Abstract
This report deals with the possibility of ductile mode grinding of optical glass BK7 by means of the metal bond diamond wheel with #140 coarse grain seize. Although the grinding modes such as ductile, ductile & fracture, and fracture modes are affected by the depth of cut, table speed, and grinding speed e.t.c, measuring the topography of working wheel surface just after the dressing is a key factor performing ductile mode grinding of BK7. The detailed observation of the behavior of cutting edges and the cutting edge distribution was examined under various grinding conditions using the newly constructed equipment. As the result, the optical surface in surface roughness was 43nm rms, 207nm Ry in ductile mode grinding.
