MACHINE TOOLS
A machine tool is typically powered by electrically, hydraulically, or via line shaft and is used to make manufactured components by cutting or grinding on metal. There are approximately 600 machine tool brands and 7500 new models to choose from. Not surprisingly, the new machine tools industry confronted its toughest challenge during the financial world economic recession and orders for machine tools declined. Reduced engineering activities resulted in less demand for machine tools.

Europe and Asia-Pacific have the lion’s share of the global new machine tools market and this could grow by 6.6% in the future.  There has to be a significant increase in demand because of the now aging machine tool bases which need upgrading.  As a result of this, used machine tools are available from many companies throughout South Africa.  They supply machine tools such as CNC Machines, Metal working Machines, Injection Moulders, CNC Plasma cutting machines.  They usually employ full time technicians that are factory trained to repair, install and commission these different machines.  In addition some companies offer In House Training Centres for CNC Programming courses.

hese are some of the new machine tools being manufactured worldwide: Metal Cutting Tools (Boring & Drilling Machines); Gear Cutting Machines; Grinding, Honing, Lapping, Polishing, and Buffing Machines; Lathes; Milling Machines; Machining Centers; Station Type Machines; Metal Forming Tools (Punching & Shearing Machines); Bending & Forming Machines; Metal Working Presses; and Miscellaneous Tools, and Special Machine Tools (Water Jet Machines; Laser Machines; Electro Chemical Machines; Electrical Discharge Machines; and Coordinate Measuring Machines).

Gold Coins  What You Need to Know

       Gold sparks brilliance. Gold is wealth. Gold is growth and development. Gold evokes Christmas celebration. The list goes on and endlessly.

When a person or an anniversary reaches 50, it is famously known as the golden year and a fabulous merriment caps it. One word to say it all is EXTRAORDINARY. That is the real meaning of gold. It is something that everyone is looking forward to. It is a coveted object.  It could even trace its beginning within a great historical sphere.

So, how does gold fare when these are made into coins?  When it comes to coins, it calls to mind that these coins glitter, symbolize prosperity and celebrations and are desired by many. These gold-colored coins are the exact replica of the descriptions done in the first two paragraphs. To add to the list of description, these unique coins last forever and are indestructible.

Whether used as an investment or for collection purpose, the value of these shimmering coins depend a great deal on how rare it is (pre-1933 dated US coins), how old, how they look like, and the number of mintage used.

Selling and buying coins is a very exciting and adventurous event. The incomparable golden coins of the early times are shrouded with controversy and mystery on top of their multi- million dollar worth. Private collectors who usually dipped their fingers to own it never went public. Exposing themselves in auction or in private sale is a big no. They successfully and covertly sealed with finality those highly coveted and pricey golden coins anonymously.

A US exceptional coin was sold and bought at Sothebys, leaving behind a legacy in the market.  The brilliant year 2002 was a witness to an acquisition of a much desirable and famously known collectors item. The month of July recorded the sale of the most highly esteemed coin, the $ 20 Double Eagle gold coin that was produced and circulated in 1933. It was obtained in a staggering amount of $7,590,020. It is said to be the costliest payment made during an auction which lasted for only 9 minutes and the owner was an anonymous bidder which until now has not been disclosed. 

There are other 10 Double Eagles that are being kept at the United States Bullion Depository in Fort Knox, Kentucky since 2003 because of a resolved criminal case that was filed against an illicit  coin dealer  from Philadelphia whose possession of these rare coins were darkly questionable. How it was traced to him by the US Secret Service and how these scarcely prized coins were retrieved and returned to the US government as its property is just a peek on the degree and extent of how some people laid their hands on them to possess them and how the government went after these golden coins to protect its national treasures.

Other sales of exceptional coins were done outside the US. Noteworthy of these is the Canadian Gold Maple Leaf which is known as the bullion gold of Canada. This was produced by the Royal Canadian Mint. The coin was said to be one of the purest gold-based coins that was regularly issued in the world. It was only produced as a promotional product initially. But later, the Mint declared that it would produce more through orders because at an earlier time, there were interested buyers who signified their intentions directly to obtain them. In May 2007, there were 5 persons who confirmed their orders in which each paid between $ 2.5 and $3 million. There were coin dealers who complained about the quality of work done on the Canadian Gold Maple Leaf which is a standard problem with pure gold.

In October 2007, another rare coin was sold to an anonymous private collector to the tune of $5 million. This was a $10 eagle coin that was produced in 1804.

