The automotive industry is one of the industries that rely heavily on precision manufacturing technology due to the level of precision and accuracy their operations require.

For a better understanding of what precision manufacturing is all about, let us first look into what precision machining is all about.

What is Precision Machining?

Precision machining is a sort of high-tech engineering that is needed for the creation and design of mechanical parts needed in space-age productions. This process results in the production of devices of various sizes that is essential in our day to day living.

Precision machining is used to assemble devices made of numerous small parts to ensure that they fit and function optimally.

Simply put, precision machining means pushing the limits of a device, a program, or a tool in order to reach its peak of performance. However, to ensure safety, a device must not be pushed beyond specified tolerance during precision machining.

When it comes to precision machining, the real art is in being able to reconcile man-made designs and computer-controlled processes for the manufacture of exclusive features. With precision machining, engineers can manufacture tools that are detailed and resilient consistently and accurately.

Benefits of Precision Machining

Precision machining is a reductive process. It is used anytime a certain substance has to be subtracted from a raw material before the finished product can be gotten.

This process is necessary for the production of different devices and parts for a large number of materials and objects. Production of such a piece normally requires precision and accuracy. There isn’t much room for flaws and mistakes.

Tolerance and consistency are the main attributes of precision machining. Every single piece is built to maintain a very high level of tolerance. For instance, if two or more parts of a machine are required to work hand in hand for the proper functioning of the machine, both parts must orient within a margin of 0.01mm to 0.05mm.

Precision machining ensures that not only are machine parts built with accuracy, but they can be replicated exactly over and over again. This process is also used for the repair and restoration of worn-out tools or parts.

Modus Operandi of Precision Machining

Precision machining uses custom programmings, tools, and raw materials like metals, rubber, and ceramic for the manufacture of various desired products. For this manufacture to take place, step by step instructions has to be given by computer-aided manufacturing (CAM) programs and computer-aided design (CAD).

These instructions further increase the ability of a part to meet narrow tolerances. Some designs are hand-drawn in the initial stage before they end up as computer-aided designs.

Tools and Materials Needed for Precision Machining

Some tools used for precision machining include:

  • steel
  • ceramic
  • glass
  • composite
  • plastic
  • metal
  • graphite
  • Electric Discharging Machine
  • saws
  • milling machines
  • grinders

The most common equipment used is heavy machinery controlled by computers which are normally used to get rid of unwanted underlayers.

Conclusion

Precision machining is an art that remains new every day. It is a very important process especially for high-tech industries where precision and accuracy is a key factor.
