Installation
CAUTION!
When milling, the seat cone must always be secured with the drawbar. A simple
connection with the taper bore of the work spindle without using the drawbar is not
permissible for milling. The cone connection is released by lateral pressure. Injuries may
be caused by parts flying off.
The milling head is fitted with an M12 tie
rod.
Remove the cap.
Clean the seat in the spindle / quill.
Clean the cone of your tool.
Insert the tool in the spindle / quill.
Screw the draw bar in the tool.
Tighten the tool with the draw bar and
hold the spindle on the counter
bearing by means of a wrench.
4.5.2
Removing
Hold the spindle on counter bearing with a wrench and loosen the draw bar. Continue
turning the tie rod, so that the tool is squeezed out from the conical seat.
ATTENTION!
When using an MT spindle.
Compared to steep cone sockets when installing a cold Morse taper in a warm machine,
these MT - tapers tend to shrink onto the Morse cone seat.
4.5.3
Use of collets
If collets are used to house milling tools, higher machining tolerance can be achieved. The
collet may easily and quickly be changed for a smaller or larger end mill with no need to remove
the complete tool. The collet 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 is used for each milling cutter diameter, so that the milling cutter may be fastened
securely and firmly.
