Precision machining technology refers to all kinds of machining processes whose machining accuracy and surface finish are higher than those of the corresponding machining methods. Precision machining technology includes precision machining (such as diamond boring, precision turning, wide edge precision planing, etc.) and high-precision grinding. The machining accuracy of precision machining is generally 10~0.1 μ m. The tolerance grade is above it5, and the surface roughness Ra is 0.1 μ Below M.
Features: precision machining is a process of cutting a very thin layer of metal on the surface of the workpiece with very high or very low cutting speed, small cutting depth and feed rate by relying on high-precision and rigid machine tools and fine grinding tools. Obviously, this process can significantly improve the machining accuracy of parts. Because the residual area of the cutting process is small, and the adverse effects of cutting force, cutting heat and vibration are eliminated to the greatest extent, the surface metamorphic layer left by the previous process can be effectively removed. After machining, the surface is basically free of residual tensile stress, and the roughness is greatly reduced, which greatly improves the quality of the machined surface.
Function: high finish and high precision grinding also requires high precision and rigidity of the machine tool. The grinding process is to use a finely trimmed grinding wheel to produce multiple equal height micro cutting edges on each abrasive particle. With a small grinding depth and under appropriate grinding pressure, very fine chips are cut from the workpiece surface, plus the friction, extrusion, smoothing effect when the micro cutting edge is in a micro state, and the friction and polishing effect of multiple non feed smooth grinding stages, Thus, high machining accuracy and high smooth surface with good physical and mechanical properties can be obtained. To sum up, the precision machining process can comprehensively improve the machining accuracy and surface quality of the workpiece.
