Fatronik, in constant evolution
On the issue before us, the high speed, the Center has developed in the year 2000 all its investigations in the area of the machine tool. It is quite significant to point out that the vast majority of projects carried out by the Centre in
collaboration with companies (listed as a competitive research under contract) were developments of machining at high speed or high-performance, data that says enough about the current interests of the industry.
These projects should add another strategic turn about the development of modules of machining of high speed for their integration into flexible lines.
New generation of machines
This is achieved through the development of flexible machining modules. The module is powered by linear motors thereby accelerations of the order of 20 m/s2 and speeds of 120 m/min on the 3 linear axes are achieved. Added to this is a main spindle with high speed of rotation and rapid changes of tools.
This development is achieved a machining center of high productivity and high dynamics that requires the development of new processes. On this point, Fatronik has proven milling by interpolation and the threaded by strawberry.
Collaborations with companies
The projects dealt with on the behavior of the spindles to balls of high speed, the cell of milling intelligent high performance for the production of moulds and dies, the development of a new generation of machines at high speed with a good quality/price ratio and finally the machining of high-performance applied to the machining of forging dies and molds injection.
High speed projects
Behaviour of high speed ball spindles
This project had as object clearly define wear and the useful life of a spindle ball when working at high speed. This has been studied the capacity of the drives based on ball spindles to meet the requirements of accuracy and speed of the machine tool manufacturers. However, increase the speed in a mechanism based on spindles ball presents various mechanical restrictions: the peripheral speed of the rolling elements and the critical speed of the axis of the spindle.
Therefore had to define both factors, so it has conducted a study of kinematics of rolling balls and the dynamic behavior of the axis of the spindle.
Development of a new generation of high-speed machines that price, performance and quality are related in the market
In collaboration with Ibarmia, has been a new series of machines with a large increase in the speed of advance (60 m/min) both Acceleration (8 m/s2 X - 10 m/s2, and Z). This will reduce machining times and therefore increasing productivity.
The speed of this machine head reaches the 15,000 rpm.
Machining of high-performance applied to the machining of dies for forging and injection moulds
They are part of this draft resolution of a significant set of moulds and dies by companies. To this end a milling machine gantry high speed, technology CAM and simulation of processes has been used. The aim was to develop strategies for the Court to increase productivity, as well as the dimensional and surface quality of the machining.
With this activity, the Center has gained experience in machining of high speed of moulds and dies, whose most notable aspects are:
-Machining of parts of complex surface geometry
-High hardness of material of the piece above 30-52 HRc.
-Mechanized with tools of small diameter and great slenderness, even in molds of size medium - large.
-Chip flow environment to 300 cc/min in steels steels tempered at 2,400 rpm
-Excellent surface quality
High-performance projects
Cell of milling intelligent high performance for the production of moulds and dies - is called project HISIM and is carried out in collaboration with the Goratu signature. It consists of the development of a milling machine equipped with a system of power plant process high-speed gantry. It has been adapted for the complete machining of moulds and dies of medium size.
Leading edge research
Aeronautics
The role of Fatronik in the development of the aviation industry has much to do with the work of this Centre on development of parallel kinematics. Fatronik participates and coordinates the European MACH21 project (last programme Growth), who wants to give impetus to this method of manufacturing through the study of its application in various sectors, all of them potential users of the machines.
Fatronik is also responsible for the implementation of various technical tasks including dedicated to design and construct solutions of parallel kinematics for its application to aircraft Assembly.
The experience of Fatronik in this sector includes also research technologies mechatronic, automation of processes of riveting and drilling, as well as extensive experience in the automation of the Assembly. Fatronik has several patents in process on these matters.
Fatronik opted for the future
The Fatronik technological centre is oriented towards basic Mechatronics technologies. It is defined as the "technological centre of design and industrial production" and brings together complementary disciplines such as mechanics,
Electronics and computer science.Started 14 years ago in Elgoibar fruit of the Union of a number of Basque companies wanting to invest in research. Currently, comprise Fatronik companies:
ONA EDM, milling Lagun, Industrias Anayak, Gemini, Ladarasa, Doimak, Zayer, Etxe-bar, Sacem, metallurgical Burceña, machinery JAtor, Ibarmia, exotica, Tekniker.
Its aim was to address the needs of the sector of machine tools by means of a policy of specialization in lines of strategic importance. This commitment has led to the Centre to target disciplines of art, such as aeronautics and renewable energy.
In addition to this change of orientation, the Centre has restructured its organizational structure for adapting the areas of knowledge to the needs generated by the industry.
Fatronik has participated in several European projects through consortia of high level and is an active part in various international forums.
The latest venture of Fatronik is the headquarters of the technology centre, which responds to the need for the Centre to invest in their development and future needs.
