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.
Advantage:
Patented optimum seating of the collet, double guides, trapezoidal fine thread and ball-bearing mounted 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 shank.
HDC especially well-suited for roughing (including TPC milling) and finishing operations and machining of high-tensile or tough materials.
