CONTOURBRETON NC 300 EVO 4-axes CNC machining center

WITH A PRESTIGIOUS PAST

The new Contourbreton NC 300 EVO comes from the experience of the previous Contourbreton models, countless examples of which have been sold worldwide with great success.

WIDE TRAVELS, SAFETY & ACCESSIBILITY

Wide working travel of 3,200/3,800 mm in “X” axis, 1,950/2,300/4,000mm in “Y” and 300 mm in “Z” (vertical axis).

The NC 300 EVO’s comes with manually opening doors with safety interlock switches.

The work table is made from a single piece of a special quartz-based polymeric material, Metalquartz®.

Large doors and lower work table with integrated step offer the best front access ergonomics in the industry.

The strong electro-welded structure ensures the rigidity needed for any kind of machining.

DRIVEN BY SIEMENS BRUSHLESS MOTORS

Racks & pinions systems and Siemens brushless motors drive the mobile bridge and the spindle unit.

A gantry system drives the mobile bridge. Linear guides

with recirculating balls and precision encoders assure the movement accuracy.

WORK TABLE IN METALQUARTZ ®

Continuous work table made of Metalquartz®, a special

patented quartz-based composite material with a polymeric matrix, specially engineered to ensure the same high rigidity and expansion coefficient as steel.

HIGH PERFORMANCE VACUUMING SYSTEM

Liquid ring vacuum pump with high performance and low maintenance costs.

EXCELS IN THE DETAILS

Tool cooling with internal and external water supply

Spindle vertical travel of 300 mm, with distance of 520 mm from spindle nose to work table, performing slotting on small blocks

The spindle is mounted on a rigid cast iron structure, minimizing flexions under any working conditions

Digital motors

Vacuum system with frontal controls, conveniently located for the operator

Axes “rapid” movements of up to 50 meters per minute In-line tool store located on both internal sides of the machine

ISO 40 standard tool mounting shan

4th C-axis (optional)

A SPINDLE DESIGNED SPECIFICALLY FOR MACHINING STONE

Powerful spindle built by Breton, closed-circuit liquid cooled with three large-diameter high-performance ceramic bearings, 15KW at 12,000 rpm, specifically designed and built for machining stone, engineered stone and ceramics.

ISO 40 tool mounting shank, easily and economically available, even in the aftermarket.

SIEMENS: A WINNING PARTNERSHIP AND A SYNONYMOUS OF RELIABILITY

USER-FRIENDLY CNC CONTROL UNIT

Contourbreton NC 300 EVO incorporates the ultimate generation of the Siemens Sinumerik 840D SL computer numerical control (CNC), a digital control compatible with PC architecture, and a PC based on Windows 7 operating system. The control panel is swiveling, provided with keypad and color-touchscreen with USB port. A portable button panel duplicates the main machine controls (axes management + handwheel, emergency stop, etc.)

consenting the operator to carry out and closely monitor all those delicate operations directly on the workpiece to be machined.

SOFTWARE

Breton SmartCam Countertops, the CAD/CAM software for the production of countertops on countoring centers

Breton Sentinel, the machine data collection and monitoring solution
