Z-Axis Auto Feed for Sharp Mills
The Z-axis auto feed is a handy tool for making holes with consistent depth and finish.
The z-axis power feed has 4 components: (1) the selector switch, (2) the cutting depth stop, (3) the feed rate selector, (4) and the z-axis feed engage lever as seen in the picture here.

|For setting depth of cut.
Will automatically disengage quill feed slightly before final depth (roughly 25 thousandths before). To go to complete depth, bring down manually.
|Three feed rates: 0.0015”, 0.003” and 0.006” per revolution.
Use the 0.006” rate for soft materials, the 0.003” rate for hard materials and the 0.0015” rate for all finishing cuts. May be changed while still or running.

Can manually disengage by moving handle back to the when reaches depth of cut stop.
NOTE: Move Z axis down from top slightly before engaging and ensure it is traveling in the right direction. If moving in the incorrect direction, check spindle rotation direction. If spindle rotation direction is correct, and still moving up, pull or push the reverse knob located immediately above the engage lever.
