How to choose the abrasive grain size of grinding wheel for thermal spray coating?

       The particle size is mainly selected according to the surface roughness. Under the condition of ensuring a certain surface roughness, the particle size of the small particle size number is selected as much as possible, which not only ensures the quality of the machined surface, but also can use a larger cutting amount, thereby improving the production. effectiveness.



     (1) The particle size selection range of green silicon carbide grinding wheel is 36#~80#.

     (2) Selection range of particle size of artificial diamond grinding wheel:

     The surface roughness is Ra1.25~2.5, and the particle size is 46#~60#.

     The surface roughness is Ra0.63~1.25, and the particle size is 80#~100#.

     The surface roughness is Ra0.32~0.63, and the particle size is 120#~150#.

     The surface roughness is Ra0.16~0.32, and the particle size is 150#~240#.

      (3) Selection range of particle size of cubic boron nitride grinding wheel:

     The surface roughness is Ra0.32~1.25, and the particle size is 80#~100#.

     The surface roughness is Ra0.16~0.63, and the particle size is 100#~150#.

     The surface roughness is Ra0.32~0.08, and the particle size is 150#~240#.

     The surface roughness is Ra0.16~0.02, and the particle size is 280#~W40.
