With 33 years of experience selling for GCH, Jeff’s in-depth knowledge of grinders and their operation makes him a valuable resource for manufacturers worldwide. It seems that no two Cincinnati grinders were built the same, and Jeff has seen all of the various iterations. There is not a centerless problem that Jeff cannot help solve. Customers know to reach out to Jeff when their centerless, ID, OD, double disc and surface grinders are ailing or when a spindle has gone bad.  Let Jeff offer suggestions if you are looking for ways to improve tolerance or remove ‘human error” from the grinding equation.
