Innovation is settled

It had an impact on the importance of finishing machine and the aesthetic appearance of the fairings and negatively stressed machines "aesthetically not attractive". In this connection, the closure of the machines, making them similar to machining centres, is growing.

The presence of five axes of dimensions larger models, each time either with rotating tilt tables, or with the axes of rotation in the head, is a necessity of end customers that manufacturers are responding.

For the fourth axis you choose to integrate the turntable at the table, to avoid losing vertical course.

There was a trend towards the use of the devices of changes of pallets in these centers of machining of high dimensions, with architecture portico of Bureau mobile and rotating, and high performance.

Domestic manufacturers showed the most significant stands (CME, Anayak, Nicolás Correa, Zayer, Soraluce, m.v.. E…). In this regard, he highlighted the aesthetics of Nicolas Correa (national design award), and the stand of Soraluce.

Note also the presence of manufacturers Italian as FPT and Rambaudi, who visited the fair for the first time with a machine in their stands.

On the other hand the integration of milling in architecture of horizontal lathe, is proliferating in horizontal torno-fresadores of pequeño-mediano size.

However, there is so much abundance of large size torno-fresadores.

In general it is machines with a great modularity (in turrets, head motorizado…) and option of all controlled axes (axis B, C, and).

It confirms the evolution of traditional manufacturers of machining as DMG, Mazak, Mori-Seiki machine with larger centres, with a clear trend towards multifunctionality

The integration of several different processes on a single machine is another clear trend that is occurring in the technology of turning, for a time this part.

It also warns the growing presence of lathe pick-up of axes, both horizontally (Danobat, Emag, Weisser), as in vertical (Emag, Emco, Famar, Schuster, Buderus). Through this last configuration, thanks to the vertical arrangement of the piece, is to gain space on floor.

The inclusion of numerous devices on vertical, is important to optimize the final solution:

• charge-discharge in the own cabezal-pieza (concept pickup),
• devices of transferización of piece (clamp conveyor in swing arm, gripper in turret, swing with intermediate station), with presence of patent (Schuster, Hessapp)
• post-process measuring systems,
• auxiliary devices based on laser welding, band Sander or shovel for killed hélice…

In these machines is beginning to offer the option of grinding for threads.

The dimantadores of the grinding wheel can be off the phone table, in order to thus lighten the movements of the cars and get higher speeds and accelerations.

On the other hand, it is worth noting that the presence in grinders without centres was based on domestic manufacturers Estarta and Seny.

The growing tendency to use electric drives for the punching machines type turret, with the presentation of the new model of punching machine of Rainer turret was found in this fair.

The Trumpf booth combined the monoútil punching machines with laser cutting machines and manual cutting tools. On the other hand, in this fair also featured a new punching machine type turret of the Turkish manufacturer Durmazlar.

The national manufacturer Goiti, received the national design award in the section on deformation, with the presentation in competition of its new punching machine of turret. This new punching machine is noted for the ergonomics, the cadences of production and the orientation towards the high productivity of its design.

In this regard, two of the most significant stands were those presented by the German manufacturer Kaltenbach and Danobat saws.

Both booths presented a robot suspended in a portico, with up to 7 degrees of freedom, and a system of thermal cutting (plasma or oxy-cutting), prepared for the three-dimensional cutting of structural sections.

The complexity of these systems lies in the development of a software capable of performing these cuts in structural profiles of varied and complex forms.

In the rest of the stands, the orientation towards the machining of high speed machine more rigid structures, band saws alloyed materials type carbide, are being implemented in this niche market.

Predominated the machining centers with horizontal structure, changer arm of tools on the right side of the machine, and Z axis by moving the pallet.

They include the high speed (20,000 rpm) submitted by the manufacturer Kitamura, in a head driven by gears.

In General, is you can talk consolidation of linear engines for certain applications of machining parts of aluminium, and specific manufacturers, DMG.

Comment of the other part, stagnation in innovative structures type hexápodos, although there are manufacturers of concrete and MTorres Loxin 2002, which still used them for applications as the mechanization of parts of aeronautics.

• Magnetic bearings: Tekniker in collaboration with Goialde, introduced a high speed (48,000 rpm) head made with magnetic bearings. It has two radial bearings and axial one. Radial bearings consist of two pairs of Poles (one for each axis of the plane), and have inductive position sensors to close the control loop. The bearings are controlled by a hardware specific, separate own numerical control, and controlling the system at a frequency of 8 KHz sampling.
• Fidia drives: the Italian manufacturer of NCCs's reference to the world of high speed milling has released its own range of drives. So far the Fidia controls were mounted with Siemens or Indramat (Sercos) drives. Now, Fidia completes its offer with own drives known as XPower, serving both axes and head. They use a proprietary digital bus, FFB, at a speed of 112.5 Mbit/s. A set of software tools that facilitate its adjustment and implementation underway will complete.
• Direct motor ripple reduction: Heidenhain presents a new type of incremental encoder for applications of positioned in direct engines. These encoder ERP 880 provide 90,000 pulses per lap with a resolution of ±1 ", appearing as a substitute for the encoder magnetic was 800. A demo available at the booth of Heidenhain where comparing an axis controlled with both types of encoder, noted a drastic decrease in torque ripple.

In both cases, the systems are presented for control and monitoring applications focus on processes such as turning, threading, drilling and milling, no notable references of equipment installed for the grinding (e.g. in the case of applications of adaptive control).

Monitoring and diagnosis strategies focus on both cases on the use of fixed limits and sheath patterns of a characteristic sign of the State of the process, focusing mainly on detection of breakage and tool wear, while the applications of adaptive control of process focus on control-online on the progress of machining to ensure a constant cutting power.

Fagor presented some applications integrated into its open architecture 8070 CNC: the intelligent profile editor facilitates and simplifies the creation of profiles without having to do complex calculations; the control performs a monitoring of the life of the tool by controlling their use.
