Form Grinding

Glebar’s Centerless Form Grinding Machines are designed to grind parts as small as 0.050″ to 4″ diameter on the same machine. Spherical and cylindrical components can be shaped into unlimited forms on a large variety of materials such as rubber, carbon fiber, Teflon® (PTFE), and various metals. A multitude of applications can be ground including insulators for electronic components, fuse bodies, crystal quartz glass boules for fiber optics, check valves for pumps and valves, golf balls, and other consumer product components. Glebar has over 70 years of form grinding experience, having introduced the first compact form grinder to the market in 1952. Our history is deeply rooted in this type of grinding.
