For your safety, any adjustment
on machine should be made
with power disconnected.
5.4 Gib Adjustment
After long or hard use, any “play” noted in the table mechanism or headstock column may be taken up by
adjusting the “gibs” (wedges) located in the slide mechanisms. Periodic checking and adjusting of the gibs
will assure continued machining precision and avoid chatter.
5.3 Adjust Tip Angle of Headstock
(1) Turn off main power before adjusting
(2) Hold the headstock firmly to avoid damaging
the machine or injury to the operator.
(3) Loosen the lock nut (a) with large wrench (b).
(4) Adjust the headstock to the desired tip angle
(45˚ maximum left or right).
(5) Tighten lock nut with large wrench.
Adjustment procedure:
1. Loosen the lock nuts.
2. Back off all set screws.
3. Tighten each set screw carefully until gentle
contact is made. Work from the center
screw alternately outward. Assure slides
move smoothly without play and without
binding.
4. Tighten the lock nuts uniformly (hold the set
screw with the provided hex key to prevent
unwanted rotation of the screw), and again,
check for smooth, play-free operation.
The following items may need adjustment:
1. Base and saddle seat sliding faces.
2. Saddle seat and working table sliding faces.
3. Headstock seat and connecting strut sliding faces.
4. Headstock and spindle box slide face.
Note: Leave the spindle box at the highest position
when the machine is idle.
6.1 Method of Operation
Drilling or Deep Milling
1. Follow instructions in section 5 to install cutters. Be sure cutters are held tightly.
2. Select appropriate speed level.
3. Use vise or hold down clamps to attach workpiece to the milling table.
4. Adjust worktable (Longitudinal Axis Y) and Saddle seat (Cross Axis X) in position.
5. Adjust the column limit block to proper position.
6. Put adjusting tools in order and remove all obstacles around the machine.
7. Turn on the main power. Adjust appropriate spindle speed for drilling or deep milling.
8. Refer to the scale on headstock to determine drilling or milling depth.
9. When completing the operation, turn off power and move the spindle to full up position.
10. Clean the machine.
