RIGIDITY BECOMES DYNAMIC

Matrix 800 design has focused on the development of an extremely robust structure to guarantee the necessary thrusts and stiffness to perform high-feed roughing, top-of-the-range semi-finishing and finishing operations and, at the same time, to offer the ideal dynamic, speed and accelerations for those who are looking for the highest production performances. Several design choices allowed achieving this level of stiffness, for example its monobloc structure and the bridge/RAM structure, among the strongest in their category. This great solidity has been perfectly improved with special technical devices in order to keep high dynamics. For example, High Dynamics technology allows considerably reducing friction factors, especially those caused by the balancing system, thus obtaining jerk, accelerations and speed never seen before in a machine with such thrusts. This means not only excellent levels of precision and finishing quality, but also a significant reduction of operating times.

1. COMPACTNESS

FOOTPRINT EFFICIENCY RATIO >> 28.3
The space in a company represents a cost and often old machines, whose strokes are perhaps reduced compared to current needs, must be replaced. In order to solve this problem, we decided to maximize the ratio between machine size and axis stroke, focusing on what we call footprint efficiency ratio.
The machine develops transversally for multiple reasons: customers’ preferences (83% of users prefer machines with transverse layouts), possibility of placing the machine’s backside against the wall, improvement of visibility for the operator and possibility of delivering it already assembled, thus allowing for economic saving and halved installation times at site.

2. HIGH PRECISION

The new Matrix 800 aims for the highest level of precision. The whole structure is thermo-symmetrical to evenly respond to temperature variations: since it expands evenly in all directions, it keeps the precision high. The optical scales are symmetrically centered as nearest as possible to the guides in order to obtain higher precision. Our patented Thermal Shield technology considerably improves thermal expansion control and reduces structural deformations without using expensive cooling systems. This technology creates an advanced thermal coat that keeps the temperature between structures and workpieces as stable as possible. The innovative Matrix 800 electronic stabilization systems monitor temperatures and any expansion on workpieces, synchronizing them with those of the machine structures. Even the RAM, that with a section of 450 x 450 mm is among the sturdiest in its category, is fixed to the carriage by means of 6 roller pads, three per side, in order to support all the efforts and ensure a high movement speed.

3. REDUCTION OF INSTALLATION TIME AND COSTS

Particular attention has been paid to installation time and costs. The rigidity of the monobloc structure allows for simple flat foundations. All this has been studied to minimize the use of anti-shrinkage cement and chemical anchors for ground fixing. In addition to the costs of these materials, the solution also makes it possible to avoid time-consuming construction works for the preparation of the area where the machine will be positioned.
The market is increasingly responsive to delivery times. Once a customer needs to invest in a new machine and has identified the necessary features and customizations, he wants to have it in place as soon as possible. To satisfy these requirements, we have reviewed the entire assembly flow of the machine. The choice of a transversal orientation of the monobloc structure makes the Matrix 800 transportable with the main structures already assembled. In this way, we lead the Customer to have a significant saving in costs and installation time. In fact, in the standard version, it only takes 2 weeks to pass from the receipt of the machine to its production start-up.

4. MINIMIZED OPERATING COSTS

Matrix 800 - stainless steel working area

During the design phase, we paid great attention to the aspects that bring added value. The kinematics and mechanisms lubrication has been totally reconsidered, by replacing the traditional systems with an advanced distributing system that eliminates the most common problems such as dirt, stains and dangerous vapors as well as high maintenance and operating costs. The entire cooling system is static so that the customer does not waste even one kW. Where other manufacturers use expensive cooling and ventilation systems, we have decided to intervene with special technical solutions, such as the thermo-symmetrical structures and the Thermal Shield. A clean machine is known to last much longer. For this reason, the work area is covered with modular stainless steel panels that not only keep themselves cleaner, but also remain virtually unchanged over time even if continuously exposed to dust and chips. Combined with the efficient chip discharging system, they allow the work area to be kept free of chip build-ups and safe for operators, who will thus devote their time to more profitable activities.

5. VERSATILITY

This machining centre guarantees enough thrusts and rigidity to perform high-feed roughing and top-of-the-range semi-finishing and finishing operations.
At the same time, it offers the ideal dynamics, speed and accelerations for those who are looking for the highest production performances even on the most demanding parts made of hardened steel or non-ferrous metals. Matrix 800 is designed to fully meet the needs of 3 sectors: Aerospace, Mould&Die and composite machining.
Each version features specific accessories to guarantee the best performances and services according to the parts and materials to be machined.

Matrix 800 Mould & Die version

The version dedicated to the Mould & Die market includes the use of the Typhoon orthogonal head with electrospindle ranging from 52 to 137 Nm and from 16,000 to 28,000 rpm. This version is equipped with a system for chip discharge with screw conveyors that push the material coming from both sides of the table towards the front conveyor belt. Customer has the total freedom to choose the tool store to be installed in combination with our tool changer for the management of pre-selected tools and the reduction of times.
Matrix 800 is designed and tested together with both suppliers of the most advanced CNC systems so that its features can enhance the functions provided by the electronics to improve the precision and finish of the machined parts. It can therefore be equipped with both the latest version of the Heidenhain numerical control and the brand new Siemens Sinumerik One control, of which we have been co-developers and partners selected for the launch.

Matrix 800 Aerospace version

The third version is dedicated to the Aerospace market, where the machine is calibrated to provide maximum performance in high removal of aluminum or for milling of rolled steel and titanium. The Matrix 800 is thus equipped with a fork head, available in the Ghibli, Phoenix or Tornado models, and with enhanced chip discharging systems, as well as with particularly efficient fume extraction systems.
And it's first and foremost in these aerostructure installations that our Accuthick and Advanced Countersink technologies are perfectly combined: the first is dedicated to the "lightening" of structures and laminates where it is essential to ensure a constant and precise final thickness, while the second is dedicated to the adaptive correction of the angle and depth of drilling / countersinking.

Matrix 800 for Composites machining

Matrix 800 is also the right choice for those who need to machine high-precision composite parts. The sturdiness of the machine allows high dynamic machining with unequalled precision. For these applications, the configurations provide for a wide range of special accessories including a dust extraction system on the spindle nose and/or on the table rim (environmental) combined with high protection of the mechanical parts of the machine through the pressurization systems of the drives, heads and spindles that have always distinguished our machines for the guarantee of reliability and durability over time. Moreover, thanks to the experience acquired in the most particular and complex applications, it is possible to implement innovative and highly efficient solutions in the filtration of the coolant used in particular composite processes.
