In a grinding apparatus, an end of a tubular workpiece (10) is finished, preferably with a chamfer, by grinding while the workpiece is positioned in a holder (14) and rotated about the workpiece axis. A rotatable grinder (22) is carried by a carriage (90) that pivots the grinder in a plane that is radial to the axis whereby the grinder is moved between operative and inoperative positions. In a preferred arrangement, the grinder (22) is lowered into engagement with the workpiece by an actuator (180) acting against a constant upward biasing force. <IMAGE> |
