At this point, the products are extracted from the machine body, ready to be processed and stored in the warehouse.
Flashback is the phenomenon that occurs during the material cutting phase in machines with traditional supports (fakir bed). When the head cuts the material at the point of contact with the support, it is marked, like a small dark burn. The suspension cutting system eliminates this type of problem: the material held in tension by the two clamps has no points where it rests in order to be supported, so there will never be contact points capable of creating this type of problem.
In traditional laser cutting systems, the supports for the material in the cutting zone cause large pieces of swarf to be cut into smaller parts, so that they fall between the spaces left by the supports. In this case, the suspended cutting system also completely eliminates the problem, leaving the cutting area below the material completely free from supports. Large pieces of swarf can fall directly into a special container, reducing production times compared to traditional machines. The same principle applies to the waste skeleton in the case of production involving lots of parts inserted into the work area. Once the finished products have been extracted, the skeleton is dropped directly into the container without having to carry out further processing with the laser head.
When it comes to processing very thin materials using traditional laser cutting systems, it becomes difficult to guarantee the precision of the machining due to the vibrations that are triggered by the gas jet from the laser head. With the exclusive Dalcos system for suspended cutting, the material is held in tension thanks to two opposing clamps and the pulling force is adjusted for the type of material used. Consequently, there’s always an optimal level of tension, so as not to create vibrations or weaken the material. Thanks to this technology, it’s possible to process materials up to 0.15 mm in thickness.
