Metallographic Abrasive Grinding

Metallographic Abrasive Grinding

Thus, for larger hard specimens higher grinding/polishing pressures increase stock removal rates, however higher pressure also increases the amount of surface and subsurface damage. Note for SiC grinding papers, as the abrasive grains dull and cut rates decrease, increasing grinding pressures can extend the life of the SiC paper.

Surface Grinding Machine is a machine in which a grinding wheel is used as a cutting tool for removing the material from the surface of the workpiece. It is also called an abrasive machining process where abrasives are placed on the surface and corners of the grinding wheel so as to do the finishing process with much more accuracy.

Subsurface Damage In Grinding Of Brittle Materials ...

May 30, 2018 Machining-induced damage severely affects surface and subsurface integrity in grinding of brittle materials. In this paper, a predictive model of subsurface damage (SSD) is proposed that takes into account grinding parameters and spindle dynamics. Results show that the grinding depth affects SSD, and the model neglecting the effect of tool forced vibration underestimates damage.
