Grinding Fixture

The standard magnetic tables are used to rest workpiece like that resting surface will be parallel to the surface to be ground. Therefore, for light workpiece along with lesser resting area, the resting area tends to tilt and fly off the magnetic table because of high speed of grinding wheel and because of high feed, also. Thus, it is essential to give additional support through nesting the workpiece. This can be done through placing the solid plates around the workpiece as shown in Figure. The nest plates are held firmly through the magnetic force of table with more weight and more resting area. The nest plates surround a workpiece from outside and arrest its movement in the horizontal plane. Thus, this arrangement will help in preventing it from flying off and tilting because of high speed and feed in grinding operation.

Maximum possible area of the magnetic table should be utilized to grind as several workpieces as possible in a single batch.
