    Tolerances of about +0.02 are held on rather complex grinding operations. For closer tolerances, the proportion of material removed by abrasive should be increased. The surface finish is held in the range of 0.2 to 0.4 micron on carbide and 0.4 to 0.8 micron on steel. Sharp corners are difficult to obtain and the smallest radius of 0.2 mm cannot be avoided unless a final pass without ...

    Indexing head - Wikipedia

    Indexing is an operation of dividing a periphery of a cylindrical workpiece into equal number of divisions by the help of index crank and index plate. A manual indexing head includes a hand crank. Rotating the hand crank in turn rotates the spindle and therefore the workpiece. The hand crank uses a worm gear drive to provide precise control of the rotation of the work. The work may be rotated ...
