In the 2006 BIEMH Tekniker

For a few years, Tekniker devotes part of its investigation of specialization to the domain of magnetic fields in the service of industrial applications. Reflection of this concern and sustained course of action have been the presentations made at the previous biennial two, first a prototype test of head magnetic lift and, two years later, a fully operational prototype implemented on the milling of high speed "bizkor". On this occasion Tekniker gives a great qualitative leap and presents its Bureau supported and driven magnetically.

The device, which acts on 6 degrees of freedom to ensure the levitation and positioning in two dimensions, has dimensions of width 880 mm, 850 mm long and 260 mm in height. The movement is made on a retángulo of 172 x 120 mm, being able to achieve an acceleration of up to 2 g. The system achieves a great accuracy with the use of encoders laser (0,2 µm resolution) or, Alternatively, a greater economy in less demanding applications and through the use of low-cost sensors. The mass of the moving parts of the table is 90 Kg (may carry, in addition, parts of up to 100 Kg), being the actuator capable of transmitting a force nominal up 1,000 n, in every one of its axes.

The scope of application of this new technology is very promising, and covers advanced machine tools and, by extension, any machinery to move and position accurately subject to manufacturing and assembling parts or elements.

Thus, they are conceivable contributions to the machine of machining of high precision (by elimination of the accumulated errors in conventional mechanical systems), on the border, it could be acted entirely by magnetic fields (header, table and cars). Equally encouraging is the field of application in management systems for parts that require clean environments or in vacuum.

As in the previous case, individual, and also in the framework of the Centre for research cooperative Margune, Tekniker has opted for the laser as alternative advanced processing of materials by boot.

As advance what Tekniker will be able to perform in the future, this fair presents a nd: YAG of 2,200 W of power laser head enabling the Centre to trying different processes of input (especially "laser cladding") piece,(welding, temple and, eventually, rapid prototyping).

The "laser cladding" is a technique of contribution, used especially in repair and in the lining of moulds and dies that, with this device, is carried out using optical fiber of 300 or 600 µm and supply of powder nozzles, so that the cord of material has a width of between 0.5 and 2 mm.

In the previous edition of the BIEMH Tekniker presented their capabilities in Microtechnologies, above all in the hands of the demonstrator that constituted the tiny car in less than a gram of weight, manufactured entirely in the Center. Now, it will display its comprehensive range of manufacturing, which implies ability to design the piece and the micromolde, to make the mould, to finalise the process of microinjection and, finally, for preserial production.

To do this, it has a valuable knowledge accumulated in recent years, as well as a leading micro-machining and microinjection equipment. At the fair is to put the emphasis precisely on this final step of the process of micro-fabrication and therefore is going to expose the "battenfeld" microinyectora making preserial short of the dental "brackets" which are produced for the Euroortodoncia client.

The "Battenfeld" is capable of injecting plastic parts between 0.001-0.01 g, with a maximum volume of 1.1 cm3 material and a time for standard cycle of 5 s. In addition, this team also allows making processes MIM (Metal Injection Moulding) and PIM (Powder Injection Moulding), although in these cases the injection should follow you the desbanderizado and the sintered.

Such as magnetism, Tekniker maintains the ambient intelligence surrounding a strategic approach, which already showed some results in the previous biennial. On this occasion demonstrations that are going to make present the results of a research project under contract developed for the JMA (of the Altadis group) company, which is exploring the interesting possibility of incorporating machines of automatic dispatch of supplies of industrial protection, tools, etc., in the way in which this is carried out in the world of food through the "vending" machines.

In particular will be shown how operators can access, through spoken interface, gloves, goggles for protection and other consumables, in a controlled way (radio frequency identification, using TAGs, or sensor networks) and automated.

In addition to the industrial example, also more basic advances in the sensing of elements of the clothing of the workers will be displayed. It is the case of the gloves, equipped with the relevant sensors, can identify the object that is manipulating, which in turn enables the system to provide information concerning the same, without even the human being so requests.

Tekniker has the only comprehensive offer of the State in obtaining of layers by means of physical deposition technologies on phase vapor (PVD); being able to develop new compositions, new processes, and full vacuum chambers.

The BIEMH has been the place where will show recent accomplishments in surface micro and nano structured, order tribológica, as well as the achievement of coatings with very good adhesion on difficult substrates (highlighting the permanent advances in the lining of plastic materials)(, especially to replace some highly polluting traditional processes).

His stand also welcomes the offer of the "spin off" Tekniker "millennium coatings", after attending fairs of as much significance as the EMO exhibition in Hannover or Cevisama, deployed in the BIEMH its wide range of cameras PVD. It stands out as the most innovative, the MIDAS 775, of considerable dimensions, and includes the new evaporators of own development and benefits superior to the State of the art.

They constitute an interesting initiative for the damping of noise and vibration in moving parts of machines.

In this fair Tekniker shows a pair of glued structures that have resulted from the work carried out in the wine project, and which have already been built and tested on one of our prototypes (case of the milling of high speed "bizkor").

As well as mentioned previously, Tekniker exposes its new offering in the field of industrial management software and technology services (petroleum products), analysis of water and waste, dimensional metrology and metalotecnia in consulting oriented advanced industrial manufacturing processes.
