Tornos back at EMO in full force
EMO Hanover is the unmissable event for all European machine tool manufacturers. This is why Tornos chose it as the arena to unveil no fewer than 5 world premieres, along with two new completely revolutionary product ranges, namely the MultiSwiss 6x14 and Cyklos lines. During the 2009 economic crisis, the Tornos group implemented a short-time working policy in order to save jobs. All departments were affected with the exception of one: the "research and development" group. The Tornos group is proud to be able to demonstrate the results of this policy today.
World premiere No. 1: Sigma 32/6
The machines in the Sigma range are well-known for their power and rigidity; they are the only sliding headstock machines on the market able to work with the machining parameters of a fixed headstock machine. To increase their target market, the two Sigma models have benefited from a range of new features which allows them to be even more finely adapted to the requirements of the market. "The first thing to strike customers who have just purchased a Sigma turning machine is the quality of the workpiece created by the machine, even at high feedrates; identical rigidity of the machine in main and secondary operations means that impeccable surface finishes are created", explains Arnaud Lienhart, Sigma Product Engineer at Tornos. As the power of the 32mm (6.0/7.5 kW) model's spindles is identical in both main and secondary operation, swarf removal is beyond compare. According to Arnaud Lienhart, with a well-adapted peripheral, it is virtually impossible to stall a spindle or counter spindle on a SIGMA 32/6 turning machine. Thanks to the mirrored kinematics, identical spindle power and comparable rigidity on the two stations, it is no longer necessary to favour operations on the bar.
World premiere No. 2: Delta 38/5
The Moutier-based group's partnership with the Japanese Precision Tsugami group has enabled it to develop the Delta 38/5 machine - its passport to the world of large diameters. Produced by Tsugami to Tornos' own specifications, this turning machine offers great rigidity and high power. The Swiss engineers were involved in developing the Delta 38/5 turning machine. The partnership brought together two different visions to produce the optimal machine; in addition, like similar partnerships in the automotive industries, the Delta 38/5 retains the Tornos-specific features, particularly in terms of the software, with a complete range of G900-type programming help macros. Now, Tornos has the most extensive range of products in the world when it comes to automatic turning machines with sliding headstock.
World premiere No. 3: MultiSwiss 6x14
A numerically-controlled multispindle turning machine featuring new technologies and containing all the peripherals required for optimal operation, at a lower price than any other CNC multispindle machines: that's the achievement of the MultiSwiss 6x14. It takes its name from the maximum bar passage diameter (14mm) multiplied by the number of spindles. The user-friendly MultiSwiss has been designed to offer maximum user comfort. We can confidently affirm that it is the most comfortable multispindle turning machine currently available: The MultiSwiss is the first frontal machine available on the market. It is also the first machine not to use Hirth gearing to lock the barrel. This classic system, well-known to Tornos, has been successfully replaced with a torque motor. The spindles are equipped with a hydrostatic sheath to guarantee excellent damping. In addition, the MultiSwiss 6x14 is the first multispindle turning machine on the market to be equipped with mobile spindles. That makes it the first sliding headstock multispindle turning machine to offer an all-in-one peripheral concept. (see www. multiswiss.info) The MultiSwiss is the new jewel of the Tornos range; it will produce jewellery using multiprograms to demonstrate how easy the MultiSwiss is to use, and offers productivity equivalent to that of a cam-controlled multispindle turning machine.
World premiere No. 4: Almac CU1007
The Almac CU1007 machining centre will be presented with its softening cell; it enables parts to be fully machined. This means that the front and rear faces are machined on a single machine. The robot at the centre of the assembly enables the part to be loaded and transferred between machines, and also manages the palletisation and softening of the part. The machining centre will be used to produce a brand new medical part.
World premiere No. 5: Cyklos
Cyklos will be the first of a new kind of surface treatment machine. The Cyklos is the first surface treatment machine that can be installed in a standard mechanical workshop. Unlike a traditional process, which works using vertical immersion, the Cyklos works by rotating, thus guaranteeing superior quality. The Cyklos technology will be presented alongside the MultiSigma 8x28 Chucker machine. This machining solution allows Tornos to establish itself as a supplier of genuine solutions. This new concept allows our customers to make serious steps forward in how they organise the treatment of their large-volume parts. With Cyklos and MultiSigma, Tornos is offering a real lean manufacturing solution.
