MAKING A CNC CUTTER GRINDER

摘要

Some twenty years ago I built a Quorn cutter grinder; it has been one of the most useful pieces of workshop equipment I have ever made. I bought a copy of Prof. Chaddock's book on the Quorn. It is a valuable reference for any workshop even if you do not own a Quorn. In the book a description is given on sharpening milling cutters. The end mill teeth are easy to sharpen but the fluted edges are a more difficult operation. I made a set of guide hobs as described in the book and although successful, in some sizes the pitch does not match the pitch of the cutter. The solution is to grind the cutting edge and the flute and from that point the cutter will always match the hob. This point is made in the book.
