With the 5th axis provided by the workpiece, the 5-axis machining centre from the HF series deliver a significant reduction in idle times in combination with the powerful dynamics and a horizontal spindle for shortest chip-to-chip times
Machine concept: robust and highly dynamic
The new HF series of 5-axis machining centres proves once again that HELLER genes like productivity, performance, reliability and availability form the foundations of each and every new development from Nürtingen. The HF series combines proven qualities with innovative features. This is also true for the kinematics with three linear axes in X, Y and Z, equipped with absolute measuring systems and two direct driven dynamic rotary axes in A and B integrated into a swivel rotary table. Dynamic, because the high speed of the A and B rotary axes is achieved through minimised mass moment of inertia and the use of direct drives. Optionally, the powerful dynamics can be increased further with the “Speed-Dynamics Package”. Contrary to comparable machines on the market, HELLER has equipped the new series with a counter bearing as a unique selling point. The use of the counter bearing in combination with a YRT bearing results in high rigidity also in case of high loads.
Spindle units: class-leading quality made by HELLER
Combined with the 5th axis provided by the workpiece for dynamic 5-sided and simultaneous 5-axis machining, HELLER's typical horizontal spindle, ensuring quick tool changes and short idle times, offers substantial advantages as far as productivity is concerned. The HF provides a wide choice of spindles to suit different applications.
Work area: adequately dimensioned and ergonomically designed
Moreover, the HF series provides large workpiece interference contours. Contrary to conventional 5-axis machining centres, HELLER's concept is not only based on single-part clamping, but provides the possibility of multiple clamping or the clamping of very large components. To provide sufficient space in the work area, the workpiece interference contour of model HF 5500 was increased by 800mm in height and 900mm in diameter compared to model HF 3500, equalling a difference of 27 percent.
Operation: convenient and practice-oriented
With the HF series, HELLER is presenting its new HELLER Operation Interface, the new operating panel with 24" screen technology and touch controls, quick access technology in the control and XTENDS optional expansion applications to support the user.
