Overview

The INDEX G200 is a flexible manufacturing turning center from INDEX-Traub's G-series lineup, offering dual-spindle, dual-turret mill-turn capability in a compact, highly productive platform. The G200 represents INDEX's approach to the turn-mill segment: a highly automated machine that maximizes productive time per cubic meter of floor space by combining the main spindle, counter-spindle, and two turrets with live tooling into a single machine cell that can complete complex turned and milled parts in a single setup.

The main spindle handles parts up to 65 mm (2.56 in) bar diameter with a 6,000 RPM maximum speed and 15 kW (20 hp) motor. The counter-spindle mirrors the main spindle's capability, enabling true simultaneous back-working where the counter-spindle machines the back face and secondary features while the main spindle completes the front face on the next part. Upper and lower turrets each carry 12 live tool stations, providing 24 total tool positions for complex programs requiring extensive tooling arrays.

INDEX's iXpanel control system — built on Mitsubishi CNC with INDEX's proprietary programming interface — provides a user experience optimized for turn-mill programming with graphical cycle support for complex mill-turn operations. The machine's compact footprint of approximately 3,800 x 2,300 mm makes it practical for job shops where floor space efficiency matters. The integrated bar feeder interface enables automatic bar feeding for unattended production runs.

At $350,000-$500,000 new, the G200 competes with the DMG Mori NLX 2500, Mazak QT-Nexus 250-II, and Doosan/DN Solutions Lynx 300 in the small-to-mid turn-mill class. INDEX machines command a premium over Korean competition based on German engineering quality and long-term reliability in high-utilization production environments.

Strengths & Limitations

Strengths

Dual-spindle, dual-turret configuration completes complex parts front and back in a single machine cycle — zero repositioning error
24 total live tool positions (12 upper + 12 lower) support complex programs with extensive tooling requirements
Y-axis (±60 mm) on both turrets enables off-center milling and eccentric features without C-axis limitations
Simultaneous back-working with counter-spindle minimizes dead time between front and back operations
INDEX German build quality and reliability track record in 24/7 automotive production environments
Compact footprint at ~3,800 x 2,300 mm provides high productivity per square meter of floor space

Limitations

$350K-$500K investment is 2-3x the cost of a comparable single-spindle turn-mill machine from Korean manufacturers
iXpanel control with Mitsubishi base is capable but less familiar than Fanuc in most North American shops
INDEX's North American dealer network is smaller than DMG Mori, Mazak, or Doosan/DN Solutions
65 mm bar capacity limits the G200 to smaller-diameter work — the G300 extends this to 76mm
Complex dual-turret programming has a steeper learning curve than single-turret alternatives

Best For

Precision job shops running complex turned and milled parts requiring both front and back machining in automated cycles Medical device manufacturers producing stainless and titanium components requiring complete machining in a single setup Automotive suppliers machining complex shaft, fitting, and housing components in medium-to-high volumes Shops seeking European turn-mill quality with a smaller footprint than full mill-turn machining centers Operations running bar-fed unattended production on complex parts where dual-spindle completion minimizes work-in-process

Frequently Asked Questions

01 How does the INDEX G200 differ from the G300?

The G300 handles larger bar diameters up to 76 mm (3 in) versus the G200's 65 mm maximum, and has a larger turning envelope. The G200 is more compact and appropriate for smaller parts. Both share the dual-spindle, dual-turret architecture and iXpanel control.

02 What is the iXpanel control on the INDEX G200?

The iXpanel is INDEX's proprietary programming interface built on a Mitsubishi CNC platform. It provides graphical cycle support, part program simulation, and INDEX's proprietary programming cycles for turn-mill operations. Standard ISO G-code is supported alongside the graphical interface. Most programmers comfortable with turn-mill CNC adapt to iXpanel within a few weeks.

03 Can the G200 run completely unmanned?

Yes, with a bar feeder interface and sufficient tooling in the 24-station tool complement, the G200 can run extended unmanned cycles producing complete front-and-back machined parts from bar stock. Tool life monitoring, broken tool detection, and alarm management support unattended operation within the programmed tool life windows.

04 What does a new INDEX G200 cost?

New G200 machines typically price between $350,000 and $500,000 depending on configuration, Y-axis options, and accessory selection. This is a significant premium over comparable Korean turn-mill machines, reflecting INDEX's German engineering and the dual-turret configuration's productivity advantage.
