Abstract:

A honing machine having capability to hone surfaces at different angular orientations using rocking motion to produce the stroking when honing in one orientation and linear motion to produce the stroking when honing in a different angular orientation, including a support structure mounted for linear movement on a rail and an arm assembly extending from the support structure, the arm assembly being pivotal on the support structure to produce the rocking motion in the one orientation of the support structure, the arm assembly moving with the support structure in the other angular orientation thereof to produce the linear movement thereof. The machine also includes latch device to maintain the support structure in the one orientation thereof. The latch device includes a mechanism to control the limits of stroking in the one orientation, and it includes apparatus to counterbalance the arm assembly. The latch device operates to deactivate the counterbalance apparatus when the support structure is moved to its other orientation.
