MP Engineering has utilised a Deckel Maho DMU eVo linear vertical machining centre to help it supply parts to the aerospace sector and Formula 1.

The use of indexing tables on three-axis vertical machining centres has enabled the company to produce a range of workpieces for motor sport giants, from body styling parts through to engine components.

The Deckel Maho DMU has a 40 rev/min B-axis for machining angles up to -18 degrees, combined with a linear drive in the X-axis that produces high speed traverse rates up to 80m/min (complemented by 50 m/min in both Y and Z axes).

The 18,000 rev/min spindle, supported by a double-gripper for fast and reliable tool change time (chip-to-chip time is just five seconds) further boosts productivity.

It has a working envelope of 500 x 450 x 400mm.

MP invested in the DMU because it was supplied as standard with a Heidenhain control system and because its compact footprint (2.9 x 3.5m) meant it didn’t take up too much floorspace.

The machine’s working envelope allows it to cope with most workpiece size expectations.

Jason Poole, director of MP Engineering, said: ‘The Heidenhain iTNC 530 CNC is fantastic for 3D contouring, for example, which is critical for a lot of the work we handle.’ He also said the machine’s BT40 spindle meant all his existing back-end systems could be used.

The CTX 310 has driven tools in each of its 12 stations, plus Y-axis for single set-up off-centre boring and milling tasks, allowing it to handle bars up to 51mm diameter, with a swing of 505mm and cross (X axis) and vertical (Y) travels of 213mm and + 40mm.

Complementary rapid traverse rates in X-, Y- and Z-axes are 24m/min, 10m/min and 30m/min, respectively, and linear guideways and digital drives also add to the high performance.

Commenting on the machine’s Siemens 840D control technology, Poole said: ‘Its Shopturn functionality is proving excellent for complex undercuts and grooves.

‘We simply input tool geometry and the control does the rest and, as a result, the machine gives us more than everything we need in terms of one-hit turn-mill capability.’
