TENDO Zero
Hydraulic Expansion Toolholders
The TENDO Zero hydraulic expansion toolholder is the professional toolholder for tight tolerances for reaming, fine-drilling and finish boring – or wherever perfect run-out accuracy is essential. This enables even minimal run-out errors with tools, mountings, and the machine spindles to be individually compensated.
Description
Advantages – Your benefits
- Adjustable run-out of 0 μm possible
Run-out errors of toolholders and tools can be compensated by using four lateral set-screws - Low maintenance
The completely closed system ensures a long service life - Dirt grooves for reliable torque transmission
The enormous clamping pressure of the TENDO Zero hydraulic expansion toolholder creates a displacement of oil, grease, or lubricant residues into the groove, therefore the clamping surfaces stay dry. - Fine-balanced by default
Suitable for high speeds and high-speed cutting 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 - 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 - Broad compatibility
Can be ideally combined with TENDO SVL and TRIBOS SVL extensions - All commercially available tool shank types can be clamped
