Centerless Grinding – Feed Regulating Wheels

Good

CUMI Abrasives manufactures and supplies centerless grinding feed regulating wheels for through-feed, in-feed and end-feed operations. On a centerless grinder, the grinding wheel removes stock while the regulating wheel controls how the component rotates and feeds. Both need tightly matched geometry and density to wear evenly across a multi-wheel set. CUMI builds each wheel with premium abrasive grains and specially designed vitrified, resin and rubber bond systems, and customises the specification for your component, machine and finish target. Manufacturers in the aerospace, automotive, bearing, steel and general engineering industries use CUMI centerless grinder wheels to hold stringent size and surface-finish requirements.
