White Corundum Grinding Methods And Lapping Tools Are Introduced

White corundum grinding methods and lapping tools are introducedWhite corundum can be applied to mechanical engineering, abrasive abrasives and other fields.White corundum grinding method and lapping tool introduction.Grinding methods can generally be divided into wet grinding, dry grinding and semi-dry grinding 3 categories. 0 Wet lapping: also known as sand lapping, the liquid lapping agent is continuously added or coated on the grinding surface, and the abrasive is constantly sliding and rolling between the workpiece and the lapping tool to form cutting motion. 2 Wet lapping is generally used for rough grinding, and the particle size of the micro-powder abrasive is thicker than W7. Dry grinding: also known as sanding grinding, the abrasive evenly embedded in the surface layer of the lashing tool, white corundum grinding only 1 in the lashing tool surface coated with a small amount of stearic acid mixed fat and other auxiliary materials. Dry grinding is often used for fine grinding, and the particle size of the micro-powder abrasive is smaller than w7. @ Semi-dry grinding: similar to wet grinding, the grinding agent used is a paste grinding paste. Grinding 1 can be done either manually or on a grinding machine. Before grinding the workpiece, other processing methods must be used to obtain higher pre-machining accuracy, and the grinding margin is generally 5 to 30 microns.The lashing tool is to make the workpiece grinding forming tools, but also the carrier of the abrasive agent, the hardness should be lower than the hardness of the workpiece, and there is a certain wear resistance, commonly used gray cast iron made. The metallographic structure of the wet lashing tool is mainly ferrite; The dry lapping tool is made of uniform and fine pearlite as matrix. Soft steel lashing tools are commonly used when grinding threads below M5 and small workpieces with complex shapes. White corundum grinding holes and soft metal materials, most of the yellow copper, copper lashing tool. The lashing tool should have sufficient stiffness, and its working surface should have high geometric accuracy. The lashing tool is also subjected to cutting and wear in the grinding process, such as proper operation, its accuracy can also be improved, so that the processing accuracy of the workpiece can be higher than the original precision of the lashing tool.
