Study on the Effect of Coarse Grinding Area Slope Angle on Surface Quality in Point Grinding

摘要

There is a vitrified bond CBN point grinding wheel with coarse grinding area slope angle 9. This new grinding wheel has higher removing rate and better machining accuracy than conventional wheels. The design and manufacture principle of the new grinding wheels are studied in this paper. These wheels with different coarse grinding area slope angle θ are used to grind the stepped shaft of QT700 with a series of grinding parameters.VHX-1000E microscopic system and Micromeasure system are used to measure the surface quality of workpiece. In the same group of grinding parameters, compare the effect of these different wheels on surface roughness. The effect of deflection angle a on surface roughness is generalized.
