New 5-axis workhorse is flexible and built to last

Available in the UK from GM CNC, the Vcenter AX630 is highly flexible, incorporating a B- and C-axis rotary table to facilitate the 5-axis machining of large parts up to 700mm diameter by 500mm.

The AX630 has rigidity and precision incorporated into every aspect of its construction, characterised by the trunnion type B- and C-axis table that has a built-in backlash-free roller cam mechanism seated on the machine base to maximise rigidity.

The B-axis can rotate at up to 17rpm with 6,880Nm of torque whereas the C-axis rotation is capable of 33rpm at 1,960Nm. Adding to the integrated robust and rapid rotary table, the AX630 optimises structure stiffness with the moving column and spindle retaining an optimised centre of gravity. The spindle is fully supported by front slideways when the Y-axis travel is shorter than 300mm which ensures optimal cutting performance during the most challenging of operations.

The 9,000kg workhorse is supplied as standard with the powerful Fanuc 0i-MF CNC unit that drives the tools around the 700 x 500 x 500mm (XYZ) work envelope with high precision and speed. In addition, a high-speed 12,000rpm spindle with Big Plus BBT-40 interface maximises tool clamping rigidity.

Powering the rapid spindle is a continuous 11/15/18.5kW spindle motor that generates impressive levels of torque for the heavy-duty cutting of challenging materials at high material removal rates. The stable machine platform promotes excellent surface finishes.

The spindles are manufactured in-house by Victor and each has a unique ID code to facilitate future servicing requirements and records. Supplied with up to 30 tools via a twin-arm type fast-change tool barrel, customers can also select the machine with the option of 40, 48 or 60 tool positions.

As standard, the high-quality arrival incorporates a spindle oil cooler, fully enclosed splashguard, rigid tapping facility, remote MPG handwheel, hand tools and toolbox, built-in work light, auto power-off system, levelling pads and a screw-type chip removal system.

On the flexibility front, the Vcenter AX630 provides the option of a chip conveyor with cart, through spindle coolant from 20 to 70 bar, linear scales/angular encoders for precision levels of 0.005mm over the full machine stroke, auto-tool length measurement, auto-part measurement, HSK-A63 interface and also a selection of control units that include the Fanuc 0i, 32i and the 31i control or the Heidenhain 640.

For full simultaneous 5-axis machining, the machine is now also available with the Fanuc 31i-B5, the Siemens 840D or the Heidenhain TNC-640 CNC interface. This extensive array of optional additions allows GM CNC to facilitate all machining requirements, making it well-suited to manufacturers that demand a blend of high productivity levels and flexibility with the guarantee that the machine tool is built to last.
