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.309666 − 309668 (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. 309402 − 309419 (not for Holex), ER CP clamping nuts No. 309655; 309665, ER HDC clamping nuts No. 309657, HP sealing rings No. 309666 − 309668, CP roller bearing wrenches No. 309754; 309756, HDC roller bearing wrenches No. 309745/309756.
