Measurement of the roundness of center holes

Linear Measurements


For controlling precision arbors, shafts and other components based on their centers it is necessary to manufacture the center holes and tail-stock centers with precision and to provide for a small displacement of the tail stock.

The production methods of the component's center holes should ensure their coaxiality with minimum deviations, for which purpose it is necessary to machine the centers and after thermal treatment grind simultaneouslyboth center holes on special center-grinding machines with the rotating component in the horizontal position. After grinding, the holes should be lapped by means of cast-iron laps.
