ThermoGrip® TMG shrink lining
Extreme holding forces - Our new TMG is characterized by exceptional flexibility, high rigidity and optimized vibration damping.
FIELD OF APPLICATION APPLICATION
Application: General mechanical engineering, medical and dental technology, die and mold making, renewable energies
Features
- Constant maximum clamping forces
- Reliable clamping of all shank tolerances from h4 to h9
- Pull-out protection for Weldon shanks
- Concentricity accuracy ≤ 3 μm
Benefit
Increase in the metal removal rate
Excellent damping properties therefore better surfaces and better adherence to tolerances
One basic holder for all diameters
M stands for constant maximum clamping forces.
Due to the constant maximum overlap of tool and chuck, the design guarantees constant maximum clamping forces. The sleeve is also available with pull-out protection (Weldon).
M stands for added value.
For the first time, TMG is clamping tools of almost any diameter with one and the same shrink fit chuck. This means that the entire production requirement can be covered cost-effectively and flexibly with a small number of basic holders.
One shrink fit chuck for all diameters
Transmittable torques with 16 mm shank diameter
The new Bilz TMG clamping system combines the strengths of shrink-fit clamping technology with the flexibility of collet chuck solutions. The system consists of basic holders and specially coated collets.
Shank tools from 2 to 32 mm can be clamped with previously unattainable clamping forces, e.g. more than 850 Nm with a 20 mm tool shank. This takes place in a fully automatic or manually
innovative process on induction shrinking devices.
Comparison of manual and automatic shrinking on the ISG 3460
Manual shrinking
- Place the device in the shrinking position of the induction unit.
- Place the tool holder in the tool carrier of the device.
- Bring the tool holder into the clamping position by loosely turning the drive shaft counterclockwise until the mechanism locks.
- Insert the collet chuck into the tool holder and screw it in by hand until a stronger resistance can be felt (approx. 3 turns).
- Insert the machining tool into the collet chuck.
- Select the appropriate shrink parameters according to the tool holder and insert the correct interchangeable disk.
- Start the shrinking process, whereby the holding time must be activated.
- After heating the tool holder, the processing tool is clamped by turning the drive shaft clockwise. The cooling process depends on the respective induction shrink unit.
Automatic shrinking
- Place the tool carrier and chuck in the shrink position of the induction unit.
- After selecting the shrinking parameters on our touch display and inserting the correct ferrite disk and coil, the shrinking process can be started by pressing the (Start) button.
- Insert the collet chuck into the tool holder and screw it in by hand until the elastic stop can be felt (approx. 3 turns). The collet chuck only needs to be applied to the axial stop with a low torque. The tool can then be inserted into the collet.
- The shrinking process is continued by pressing the (start) button.
- With the ISG3460-WK, the shrink chuck is lowered into the cooling unit and then the coil is raised to the upper end position. After the cooling time, the chuck is slowly moved upwards and dried with compressed air. It can now be removed by the operator
The new Bilz TMG clamping system combines the strengths of shrink-fit clamping technology with the
flexibility of collet chuck solutions. The system consists of basic holders and specially
coated collets.
Safe clamping and unclamping is carried out in a fully automatic or manual process
on our induction shrink units from the ISG3XXX series upwards. Both the shrinking process and the
and the associated chucks are patent-pending and only available from us.
