Multi-spindle turning on display

Tornos will give a UK exhibition debut to the MultiSwiss 8×26 (hall 19, stand 312). The machine is one of a family of three that range in spindle size from 14 to 32 mm. Equipped with eight spindles and eight slides for main operations, and accommodating up to three tools per slide, the MultiSwiss 8×26 features eight synchronous motor spindles and fast barrel indexing for producing turned parts up to 26 mm in diameter. Each of the 11 kW motor spindles is equipped with a C axis and counter spindle.

The counter spindle is mounted on two axes so it can work completely independently. Offering up to five tool positions, two of these provide the option of driven tools. A quick-change tool-holder system developed for MultiSwiss machines makes full use of kinematics that focus on keeping tools close to the workpiece, maximising in-cut time. Thanks to the damping performance when machining, Tornos says that the MultiSwiss can improve surface finish and extend tool life by an average of 30%, and up to 70% in some cases.
