Heller Machine Tools’ HF series five-axis horizontal machining centers are for machining complex prismatic parts from lighter, smaller workpieces to heavier workpieces up to 800-kg table load. In the series of two machines, the fifth axis is provided by the workpiece on a swiveling trunnion with rotary table or a pallet changer for higher volume production. Users can specify from a range of four spindle packages based on the material they are to process, with spindle speeds up to 18,000 rpm and torque up to 354 Nm available, the company says.

According to the company, the HF 5500 offers a work area of 900 × 950 × 900 mm (X/Y/Z), and the smaller HF 3500 has a work envelope of 710/750/710 mm (X/Y/Z). With three linear axes in X, Y and Z and two rotary axes in A and B integrated into a rotary table on a trunnion, the HF machines are designed for five-sided machining and simultaneous five-axis machining. The machines may alternatively be equipped with a lift-and-rotate pallet changer for series five-sided production while standardized pallet automation solutions may be supplied by Fastems or Schuler, the company says.
