Assembly of the milling machine

- Attach the compound-type table 1 (Fig. 2) to the base 2
with the 4 x M4 Allen screws supplied.
- The milling machine must now be fastened to a stable
work surface with 4 screws 3.
Operation
Installation of the collet chucks
Disconnect the mains plug before changing tools.
Tightening the union nut without a suitable shank inserted,
damages the collet chuck.
1. Block the spindle with a spanner and release union
nut 1 (Fig. 3).
2. Insert the required collet chuck 2 using suitable inserting
tool 3.
3. Block milling spindle and re-tighten union nut.
All inserting tools must be tightened with as little protrusion
as possible. Excessively protruding shanks vibrate and
cause poor milling results.
Setting the spindle speed
The spindle speed can be adjusted continuously by means
of the electronic control.
In general:
Large milling tool diameter = low speed
Small milling tool diameter = high speed
