CELSIO Dual Contact

CELSIO Dual Contact

Heat Shrink Toolholders Dual Contact
CELSIO with simultaneous taper and flat work surface closes the interface-related gap between tool flange and the front of the machine spindle with the interface of the flat work surface. The heat shrinking technology system can be used for all types of shrinking devices.
When applying heat shrinking technology for thermal tool clamping, the tool shank is shrunk in the heated tool mounting. An inductive coil creates rapidly changing eddy currents which act on the heat shrinking toolholder directly and apply concentric to the precise point where the tool shank will be inserted. The result is an almost homogeneous unit, as if the heat shrinking toolholder and tool are a single piece.

Advantages – Your benefits

  • High clamping forces
    Safe and friction-locked clamping for transmission of high torques
  • Good ratio between radial rigidity and interfering contour
    High machine-cutting performance and quicker machining times for increased productivity
  • Toolholder for powerful metal cutting
    High-speed machining of machine speeds up to 50,000 RPM and for use of HSS and HM tools
  • Run-out accuracy ≤ 0.003 mm measured according to DIN 69882-8 in the clamping bore
    Optimum surface results, high precision processing and safe processes due to uniform cutting action and highest reproducibility
