3.Rotate both speed controls knobs all the way counterclockwise. This will prevent power feeds from starting table movement when power feed unit is turned ON.

4.Reconnect machine to power.

5.Position grinding wheel above workpiece without making contact. This position will be used to test run limit stop setup.

6.Select automatic operation by turning X-axis mode selector switch to the right (pointing at “table” symbol).

7.Turn X-axis speed control knob clockwise to slowly begin table travel.

8.Make sure grinding wheel travels desired dis- tance over workpiece in X-axis.

—If grinding wheel does not travel desired distance over workpiece, rotate X-axis speed control knob all the way counter- clockwise to stop table travel, then reposi- tion X-axis limit stops.

To prevent damage to power feed unit, ONLY stop table travel by rotating speed control knobs all the way counterclockwise. Do NOT use ON/OFF switch or mode selec- tor switches to stop table travel.

9.Stop X-axis table travel by rotating X-axis speed control all the way counterclockwise.

10.Hold Y-axis mode selector all the way to left (pointing at “T” symbol) to jog Y-axis table movement, and make sure grinding wheel travels the desired distance over workpiece in the Y-axis.

—If grinding wheel does not travel the desired distance over workpiece, rotate Y-axis mode selector to the center (pointing at “hand” symbol), then reposition Y-axis limit stops.

11.Using the Z-axis handwheel, lower grinding wheel until it just touches the highest point of workpiece surface.

Note: Better results are attained with multiple light passes than a few deep passes.

12.Start coolant flow and grinding wheel rota- tion.

13.With both mode selector switches rotated to the right (pointing at “table” symbol), rotate the speed control knobs to the desired table travel speed.

Note: When table completes one side-to-side cycle in X-axis path, then table will travel for a short time along the Y-axis path and stop. The distance the table travels along Y-axis path depends upon setting of Y-axis speed control knob.

You can reverse Y-axis direction any time by pushing the Y-axis reverse button.

14.Allow the grinding wheel to surface the desired workpiece surface until there are no more sparks generated before lowering the grinding wheel with Z-axis crank for addi- tional surfacing.

Do NOT leave machine unattended when operating in power feed mode to prevent an unexpected occurrence from damag- ing machine/workpiece or causing a safety hazard.
