Advantages – Your benefits

  • No interfering contour
    Optimal freedom of movement where working space is limited
  • Fine-balanced by default
    Suitable for high speeds with a balancing grade of G2.5 at 25,000 RPM
  • 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
  • Permanent run-out and repeat accuracy of < 0.003 mm
    Even cutting action, increased tool service life, and reduced costs for regrinding or buying new tools
  • Excellent vibration damping
    Micro-blowouts are prevented, best workpiece surfaces, machine spindle protection, increased tool service life resulting in cost reductions
  • Exact length preadjustment
    Length adjustment in the range of 0.01 mm accuracy, with adjustment travel of 10 mm
  • High degree of flexibility
    Clamping of different diameters due to the use of slotted or coolant-proof intermediate sleeves
  • Broad compatibility
    Can be ideally combined with TENDO SVL and TRIBOS SVL extensions
  • Dirt grooves for reliable torque transmission
    Dry clamping surfaces, by displacement of oil, grease or lubricant residues into the dirt groove
