than previously.

Hemlock Engineering has a sister company, HPC services, specialising in sliding-head turn-milling from up to 32 mm bar and fixed-head turning to 65 mm diameter. The group was established in 1986, employs 70 people, has a turnover of £7 million and in addition to production runs, regularly undertakes prototyping and sub assembly.

Precision is Perfection

CNC Milling or Computer Numerical Control is the process used by engineers, where CAD software is used to draw specific templates and CNC machines are implemented to produce precise and detailed designs. Through this innovation, the demand of certain establishments to mass produce highly precision materials can be made possible. In order to produce hundreds of pieces that are totally alike, you just need to set up the CAD drawing in the machine. You can do this without forsaking the quality of the materials.

For certain industries like transportation, CNC milling is very advantageous because special gears that need particular polishing will be completed with high precision, without diminishing the quality; because if not crafted accurately, these parts will create a huge problem when it comes to safety. Furthermore, strength should also be evaluated because the intricate details of the parts will make a huge impact to the performance of the vehicle. Creating a highly detailed piece will be costly because of its design but since mass production can be easily accomplished through CNC, the high volume production of the precise materials can be affordable.

However, establishments should still be careful before deciding to order a mass produced specific part for their business — this is why prototyping is done before mass production.

WHAT IS PROTOTYPING?

A prototype serves as the model or the “first production” of the output that is used to test the concept or the process exercised to make the product. This material will be replicated or learned from.

WHY IS PROTOTYPING IMPORTANT IN CNC MILLING?

More often than not, new designs have unexpected problems. Through prototyping, the design will be evaluated and queries regarding any issues will be answered. For instance, a prototype is used to answer the question of whether the new design has actually improved and met its purpose.

Furthermore, a prototype is also used by engineers to explore options for design alternatives, test theories and to confirm performance prior to the mass production of the product. The first product also gives the company the option to study the design to determine whether it will be accepted by their consumers or not.

Most importantly, prototyping saves companies a lot of money. Any changes in the design are better done during the early stages of production. A change that is implemented after mass production itself will be more costly than correcting what is inaccurate at the first few stages of the production.

CONCLUSION

Prototyping is critical as it is the driving force behind knowing the feasibility of the design — you can never formulate a conclusion before having a prototype. A prototype gives you a hint of whether your ideas have prospered or failed — furthermore, it can give you the option to take a first glance of your product before it moves to the full development stage. This will afford the chance to change your ideas and approach to result in a more pleasing output.

The Road to Hyperinflation

If you look – the signs are all around you.

Something that has happened many times before but never on a global scale .

Its going to happen at some point and its almost a mathematical certainty

Stock markets around the world are booming and yet the that has nothing to do with the economic fundamentals.  The reality is that the economies have massive debt and increasing deficits so why would they hit all time highs?

Throughout history this has shown to be a possible sign of imminent hyperinflation. Its called the Crack up boom (coined by the famous austrian economist Ludwig von Mises). People borrow money and buy anything because they know the money they owe will worth less than it is now at some point in the future. Zimbabwe had a stock market that doubled every few weeks (when measured in zimbabwe dollars) and it looks to me as though Japan is going to go first with the rest of the world to follow.
Japanese debt is enormous and is accelerating. The Japanese bond market is collapsing and soon the bonds will be totally worthless.

However all is not lost. Gold and Silver are down  – possibly as people have rushed to the dollar to get away from the collapsing yen and some manipulation in the paper market by the bullion banks. You have one last chance to buy some at a decent price and take delivery of it. The next move is up …….to infinity and beyond!  Go get some now before its too late.
