Sep 01, 2018· In a production-grinding operation,waviness on the part surfaceis a potential clue that the machine or process has developed a vibration problem. The effect might be seen in inspection, or if there is a lapping or polishing step, more time might be spent during that step removing the waves.

The "active" center approach to isolating harmfulmachine vibrationsis illustrated in Figure 6. Removable "active" centers are installed in a manner identical to dead centers. These devices detectgrindingforces and provide dynamic force compensation to minimize harmfulmachine vibrationsfrom causing errors in the surface of the workpiece.
