Laser Reducing
 
Laser slicing know-how enables replacement of many conventional cutting solutions, which delivers price tag savings to the consumer. The largest gains are received when cutting complicated styles for tubes and profiles, and when dimensional precision is crucial. Reducing good quality and precision are exceptional in comparison to other procedures applying thermal warmth. Laser cutting is usually suited for processing of extremely high-strength steels. Using the benefits of laser slicing into account in product or service design and style means shorter product guide moments.

QCCO features laser processing expert services in a huge dimensional assortment. It is possible to minimize spherical tubes from fifteen mm diameter precision tube to major tubes obtaining diameter up to 508 mm. Square tubes can be minimize approximately 400 x four hundred mm in dimensions. The maximum materials thickness can be 16 mm as well as the 3D-cutting software also permits reducing of bevels for welding. The utmost end-product size is fifteen,five meters. Laser machines signifies designs is often slash on each side with the slab and additionally, it allows forming from the tube ends.
Sawing
 
QCCO provides huge production capasity for straight and angle reducing of tubes, beams and bars. QCCO have also modern circular sawing equipment lines for specifically reducing precision tubes likewise as more compact hollow sections. Automated product dealing with along with the most up-to-date know-how of sawing provides high productivity and excellent. Tube ends is often deburred in the course of the course of action.
