Hoffmann launches 5-axis vice with spindle quick-change system


Hoffmann Group has introduced its new GARANT Xpent 5-axis vice at IMTEX 2017. The vice is optimised for 5-face machining and can be quickly and easily adapted to any machining strategy. Flexible clamping options are ensured by the construction and variability of the clamping modules, which can be rotated by 180 degrees.

The new GARANT Xpent is suitable for components ranging from 6 to 986 mm (6 to 386 mm in its standard configuration) and offers a clamping force of up to 40 kN with 90 Nm of torque. Up to 100 mm of travel are possible without conversion, while a modern quick-change system enables rapid spindle replacement. The spindle can be extended and features a trapezoidal thread to facilitate rapid adjustment of the clamping ranges.

The GARANT Xpent is based on a flexible, modular design concept. This allows the clamping range to be adjusted through individual combination of the clamping modules, base rail and spindle. The convex clamping modules can be rotated by 180 degrees for utmost flexibility of the vice.

Another highlight is the sophisticated and comprehensive top and front jaw system. The jaws are hardened, ground and applied with a special coating to ensure accurate, process-reliable machining. The front jaws can be replaced quickly and easily.

In addition, transverse slots enable precise alignment of the perfectly symmetrical 5-axis vice on the machine table. GARANT ZeroClamp bores in the base rail and a comprehensive range of accessories complete the feature set.
