Development Of Precision Machining And Metal Machining Within Malaysia

By Jason Nyback


Precision machining is the process of removing material to a very high tolerance from a component. The material of the machine and other factors determine the tolerance held. However, most precision machines from Malaysia do not really have a problem in holding 0.002 to 0.005 mm of tolerance. There are numerous classifications of precision machining including Milling, turning, Jig Boring, laser cutters, water cutters and metal machining products.

Precision machining is used for everyday items like clocks, electronic motors, engines of automobiles and such regular items of day by day use. Countries like Germany and Switzerland are well reputed in maintaining a high standard of engineers related to the technology of metal machining and Malaysia is doing the perfect job among these leading countries as well. Other countries that are developing this technology are Japan and England.

Metal machining products are custom made according to the requirements of the client. They reflect the tolerance features necessary from the critical parts of engineering. The alloy of tungsten has nickel, copper and iron and also has the high density of pure tungsten. Pure tungsten is understood for its high melting point and density.

Molybdenum is another very common metal used in precision machining. Molybdenum again has a high melting point of 2620 degree Celsius. At temperatures above one thousand degree Celsius, it may retain the tensile strength. It is a good conductor of electricity and is an efficient materials for electronic, lighting and semiconductor industries. It also has a low coefficient of thermal expansion.

Precision machining uses cutters and tungsten carbide could make solid cutters, cobalt and even HSS. In Malaysia, they manufacture their very own cutters and that brings down their total effective cost price. In addition they use water cutters which use water under extremely high pressure conditions but are very accurate.

Metal machining additionally makes use of laser beam cutters to be able to erode the surface of the metal. However, this process could be very expensive and therefore doesn't find much use in the industry. Malaysia is the one the USA that has recently started making its own parts of the laser beam method as well. Therefore, this convenient process has started being used in the precision machining industries in Malaysia.

Drilling machines, boring machines involved in the process of metal machining are all produced in large quantities in Malaysia. They are even exported for increased benefit to their economy. For the machining of brittle materials like ceramic, ultrasonic machining is required to gently remove smaller particles. These ultrasonic units are also manufactured in Malaysia.

Precision machining instruments are classified into totally different categories in response to the precision exhibited by the machines. Tools of increased precision are classified under class 'P', these of high precision under class 'H', those with super high precision under class 'A' and the very best precision under class 'S'. The metal machining industry in Malaysia doesn't use the class 'P' tools to be able to maintain good quality of the products.

Malaysia is attempting to develop precision machining tools with numeric control with self-adjusting control facilities. Other trends include increased durability and longer operating life.
