The free sample cutting disc is flawed when it is used. How can it reduce the defects? The following is a brief introduction to the measures to reduce the processing defects of free sample cutting disc.
- Reasonable selection of grinding amount, fine grinding method with even radial feed amount and even fine grinding. If the radial feed amount and the grinding wheel speed are appropriately reduced, the axial feed amount is increased, the contact area between the grinding wheel and the workpiece is reduced, and the heat dissipation condition is improved, thereby effectively controlling the surface temperature increase.
- Reasonable selection and dressing of the grinding wheel, the grinding wheel with white corundum is better, its performance is hard and brittle, and it is easy to produce new cutting edge, so the cutting force is small, the grinding heat is small, and the medium grain size is used in the particle size, such as 46 to 60 mesh is better. The hardness of the grinding wheel is medium soft and soft (zr1, zr2 and r1, r2), that is, the grinding wheel with coarse grain size and low hardness, and the self-excitation is good to reduce the cutting heat.
- Reasonably use the cooling lubricating fluid to play the three functions of cooling, washing and lubrication, keep the cooling and lubrication clean, and control the grinding heat within the allowable range to prevent the workpiece from being thermally deformed. Improve the cooling conditions during grinding, such as the use of oil-impregnated grinding wheels or internal cooling wheels. The cutting fluid is introduced into the center of the grinding wheel, and the cutting fluid can directly enter the grinding zone to exert an effective cooling effect to prevent burns on the surface of the workpiece.
