Enabling 5-sided and simultaneous 5-axis machining, they allow you to handle many different tasks on a single machine. Highly productive and flexible, with easy operation and maintenance, available with pallet changer or table loading. The second generation of the HF series provides numerous optimisations, including new spindle units with increased performance and the advantages of the HELLER zero-spindle system for minimised life cycle costs. Moreover, the option of a second drive in the Z-axis allows for even more universal application, including single-part production. In combination with the proven HELLER DNA of productivity, precision and reliability, they guarantee you increased performance, precision and flexibility for the production of your workpieces.

The basis is the rigid machine bed. Highly precise and fast machining cycles guarantee the unique machine structure of the HF: the fifth axis is located inside the workpiece, the directly-driven A/B-axis is supported by a counter-bearing. Basic structure Crossbed and travelling column in gate design rigid cast iron machine bed in combination with weight-optimised machine columns from steel horizontal spindle with lean spindle neck for perfect reach into the workpiece NC-rotary swivel table with counter bearing for optimum force flow and compact design gantry drive in Z axis (option) with two ball screw drives and two direct measuring systems chain-type or rack-type tool magazine for fast tool provisioning and high storage capacity tool changer with two NC axes for fast automatic tool change pallet changer with lifting/swivelling principle and robust HF pallet interface machine variant with table loading available as an alternative Kinematics Drive concept Mill-Turn (option) Open all Technical data Product selection HF 3500 HF 5500 Positioning range X/Y/Z mm 710/750/710 900/950/930 Rapid traverse speed X/Y/Z | Power (Speed) (Pro) m/min 65 (90/90/80) (90/90/80) 65 (90/90/80) (90/90/80) Acceleration X/Y/Z | Power (Speed) (Pro) m/s² 8 (10/10/8) (10/10/10) 8 (10/10/8) (10/10/10) Positioning tolerance Tp / At1) X/Y/Z | VDI/DGQ 3441 / ISO 230 | Power (Speed) (Pro) mm 0.005 (0.005) (0.004) 0.005 (0.005) (0.004) Tool shank Size HSK-A 63 (HSK-A 100) HSK-A 63 (HSK-A 100) Chip-to-chip time t₂,₃ | VDI 2852 | Power (Speed & Pro) s 2.7 (2.4) / (7.2)2) (3.3 (3.0) / (9.5)2)) 2.9 (2.6) / (7.2)2) (3.5 (3.2) / (9.5)2)) Clamping surface Nominal size mm 400 x 500 Ø 630 (Ø 710)3) 500 x 630 Ø 810 (Ø 880)3) Workpiece dimension Diameter x height mm Ø 7104) x 630 Ø 710 x 690 Ø 9004) x 800 Ø 900 x 870 Clamping load Power (Speed) (Pro) kg 550 (550) (650) 550 (550) (650) 750 750 Machine control Siemens SINUMERIK 840D sl Siemens Siemens ( ) = optional values - = not available 1) position uncertainty 2) in conjunction with rack-type magazines 3) clamping plate 4) consider limitations Product selection Positioning range X/Y/Z mm Rapid traverse speed X/Y/Z | Power (Speed) (Pro) m/min Acceleration X/Y/Z | Power (Speed) (Pro) m/s² Positioning tolerance Tp / At1) X/Y/Z | VDI/DGQ 3441 / ISO 230 | Power (Speed) (Pro) mm Tool shank Size Chip-to-chip time t₂,₃ | VDI 2852 | Power (Speed & Pro) s Clamping surface Nominal size mm Workpiece dimension Diameter x height mm Clamping load Power (Speed) (Pro) kg Machine control Siemens SINUMERIK 840D sl Product selection HF 3500 HF 5500 Positioning range X/Y/Z mm 710/750/710 900/950/930 Rapid traverse speed X/Y/Z | Power (Speed) (Pro) m/min 65 (90/90/80) (90/90/80) 65 (90/90/80) (90/90/80) Acceleration X/Y/Z | Power (Speed) (Pro) m/s² 8 (10/10/8) (10/10/10) 8 (10/10/8) (10/10/10) Positioning tolerance Tp / At1) X/Y/Z | VDI/DGQ 3441 / ISO 230 | Power (Speed) (Pro) mm 0.005 (0.005) (0.004) 0.005 (0.005) (0.004) Tool shank Size HSK-A 63 (HSK-A 100) HSK-A 63 (HSK-A 100) Chip-to-chip time t₂,₃ | VDI 2852 | Power (Speed & Pro) s 2.7 (2.4) / (7.2)2) (3.3 (3.0) / (9.5)2)) 2.9 (2.6) / (7.2)2) (3.5 (3.2) / (9.5)2)) Clamping surface Nominal size mm 400 x 500 Ø 630 (Ø 710)3) 500 x 630 Ø 810 (Ø 880)3) Workpiece dimension Diameter x height mm Ø 7104) x 630 Ø 710 x 690 Ø 9004) x 800 Ø 900 x 870 Clamping load Power (Speed) (Pro) kg 550 (550) (650) 550 (550) (650) 750 750 Machine control Siemens SINUMERIK 840D sl Siemens Siemens Downloads Product brochure 5-axis machining centres HF 3.7 MB Download At a glance, our Download Centre offers an extensive range of information materials about our company, our products and services for you to download.
