Lathe / Mill / Drill Clutch - The lathe/mill/drill clutch (Figure 5.4) are inside the
gearbox. A three-position clutch, it transfers power to either the lathe or the mill, but not
to both at the same time. To engage it, rotate it slowly while pushing or pulling on the
clutch sleeve. Pulling it to the left runs the lathe, to the right (all the way in) runs the
mill/drill. The middle is neutral.
14.
Lathe Spindle - The end of the lathe spindle face in the tailstock is the spindle nose.
The spindle nose, which has an MT4 taper, rotates the workpiece and drives lathe chucks
and other work holding devices. All attachments such as three and four jaw chucks bolt
to the spindle flange either directly or via an adapter plate.
15.
Leadscrew - The leadscrew, which runs the length of the bed, moves the carriage
for lathe turning or thread cutting. It works both manually and under power. You can also
use it manually with the mill.
16.
Locks - Locks on the cross slide (Figure 5.3) carriage (Figure 5.1), quill (Figure 5.6),
and tailstock (two), Figure 5.1 and 5.7, keep them from moving. During machining, lock
all lock except the one on the part you want to move.
Figure 5.6 The quill moves in and out of the millhead, carrying the spindle.
