Removing a tool
• Hold the spindle with the wrench and loosen the draw-in rod. Turn the draw-in rod
further so that the tool from the cone admission is squeezed out.
Use of collet chucks
When using collet chucks for the reception of milling tools, a higher operation
tolerance is possible. The exchange of the collet chucks for a smaller or larger end
mill cutter is performed simply and rapidly and the disassembly of the complete tool
is not required.
The work spindle is equipped with a surface for the hold-up with a fork wrench to
unfasten the swivel nut of the collet chuck retainer. The collet chuck is pressed into
the ring of the swivel nut and must hold there by itself. By fastening the swivel nut on
the tool the milling cutter is clamped.
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.
4.4 Clamping workpieces
Tools or collet chucks with a MT2 shank may be clamped directly into the work
spindle. For mounting these tools, proceed as described in ‘inserting tool’ above.
Make sure that the tool is clamped with the draw-in rod.
The workpiece is always to be fixed by a machine vice, jaw chuck or other
appropriate clamping tool.
