Description

Power chuck TOPlus

Six to win

  • 25 % higher holding power than SPANNTOP
  • Unequalled rigidity due to full-surface contact of the clamping segments
  • Insensitive to dirt through the clamping head geometry
  • Absorbs vibration
  • Optimal lubrication thanks to lubricating grooves in the clamping head
    reception
  • Minimal inertia loss compared to 3-jaw chucks

Unequalled rigidity

Up to 25 % more clamping force and higher output – with the same clamping cylinder that is used to actuate our SPANNTOP chucks. The pyramid arrangement of glide surfaces makes it possible. The clamping head rests with full-surface contact in the TOPlus chuck body – even with large workpiece tolerances.

Insensitive to dirt

In addition this geometry ensures that TOPlus is significantly less sensitive to contamination than previous chuck/clamping head solutions, and with a concentric precision of approx. 0.015 mm [for chuck size 65]! Thus TOPlus is even better suited for raw material, cast and forged parts, as well as fi ne-particle non-ferrous metals such as brass. Therefore, all-round optimized values make the chuck an ideal partner for modern manufacturing strategies and state-of-the-art machine tools.

Intelligent version

And the sensor variant, TOPlus IQ, can even monitor the clamping force that actually occurs on the workpiece and initiate changes in the clamping force.

Combi pull-back

Workpiece clamping with pull-back effect. Chuck with dismountable endstop plate. Without end-stop plate ideal for machining pipes and bars.

Advantages

  • Workpiece stabilization through axial draw force applied against the workpiece end-stop
  • Prepared for inside and front end-stop
  • Converts to a fully functional »bar chuck« when the end-stop plate is removed

Combi deadlength

Workpiece clamping without pull-back effect. Chuck with dismountable endstop plate. It is also frequently used on the sub spindle.

Advantages

  • Workpiece clamping without axial movement of the clamping head
  • Clamps workpieces with a short collar or shoulder
  • Suitable for pick-off without pullback effect
  • Prepared for inside and front end-stop
  • Converts to a fully functional »bar chuck« when the end-stop plate is removed

Modular

Through-bore chuck only – ideal for machining pipes and bars.

Advantages

  • Fully-functional bar chuck
  • Due to pull-back effect significantly more rigid clamping is achieved than by conventional collets
  • Higher RPM and metal removal rates for bar work
