During the grinding operation, the control wheel 24 is in frictional driving engagement with the work piece 20, so that the work piece is driven in a direction and at a speed determined by the direction and speed of rotation of the control wheel 24. As shown, the grinding wheel 12 is mounted on a laterally movable carriage 32, while the work piece centers or supports 22 are mounted on another laterally movable
Grinding machine with resilient control wheel AMERICAN. The disclosed grinding machine comprises a grinding wheel which is driven at a relatively high surface speed, a pair of centers or other means for rotatably supporting a work piece which is to be ground, and a control wheel which frictionally engages the work piece and is adapted to rotate the work piece at a relatively low surface speed

Jul 01, 2020 Resin bonding enhances the efficiency of centerless grinding and produces a more resilient wheel. Like a grinding wheel, a regulating wheel is made of an abrasive material but usually is bonded with rubber or some other similar substance. As the name implies, a regulating wheel regulates the speed of a part as it is rotated against a grinding

The grinding wheel is the actual tool of the CNC grinding machine. Grinding wheels are rotationally symmetric tools whose abrasive grits are held together by means of a bond. The sharp edges of the abrasive grits remove material by means of cutting when they come into contact with the part to be ground. Grinding wheels are very complex tools

Vibration in grinding machine is hard to measure. It is witnessed from the formation of waviness on the work piece and grinding wheel. The major causes of vibration in grinding machine are misalignment and unbalancing. These unwanted vibrations will reduce the life of both machine and tool, resulting in loss of production