It is no longer puzzling as to why collectors and investors engaged in the golden coins business. And behind those rare coins are great stories that validate their excessive costs, why they become exceptionally acquired, how their ownership are cloaked with drama and mystery and show the length the US government participates in defending these national treasures.

BEARING PULLERS

BEARING PULLERS
In a general discussion on bearing pullers, the Posi Lock range of products has been designed with efficient
performance, enhanced safety, and reduced down time in mind. The bearing puller range has pulling capacities of up to 100 t. Another special feature of the lightweight and user-friendly range is a patented control cage that holds the pulling jaws securely in either open or closed positions – thus enabling effective removal of stubborn gears, bearings, pulleys, and other press items from any machine in diverse industries,” says Becker Engineering product manager Eugene Davids.

An advantage to be looked at when choosing a bearing puller is that it can be operated easily, safely, and
efficiently by one man and doesn’t require a team of workers to hold the jaws from snapping back.  The centre
bolt threads should provide less effort in applying high torque and  a cage could prevent the jaws of the puller
from falling off the work surface which would extend the life of the tool and worker safety.

There are two types of bearing pullers available:  manual and hydraulic with the appropriate adaptor sets and special tools and accessories. An innovation in this market is the internal bearing puller kit, which offers fast and easy bearing removal with an ergonomically designed sliding hammer and a selection of spring-operated extractors. These bearing pullers are specifically designed for removing a bearing from a housing where the bearing’s fit is on its outer ring.

WHAT ARE BEARINGS?

WHAT ARE BEARINGS






Bearings are a special device to allow relative motion between two or more parts – typically rotating or linear movements and may generally be classified according to the movements they allow. Thus, there are many types of bearings, with varying shape, material, lubrication, principle of operation, and so on


 






















Plain bearings


use surfaces in rubbing contact, often with a


lubricant such as oil or graphite.  


Rolling-element bearings


use spheres or drums rolling between the parts to reduce friction; reduced friction


Jewel bearings


in which the load is carried by rolling the axle slightly off-center


Magnetic bearings


In which the load is carried by a magnetic field


Fluid bearings


Which solely support the bearing’s load on a thin layer of liquid or gas


Thrust bearing


Is a particular type of rotary bering that permits rotation between parts


 


 


Common motions permitted by bearings are:


·                    Axial rotation e.g. shaft rotation


·                    Linear motion e.g. drawer


·                    spherical rotation e.g. ball and socket joint


·                    hinge motion e.g. door, elbow, knee


 


Reducing friction in bearings is important to reduce wear and to facilitate extended use at high speeds and also to avoid overheating. A bearing can


reduce friction by virtue of its shape, material component (plastics that have low surface friction) or by introducing a fluid or electromagnetic field between surfaces.


 


Speeds


Plain bearings only handle lower speeds, rolling element bearings are faster, followed by fluid bearings and finally magnetic bearings which are limited by centripetal force overcoming material strength.

Plain bearings use surfaces in rubbing contact, often with a lubricant such as oil or graphite. A plain bearing may or may not be a discrete device. It may be nothing more than the bearing surface of a hole with a shaft passing through it, or of a planar surface that bears another (in these cases, not a discrete device); or it may be a layer of bearing metal either fused to the substrate (semi-discrete) or in the form of a separable sleeve (discrete). With suitable lubrication, plain bearings often give entirely acceptable accuracy, life, and friction at minimal cost. Therefore, they are very widely used.


However, there are many applications where a more suitable bearing can improve efficiency, accuracy, service intervals, reliability, speed of operation, size, weight, and costs of purchasing and operating machinery.


Thus, there are many types of bearings, with varying shape, material, lubrication, principle of operation, and so on. For example, rolling-element bearings use spheres or drums rolling between the parts to reduce friction; reduced friction allows tighter tolerances and thus higher precision than a plain bearing, and reduced wear extends the time over which the machine stays accurate. Plain bearings are commonly made of varying types of metal or plastic depending on the load, how corrosive or dirty the environment is, and so on. In addition, bearing friction and life may be altered dramatically by the type and application of lubricants. For example, a lubricant may improve bearing friction and life, but for food processing a bearing may be lubricated by an inferior food-safe lubricant to avoid food contamination; in other situations a bearing may be run without lubricant because continuous lubrication is not feasible, and lubricants attract dirt that damages the bearings.
