OPERATION
The Knifeholder, ETP-KN, consists of a double-walled hardened steel sleeve filled with a pressure medium. The pressurising mechanism consists of a screw and piston with double sealing function.
When the pressure screw is tightened the double-walled sleeve expands against the shaft and creates a rigid joint. Dismantling or repositioning is done by loosening the screw.
Clamping alternative: On request the holders can be equipped with a nipple. In this case pressurising is done with a grease pump.
The hydraulic principle gives the following characteristics:
- minimal axial/radial runout
- longer lifetime for the knives
- higher feed rates
- possibility to use carbide knives
- no damages to shafts
- easy adjustments and repositioning along the shafts
