Abstract
A surface grinder includes a bed or base, a table supported on the bed for reciprocating movement and a grinding wheel supported on a vertical column. An actuator connected to the table reciprocates the table relative to the grinding wheel. A programmable control system is operatively connected to the actuator to move the table from a home position to a feed or ramp-in position through a cutting motion, through a wipe cycle or spark out motion and to return the table to the home position. The part to be ground is held on the table by a magnetic chuck. The control system includes a manually operable teach input device which permits the operator to program the control system to set the table motion while manually moving the table through a grinding cycle. The control system provides accurate bidirectional control over the motion of the table. The operator may independently vary the speed of the table between its movement between various positions during programming.
