Machining accuracy and speed, these are the strong points of the Matrix 1.000
Dynamic, the Breton gantry-type machining centre with moving bridge has heavy-duty shoulders manufactured using the ground-breaking Metalquartz technology.
To face the greatest challenges you need strong, wide shoulders. When milling medium-large components, this sentence represents more than just an idiom; it's a real philosophy of construction.
Breton, with fifty years of experience in the industry, has made this approach theirs, producing gantry-type machining centres with moving bridge supported by wide shoulders to machine large components, strong enough to guarantee a considerable milling capacity.
The jewel in the crown of the Matrix, machining centres is the Matrix 1000 Dynamic.
For all materials
This 5-axes gantry-type machining centre with moving bridge was designed by Breton to meet new requirements associated with high speed machining of large, complex parts for the aerospace and automotive, die-manufacturing and design industries. The Matrix 1000 Dynamic has a 2,200 mm X-axis travel, 1,000 mm Z-axis travel, and a Y-axis travel that ranges from 2,500 to 6,000 mm.
As well as the impressive working range, one of the features that makes the Treviso company’s product really stand out from the crowd is the ability of machining a variety of different materials such as steel, aluminium, resin and composites.
This machine in fact can be fitted with a vast range of electrospindles with continuous power outputs of up to 41 kW and torque outputs of up to 100 Nm, which combined with a rotation speed of 28,000 rpm offers a notable milling capacity.
The software-controlled compensation of the electrospindle’s natural thermal expansion, and its thermal stabilization guarantee high precision machining.
These spindles are housed in the cast iron dual fork head, which guarantees high structural rigidity and an excellent vibration dampening capacity.
High performance models are fitted with Direct Drive heads, where the 100 rpm rotation speed combined with the continuous rotation of the C-axis shows the true potential of the machine when machining complex dynamic profiles with a high level of accuracy.
Metalquartz shoulders
Another interesting feature of the Matrix 1000 Dynamic is represented by the strong shoulders produced using innovative Metalquartz technology: a sandwich structure made of stabilized arc welded steel, with ribbing embedded in a quartz polymer matrix composites.
This exclusive technology ensures a very high structural rigidity and vibration damping, which guarantees a better surface finish and a longer service life of the cutting tools.
The carriage and beam travel on properly dimensioned recirculating roller guideways to ensure machining accuracy and stability. Linear axis speed can reach 60 m/min thanks to the digital drives with brushless servomotors and the ground ball screw and double preloaded ball nut assembly.
To guarantee the highest accuracy, the position of the beam and carriage is read by optical scales.
Customization
Performance at a dynamic level, offering high power and precision, are not the only advantages, and the machine can be customized with a series of accessories to meet the customer's specific requirements.
In fact Breton also offers wheel-type or chaintype tool magazines with a fast manipulator to reduce tool changeover times.
These magazines are installed outside the work area so they can't come into contact with milling dust or residues, and can be fitted with a system for the automatic encoding of tool data and a chip reader for an even higher level of plant automation.
On the basis of the milling operations to be performed, the tool cooling system may use compressed air, a spray mist system, or coolant sprayed inside and outside the spindle at a set or variable pressure of up to 70 bar.
For customers machining composites and resins we can supply dust extraction systems to install on the spindle nose, and top-roof bellows to isolate the work area from the surrounding environment, protecting the operator from any noxious or harmful elements.
The fact that all the kinematic mechanisms have been located at the top of the machine is proof of the focus on operator safety. Finally, to meet every possible application requirement, the Breton Matrix 1.000 Dynamic can be configured for pendular machining in two work areas.
