METHOD FOR GRINDING HARD AND BRITTLE MATERIAL

摘要

PURPOSE:To always perform both tooling and dressing by constituting a device in such a way that a grinding stone for dressing is bonded onto the surface including sections to be ground of a work, and performing grinding accompanied with the cutting of said grinding stone. CONSTITUTION:A grinding stone for dressing 3 is bonded onto a work 1. Grinding for hard and brittle materials such as rock crystals, glass and the like is performed by a blade 2 accompanied with cutting of the grinding stone for dressing 3 at all time. Accordingly, the blade 2 is subjected to the act of both tooling and dressing by the grinding stone for dressing 3 while the work is being processed, it may thereby perform the processing on the work 2 with optimum grinding performance kept at all time. When the grinding stone for dressing 3 is bonded onto the surface including sections to be ground of the work 1 (bonded surface 5), the sections to be processed of the work 1 is also firmly fixed on the grinding stone for dressing as well. This constitution thereby prevents internal stresses from being incurred into the work 1 more than necessary, and also prevents the sections to be processed from being cracked because of internal stress.
