Precision work refers to various machining processes in which the work accuracy and surface finish are higher than the finish machining of each corresponding work method. Such operations include precision cutting (diamond boring, precision turning, wide edge precision planing, and other machining methods), high finish, and high precision grinding.
The machining accuracy of precision machining is generally controlled from 10μm to 0.1μm, its tolerance level is above IT5, and the surface roughness Ra should be controlled below 0.1μm. Precision machining is to rely on high precision, rigid machine tools and finely sharpened tools, using a very high, slow cutting speed, very small depth of cut, feed in the workpiece surface to cut a very thin layer of metal process.
This process can significantly improve the machining accuracy of the part. Because the area left by the cutting process is small, the adverse effects of cutting force, cutting heat, and vibration are largely excluded, so the surface deterioration layer left by the previous process can be effectively removed. After the precision machining process is completed, the surface of the part is basically free of residual tensile stress and the roughness is significantly reduced, which improves the quality of the machined surface to a great extent.
