• Various kinds of works can be grinded. • Designed geometrical configuration can be achieved. • It removes little material of order 0.25 to 0.50mm. Disadvantages of grinding: • Work surface gets over heated. • Wheel wear results duplicate parts do not have the same dimensions. • Grinding is not suitable for heavy metal removing.
Abrasive wheel grinder Abrasive wheels and grinding machines come in many styles, sizes, and designs. Both bench-style and pedestal (stand) grinders are commonly found in many industries. These grinders often have either two abrasive wheels or one abrasive wheel and one special-purpose wheel such as a wire brush, buffing wheel, or sandstone wheel.
End-feed Grinding. In the end feed of centerless grinding, the workpiece is axially fed into the machine tool along one side and rests on the end stop. Perform the grinding operation, and then feed the workpiece in the opposite direction to exit the machine tool. ) Face feed grinding is most suitable for tapered workpieces.
Can be applied with a standard low speed floor machine. DISADVANTAGES: 1. Can discolor or darken some light colored grout. 2. Can cause a slight yellowing in some stones if moisture is present. (The yellowing can be removed with the appropriate chemical) 3. Possibly slippery if over buffed. 4. Has limited affect on most granites. 5.
