Description
Version:
- Taper ground internally and externally with RFID/Balluffchip bore.
- Concentricity and repetition accuracy 3 μm at 3×D, maximum 50 mm when using a HP precision collet.
- HDC = Heavy Duty Chuck, a mount specially designed for rough machining. A reinforced chuck body ensures better stability and plenty of radial stiffness. Taper ground internally and externally. Ball-bearing clamping nut with trapezoidal-shaped fine thread for optimum tightening torques and clamping forces, reduces vibrations that occur.
- Very high clamping forces due to the collet fully seated in the chuck and coated clamping nut.
- Vibration damping due to the element collet and mass of the chuck.
- Alternatively for CENTRO P -> without seals, with ER clamping nut CP No. 309655 or sealed system with ER clamping nut CP for HP sealing rings No. 309665 in conjunction with HP sealing rings No. 309666 − 309668 (for internal coolant supply or as a dirt trap).
Ventaja:
Al realizar la sujeción, el asiento óptimo patentado de la pinza portapieza, las guías dobles, la rosca trapezoidal y la tuerca de apriete con recubrimiento deslizante se unen, formando una unidad estable y garantizando el máximo de rigidez y precisión.
Aplicación:
Para la sujeción de alta precisión de herramientas con mango cilíndrico. HDC especialmente adecuado para fresas de desbastado (entre otros TPC) y operaciones de acabado o mecanizado de materiales altamente resistentes o tenaces.
Volumen de suministro:
Sin tuerca de apriete.
