BRETON HAWX Gantry style 5 axis VMC for composites, resins and low density materials A "gantry" machining center with mobile bridge and 5 interpolated axes to execute high-speed milling and trimming operations on light alloys, resins, and composite materials. BRETON IS A TECHNOLOGICAL LEADER IN THE HIGH PERFORMANCE MULTIPURPOSE MACHINING CENTERS The company occupies a land area of approx. 81.000 m2, of which 40.000 are covered, and employs about 680 persons. Breton has been awarded the ISO 9001 Quality Certification and the ISO 14001 Certification. In the nineties, Breton forced its way in the field of high speed numerical control machining centers, becoming in few years one of the most important manufacturers in the world. Breton's machining centers stand out and are well-known thanks to their top technological level, superior production performances, groundbreaking solutions and undisputed quality of the product/service system offered to its customers. Breton holds the exclusive right on the "Metalquartz" technology applied to the sector of high speed machining centers, which allowed to considerably increase the machining performances. In the course of time, Breton developed a full range of machining centers, that satisfy all the requirements of the following industrial sectors: Aerospace, Defense, Aeronautics, Automotive, Naval, Motor Racing, Gears, Energy, Die, Automotive and Naval Modelling and Prototyping, General Manufacturing Industry.

Equipped With

Construction is sturdy "Box-in-Box" steel bridge. Thanks to the larger size of the box-shaped bridge, the distance between the linear guide blocks also increases, thus drastically reducing frame deformations and provide overall rigidity. The bridge is mover by a "gantry" system, consisting of a precision rack-and-pinon/gearbox system with mechanical preload for backlash recovery, driven by two brushless motors. Foldable thermoplastic bellows cover rack and linear guideways to protect from dust and swarf. Hornet Head on the HAWX "gantry" machining center is orthogonal head for 5 axis machining. This unique head structure features careful repositioning of "A" axis in an offset by 100mm (3.94") from the center of the RAM. This expands the machining area to process longer and wider parts. Both rotary axes are driven by digital brushless motors powering large cycloidal gearboxes, that are directly controlled by encoders.
