Tornos’ new Swiss ST26 to get MACH debut

Added to MTDCNC by Tornos Technologies UK Ltd on 18 January 2014

Making its UK exhibition debut at MACH 2014 on Stand 5260 will be the new Tornos Swiss ST26. Initially developed as a simple machine covering a wide range of requirements for the Asian and American markets, the success of the ST26 will see a CE version for the European market, launched at MACH..

Equipped with 7 linear axes and 2 C axes, the new ST26 will be positioned as a direct competitor to machines equipped with 5 or 6-axes, but in the same price range. It completes Tornos mid-range offering, sitting between the EvoDeco, a flexible solution with excellent production capabilities and the Gamma, a machine with proven performance for machining moderately complex workpieces.

The ST26 has the capacity for workpiece diameters to 25.4mm and lengths of 220mm that is encased in a 2300 by 1300 by 1700mm (length x width x height) footprint. With a weight of 3300kg and a spindle and counter spindle power of 9.5kW, the new ST26 offers all the precision and rigidity a customer could require.

With the first machines already delivered, the company decided to find out what customers thought of the new ST26. They are all impressed by two things in particular: the kinematics that offer two independent plattens, the rear of which can work on the bar and perform back operations. This enables several machining operations to be executed concurrently. The other factor of note is the identical operation and back operation spindles, which are both powerful and highly responsive. The combination of these two components enables a balanced setup between the two sides of the workpiece being machined. It also supports the production of relatively complex workpieces on such a ‘simple’ machine. Three tools can be engaged in the material simultaneously. Back operations are performed simultaneously with either platten 1 or 2, allowing work to continue on the guide bush.

Completely developed and produced in Switzerland, the synchronous type spindle delivers 9.5kW as well as super-fast acceleration and deceleration from 0 to 10,000rpm in 0.9 seconds. It is by far the most powerful and responsive machine on the market in this product category. Equipped with an integrated cooling system, the spindles contribute to the machine's thermal stability to deliver increased precision.

Equipped with a variety of tool systems, the machine can take up to 42 tools, including 16 rotating tools. Numerous devices are available for specific operations, such as polygon operations, thread-whirling processes and milling. The Swiss ST 26 is offered as standard in three versions. The starter, the advanced and Medtech. These three packs include a variety of equipment suited to the type of workpieces to be produced. Depending on the requirements, the company can also supply additional equipment such as chip conveyor, high pressure pump or oil mist extractor.
