INDEX Werke / INDEX Traub CNC Lathes and Turn-Mill Centers
The German machine tool manufacturer INDEX Group, operating under the INDEX and TRAUB brands, manufactures precision CNC turning machines, turn-mill centers, multi-spindle automatic lathes, and Swiss-type sliding headstock machines for high-precision manufacturing.
INDEX C100 and C200 High-Speed Production Turning Machines
INDEX C100 and C200 high-speed turning machines are engineered for productive bar machining of complex parts up to 65 mm or 90 mm diameter. Equipped with two or three tool turrets on SingleSlide guideways, they execute concurrent cutting with minimal chip-to-chip times and thermal rigidity.
- Bar clearance capacity of 65 mm or 90 mm with chuck turning diameters up to 175 mm
- Up to 3 tool turrets operating simultaneously with SingleSlide guideway dampening
- Synchronized main spindle and counter-spindle with hydraulic clamping systems
- Replacement VDI live tool drives, hydraulic cylinder seals, and linear slide carriages
INDEX G200 and G220 Turn-Mill Machining Centers
INDEX G200 and G220 turn-mill centers deliver complete 5-axis simultaneous machining of complex workpieces in a single setup. Equipped with a motorized milling spindle on hydrostatic B-axis guides and a lower turret, the machine mineral cast bed ensures superior dynamic vibration dampening.
- High-rigidity motorized milling spindle with hydrostatic B-axis guide support
- Mineral cast machine bed providing rigid vibration dampening and thermal stability
- Lower 12-station VDI 25 tool turret with independent driven tool tooling drive
- Spindle bearing cartridges, Heidenhain optical linear scales, and servo feed motors
INDEX MS24-6 and MS40-8 Multi-Spindle Automatic Lathes
INDEX MS24 and MS40 multi-spindle automatic lathes feature six or eight spindles for high-volume mass production. The ergonomic front-open machine design guarantees unrestricted operator access and direct chip flow, while independent synchronous spindles tailor cutting speeds at every station.
- 6 or 8 independent motor spindles accommodating bar diameters of 24 mm or 40 mm
- Front-open working area configuration providing ergonomic access and free chip flow
- High-dynamic slide assemblies with rigid X-axis guideways and rapid clamping
- Spindle carrier drums, hydraulic distribution blocks, and bar feed collet chucks
TRAUB TNL12 and TNL20 Swiss-Type Sliding Headstock Lathes
TRAUB TNL12 and TNL20 Swiss-type sliding headstock automatics produce long, slender components for medical and electronic assemblies. The modular design switches rapidly between sliding and fixed headstock modes, while independent turrets allow simultaneous cutting with up to four tools.
- Convertible between sliding and fixed headstock operation within minutes
- Simultaneous multi-tool machining with up to 4 tools and Y-axis on all tool slides
- Rapid CNC turret indexing cycles eliminating non-productive auxiliary downtime
- Guide bush collet assemblies, bar feed clamping stations, and tool drive couplings
TRAUB TNA400 and TNA500 Universal CNC Turning Machines
TRAUB TNA400 and TNA500 universal CNC lathes are engineered for chuck and bar work on workpieces requiring high cutting rigidity. The slant-bed structure facilitates direct chip flow during heavy roughing, while the conversational TX8i-s control system monitors real-time cutting tool loads.
- Turning diameter over bed up to 500 mm with turning length capacity up to 1000 mm
- High-torque spindle drive motor delivering reliable heavy roughing and fine finishing
- 12-station tool turret with direct VDI mounting and driven milling tool attachments
- Spindle brake disc assemblies, Z-axis ball screws, and reference mark encoders
INDEX Spindles, Turrets, Hydraulics, and iXpanel Controls
The factory assembly catalog covers synchronized motor spindles, hybrid bearings, VDI live turrets, Rexroth hydraulic manifolds, and iXpanel CNC interfaces. Supplying factory-grade modules restores baseline tolerances and machine reliability across the entire INDEX and TRAUB equipment fleet.
- Dynamically balanced main and counter motor spindles with integrated cooling
- Hirth coupling rings and precision servo indexing drives for tool turrets
- Rexroth hydraulic directional valves, Vogel lube pumps, and 80-bar coolant valves
- Sinamics S120 drive power modules, Siemens ONE CNC units, and iXpanel operator terminals
Technological Advantages and Structural Rigidity of INDEX and TRAUB Machines
The German machine tool manufacturer INDEX Group, operating under the INDEX and TRAUB brands, leads global precision turning technology with advanced kinematics and superior machine bed dampening.
Incorporating heavy mineral cast beds and proprietary SingleSlide guideway dampening, these machines eliminate dynamic vibration during high-feed milling and hard turning of tough alloys.
Advanced CNC platforms, including Siemens Sinumerik with INDEX iXpanel Industry 4.0 cockpit and TRAUB TX8i-s control, offer integrated cutting force monitoring, real-time thermal growth compensation, and seamless network connectivity for automated multi-shift factory operations.
Engineering Selection Guide by Part Complexity, Kinematics, and Batch Volume
Selecting the appropriate INDEX or TRAUB machine depends on workpiece geometry and production lot size: high-speed bar turn parts are optimized on INDEX C100/C200 lathes; mass turned components with cycle times in seconds run on INDEX MS multi-spindle automatics; while slender medical parts demand TRAUB TNL Swiss-type turning machines.
Simultaneous 5-axis capability on INDEX G200 and G220 turn-mill centers allows manufacturers to consolidate separate turning and milling operations into a single continuous cycle, drastically reducing work-in-progress inventory, shopfloor footprint, and secondary clamping setups.
Motorized Spindles, Hirth Turret Couplings, and Automation Integration
INDEX synchronous motorized spindles combine high torque output across low RPM ranges for heavy-duty roughing with fast speed performance for fine end-milling.
Tool turrets with precision ground Hirth coupling rings deliver rigid mechanical lock and micro-radian repeat positioning under heavy radial loads.
Integrated automation modules include high-capacity automatic bar loaders, robotic workpart pickup gantries, and high-pressure coolant circulation systems delivering up to 80 bar fluid directly through the cutting tool edge for optimal chip breaking.
