Overview

The INDEX-Traub TB65 is a large-capacity CNC Swiss-type lathe handling bar stock up to 65 mm in diameter, bridging the gap between standard Swiss-type lathes and full-size CNC turning centers. The TB65 applies the Swiss sliding-headstock principle to medium-to-large bar diameters where conventional Swiss-type machines top out, making it particularly valuable for long slender shaft work in the 30–65 mm diameter range that exceeds the capacity of smaller Swiss machines but benefits from guide bushing support that conventional lathes cannot provide.

At 65 mm bar capacity, the TB65 opens Swiss-type production to hydraulic cylinder rods, long spindle shafts, valve stems, and industrial fasteners in the 40–65 mm range—components with length-to-diameter ratios that cause deflection and chatter on conventional turning centers without steady rest support. The guide bushing positions support at the cutting zone regardless of part length, enabling aggressive cuts and tight tolerances on challenging long workpieces.

The TB65 features a high-torque main spindle capable of handling the larger-diameter materials typical in this size class, with servo-driven headstock motion for precise Z-axis control. Live tooling positions enable cross-drilling, milling, and threading operations perpendicular to the bar axis, and a backworking attachment completes the parted face without secondary operations. The Siemens or Fanuc CNC control (depending on market specification) provides the programming environment with Swiss-specific canned cycles.

For manufacturers of hydraulic components, pneumatic cylinders, precision shafting, and industrial fasteners who need the accuracy of Swiss-type production on larger-diameter bar work, the TB65 fills a genuine market gap that neither conventional Swiss lathes nor standard turning centers address as effectively. Its combination of guide bushing precision and 65 mm capacity makes it unique in the INDEX-Traub lineup.

Best For

Hydraulic system manufacturers producing cylinder rods, valve stems, and precision shafting in the 30–65mm bar range requiring tight straightness tolerances Aerospace and defense manufacturers producing long slender shaft components in titanium and specialty alloys where guide bushing support is critical for tolerance compliance Industrial fastener manufacturers producing large-diameter precision studs, bolts, and threaded rods where turned length greatly exceeds diameter Oil and gas equipment manufacturers producing precision valve components, actuator shafts, and instrumentation components in medium-large diameters

Frequently Asked Questions

01 What makes the TB65 different from a conventional CNC turning center with a steady rest?

The TB65's guide bushing supports the workpiece at the cutting point, eliminating deflection along the entire length of the part—not just at one or two steady rest positions. For long slender parts, this provides fundamentally better dimensional control and surface finish than a steady rest on a conventional lathe, particularly for tight-tolerance bore and OD concentricity requirements.

02 What is the maximum bar capacity of the INDEX-Traub TB65?

The TB65 handles bar stock up to 65mm (2.56 inches) in diameter—the largest Swiss-type bar capacity in the INDEX-Traub lineup. This makes it suitable for hydraulic rods, shafts, and valve bodies in the 30–65mm range that exceed standard Swiss machine capacity.

03 Does the TB65 support automation?

Yes. The TB65 integrates with bar feeders for continuous bar production—the standard automation approach for Swiss-type lathes. At 65mm bar capacity, magazine bar feeders with appropriate diameter capacity are used. INDEX-Traub offers compatible bar feed interfaces and works with major bar feeder manufacturers.

04 What control does the TB65 use?

The TB65 is available with Siemens 840D sl or Fanuc 32i-B control depending on market and customer specification. Both controls support multi-channel simultaneous machining with Swiss-specific programming cycles. Shops already invested in either control platform can specify their preferred option.

05 How does the TB65 compare to larger turning centers for the same size range?

For parts with length-to-diameter ratios above approximately 4:1 in the 30–65mm range, the TB65's guide bushing support delivers better tolerances and surface finish than conventional turning centers. For shorter chucked parts or parts with ratios below 4:1, a standard turning center like the INDEX G300 or G400 is a better fit and provides more chuck work flexibility.
