Figure 40. Fine downfeed and quill auto-

downfeed system components.

A.Auto-Downfeed Rate Selector: Selects one of three auto-downfeed rates.

B.Quill Auto-Downfeed Selector: Changes downfeed control between manual downfeed or auto-downfeed.

C.Quill Dog: Disengages the auto-downfeed clutch lever as it moves with the quill to stop or reverse quill movement.

D.Auto-Downfeed Stop: Sets the maximum depth of the quill.

E.Auto-Downfeed Stop Lock: Locks the auto- downfeed stop in position.

F.Quill Lock: Locks the quill in position.

G.Auto-Downfeed Scale: Shows the posi- tion of the auto-downfeed stop (marked in inches).

H.Auto-Downfeed Clutch Lever: Engages the auto-downfeed gearing to move the quill.

I.Fine Downfeed Handwheel: Moves the quill approximately 130 of the distance that the coarse downfeed handles moves it.

J.Auto-Downfeed Direction Pin: Starts (in or out), stops (middle), or reverses direction of the quill when in auto-downfeed mode.

Quill Auto-Downfeed

1.Turn the spindle motor OFF, and wait for the spindle to stop.

2.Rotate the quill auto-downfeed selector clock- wise to the ENGAGE (rear) position.

3.Adjust the auto-downfeed stop to the desired depth, then lock it in place.

Note: The increments marked on the auto- downfeed stop represent 0.001" of quill move- ment, with one full revolution equal to 0.010" of quill movement.

4.Move the auto-downfeed direction pin to the center (neutral) position.

Note: The auto-downfeed direction pin has three positions—in, center, and out. Moving the pin to the in or out positions will start or reverse quill movement. Move it to the center position to stop the quill movement.

5.Position the auto-downfeed clutch lever to the right so that the gearing is disengaged.

6.Turn the spindle motor ON and start spindle rotation.

7.Move the auto-downfeed rate selector to the setting that is correct for your operation.
