TENDO ES
Hydraulic expansion toolholder
TENDO ES with zero interfering contour is used, when every millimeter in the machine room counts. The extremely short hydraulic expansion toolholder from SCHUNK is perfectly suitable for machining large workpieces – even in confined spaces in the machine room – and deep-hole drillings.
Description
Advantages – Your benefits
- No interfering contour
Optimal freedom of movement where working space is limited - High level of flexibility
Clamping of different diameters due to the use of slotted or coolant-proof intermediate sleeves - Fine-balanced by default
Suitable for high speeds with a balancing grade of G2.5 at 25,000 RPM - Micron-precise tool change within 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 < 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, optimal workpiece surfaces, machine spindle protection, increased tool service life resulting in a reduction of costs - Exact length preadjustment
Length adjustment in the range of 0.01 mm accuracy, with adjustment travel of 10 mm - Comprehensive 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 - All commercially available tool shank types can be clamped
Form A: with smooth cylindrical shank, shank form A in accordance with DIN 1835 and DIN 6535 HA Form AB: with flat face and cylindrical shank with pulling face, shank form B in accordance with DIN 1835 and DIN 6535 HB Form B: with lateral pulling faces, shank form B in accordance with DIN 1835 Form E: with inclined clamping face, shank form E in accordance with DIN 1835 and DIN 6535 HE - Maximum radial rigidity
The machine-side mounting taper is supported in the spindle, resulting in maximum radial rigidity at high torques and plenty of additional space in the machine room
Options and special information
- Flexible clamping areas due to the use of intermediate sleeves
Intermediate sleeves allow clamping of various shank diameters from 3 - 32 mm with just one toolholder. Your advantage: Reduction of the acquisition costs, higher clamping force at the given shank diameter.
