As an advanced material cutting method, laser processing has been increasingly accepted by sheet metal producers. With the continuous progress of computer control technology and optical technology, people have higher and higher expectations for its processing ability. This expectation is not only for being able to cut, but also for cutting well and fast.
At present, the demand for high-power laser cutting machines is increasing, mainly focusing on the growing demand for thick plate cutting. However, thick plate cutting has high requirements for laser cutting machines. Whether it is cutting speed or cutting section, it is a test for the technology of laser cutting machine manufacturers.
What problems will you encounter in the process of cutting thick plates?
1. Thick plate perforation
Laser perforation is the first step before cutting. The thicker the plate, the longer the perforation time, and the larger the proportion of perforation time. Therefore, in order to improve the cutting efficiency, many laser manufacturers will make improvements in the perforation time to achieve rapid perforation, but there will also be holes burst in the operation process, which is caused by the use of high-power cutting machine and high speed. On the contrary, the use of low-power pulse perforation will lead to long cutting time, power reduction and high unit cost.
2. Cutting section quality problems
The difficulty of laser cutting thick plates is much higher than that of thin plates, and the beauty of the section is more obvious than that of thin plates. Therefore, for the cutting section often encountered in the processing of medium and heavy plates, the cutting is not only the quality of the finished product is questioned, but also accompanied by overburning and serious slag sticking, so that the processing value of the laser cutting machine cannot be fully reflected.
3. Stability of whole plate batch processing
In the whole plate processing of metal plates, sometimes the phenomenon of poor processing in local areas will occur randomly, even when the processing machine is in good condition. Dealing with local processing problems will also affect the progress of the whole processing.
