Index G220

The generous work area of the G220 forms the basis for equal implementation of milling and turning in one machine design. The configuration of the machine is designed to provide a maximum of flexibility independent of the primary use of the machine. The dynamic and powerful motorized milling spindle allows the production of demanding workpieces – even using fiveaxis machining. Moreover, the lower tool turret with a Y-axis and a powerful tool drive ensures the possibility of three-dimensional machining on the main and counter spindle.

Benefits Features Specifications

Fast tool change
High dynamics (up to 55 m/min rapid traverse speed)

The turn-mill center G220 with its dynamic motorized milling spindle is ideal for machining of complex workpieces – up to five-axis machining. With a high degree of rigidity, thermal and dynamic stability and vibration damping – also thanks to the Y/B-axis running in hydrostatic bearings – workpieces can be completely machined from six sides with high productivity and precision.
Generous work area designed for turning/milling or milling/turning
2 powerful, identical motorized spindles (up to 40 kW and 310 Nm)
Lower tool turret with Y-axis (100 mm) and 18 or 12 stations
Simultaneous machining with two tool carriers possible
Already included: the operating system iXpanel i4.0 ready with 18.5” touch screen – based on Siemens S840D sl
