What is the difference between precision and ultra-precision machining in mold manufacturing

At present, precision machining technology is no longer an isolated machining method and pure craftsmanship, but has become a systematic project with extremely extensive content. To achieve ultra-precision machining, not only ultra-precision machine tools and tools are required, but also an ultra-stable environment. It also needs to use computing technology for real-time detection and feedback compensation.

In the actual operation of the mold manufacturer, look at some brief introductions about precision machining and ultra-precision machining:

1) Ultra-precision cutting processing: such as using diamond tools for ultra-precision cutting and processing various mirror surfaces. It has successfully solved the processing of large paraboloids used in laser nuclear fusion systems and astronomical telescopes. (Guide: Description of the guide parts of the two major parts of the mold)

2) Ultra-precision grinding and abrasive processing: such as the surface processing of high-density hard disks and the processing of large-scale integrated circuit substrates.

3) Precision and special processing: For example, on large-scale integrated circuit chips, using electron beam and ion beam etching methods to produce patterns, the minimum line width that can be achieved at present is 0.1.

Through the above practice, it is proved that only by combining the technical achievements in various fields can it be possible to realize and develop ultra-precision machining.
