Junyi laser flattening and coiling machine successfully delivered six-roll processing equipment

Why does laser cutting need a leveler? There are currently thousands of laser cutting machine brands on the market, with varying levels of quality. Although the cutting technology is mature, thin plates below 3mm should generally not be deformed when cutting. However, during actual visits to customers by Junyi Laser, we found that not only medium and thick plates, but thin plates are also severely deformed.

The reasons why laser cutting sheet metal may deform are: the sheet has not been leveled, the surface is uneven, improper cutting operations, incorrect parameter settings, aging equipment, uneven power output, temperature changes in the factory, uneven nozzle airflow, or different batches of materials The material is unstable, etc., which will cause cutting deformation, warping or distortion. The above factors are avoided. The principle of laser cutting is to melt metal at local high temperatures, which can also lead to thermal deformation of the surface due to uneven cold and heat. This is a common pain point encountered by customers.

Once thermal deformation occurs after cutting, subsequent welding and riveting will be affected. The flatness of the product, the verticality of the box, the diagonal tolerance, surface and structural quality, and sealing will all be affected, making it difficult to pass customer acceptance. And one scrap product may eat up the profits of dozens of processed parts.

To reduce defective products and produce high-precision sheet metal parts, it is necessary to level the material before entering the cutting machine. After cutting, use a leveler to level the parts to eliminate stress.

What is the current status of leveling in the sheet metal processing industry? At present, a large number of sheet metal companies do not have leveling configuration before entering cutting. After cutting, they only use presses, hammers or flames to manually level the parts with visible deformation. This requires experienced employees, and the leveling efficiency is extremely high. Low. There are many cases of sheet metal parts that have not been leveled deformed after welding or spraying. Many companies look for the cause in bending compensation and materials, and do not even realize that the stress of cutting is not removed, resulting in scrap. reason.

Users in the industry who have purchased Junyi Laser's laser cutting equipment can produce flat, stress-free sheet metal parts of various sizes. The workload of subsequent bending angle correction is reduced by 50-70%, making automated welding smoother and the finished parts tightly fitting. It is the first choice for sheet metal manufacturers in the medical, electric power, communications, electronics and other industries, and can meet the requirements of high air tightness, high precision and high quality.
