Description

Version:

  • Ground externally and internally 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. Ball-bearing clamping nut with trapezoidal-shaped fine thread for optimum tightening torques and clamping forces reduces vibration.
  • 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 Centro P No. 309655 or sealed system with ER clamping nut CP for HP sealing rings No. 309665 in conjunction with HP sealing rings No.309666309668 (for internal coolant supply or as a dirt trap).

Advantage:

Patented optimum seating of the collet, double guides, trapezoidal thread and low-friction coated clamping nut amalgamate when clamped into a sturdy unit, thus ensuring a very high degree of rigidity and precision.

Application:

For high precision clamping of tools with plain shanks.

Supplied with:

Without clamping nut.

Optional extras:

Coolant pipe No. 309880, socket wrench No. 309890, precision ER collets for HP No. 309368 − 309381, and for taps No. 309402309419 (not for Holex), ER CP clamping nuts No. 309655; 309665, ER HDC clamping nuts No. 309657, HP sealing rings No. 309666309668, CP roller bearing wrenches No. 309754; 309756, HDC roller bearing wrenches No. 309745/309756.
