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...

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...

S11 Y4 S41 Z1 S11 C1 S1 X1 Double cone collet for headstock. C4 S4 Rotating milling or drilling attachment, with spindle for ESX-25. Motorized end working tool block for up to 4 rotating or steady tools. SIGMA 20 / SIGMA 32 End working tool block with 7 positions, Ø 20 mm bores, for steady 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...

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...

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.
