What Is CNC Precision Machining

CNC precision machining refers to processing with an accuracy of 10-0.1 um and a surface roughness of less than 0.1 Ra. It is always called precision machining or precision parts machining.

What are the commonly used machining methods for precision machining?

Commonly used processing methods include diamond turning, diamond boring, honing, grinding, super finishing, abrasive belt grinding mirror grinding, etc.


What are the applications of precision machining parts?

Precision machining plays a very important role in the manufacturing industry and is often used to machine key parts such as precision screws, precision gears, precision turbines, precision guide rails, and precision bearings.


What are the differences between precision machining and non-traditional machining?

1. Targeted parts are different

Non-traditional machining is usually used for parts of special materials or shapes and requires special processing methods.

Precision machining pays more attention to the surface quality and dimensional accuracy of the custom parts, without any restrictions on shape and material.

2. Technical requirements are different

Non-traditional machining requires highly precise machines and technologies, such as electrical discharge machining and electrochemical machining.

Precision machining requires operators with skilled cutting and grinding techniques.

3. Processing methods are different

Non-traditional machining uses special process methods, such as high temperature, high pressure, or electric discharge machining processes, etc. It does not use formed tools but uses energy beams for processing.

Precision machining mainly uses a cutting or grinding process to gradually improve the dimensional accuracy and surface quality of the custom part.

CNC Precision Machining provides precision machining of complex custom parts and reduces production costs at the same time. As a highly developed and reliable technology, precision CNC machining reduces human participation and interference in the manufacturing process to ensure and improve parts accuracy and efficiency.
