Breton vertical machining centre XCEEDER - 5 axes for Formula 1

It's a common belief that Formula 1 is the realm of speed. Actually, Formula 1 is rather the realm of acceleration, the vector enabling to reach an extremely high speed in a very short time frame.

That's why F1 racing teams ask the specialized manufacturers of rims to perfect their products so as to reduce their weight as much as possible.

In this restless seeking for lightness, the rim is engineered using the most advanced techniques such as the finite element method (FEM) that highlights the stress distribution in the piece, thus revealing the less stressed areas which can be reduced in size or thickness.

Indirectly, the FEM also enables to find the ideal geometry that allows optimizing the strength-to-weight ratio.

In most cases, the very special rims for F1 are hot forged and then turned and milled.

The extent of these machining operations is amazing: just consider that some rims weigh 35 kg when forged but once the machining is over and all the parts which the FEM considers as non-essential in relation to strength are removed, the rim weight is 3,5 kg only.

It goes without saying that high-grade machines are required to perform so complex and delicate machining operations: the control on five continuous axes and a piece holding table enabling to position it wherever it is needed are absolutely necessary.

Furthermore, since small-diameter tools are often used and pieces to be machined are made of light alloys, the spindle must feature an exceptionally high speed which just a few machines can develop.

On the other hand, such a high speed may involve vibrations that could compromise the surface finish and the miller service life, that's why an utmost rigidity and static and dynamic stability are required.

At present, very few machines meet all these requirements for real whereas Breton vertical machining centre XCEEDER 1200RT copes pretty well with all of them.

MATRIX 1000 - Ideal machine for aerospace, automotive and die-manufacturing

A competitive solution 
High-speed precision machining centre for milling complex three-dimensional work-pieces which require accurate machining and continuous axis interpolation.

MATRIX 1000 is the ideal solution to satisfy production requirements across a multitude of industrial applications from aerospace industry to automotive, die-manufacturing and design.

Wide choice of configurations for customized performances
Various solutions for the best machine configuration to satisfy each need:
- Standard model with one working area
- Model with two working areas for pendular machining.

Easy access and perfect visibility
Great accessibility and visibility of the working area thanks to the machine gantry structure with moving bridge and wide frontal doors.

High precision, dynamics and speed with 5 continuous axes
In order to ensure high performances, the new MATRIX 1000 is provided with heavy-duty shoulders manufactured using the ground-breaking Metalquartz technology.

Shoulders consist of a sandwich structure made of stabilized arc welded steel, whose ribbing is embedded in a quartz composite material with a polymeric matrix. 
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.

A superior head
The electrospindles offer always the best machining performance thanks to the cast-iron fork designed head which offers structural rigidity with efficient vibration damping properties. The most high-performance machining centres are provided with Direct Drive motorized heads.

High-speed, Performance and Precision
The carriage and beam travel on properly dimensioned recirculating roller guideways ensure machining precision and stability. Axes are moved by a ground ball screw and double preloaded ball nut assembly.
Maximum axis precision is achieved thanks to the micrometric technology applied. Axes are powered by digital drives and ultimate generation brushless servomotors.

Wide choice of electrospindles
The MATRIX 1000 machining centre can be supplied with a wide range of electrospindles depending on the type of material to be machined. Machining precision is always guaranteed by the thermal stabilising system which consists of a special software designed and developed to compensate natural thermal expansion in the electrospindles when machining conditions vary.

M38/28
A 20 kW electrospindle with a 38 nm continuous torque in S1 and 28,000 rpm is the ideal choice for high-speed machining requirements for steel and light alloy from rough milling to precision surface finishing operations.



M51/28
Electrospindle featuring a power of 40 kW, continuous torque of 51 Nm in S1 duty and 28.000 rpm: the ideal choice for customers requiring high-speed machining on either steel or light alloys, from rough-machining up to precision finishing.



M100/18
Electrospindle featuring a power of 40 kW, continuous torque of 100 Nm in S1 duty and 18.000 rpm: smartly performing any machining operation on either steel or light alloys, from rough-machining up to precision finishing.

Simple and reliable tool magazines
According to the various models, wheel-type or chain-type tool magazines with fast manipulator to reduce tool changeover times are available. Installed outside the work area and therefore free of dirt, these tool magazines ensure the greatest reliability over the time. 

They can be equipped with an automatic chip coding system containing tool data and information.

Dust extraction and ceiling enclosure

When machining composite materials and resin, MATRIX 1000 can be fitted with an efficient and effective dust extraction system which is installed on the spindle nose. In addition, top-roof bellows can be fitted to the machining centre creating a complete enclosure isolating the machine from the surrounding areas. 

Different models of dust extraction systems are available to satisfy any customer’s requirements.

The ideal cooling system
Depending on the type of machining, the tool cooling system can use a coolant liquid which flows inside and outside the spindle (60 L/min) with fixed or variable (up to 70 bar) internal pressure, or incorporate a spray mist system, or simply use compressed air.

Monitoring and in-process inspections

MATRIX 1000 can be supplied with a laser tool presetter and a radio frequency probe for acquiring work-piece size and coordinates.

So, why don’t you request a quotation for a MATRIX 1000?
