Micrometer Dial Collars - Just inside the handles of the tailstock (Figure5.1),
crossfeed (Figure 5.1), drill press (Figure 5.1), compound feed (Figure 5.1), and
leadscrew (Figure 5.1) there are collars calibrated in inches. The compound feed,
leadscrew, and crossfeed are calibrated in two thousandths, the tailstock in thousandths,
and the drill press in 40-thousandths.
These micrometer dial collars can move independently around the handle shafts. This
independent motion is called float. Floating dials on the cross slide, tailstock, and
leadscrew let you zero the collars at any point and read the feed travel from that point
on the dial for added accuracy.
18.
Mill Belt Tensioner - To adjust the mill belt (Figure 5.7), swing the roller assembly
to the front and place the belt on the back of the roller. Loosen the roller assembly and
slide it back and forth in its slot.
Figure 5.7 With the millhead cover off, you can adjust the mill-belt tension.
19.
Millhead Height Adjustment - Unlock the mill-head lock and place the height
adjustment handle in one of the three holes in the black collar. Turn the collar to raise
and lower the millhead.
20.
Mill Spindle - The mill spindle (Figure 5.7) attaches to the quill, which moves in and
out of the head. The quill lock keeps the quill still when you install or remove tools from
it and while milling horizontally. Usually, tools fit into collets that attach through the
spindle via drawbars.
21.
Tailstock - The tailstock, which provides right-end support for the work, moves
along the bed and can stop at any point. It has an MT3 taper and holds centers, drills,
reamers, taps and other tools. To move the tailstock spindle, turn the tailstock hand
wheel.
To offset the tailstock, adjust the two base-locking bolts (Figure 5.8). To offset to the left,
loosen the left adjusting bolt and tighten the right. To offset to the right, loosen the right
adjusting bolt and tighten the left.
