Ask The Grinding Doc: Decrease diameter, increase speed

Dear Doc: I installed a variable-speed drive on a cylindrical grinder. The wheels start at 18" and stub-out at 15". Should I increase the rpm as the wheel diameter gets smaller? The Doc Replies: If you want more consistent grinding, maintain a constant surface speed. The basic equation is: new rpm = original rpm × original diameter ÷ current diameter.
