This Index G200 is a used twin-spindle CNC lathe, a type of precision machine tool — sometimes referred to as a CNC turning centre — designed for the high-productivity automated turning of bar stock and chucked components. Index is a German manufacturer with a longstanding reputation for multi-spindle and twin-spindle turning machines, serving industries that demand tight tolerances and high output volumes, including automotive, aerospace, and precision engineering.
Built in 2017 and currently located in Germany, this machine has logged 52,890 operating hours and is offered in used condition. It is equipped with a Siemens SINUMERIK CNC control system displayed on a 24-inch colour flat-panel screen, and carries CE marking. The electrical installation, dated December 2017, is rated at 400 V / 50 Hz with a control voltage of 24 V and a rated current of 68 A. An Index MBL bar feeder is included with the machine.
Both the main spindle and the counter-spindle share identical core specifications: each accepts bar stock up to 42 mm in diameter, runs to a maximum speed of 7,000 rpm, and delivers a maximum spindle power of 13 kW. Both spindles are equipped with a C-axis for contouring operations. The main spindle front bearing diameter is 85 mm and its clamping cylinder is sized D60/20, suited to gripper and chainring tooling with a single clamping pressure device. The counter-spindle uses a D42 clamping cylinder configured in the same manner. The maximum turning length is 200 mm.
The machine carries two cross carriages. Cross Carriage 1, positioned at the top and operating on X/Z axes with additional Y and B axes, uses a V-guide with W-serration configuration and holds a 14-station VDI 25 turret equipped with driven (power) tools. Its X-axis travel is 155 mm and Z-axis travel is 590 mm, with rapid traverse rates of 20 m/min on X and 30 m/min on Z. Position feedback is provided by an optical linear encoder on the X-axis and a rotary encoder on the Z-axis; the tool drive uses a dual-clutch system. Cross Carriage 2, located at the lower right and operating on X/Z axes, shares the same 14-station VDI 25 turret with power tools and V-guide construction, but has a shorter X-axis travel of 105 mm and Z-axis travel of 400 mm, with faster rapid traverses of 22 m/min on X and 45 m/min on Z. Its measuring system mirrors that of Carriage 1, while the tool drive employs a WAN system with clutch.
The combination of twin matched spindles, dual turrets with live tooling, C-axis capability on both spindles, and the integrated bar feeder makes this a well-specified machine for complete part machining in a single setup.
