A next-generation CNC system featuring a touch-screen and a qwerty keyboard will be a key feature on the new Cincom D25-VIII and -VII sliding head-stock turn-mill centre (Hall 20 Stand 570).

Displayed on the MACH stand of Bushey-based Citizen Machinery UK Ltd, this system maximises the machine’s operational flexibility for complex cycles (www.citizenmachinery.co.uk).

The Cincom D25-VIII is configured as a 10-axis sliding-head machine with a 25mm-diameter capacity.

It incorporates a swivelling B axis (0-135deg) within the first gang tool post (X1, Y1 and Z1 axes), which can hold four double-sided driven spindles and access both the main spindle and the sub-spindle.

A second gang tool post (X2, Y2, Z2) can work independently or simultaneously with the first tool post to overlap rough- or finish-turning operations, for instance, or apply drilling- or milling-based cycles in unison.

Meanwhile, further machining flexibility is provided by a (Y3) back tool post with one fixed or three driven tools offering 90deg adjustment for face, radial or angle machining; there is also an ‘opposite’ tool post alongside the sub-spindle (X3, Z3), which provides a further two fixed-tool positions.

There is an overall capacity for up to 59 tools. The machine also offers the advantage of removable guide bush for more-economic material use on shorter components.

The power of the main spindle is 5.5kW, with 3.7kW available for the 25mm-capacity sub-spindle; both offer a maximum speed of 10,000rev/min.

The gang-driven tools are powered by 2.2kW drives with maximum speeds of 9,000rev/min, while the back driven-tool speeds are 6,000rev/min.

Rapid-traverse rates are 32m/min, with 24m/min available on the Z2 gang tool post.
