Abstract
A drum grinding wheel includes an elongated drum configured for coaxial engagement with a spindle of a grinding machine. An exterior surface of the drum extends parallel to a central axis, and a plurality of removable cutters are removably fastened to the exterior surface. Each of the cutters has a plurality of ribs disposed in spaced relation thereon, and abrasive grain is disposed on a grinding face of each of the ribs, such as by use of a metallic braze.
Claims34
A drum grinding wheel comprising:
- an elongated drum having a central axis;
- the drum configured for coaxial engagement with a spindle of a grinding machine;
