INTRA 520 CN2 / INTRA 520 XL CN2 5-Axis CNC Bridge Cutting Machine

The Intra blends the ease of use of a traditional manual machine, with the high output operator free sawing cycles. Simple and intuitive programming enables owners and operators to get the most from the machine - featuring parametric drawings, Cuts From CAD, Contouring, Bas relief, profiling and shaping, drilling and lettering, the machine can also be equipped (upon request) with a digital camera to provide a jpeg of the slab on screen, automatic movement/unloading of sawn pieces saving time, man power, and raw material by using integrated Vacuum head, auto tool changing with either ISO40 or simple magnetic connection, overlapping automatic table changing, a rodding device to create grooves in the underside of pieces, and even a lathe (gearbox driven or CNC).
Fully interpolated 5 axis movement with rotating head with 370° range, inclination from 0°-90°.
Hot dipped galvanized steel fi xed with saw surface in high density plastic rubber matting (optional) with max blade size of 725 mm (28.5 in) with Z axis (rise and fall movement) - 400 mm (15.75 in).
The complete structure is made up of hot dipped galvanized steel structures - supplied with folding door solid panel safety barriers.
Fast and precise movements due to brushless motors with absolute encoders, recirculating ball bearing movement, precision gearboxes and interpolated axis controlled by CNC.
Electro spindle running up to 4300 rpm (6000 on request) with centre waterfeed and a 36x2 or ½ gas fitting. Or (on request) ISO40 cone fitting running at up to 8000 rpm for automatic tool changer (on request).
Suspended pendant with 15” TFT color touchscreen. Machine is equipped with USB/Ethernet port for easy loading of programs. Stainless steel electrical panel.
