Disassembly
Hold the spindle thrust bearing with a wrench and loosen the draw-in rod 2-3 turns. Tap top
of draw rod with plastic hammer to loosen the tool from the cone. Turn the draw-in rod
further, so that the tool is released completely out from the cone.
ATTENTION!
When using an MT 3 spindle.
When installing a cold Morse taper into a heated-up machine the MT seats tend to shrink
on the Morse taper versus a quick-release taper.
4.5.3
Use of collet chucks
When using collet chucks to hold 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.
