Index’s G220 turn-mill features a motorized, five-axis milling spindle and a Y-axis tool turret to increase flexibility for turning and milling complete parts in a single setup.
The work area offers a distance of 1,280 mm between the main and counter spindle with a maximum turning length of 1,000 mm. According to the company, operators have easy access to the main and counter spindles, the turret and motorized milling spindle as well as the operating panel.
The fluid-cooled, identical main and counter spindles feature a 65-mm clearance with a 250-mm maximum chuck diameter, and they provide power of 20/24 kW (100 percent/40 percent), 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 accommodates VDI 25 and VDI 30 tool mountings in 18 or 12 stations, all equipped with individually driven 6-kW, 18-Nm, 7,200-rpm tools.
The 11-kW, 30-Nm, 18,000-rpm spindle has hydrostatic bearings in the Y and B axes. The Y axis features a ± 80-mm stroke, while the B axis is driven directly by a torque motor and features a swivel range of -35 to +215 degrees. With a large travel distance in the X direction, machining from 30 mm below the turning center height is possible, the company says. The spindle operates using a one-row tool chain magazine (two-row optional), which offers space for 70 or 140 tools (HSK-A40). The double-row tool magazine can be set up during machining.
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 Index C200 SL controller is based on the Siemens Sinumerik 840D sl (solution line), and features as 18.5" touchscreen. The operating panel features a second input, which Index uses for Virtual Machine (VM) program simulation.
