Used Index CNC Lathes for Sale 84

Index-Traub has consolidated the German engineering heritage of both Index (multi-spindle automatics) and Traub (Swiss-type sliding headstock lathes) into a product range that covers the most demanding tiers of CNC production turning. Machines from both heritage lines continue in production, addressing different applications in high-volume precision turned parts manufacturing.

The Traub TNL series sliding headstock Swiss-type CNC lathes handle bar capacities from 8mm to 38mm, covering the precision turning range from watch components and medical implants through electronic connectors and automotive fasteners. Multi-axis configurations with live tooling, sub-spindles, and Y-axis capability enable complete part production from bar stock. The mechanical precision of Traub machines is widely recognised — sliding headstock accuracy, guide bushing precision, and overall thermal stability set benchmarks that competitors chase.

The Index C and G series CNC multi-spindle machines represent Index's evolution from cam-operated multi-spindle automatics to full CNC-controlled multi-spindle production. The C100, C200, and G200 platforms machine 4, 6, or 8 parts simultaneously through CNC-programmed spindle stations, combining the traditional multi-spindle productivity advantage with the flexibility of electronic programming. Changeover times dropped from days on cam-operated machines to hours on CNC versions, opening multi-spindle production economics to smaller batch sizes.

The ABC series horizontal turning centres complement the Swiss-type and multi-spindle specialties with conventional chuck and bar-fed turning capability, rounding out the Index-Traub product range for general precision turning.

Control systems combine the proprietary Virtuos programming software with underlying Siemens or Fanuc CNC platforms depending on the specific machine. The Virtuos layer provides simulation, offline programming, and cycle time optimisation that simplify the complex programming that multi-spindle and multi-axis Swiss-type production requires.

German manufacturing origin and premium positioning mean Index-Traub machines command premium pricing on both new and used markets. The capability justifies the investment in applications where production volumes and part complexity require the productivity that only these platforms deliver.

When evaluating used Index CNC lathes on Exapro, request spindle accuracy measurements and thermal stability test data, verify guide bushing condition on TNL machines, test all spindle indexing and live tool positions on multi-spindle machines, and confirm CNC control software version and programming capability. Comprehensive service documentation is particularly valuable on these complex, high-value machines.
