Summary

The INDEX G200.3 and G220 are CNC turn-mill centers designed for integrated turning and advanced 5-axis milling of bar and chuck parts. Featuring up to three simultaneous tool carriers, both models offer flexible machining for parts up to 900 mm in length and bar diameters up to 76 mm, with the G220 incorporating a dedicated motor milling spindle for complex 5-axis operations. Differentiators include simultaneous multi-tool operation and an optional integrated workpiece handling system configurable for shaft and flange parts.

Key Capabilities

• Simultaneous turning and 5-axis milling (G220) with Y/B quill kinematics
• Three independent tool carriers, each with Y axis capability
• Identical main and counter spindles for complex front/back machining
• Modular automation options: workpiece handling unit, double gripper, turret steady rest, and robot cell (iXcenter)
• Accommodates workpieces up to 900 mm length and 230 mm diameter (chuck)
• Siemens S840D sl CNC control with 18.5" multi-touch screen
