With the machines, the company promises high productivity in series production and for universal application when machining medium to large batch sizes. At EMO Hannover 2017, the manufacturers will be spotlighting the HF 3500 model for table loading, first presented in 2016 and providing a work envelope of 710x750x710 mm and a maximum table load of 550 kg, and the new model HF 5500 equipped with pallet changer. This latter version has a work envelope of 900x950x900 mm and a maximum pallet load of 750 kg. In terms of kinematics, the exhibitors point to the three linear axes in X, Y and Z and two direct-driven rotary axes in A and B on the swivel rotary table. Depending on the application, a total of four spindle versions are available. A Siemens control and a double pivoting main operator panel with a 24-inch touch-screen and a newly developed user interface allow easy operation. Standardized pallet automation solutions from Fastems or Schuler are said to contribute to efficient production processes.
Five-axis machining centers with reduced idle times
With the fifth axis provided by the workpiece, the five-axis machining centers from the Heller HF series are claimed to significantly reduce idle times in combination with powerful dynamics and a horizontal spindle for short chip-to-chip times.
