A new, horizontal-spindle machining centre for 5-sided and simultaneous 5-axis machining, the HF 5500, has been launched by Heller alongside the smaller HF 3500 version. With a 900 x 950 x 900mm work envelope and a maximum pallet load of 750kg, the larger machine offers approximately 200mm extra travel in X, Y and Z plus 200kg additional load capacity, says Heller.
A ‘Speed-Dynamics Package’ is an option, which the company claims shortens chip-to-chip times by 10%, and a high-speed lift-and-swivel tool changer that reduces idle times further.
Heller says the HF series allows multiple part workholding or one very large component such as a transmission case to be secured. This series of machining centres is available with a choice of four different spindles, with either an HSK-A63 or HSK-A100 taper, offering speeds up to 18,000rpm and torques to 452Nm.
