ABSTRACT:
A reversible d.c. torque motor advances and retracts a cone mechanism for radially expanding and contracting the stones of a tool for honing a bore in a workpiece. The motor is adapted to advance the cone mechanism at three different speeds so as to effect expansion of the tool first at a rapid traverse rate, then at a slower coarse feed rate and then at a still slower fine feed rate. Pulses representative of changes in position of the cone mechanism are routed to and are counted by a reversible counter which causes the cone mechanism to retract to different starting positions as the stones of the tool wear and reduce the effective diameter of the tool.
