Mills CNC, the exclusive distributor of Doosan machine tools in the UK and Ireland, has entered into a collaborative research partnership with Irish Manufacturing Research (IMR), an independent, not-for-profit research and training organisation (RTO) based in Mullingar, County Westmeath. To support the organisation’s research programme in the Irish market, Mills supplied IMR with a new Doosan Puma 2600SY II lathe in August 2020.

The 10“ chuck box-guideway multi-tasking lathe features a 22 kW/4000 rpm spindle, a Y axis (±52.5 mm), a sub-spindle (15 kW/6000 rpm) and driven tooling capabilities (7.5 kW/5000 rpm). Furthermore, the model supplied to IMR featured a number of ancillary technology additions to increase its productivity and efficiency, including: a Hydrafeed servo-driven bar feeder; Filtermist oil/mist extraction unit; Renishaw optical workpiece inspection probe; LNS swarf conveyor system; FSE filtration system; and Hainbuch collet chucks.

The lathe also features an automatic door and a robot interface to facilitate automated workpiece loading/unloading in the future.

Although the Puma was only installed a few weeks ago it has already been involved in a number of customer-led projects. One of these involved exploiting the lathe’s multi-tasking capabilities – using the Puma lathe’s Y-axis, mill-drill and capabilities to significantly reduce the number of machining operations, cut cycle times and conduct in-process inspection to improve part quality.

The project has demonstrated that the Puma lathe’s on-board technologies (including its thermal compensation capabilities) can significantly reduce component processing times – from five down to just one operation – and increase part accuracies.
