X-5 VMC Can Perform 5-Axis Simultaneous Machining

The Dugard Eagle X-5 vertical machining centre (VMC) will demonstrate simultaneous five-axis tool positioning at MACH 2008 and combine multiple operations, incorporating up to five sides of a component into a single cycle. As a result, high levels of geometric relationship between different features of a component are maintained and, by combining operations, shorter production lead times.

The Dugard Eagle X-5, five-axis VMC is controlled by the high specification Heidenhain iTNC 530 control and in a typical C Dugard specification, there is a choice of options to suit different machining scenarios and customer needs. For instance, while the standard spindle is 10,000 revs/min via a belt drive, this high productivity VMC has also been developed to accommodate high speed 18,000 and 24,000 revs/min units.

The fully supported combined saddle and table casting sits on an exceptionally rigid bed casting to provide maximum stability to the direct mounted, trunnion style rotary and tilt table. This enables the two-axis unit to accept loads up to 600 Kg and has high torque linear technology drive motors integrated within the rotary and tilting axes.

Travels are 500 mm in X, 600 mm in Y and 465 mm in Z while the A-axis can be tilted between +95^o to –95^o. The fully programmable 360^o C-axis can be positioned or rotated at up to 100 revs/min to accommodate light turning applications integrated with five-axis milling and drilling cycles. Rapid traverse rates are 40 m/min in each axis to an accuracy of + 0.005 mm and repeatability is within five microns.

A 24 position, electrically driven tool magazine with a cam-type swinging arm enables tools to be exchanged in just 2.5 secs. All three spindle variants have the advantage of HSK 63A tapers.

With two higher specification CyTec electro-spindles available in addition to the 10,000 revs/min standard fitment, the 18,000 revs/min unit is powered by a 27 kW drive developing 129 Nm of torque. Meanwhile, the optional high speed 24,000 revs/min unit is powered by a 43 kW motor having 91 Nm of torque for heavier duty machining cycles.

For five-axis linear interpolation, the Heidenhain iTNC 530 control is hard to beat for specification, features, operator interface and full 3-D, five-axis simulation. Program memory is ample at 30 GB and a whole range of canned cycles is included. Helical and spline interpolation are also included with Dynamic Collision Monitoring available as an option.
