The Tornos family is now expanding with the introduction of the new Swiss GT 13 machine


The engineers at Tornos have worked tirelessly to develop a new machine concept that more than satisfies the customers’ low capital cost and high performance demands. Targeted at the precision production of medium to highly complex parts up to 13mm diameter, the Swiss GT 13 is the ideal machine tool for the medical, micro-mechanical and electronics sectors. You can do almost everything a complex machine could do, but with a much more interesting price/performance ratio. The ingenious kinematics and tooling configuration allow the machine to tackle almost every turned part on the market efficiently.

In brief, the new Swiss GT 13 incorporates a counter-operations post with a Y-axis featuring 8 tool positions that can work independently. With identical power ratings on both spindles and a total of 30 tool positions, the Swiss GT 13 has 22 tool positions on the main platen and 8 in counter-operation, 12 of these positions can be rotating tools. The back tool stations of the main platen can be equipped with specialist devices such as angled milling devices, polygon milling, thread whirling, gear hobbing and frontal dual drilling tools to name a few. By combining this capability with the 6-axis kinematics, the Swiss GT 13 is able to tackle almost every conceivable turned part..

This impressive new addition to the Tornos line has been equipped with a brand new 15,000 rpm spindle that features the company’s brand new motorized guide-bush design. The convertible guide-bushless configuration now sees the guide-bush simply sit in a special support in the spindle area when it is not required. The result is a changeover time of less than 15 minutes. For competitor machines, the guide bush has to be disconnected and this is a process that prolongs set-up and job changeover times considerably for the customer. This motorized guide-bush design also allows the machine to run at maximum rpm whilst increasing the precision and surface finish of parts whilst reducing the vibration and the consequent impact on tool life.

With the same spindle rating on both the main and counter-operation spindles, customers have greater flexibility and productivity at their finger-tips, so there is no need to balance more demanding operations toward the main spindle any longer. To manage all this power, the Tornos engineers have optimized the size of the machine base to guarantee stability and performance. Despite its high performance, the Swiss GT 13 has a very compact layout that is well presented with Tornos intuitive Tornos Machine Interface (TMI) that can be programmed as a numerical control unit or via Tornos’ own TISIS software to enhance user friendliness.
