4.7.2
Unfitting
Loosen the nut on the draw-in rod and hit the draw-in rod gently with a rubber mallet to
remove the tool from the holding taper of the spindle sleeve.
ATTENTION!
When installing a cold morse taper into a heated-up machine those MT seats tend to
shrink on the morse taper contrary to the quick-releaser tapers.
4.7.3
Use of collet chucks
When using collet chucks for the reception of milling tools, a higher operation tolerance can be
achieved. The exchange of the collet chucks for a smaller or larger end mill cutter is performed
simply and rapidly and it is not necessary to disassemble the complete tool. The collet chuck is
pressed into the ring of the swivel nut and must rest there by itself. The milling cutter is clamped
by fastening the swivel nut on the tool. Make sure that the correct collet chuck is used for each
milling cutter diameter, so that the milling cutter may be fastened securely and firmly.
4.8
Clamping the workpieces
CAUTION!
Injury by flying off parts.
The workpiece is always to be fixed by a machine vice, jaw chuck or by another
appropriate clamping tool such as for the clamping claws.
4.9
Adjusting the rotational speed
ATTENTION!
Wait until the drilling-milling machine has come to a complete halt before changing the
speed using the gear switch.
There are two levers to switch over the gear to the desired spindle speed at the front side of the
machine. In combination with the electric stage circuit of the drive motor (17) on the control
panel, there are the following speeds.
