Travel Adjustment
The lifting handle can be used to control the travelling of the spindle box.
1. Loosen the screw inside the spindle box.
2. Rotation of the lifting handle will move the spindle box up or down.
Fine Feeding
To operate the fine feed, push the clutch lever in. This will enable the handwheel for the fine feed.
Mitre Wedge Adjustment
In the long term wear will occur on the dovetail. This will cause inaccuracy that can be eliminated by
adjusting the mitre wedge (adjusting the dovetail gib strip). Adjusting the screw slides the tapered strip to
reduce the gap and restore accuracy of the mill.
The following adjustments are possible
:
1.
Base & Y­Axis Cross Slide
.
2. X­Axis Cross Slide & Work Table
3. Mill Head Seat & Vertical Column.
4. Mill Head & Spindle.
The Way To Adjust
1. Loosen the locked nuts.
2. Adjust the foremost pressure of the mitre wedge by locked nut. If necessary, loosen all the
adjusting screws to the same.
3. Tighten and loosen the adjusting screws, also keeping the pressure of each adjusting screw
the same.
4. Tighten the locked nut uniformly.
5. When the nut is locked, please use the #3 interior hexagonal wrench to fix the adjusting screw
from rotating (this will cause an unbalance in the pressure).
6. Please adjust the middle portion first and then go to toward the interior from two sides
uniformly while you are adjusting the screw in order to ensure uniform pressure.
