The error of CNC flame cutting machine and CNC plasma cutting machine is different. The error of the CNC flame cutting machine is a lot of manual control factors, including flame adjustment, air pressure control, cutting speed control, etc. Besides, the surface of the steel plate before cutting The dirt is cleaned up and formed once at the time of cutting. Try not to repeat the cutting repeatedly. 

The factors that affect the quality of CNC flame cutting and cause dimensional errors in cutting are organized and analyzed as follows:

1. If the flatness of the board is not good, the size is easy to change after cutting;

2. For long strips with large length and width, use common edge cutting, cut the long edge first, and then cut the short head after the steel plate cools.

3. Due to the slow flame cutting speed and the long preheating time, the steel plate will absorb heat and cause thermal deformation, which can be solved according to the shape and experience of the part when preparing the CNC cutting program.

4. In the cutting process, the internal stress of the material will be released and the local internal stress will be released and redistributed with the removal of the material, which will cause the displacement and deformation of the steel plate and cause the cutting size to be out of tolerance.

According to the above factors that cause errors, I believe consumers can effectively prevent cutting errors during the use of CNC cutting machines!
