THINK PARTS THINK TORNOS SIGMA 20 / SIGMA 32 Sliding headstock single spindle automatic lathe

SIGMA 20 / SIGMA 32 IN A FEW WORDS! The only Swiss type sliding headstock machine being able to produce parts using the machining parameters of a fixed headstock machine. Simplicity ■ Mirror image kinematic. ■ Setting, adjustments 100% numerical. ■ 2 independent tool slides with fully compatible and interchangeable tooling. Performance ■ High productivity. ■ Identical headstock and counter spindle. ■ Independent roughing tool. ■ High power for high depth of cuts and large chip removal. Rigidity ■ Identical heavy duty machine construction, for main and counter operations. ■ Capable of machining...

SIGMA 20 / SIGMA 32 A KINEMATIC GEARED TOWARD MULTI TASKING AND PERFORMANCE! Multi tasking ■ All the tool holders and accessories can be mounted on either tool slides. ■ Large array of heavy duty tool holders, allow for the machining of value added operations. ■ Up to 28 tool positions. 4 Performance Great capacity for chip removal. ■ Thanks to a roughing tool, it is possible to have up to 3 tools in the cut simultaneously. ■ SIGMA 20 / SIGMA 32

When the SIGMA 20 / 32 is coupled with the Tornos bar loader SBF 532 it forms a high performing and complete manufacturing cell from a single source supplier. Rigidity ■ SIGMA 20 / 32 is the only lathe on the market that offers an identical rigidity in main and counter operations. ■ Identical headstock and counter spindle offer high power (6.0 / 7.5KW). SIGMA 20 / SIGMA 32 Simplicity Programming choice, ISO or TB-DECO (option). ■ Very simple ISO programming, thanks to the 2 channels concept which are completely independent. ■ Excellent ergonomics permitting to easily change and set the tools...

Roughing tool, activated by M codes. (SIGMA 32 only). 9

SIGMA 20 / SIGMA 32 SIMPLICITY: THE GUARANTEE OF USER-FRIENDLY OPERATION! The new Tornos innovations coupled with tried and tested solutions will very quickly enable the operator to successfully use the Sigma 20 & Sigma 32. ■ ■ 10 ISO programming and TB-DECO as an option. ■ Very easy programming in ISO language thanks to the kinematic concept that uses two completely independent tool systems. TORNOS macro assistant simplifies cutting, bar feeding and bar end operations. ■ Entirely numeric tool setting and adjustment (all tools are fitted on 3 axes with no mechanical adjustments). ■ ■ Rapid tool...

SIGMA 20 / SIGMA 32 RIGIDITY: THE GUARANTEE OF QUALITY MACHINING ■ In counter operations with as much as 3x the rigidity than its competitors the SIGMA 20 / SIGMA 32 allows for a profitability as much as 30% higher for parts where the machining operations are well balanced between main and counter operations. ■ Identical rigidity and identical spindles in main and counter operations. ■ The tool wear and the machining quality are directly linked to the machine rigidity. On the SIGMA 20 / 32, it is no longer necessary to favor the machining operations to the work done in main operations so to optimize...

SIGMA 20 / SIGMA 32 PERFOMANCE: THE GUARANTEE OF OPTIMUM PRODUCTIVITY ■ ■ 12 All machining operations, such as turning, radial drilling and milling and axial drilling can be executed as back-operations. ■ Inox 303 Ø 20 mm SIGMA 20 and SIGMA 32 have identical power and rigidity in main and counter operations. ■ 42 CR MO S4 Ø 22 mm The spindles offer a high clamping force. If needed it is also possible to mount a double cone collet on the headstock as well as a large opening (for over clamping) collet in counter operations. ■ AC.
