The Function of Scraping And Grinding Hand scraping and grinding is one of the methods for surface finishing processing. Its purpose is to reduce surface roughness, improve contact accuracy and geometric accuracy, and thereby improve the overall stiffness, lubrication performance, mechanical efficiency, and service life of the machine tool. Scraping and grinding is a necessary processing process for high-grade machine tools and cast iron flat plates. Scraping and grinding refers to the combination of two processes: scraping and grinding; is flat scraping - grinding - on flat scraping - grinding, reciprocating, alternating cycles, and continuous operation, in order to gradually reduce the surface roughness value and shape error of the cast iron flat plate; The contact accuracy and geometric accuracy gradually improve during operation until they finally meet the specified requirements. The tools used for scraping and grinding machining are simple, versatile, and have minimal machining allowance. The guide rails, support plates, and bearing shells of machine equipment with high precision requirements are all precision machining using scraping and grinding methods.
