Power Feed

The rotating feed rod provides powered move- ment of the carriage or the cross slide. The car- riage moves left or right along the spindle center line, and the cross slide moves in or out across the spindle center line.

Note: Using the leadscrew for powered movement of the carriage is discussed in the Threading sub- section starting on Page 40.

NOTICE

High feed rates combined with high spindle speeds results in a rapidly moving carriage or cross slide. Pay close attention to the feed rate you have chosen and keep your hand poised over the feed change lever. Failure to fully understand how to operate the power feed can lead to carriage or cross slide crash that may permanently damage the machine.

To engage the feed rod:

1.Use the spindle direction lever to turn the spindle OFF, then allow the spindle to com- pletely stop before making gear changes.

NOTICE

Always make sure the spindle is turned OFF and has come to a complete stop BEFORE changing gearing configurations to avoid the risk of permanently damaging your lathe.

2.Move the feed direction lever for the desired feed rod rotation direction and carriage/cross slide movement.

Note: All directions reverse when spindle rotation is reversed.

3.Make sure the half-nut is disengaged from the leadscrew by moving the half-nut lever up.

4.Move the feed rod/leadscrew lever to the left for feed rod rotation.

5.Use the spindle direction lever to start the spindle rotation.

6.Return the feed rod/leadscrew lever to the center position to disengage the power feed from the feed rod.

NOTICE

Never engage the half-nut with the leadscrew when using the feed rod for carriage or cross slide movement. Failure to follow this instruction will lead to permanent dam- age to the carriage and leadscrew mecha- nisms.
