There are many ways to cut medium and thick plates, the most common way is to use fire, line and other ways to cut and process.
In the process of cutting, the common problem is that slag may hang on the lower edge, and cutting cracks may appear at the same time. Because some steel plates have good wear resistance, the cutting speed of medium and heavy plate cutting manufacturers is very slow.
In order to speed up cutting speed, preheating before cutting can not only increase cutting speed, but also avoid cutting cracks.
When using, we should pay attention to the maintenance of the medium and heavy plate CNC cutting machine. For the use of the medium and heavy plate CNC cutting machine, the protection is also very important. Of course, nowadays, this kind of equipment pays special attention to the protection and guarantee in this aspect when it is designed, so there are fewer and fewer accidents caused by the use of this kind of equipment, but the safety problem is no small matter.
There is also a very important problem is the correct wearing of work clothes. Generally, when operating the medium and heavy plate cutting machine, the staff will be asked to wear special work clothes and gloves to stop the operation. If you are lazy for a while or do not wear them according to the rules for other reasons, it is easy to form unnecessary injuries.
Before cutting the plate, if there are residual impurities in the plate, warpage will occur after cutting the plate, thus affecting the cutting quality. The treatment plan is to be able to stop cold straightening to improve the residual stress distribution on the steel plate and make its internal stress average, which can be handled well. In the process of plate cutting, the plate can only be cut after feeding and marking.
