Axial driven tool holder with external/internal cooling (for subspindle). Maximum 6.000 rpm.
Axial driven tool holder (directed to the subspindle), with coupling DIN 1809, for collets ESX/ER 32 and external/internal cooling. Maximum 6. 000 rpm.
Valid for machines
Tool holder typeCMZ
Maximum speed 6.000 rpm.
External and/or internal cooling (70 bar max.)
The internal cooling is realized by a floating gasket with grafit sealing with drain to the exterior, which avoids any type of contamination of the bearings.
The outlet of the coolant must always be activated during the rotation of the tool holder in order to ensure the lubrification and thus prolong the lifetime of the sealing.
Maximum coolant pressure 70 bar.
Interior perfectly sealed with PTFE rotating gaskets and a layer of ceramic on the axis in the contact areas. This is of vital importance and the ensurance of a much longer lifetime of the tool holder (it is widely known that the intrusion of coolant through the sealing is in general the principal reason for the deterioration of tool holders).
The rotating axis of the tool holder is tempered and rectified (NOT hard-turned as done by other manufacturers).
