Description
Version:
- Slim design (4.5° contour, identical to shrink contour according to DIN 69882-8)
- With RFID/Balluffchip bore.
- Axial length adjustment, adjustment travel 10 mm.
- Reducing adapters can be used.
- Temperature resistant up to 120°C for 4 hours.
- Up to 10× more clamping operations possible compared to a standard hydraulic chuck.
- Very low tightening torque of the clamping screw – easy handling.
- Patented new hydraulic clamping system – reliable and durable premium radial run-out.
Advantage:
Same properties as shrink-fit chucks:
- Accuracy
- Extremely slim, identical interference contour
- Better damping
- Simpler to use
- Flexibility (through reducing adapters)
- No shrink-fit units required (costs, energy consumption)
Application:
Particularly for use in tool and mould making where a reduced interference contour is required.
For drilling, reaming and milling.
For clamping tools with shank tolerance h6.
For drilling, reaming and milling.
For clamping tools with shank tolerance h6.
Optional extras:
Coolant tube No. 309880, socket wrench No. 309890; reducing adapters No. 302140; 302135 302145 302147 each size 12 and No. 302150; 302155; 302160; 302165 each size 20.
Warning:
Intended use
Reasonably foreseeable misuse
- Hydraulic chuck for clamping rotationally symmetrical tools.
- For work in industrial environments.
- Observe minimum clamping depth.
- If using custom designs, observe the specifications in the applicable drawings.
- Observe the maximum operating speed and if necessary
- adjust it to suit individual circumstances.
Reasonably foreseeable misuse
- Do not use in explosion hazard areas.
- Not for use in areas where high concentrations of dust, flammable gases, vapours or solvents are present.
- Do not combine extensions.
- Not to be used for workpiece clamping.
- Do not heat with a shrink-fit unit.
