New 5-Axis HMC Features Water-Cooled Travelling Column to Eliminate the Lever Effect

F. Zimmermann GmbH has brought its first horizontal machining center onto the market. The new model range is particularly useful for efficient machining of standard components for the aircraft industry. It has two special patented features, applying to pallet handling and the travelling column.

The key element of the new FZH400 5-axis horizontal machining center is a robust water-cooled travelling column. Common designs have the drawback that their deviation increases as the slide extends, owing to a lever effect. This is not the case with the patented column design of the new FZH400. With increasing penetration into the material the guide carriage distance increases, and that increases the rigidity. The stepped drive guide ensures a perfectly constant geometry along the Z axis as well as maximum rigidity in sensitive areas of the workpiece.

Minimal Idle Times as Standard

Already in the standard version, the FZH400 features an integral pallet handling system with pallet changing during machine time. The handling system, also patented, enables reliable transport of pallets without sagging. This makes it especially suitable for long pallets. Pallets are raised and lowered in such a way that the load is balanced, thus almost eliminating bending and torsion forces.

The machine has a configurable modular design and is extremely compact. No special foundation is necessary; a standard factory floor is sufficient for anchoring. Users can thus put the machine into operation more quickly and have much greater flexibility when setting it up.
