Axial driven toolholder ER25 H60 with internal cooling 70bar (12000rpm)

Axial driven toolholder ER25 H60 with internal cooling 70bar (12000rpm)

CodeTTS/10400/02

Valid for machines

Maximum speed 12.000 rpm.
External and/or internal cooling (70 bar max.)
Maximum clamping diameter of Ø16 mm.
Collets type ESX/ER 25 (not included).
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.
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).
The toolholder is designed with a fastening nut system for the ER25 compact type collet. This way - with the collet ER32 closer to the bearings and a larger bearing diameter - the toolholder presents a significantly increased stiffness.
Please remember that the fastening of the collet, while the toolholder is mounted on the turret, damages the guidance for the drive keys on the turret.
