Graduated Dials
SECTION 6: ADJUSTMENTS
The graduated dials on the handwheels for the
table can be indexed or “zeroed” to help make
accurate and convenient movements. Each dial
can be reset or locked with the setscrew or thumb
screw provided.
Example:
Suppose you want to drill a series of holes
in a workpiece at 0.625" (
5
⁄
8
") centers. After
locating the first holes placement and
drilling, you can set the dial of the appropri-
ate axis to zero and move the table 0.625".
Drill the next hole and proceed as above.
Figure 7.
Align pin with holes.
You have two options for spindle height adjust-
ment: a drill press style, levered downfeed and a
fine downfeed handwheel. The lever is located on
the right, forward portion of the head. The fine
downfeed handwheel is to the left.
To operate the feed lever:
Pull the lever toward you. The spindle will go
down until you stop pulling or until it hits the depth
stop. The orientation of the handle may also be
repositioned.
1.
Pull the handle hub away from the head
casting.
2.
Note there is a pin behind the hub. Rotate
the handle to a new location and push the
hub towards the head casting. The pin must
align with holes in the head casting before
the hub will seat properly.
See Figure 7.
3.
Loosen the setscrew on the knurled surface
of the handwheel dial. Turn the dial until the
“0” lines up with the index line. Tighten the
setscrew.
4.
Turn the handwheel according to the dis-
tance you want to move downward. Each
complete revolution equals 0.100".
Locking:
For milling operations, the quill height can be
locked in by tightening the black lever on the for-
ward, right hand portion of the head.
