Heller Machine Tools will show its second-generation HF 3500 5-axis horizontal machining centre (HMC) model at MACH. The company will also feature the fourth generation of its H-Series 4-axis HMCs on Stand 130 in Hall 20.
The HF 3500 Gen2 and the larger HF 5500 are available with a fixed table or an automatic pallet changer. Both are built-in Redditch and incorporate improvements over the previous generation. Both machines are offered with either an HSK-A63 or HSK-A100 tool interface in three versions, POWER, SPEED and the new option of PRO, the latter intended for long periods of simultaneous 5-axis machining.
Designed to raise cutting performance, innovations include halving the minimum distance between the spindle nose and the centreline of the 225-degree swivelling trunnion; the availability of twin motors and ballscrew drives and the offer of six new spindles. Other notable improvements include increased stiffness of key components, shorter chip-to-chip times and faster tool change from a chain-type magazine with up to 240 pockets or a rack-type magazine with up to 405 positions. The high-end PRO package additionally offers 10m/s2 acceleration in X, Y and Z.
On the HF 3500 there is the new availability of a pair of DC (dynamic cutting) universal direct-drive motor spindles, HSK-A63/16,000rpm 56kW and HSK-A100/12,000rpm 45kW. To minimise non-productive times, Heller has succeeded in achieving a big reduction in run-up times for the new spindles, maximum revs are now reached in 1.4 seconds for the HSK-A63 variants, 1.8 seconds for HSK-A100. All spindles feature Heller’s Zero-Spindle system for rapid interchangeability, leading to maximum machine availability coupled with low service costs.
Featured at MACH 2022 will be Heller4Industry, the group’s worldwide drive towards integration of its machine tools and controls into the Industry 4.0 environment. Within the multi-faceted portfolio is HELLER4Operation, an easy-to-use, operator-oriented user interface.
The HELLER4Services interface focuses on transparency of digital manufacturing and maintenance and the HELLER4Performance includes workpiece-specific analysis for optimisation of a process and extraction of real-time data over the internet, plus evaluation and graphical display in the cloud.
