Tecoi bets on the bezel cut by its performance and functionality

The head of automatic bevel, the revolution in technology Court

The Tecoi Court, S.L. company has always focused on the manufacture of machines of sheet metal cutting by incorporating the latest technologies. In this way we get a product of high performance and reliability, allowing that our machines are versatile and with large production capacity. In this regard, we are in continuous development of applications to ensure that the level of finish of parts is more complete and require the minimum number of additional operations to achieve the final product. One of our products is the automatic bevel head.

A brief history of this type of elements and their key features is set out below.

Already about twenty years ago began to check capabilities to plasma and laser could contribute to the boiler and metal construction. Today, technology plasma and laser offer key productive advantages and objective versus other technologies in the sector of the metallic composition from thickness thin (0.4 mm) until media thickness (60 mm). Also, technology and equipment of cutting machines is has been adapted to current plasma and benefits of the laser in order to make maximum use of these technologies and make more flexible and productive cutting machines.

Practically all parts metal weldable from 8 mm thick onwards needed preparation of edges to be welded in a reliable manner and according to rules.

One of the greatest advances in the field of cutting machines are, without doubt, the automatic bevelled cutting heads. These systems have possibly represented the greatest technological revolution in cutting machines current, allowing manufacture parts with a level of practical and very important finish. Currently, all metal construction companies are finding the complete solution to the problems of preparation of edges for welding in these headers, reducing the costs of preparation of piece in an amazing way.

Practically all parts metal weldable from 8 mm thick onwards needed preparation of edges to be welded in a reliable manner and according to rules. It must be borne in mind that the more usual range of thicknesses in boilermaking goes from 4 to 40 mm, so the preparation of edges is essential in 90% of the work. This has become a global necessity.

Since several years already, they exist in the market heads referred to as second generation, based on functions of 5 axes numerical controls.

The most commonly used angles today range from 15 ° to 60 °, although normal in all cases is to prepare edges with bevels between 20 and 45 °, depending on the type of work and the sector. It should bear in mind that the ability of the system of court must measure depending on thickness and angle that are required.

There are several types of bevel for plasma and laser heads. On the one hand, they are the classic rotating heads composed of an angular axis and other rotating axis, which have been quite used on machines with traditional numeric controls without 5-axis control. Mechanically, these systems are quite complex and above all very bulky and abundant and complex maintenance. One of the major constraints of functioning of these systems is the need to 'rewind' rotating shaft angle of the edges of the piece changes, necessitating the use of a large space between parts (20 to 50 mm) in order to make the changes of angle.

New 5-axis systems are the ultimate solution to the requirements of the current work of bevel cutting

There are several types of Heads of bezel. In the image, a plasma cutting system.

Since several years already, they exist in the market heads referred to as second generation, based on functions of 5 axes numerical controls.

In Tecoi we have opted for this technology of bevel cutting their benefits and their functionality. These new systems are the ultimate solution to the requirements of the current work of bevel cutting and avoid all the problems and shortcomings in the functioning of traditional rotating heads. The new systems of 5-axis, as well as allowing infinite spin, do not require any type of greasing maintenance or cleaning. In addition, they need not do loops at the corners of the pieces in the changes of angles with which the use of the sheet is immensely greater.

With the bevel of 5-axis systems today is cutting with benches of court dry, under water or any current bank system. One of the greatest advantages of this system is that it does not require a specialization of the operator to bevels, since the parameterization is done entirely from the CNC. On the other hand, the dimensions of these heads are well suited for the Court with various heads within the same sheet in small parts.

Currently, for laser technology and plasma, the solution of type robot head or 5-axis is the most suitable within an increasingly more demanding with the production sector and the flexibility of the machinery.
