5.2. Setting the Depth and Stop
1.
Set the depth to zero by lowering the cutting
tools to the surface of the work piece.
2.
Lock the quill position by using either the quill
lock handle (N
–fig. 5) or the depth handle lock
knob (L
–fig. 6).
3.
Set the depth by rotating the depth stop knob
(P
–fig. 5).
5.3. Lowering the spindle
Lowering the spindle lowers the drilling or cutting tool.
There are two methods for lowering the cutting tool.
One method is to use the down-feed lever arms.
The lever handles are for gross and quick movements.
The second method uses the micro-feed hand wheel
which handles fine and slow movements.
5.3.1. Using the lever arms
1.
Grab the lever handle knob (B-Fig.6) and pull
down.
2.
Remember not to release the levers unless the
quill is locked or the spindle has reached the
top position.
3.
Use the lever handles (B-Fig.6) to control the
ascent when raising the spindle.
5.3.2. Using the lever arms
Use the micro-feed hand wheel to make precise
movement. Depth measurements can be monitored
precisely by observing the micro-adjusting indicator
behind the hand wheel. 1 revolution = 2.5mm or 1inch.
1.
Simply grab the handle(C-fig.7)on the hand
wheel and turn.
2.
Turn the hand wheel clockwise for down and
counter clockwise for up.
5.4.
Locking the quill
The machine head is equipped with a quill lock to lock
the depth of the spindle. It is useful for setting the tool
depth for milling and drilling.
1.
Simply rotate the quill lock handle (R-fig.8) until
tight.
2.
Rotate counter clockwise to release the quill.
3.
Leave the quill lock released when not need for
an operation.
