1 Introduction 

The precision processing technology refers to various processing technologies whose processing precision surface brightness are higher than that of the corresponding processing methods. The precision machining process includes precision cutting (such as diamond boring, precision turning, wide-blade precision planing, etc.) high-gloss high-precision grinding. The precision of precision machining is generally 10 ~ 0.1μm, the tolerance level is above IT5, the surface roughness Ra is below 0.1μm.

 2 Features

Precision cutting is the process of cutting off a very thin layer of metal on the surface of the workpiece with high very low cutting speed, small depth of cut feed, relying on high precision rigid machine tools precision sharpened tools. Obviously, this process can obviously trek the machining accuracy of parts. Due to the small residual area in the cutting process, the reverse effects of cutting force, cutting heat vibration are eliminated to a great extent, so the surface transformation layer left by the previous process can be effectively removed, the surface after processing is basically free of residual The pull-down stress roughness are also greatly reduced, which greatly traverses the quality of the processed surface.

3 Classification

High-gloss high-precision grinding includes precision grinding, ultra-precision grinding mirror grinding.

4 effect

High-gloss high-precision grinding also requires high precision rigidity of the machine tool. The grinding process is to use precision-trimmed grinding wheels to produce multiple equal-height micro-cutting edges on each abrasive grain, with very small grinding Depth, under the appropriate grinding pressure, cut very fine chips the surface of the workpiece plus the friction when the micro-cutting edge is in a slight condition, kneading, smoothing effect repeated non-feeding polishing process Effect, then obtain a high-gloss surface with high processing accuracy excellent physical mechanical properties. In summary, the use of precision machining technology can comprehensively trek the machining accuracy surface quality of the workpiece.
