Precision parts processing introduces the main technology of precision grinding and polishing In a certain range, increasing the grinding pressure can improve the grinding efficiency. In addition, the grinding trajectory of ultra-precision grinding has the following basic requirements, maintaining the impression of the workpiece surface, the tools at each point on the surface are under the same or similar cutting conditions, and the cutting conditions are:
(1) The workpiece moves parallel to the plane of the grinding wheel, so that each point on the workpiece has the same or similar grinding stroke.
(2) A corner office of the workpiece ensures smooth movement of grinding.
(4) Make sure that the grinding disc of the workpiece on the surface of the grinding wheel is uniform, so as to ensure the flatness of the workpiece surface.
(5) Change the movement direction of the workpiece, reduce the surface roughness value, and ensure a uniform surface.
The machinery industry has experienced a high-speed development stage, precision parts processing has been adjusted from high-speed development to medium-speed, from extensive development to transformation and upgrading, and from domestic leading global changes; although some industries, enterprises drift, machinery, automobile leading enterprises, enterprise scale, products and The level of economic benefits, the international competitiveness of the machinery industry has been improved, and China plays an important role in the process from "manufacturing power" to "manufacturing power".
