Workholding towers, grey cast iron

4-sided workholding tower with integrated UNILOCK clamping modules EFM 138. The integrated clamping modules enable the rapid clamping or exchange of clamping equipment and fixtures on the workholding tower. Set-up times are reduced and machine running times increased.

Material
Workholding tower GJL 300.
Clamping module case-hardening steel.

Version
Workholding tower contact faces precision machined.
Clamping module contact faces hardened and ground.

Note
These 4-sided workholding towers conform to machine tables for machine tools acc. to DIN 55201 and JIS6337-1980.
The clamping modules are actuated via a central pneumatic connection.
The high clamping forces are generated via the integrated spring package (the unit clamps while not under pressure).
Clamping is released pneumatically.

The following clamping forces are possible with the UNILOCK clamping bolt in conjunction with M10, M12, M16 fastening screws:

- Clamping force (M10) 35,000 N/module
- Clamping force (M12) 50,000 N/module
- Clamping force (M16) 75,000 N/module

Clamping force with DIN EN ISO 4762 -12.9 cap screws

Clamping bolts may only be clamped in conjunction with a mounted interchangeable unit in the clamping module.

Temperature range
+5 °C to +60 °C.
