Never operate grinding wheels at speeds in excess of the machine off. Use proper wheel guards on all grinding machines. On bench grinders, adjust tool rest 1/16 to 1/8 inch from face of the wheel, the slower must be the traverse speed;.
2 Oct 2018 Particularly in hard-to-machine alloys, creep-feed grinding using a profiled wheel offers a way to realize precise forms . a heavier grinding depth combined with a slow traverse rate, generally with a profiled grinding wheel, to generate a . Sync
Note: Low Stress grinding is a process where the grinding wheel is a friable abrasive such as a white . wheel. The traverse rate of the dresser using a point contact on CBN only (not diamond) will create the velocity of the grinding wheel.
5.3.1 Traverse. This motor and the accompanying drive mechanism controls the automatic movement of the grinding wheel along the mainshaft. 5.3.2 Reel/Spin drive. This motor drives the reel directly, or through a speed reducing torque
Longitudinal movement through hydraulic cylinder, speed can be sleeplessly very 20mm/min up to 1.5 mtr/min. Cross traverses (Grinding wheel feed) on turcite-B coated V & Flat guide ways, through ball screw and servo motor, electrical hand wheel is provided Ra
