The perfect 4-axis machining centre must be configurable to your needs, produce reliably even under maximum loads and offer a fair price/performance ratio. Our solution: HELLER H series 4-axis machining centres. Reliable components that have been tried and tested in series production over many years, combined with high dynamics, ensure robust processes – even when pushed to the limit, 24/7 in 3-shift operation. Key facts _horizontal 4-axis machining centres with pallet changer   as standard _designed for high process stability and highly resilient   right to the limits _top performance and...

Machine concept The foundation of productivity The rigid design and topology-optimised structural components provide the foundation for the high cutting performance and accuracy of our H series 4 axis machining centres. So you get the best quality – and high productivity.

Basic structure _high stability and damping in the force flow through   topology-optimised cast iron structural components _thermo-symmetric design and optimum distribution of   forces _wide range of rugged machining units   _wide choice of tool magazines, in chain-type or rack-type   design _tool changer with two NC axes for fast automatic tool change   Kinematics _machine bed supporting the X and Z axes in cross bed design   _machine column moves in X-direction and supports the   machining unit _machining unit moves in Y-direction, compact and robustly   integrated into the machine column...

Machining units Highest precision Spindles ‘made by HELLER’ are one of the highlights of our H series 4-axis machining centres. Our in-house manu facturing expertise ensures that they deliver the highest machining quality and, above all, process stability and maximum cutting performance. Special plus: the HELLER zero spindle system. If the worst comes to the worst, the machining spindle can be replaced quickly and easily. Tool shank SK/BT for selected units available as a lternative
