Originally unveiled at EMO, last September, in Hanover, Germany, the EvoDeco 32 machine will be making its UK appearance at MACH 2014.
The 32 mm bar diameter machine is said to have "a remarkable design that boasts surprising power both for spindle and counter-spindle machining". To underline its capabilities, a typical component -machined from 303 stainless steel – will be highlighted at MACH.
Machined from a 32 mm diameter bar, the machine must drill a 150 mm deep hole into the stainless steel part, but also reduce the outer diameter from 32 mm to 22mm over a length of 90 mm. Tapping, flat milling and drilling are all part of the process. "The part is not dissimilar to something made by our customers; it is subject to very stringent controls, in terms of dimensions. Furthermore, we wanted to adhere to market requirements for our test conditions. To this end, we have worked at speed with exceptional precision", says Arnaud Lienhart, EvoDeco 32 project manager at Tornos.
The part is finished in 130 seconds, with a competitor machine demonstrating almost 40% lower productivity, says Tornos.
The spindle motorisation has "been pushed to the limit", with the machine generating a maximum power of 12.8 kW and a torque of 20.4 Nm. The power is the same in the main spindle as in the sub-spindle, with this making it the most powerful lathe in its category, Tornos claims.
The kinematics allow four tools to be engaged in the material simultaneously, with Tornos employing platen versus competitors' use of turret. While turrets provide a wealth of tools, plattens are designed for speed and productivity, the company explains.
Says Mr Lienhart: "To get an idea of the power of the EvoDeco 32, I would recommend that you watch the part being machined on the YouTube platform [shown above]. For the purposes of the film, the part is made from brass, but our specialists would welcome the opportunity to demonstrate the power of the EvoDECO 32 to you on harder materials".
