INDEX G200

The INDEX G200 is a high-performance turn-mill center from INDEX-Werke in Esslingen, Germany, designed for complex chucked parts and bar work up to 76 mm diameter. With a main spindle and counter spindle, up to three tool carriers with Y-axis capability, and a milling spindle reaching 7,200 RPM, the G200 delivers complete machining of precision components in a single cycle. It's the machine you see in medical device shops, automotive tier 1 suppliers, and hydraulic component manufacturers where every part needs turning, milling, drilling, and cross-machining done in one setup.

The main spindle handles bar stock up to 76 mm diameter and chuck parts up to 230 mm, with maximum spindle speeds reaching 6,000 RPM and power output of 24 kW at 40% duty cycle (20 kW continuous). The counter spindle matches this capability for back-end machining, and the automatic part transfer between spindles is seamless. The 660 mm maximum turning length accommodates most shaft-type components, while the 165 mm chuck diameter suits the majority of chucked work in the sub-200 mm range.

The milling spindle operates at 7,200 RPM with 22 kW of power and 52 Nm of torque through an HSK-A40 interface. This is enough for serious milling operations — cross-holes, flats, keyways, and even complex contoured features — without the chatter and deflection you'd get from live tooling in a standard turret. Up to three tool carriers can work simultaneously, with a maximum tool pool of 42 stations (VDI25) shared across main and counter spindle operations. This simultaneous machining capability is where the G200 earns its keep, cutting cycle times by 30-50% compared to sequential processing.

The machine runs on the INDEX C200-4D control, which is built on the Siemens SINUMERIK 840D platform with INDEX's proprietary programming environment. INDEX's Virtual Machine simulation software lets operators prove out programs offline before cutting metal, which matters when you're making $50 parts from $200 bar stock. Compared to the Citizen Cincom or Star SR series for bar work, the G200 handles significantly larger diameters and more complex milling operations. Against the DMG Mori CTX beta 1250 TC, the G200 is more compact and faster on small-to-medium parts but can't match the CTX's turning diameter for larger chucked work.
