Three point Contact
Three-point contact live centers make it possible to hold workpieces with an "out-of-round" internal diameter condition. With a conventional full cone center, the workpiece rests on the high points of the internal diameter and may shift with the pressure of the grinding wheel. This tends to copy the out-of-round condition of the part piece I.D. and gives poor surface finish to the workpiece.
Full Service Guarantee.
