New Breton Matrix 1000
Renewed in form and substance, Matrix 1000 of Breton is designed for the needs of mold makers and presents some innovative solutions designed precisely for the specific needs of this sector.
Matrix 1000 is not a new name in the Breton panorama : born for the mold makers market, in the past it has achieved great success. Today, in light of technological improvements and renewed market demands, it has been updated to obtain even greater feedback.
In fact, it has a reduced footprint compared to the previous model, despite the travels of the axes are greater (300 mm more in Y). In the world of molds, workshops often have space problems and sometimes this represents the discriminating factor between choosing one model over another.
The modularity remains: for the Z and Y axes only one size is available, while in X the possibility of choosing strokes from 2,500 to 4,000 mm is guaranteed. In any case, the focus remains on the mold maker.
Speaking of the work area, the Breton designers have provided a cover with stainless steel sheets for the internal compartment: this is a solution that avoids the classic “paint stripping” effect found on other machines. Being able to count on a material that is by definition resistant to the chemical aggression of fluids and mechanics of swarf is an added value much appreciated by users.
Chip evacuation is another feature strongly felt by users. If with steel this need is not so evident, when processing aluminum the volume of chips produced is considerable: milling rotational aluminum molds means starting from large blocks by removing a quantity of material that reaches 80/90% of the total. In this case, being able to count on an efficient evacuator means keeping the working field clean and preventing the accumulation from creating problems for the machine itself. For this Breton has provided a front belt conveyor that allows you to easily open the doors and two lateral screw conveyors that bring the remaining chips towards the front one. The rear wall is also attached to the table in order to avoid the accumulation of material.
The same stainless steel walls also protect the shoulders and the bellows, which thus remain cleaner and easier to wash if part of the chips should accumulate.
The evacuator is positioned in front, with exit from the magazine side (on the right or left of your choice): on the front of the machine the operator has the numerical control, the tool magazine and the chip box, without having to move to the rear.
From the point of view of usability, it is important to remember that electrical panels require a safety distance from other machines to be opened. They are now positioned on the rear of the Matrix 1000, which in this way can be installed up to 1 meter from the wall without encountering critical issues related to safety of use and maintenance.
The axis strokes are equal to 1,000 mm in Z, 2,500 mm in Y and from 2,500 to 4,000 in X.
The motorization is of the gantry type with 4 motors on the master / slave X axis and backlash recovery; Y is moved by a recirculating ball screw with clearance recovery, while Z has two recirculating ball screws without balancing, useful for increasing reactivity during the work phase.
A quill with hydrostatic guides is also available on request: a solution that dampens vibrations even more effectively.
If the use of torque motors with encoders is envisaged for the rotary axes, on the linear ones the company has preferred to stay on a more “traditional” solution, which still ensures high-level performance: the screws and racks ensure up to 5 m / s2 and 50 m / min, but without the typical problems of using linear motors (consumption, design complexity of the cooling system, etc.). Insensitive to heat
This result was not achieved with the use of a large number of temperature probes.
