Industrie 2002 showed throughout the production process
you products are also subjected to quality controls and measurement operations and mounted in processes where the time is vital. In order to avoid any deviation, which could lead to incidents or rejections, machines, equipment, assemblies, tools in themselves are also subject to quality control and dimensional controls. So Interqualité and Euro Assemblage provided innovative solutions. Everything is managed and optimized by computer, usually connected to the computer network. They were present in the space of Ind.ao.
In the last 15 years the industry has experienced more new developments than in the previous 50 years.
For 7 specialized exhibitions present in Industrie 2002, the year of the Mechatronics will continue to the years of the first hexápodos, pneumatic stations, digital hydraulic, machines for dimensional control in plant or the disappearance of the control cabinets.
Best response to the expectations of manufacturers
The same applies to the water where people need help loading or pressure and digitally programmed memorized positions and shock absorption. In pneumatics, the miniaturization of the units of control runs parallel with the multiplicity of types of connections: flexible, flat, rotating diaphragm, rotolineal, etc. For the movement of loads, users want systems that are easy to implement and connect, significance for themselves and that if necessary, you can program directly on the machine.
Mechanical organs, ball spindles or mounts of the wheels you, should be increasingly rapid. The same time, the engines, boxes change, bearings, etc., which must equip the machines, are subject to the directives of the EU on limitations of noise, solutions that should be found.
Manufacturers also incorporated more and more sensors in the mechanisms. This process is necessary to ensure the control of the process, the availability of the product and its maintainability. This can be seen in the connections (for movement), bearings (for speed and positioning), engines, etc. Today they are more focused on cutting tools, together, couplings, morning in functions and today we have come to realize. Finally, networks are adopted many times to connect local and centralized functions. Even when the systems are different manufacturers want the components to be able to communicate between if and exchange information.
Increase of 30% with new machine tools
- -Combination of different processes of machining on a machine. The new machine tools incorporate various functions of machining, such as turning, milling, turning hard, drilling, threading, grinding, machining of you gear, and for tomorrow is expected to carry out thermal treatments in the machine by means of laserallowing that one-piece mecanice completely in a machine.
This development is on many lathes and machining centres for example, Nodier - Emag has developed the 250DS VSC and the VSC 400DS, vertical lathes pickup that combine the process of turning, drilling, milling and grinding.
Yamazaki Mazak available of Integrex e-1060, a center of multifunctional machining, turning and milling 5 axes in one tied pieces large (diameter 1500, height 1.445).
- -More powerful machines. The other line of development is the use of new technologies of motorization in machine-tool, as it is doing in lathes and machining centers, incorporating linear motors that ensure high speeds, large accelerations and great precision.
Ernault, of the Cato group, presented the Centre of turning Rubis, of 2-5 axis with linear motors. The speeds in the Z axis (longitudinal) and X (cross) reach the 90 m/min and a few accelerations of 10 m/s2, while the accuracy can be achieved is a tenth of a micron.
According to the specifications of the manufacturer, the increase in productivity varies between 10 and 30% depending on the piece to mechanise.
In high speed machining centers, Renault Automation Comau has launched the model Uranus, which is in full swing in the factories of PSA and Renault. PSA, entrusted for example Renault Automation Assembly of a line that includes 29 Urano machining centers, equipped with linear motors, to produce 1,200 butts to the day.
An example that shows the combination of machine with linear motor technology architectures, is found with the same manufacturer. Urano SX model is specialized in the drilling, milling and threading operations. Use a parallel structure and control of the axes using linear motors for a ultra shift quickly from point to point (speed 100 m/min and acceleration of 35 m/s2).
- -New machining processes. Finally, new machining processes ensure productivity gains. Trumpf, with its center of punching laser 2D uses Hi - Las Plus (fast cutting with high pressure of nitrogen) and PMS (monitoring system, Plasma) to aluminum and stainless steel. According to the manufacturer, the speed of a 1 mm thick aluminium sheet cutting passes of 12.5 m/min up to 40 m/min.
- -Numerical controls. Digital controls manufacturers have placed his knowledge at the interface of the machine and the reduction of errors in machining at high speed. A good example is the control of Heidenhain (represented in Spain by Farresa electronics) ITNC 530 offers ease and speed of programming, efficient control by means of graphics tests, speed of data transmission between the control and the server of CAD, time of very rapid processing of the blocks, etc.
Other manufacturers like Amada bending or Siemens in machining offer software that allows to increase the productivity, without penalising the ease of use. In this way the new beloved CAD/CAM software for the folding offers a very intuitive dialogue of man machine interface, through a touch screen. Siemens, ShopTurn software for turning and milling favours programming directly on the machine, while it is mecanizing, for the next parts. To avoid rejections operator can simulate the piece in 3D before machining her.
Spanish presence
Ibarmia, for example, offers a wide range of machining centers of mobile column (axis x 600 to 6,000) and axis Y: from 410 to 1,000, speed electro spindle up to 18,000 rpm, speed of up to 60 m/min. Some models can be fitted with a tilt head. This manufacturer also has a machine in 5 axes for high-speed machining.
For its part, Industrias Anayak introduced a milling of fixed frame and table mobile phone with integrated table VH-PLUS-3,000 - MG. This machine is equipped with an automatic head of 3,000 rpm and a warehouse with a capacity for 20 tools with changer in vertical and horizontal position. Machine designed for the machining of high speed with head of 15,000 or 20,000 rpm.
As for Danobat group, presented by each of its companies a representation of the products most significant, highlighting the NA-500 lathe for machining hard with head hydrostatic, oriented to the automotive sector, which allows it to offer a high precision and rigidity.
