Abstract
Grinding of flat plates is performed by using a very thin, conical grinding wheel which is attached to the open end of a revolving cup and which projects outwardly from and is inclined with respect to the cup. The peripheral cutting edge of the grinding wheel revolving at high speed is brought into contact with the work. As the grinding wheel is fed, the work is cut by the grinding wheel across its thickness and an undercut part of the work disrupts (i.e. breaks off) by itself to a desired thickness. Thick grinding is also possible if a multiplicity of the grinding wheels are placed one over another at proper intervals.
