Disassembly
Hold the spindle thrust bearing with a wrench and loosen the draw-in rod. Turn the draw-
in rod further, so that the tool is squeezed out from the cone admission.
ATTENTION!
When using an MT 3 spindle.
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.
4.5.3
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 mil-
ling cutter may be fastened securely and firmly.
