CNC Precision Machining

CNC Precision Machining is a process of changing workpieces, mainly through the precise adjustment of the external dimensions or performance of the workpiece through machining machinery.
It includes two categories: cold working and hot working. Cold processing is usually carried out at room temperature without causing any chemical or phase changes to the workpiece; However, hot processing is carried out at temperatures above or below room temperature, which may cause chemical or phase changes in the workpiece.

Precision machining methods mainly include precision turning, precision boring, precision milling, precision grinding, and grinding processes. These methods are achieved using precision machine tools, precision measuring tools, and measuring instruments under strictly controlled environmental conditions.
The ultra precision machining method is called ultra precision machining, which is particularly important in the aerospace industry and is used to process precision mechanical parts in aircraft control equipment, such as hydraulic pumps and pneumatic servo mechanisms. Machining on a high-precision lathe can achieve a precision of 1 micrometer and a surface roughness with an average height difference of less than 0.2 micrometers, with a coordinate accuracy of ± 2 micrometers.

Precision machining technology is a key technology in modern mechanical manufacturing process systems, characterized by high precision and high quality.
It is closely related to modern mechanical design and manufacturing technology. Through the application of precision machining technology in mechanical manufacturing, product quality can be improved, creating high benefits for enterprises, and improving efficiency and quality.

Precision machining is widely used in various fields, such as aerospace, automotive manufacturing, electronic equipment, medical devices, etc.
In the aerospace field, precision machining is used to manufacture key components such as aircraft engines and missile components.

The 1950s to 1980s were the pioneering period of ultra precision machining technology. The United States was the first to develop ultra precision machining technology and developed diamond tool ultra precision cutting technology.
In the 1980s and 1990s, ultra precision machining technology began to enter the early stages of civilian industrial applications. Several companies began to launch ultra precision machining equipment and began manufacturing general civilian industrial optical components.
