Suspended laser cutting

Simple separation of the parts, zero flashback
and machining of thin gauge materials.

How does it work?

1. Material tensioning
   The material is fed into the laser system and tensioned thanks to two opposing clamps which keep it tensioned longitudinally
   during the cutting phase.
   
2. Swarf cutting
   Once the material is in tension, the laser head starts cutting the waste. which fall directly into a dedicated container. The swarf
   container is easily accessible and easy to empty.
   
3. Cutting the finished part
   The laser head cuts the external shape of the finished part which, depending on the type of production, can be supported thanks
   to the micro joints until the final detachment is programmed.
   
4. Separation of finished parts
   Before definitively detaching the finished parts, a conveyor is positioned longitudinally under the work area. At this point, the laser
   head works on the micro joints causing the part to fall onto the conveyor. This operation is carried out on all the parts present in the
   work area.
   
5. Sorting of finished products
   Once the cutting phase is over, the conveyor takes the parts out of the cutting area, making them fall onto another conveyor
   positioned transversally below.

At this point, the products are extracted from the machine body, ready to be processed and stored in the warehouse.

ADVANTAGES.

Zero Flashback.

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.

Large swarf ejection.

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.

Simple processing of very thin materials.

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.
