The BT bed type milling machine is highly dynamic, stable and precise. It is perfect for roughing and finishing. The BT can also be used with large cutter heads in wear-resistant materials. The machine's high weight and ribbed cast iron construction minimise vibrations and promote precision. Another special feature is the generously dimensioned INA linear guideways and the Heidenhain inline drive. All this ensures that the BT bed type milling machine works quickly and efficiently. The BT can be converted into a multitasking machine by selecting a mounted or integrated rotary table or carousel turning tables for 5-sided machining or turning.
- Heavily ribbed, vibration-damping cast iron construction of the entire machine
- INA linear guideways on all axes
- Highly dynamic digital drives (25,000 mm/min)
- 43 kW main spindle motor
- Enclosure on 4 sides with 2 front doors and one door at the rear
- Ergonomic handling of workpieces on the machine table thanks to offset front doors
- Interface compatibility
- Effective chip management
- Multitasking: milling and turning on one machine
