■ General Purpose Machines 1. If the machine cannot achieve the standard spindle speed, please use the max. spindle speed available. 2. If cutting noise and vibration are present, please reduce the cutting conditions accordingly. 3. For groove milling of Stainless steel,use 60% of recommended spindle speed and 40% of recommended feed rate. (*)
