The new INDEX G220 Turn-Mill Center includes a motorized 5-axis milling spindle and a tool turret with Y-axis, providing enhanced machining flexibility for turning and milling complex parts in a single set-up. INDEX will demonstrate the machine at IMTS 2014.
With a distance of 1,280 mm between the main and counter spindle and a maximum turning length of 1,000 mm, the G220 provides a generous work area. Operators have easy access to the main and counter spindles, the turret and the motorized milling spindle, as well as the operating panel.
The fluid-cooled, identical main and counter spindles feature a clearance of 65 mm (chuck up to max. 250 mm diameter), provide power of 20/24 kW (100%/40%), a torque of 135/190 Nm and a maximum speed of 5,000 RPM.
A tool turret located in the lower part of the machine can accommodate VDI 25 and VDI 30 tool mountings in 18 or 12 stations, all of which can be equipped with individually driven tools (power 6 kW, torque 18 Nm, speed 7,200 RPM).
The fluid-cooled 5-axis motorized milling spindle (power 11 kW, torque 30 Nm, speed up to 18,000 RPM) has hydrostatic bearings in the Y and B axes. The stable circular guide is designed to further ensure rigidity and damping. The Y-axis features a +/-80 mm stroke, the B-axis driven directly by a torque motor has a swivel range of -35° to +215°. With a large travel distance in the X-direction, machining at up to 30 mm below the turning center height is possible.
The motorized milling spindle operates using a one- or optionally two-row tool chain magazine that features space for 70 or 140 tools (HSK-A40). The double-row tool magazine enables set-up during machining time.
The compact machine features a CNC-controlled programmable gantry-type removal unit for finished workpieces. It can unload remnants from the main spindle as well as finished parts from the counter spindle.
The G220 features the latest generation INDEX C200 SL controller. Based on the Siemens Sinumerik 840D sl (solution line), it features an 18.5" touchscreen. The operating panel features a second input, which INDEX uses for its own Virtual Machine (VM) program simulation (option). By pressing a button, the operator can switch to "VM on Board" and make use of simulation, regardless of current machine operations.
