Hydraulic Expansion Toolholders
Hydraulic expansion toolholder with manual actuation and closed clamping system for high-precision and economical tool grinding.

Advantages – Your benefits

  • Optimized interfering contour
    A 30 to 40% slimmer interfering contour compared to our standard hydraulic expansion toolholders, for significantly improved interference between grinding wheel and toolholder
  • Extremely large clamping depth
    Special tools with large shank lengths can be clamped up to 95 mm deep
  • High level of flexibility
    Clamping of different diameters due to the use of slotted or coolant-proof intermediate sleeves
  • Repeat accuracy < 0.003 mm, measured on the tool shank
    Process reliability as well as best surface quality and shape accuracy due to uniform cutting edge action
  • Permanent run-out accuracy of the cutting edges
    Better chip flow, more even cutting action, significantly increased tool life, as well as increased cutting speed and feed rate
  • High clamping forces
    Safe tool clamping even with short clamping depths or high interference between grinding wheel and toolholder is guaranteed
  • Excellent vibration damping
    Micro-blowouts are prevented, best workpiece surfaces, machine spindle protection, increased tool service life resulting in cost reductions
  • Micron precise tool change in seconds without peripheral equipment
    Time saving through reduction of set-up time and no investment and energy costs due to additional clamping devices
  • Exact length preadjustment
    Length adjustment in the range of 0.01 mm accuracy, with adjustment travel of 10 mm
  • Broad compatibility
    Can be ideally combined with TENDO SVL and TRIBOS SVL extensions
