Comprehensive investigation on mechanisms of dry belt grinding on AISI52100 hardened steel

In order to further understand the grinding mechanisms of dry belt grinding process, this paper provides a comprehensive investigation both on the evolution of the belt wear and the evolution of part's surface texture, simultaneously. The results have shown that grains' wear mode can be evaluated by surface roughness parameters Sz, Sdq and Spc. The belt wear in open-loop belt grinding has been quantitatively proved to keep stable after a few of turns due to constant working conditions. The blockage has been found in this paper and primary studied. It has been revealed that the blockage can further improve the surface roughness, ignoring the limit set by original working condition, but with a sacrifice on material removal and waviness improvement.
