It is the high flexibility generated through the four-axis, 16 tool all-driven turret of the latest Maier ML ProLine 32E CNC sliding head auto that enables a combination of complex three-dimensional forms to be milled and, through a fully programmable 0.01deg angle positioning axis, precise in-cycle machining from the turret of angled internal and external features and holes. Now available through StarragHeckert UK of Brackley, the 12-axis Fanuc 160iT CNC, all servo-controlled machine is targeted at more complex part machining requirements such as those found in medical implants, telecomms, hydraulic and fuel injection type applications and often required in difficult to machine high tensile materials. Mounted upon a polymer composite base with the highest levels of thermal stability, rigidity and therefore minimal effects of vibration, three totally independent carriages enable up to three tools to be engaged on a workpiece at the same time.

The construction also supports high feed rates up to 32m/min reached with an acceleration to full speed within 1mm of travel and enables idle times to be minimised thus maintaining full use of the highly flexible tooling arrangement without any loss of productivity.

The sliding head mill/turn centre combines two-axis main and three-axis secondary spindles with an octagonal turret having 16 all-driven positions with tools mounted side by side and positioned via an X-axis cross feed.

Altogether, there are 36 tool positions of which 26 can be driven by 1.5kW motors to provide a wide option of tooling arrangements to satisfy high productive 'one-hit' cycles.

The main and opposed spindles both have C-axis positioning with 5.5kW, 6,000 rev/min drive and a stroke of 220mm for the main Z1 and 230mm of travel for the opposed Z2 spindle.

Surrounding the main spindle is an X-Y tool carrier able to hold four powered cross-machining tools and six turning tools.

The three-axis back working attachment, which has its own Y-axis feed, is able to position three static and six live tools arranged in a grid fashion that maximises setting flexibility and creates short tool movements to engage with the workpiece.

A fully programmable 120 bar high pressure coolant system is optional to the standard system along with quick-change tool holding system.

Specialised cycles such as thread whirling, polygon turning and forming, right angle and adjustable angle drilling/milling units are also available along with part support and separation for machining long components.
