Precision machining is a process that uses high-precision, rigid machine tools and finely ground cutting tools to remove an extremely thin layer of metal from the workpiece surface at very high or very low cutting speeds, very small depths of cut, and small feed rates. Obviously, this process can significantly improve the machining accuracy of parts. Because the residual area after cutting is small, and the adverse effects of cutting forces, cutting heat, and vibration are minimized, the surface alteration layer left by the previous process can be effectively removed. The machined surface has virtually no residual tensile stress, and the roughness is greatly reduced, significantly improving the surface quality.
High-precision grinding includes precision grinding, ultra-precision grinding, and mirror grinding.
