What should we pay attention to when cutting thick steel plate with CNC flame?

CNC flame cutting machine, this cutting machine at present, is the use of more machines and equipment, in the cutting of steel plate in this aspect, because it has some advantages.

However, everything has its pros and cons, and the same is true for CNC flame cutting machines. It is in the process of cutting, if used or handled improperly, then there will be a variety of cutting problems, or produce cutting defects, thus affecting the final cutting quality.

1. Forging cutting
The main problem of cutting forgings is that cutting is easy to interrupt, so that the ergonomic efficiency and cutting quality decline.
Therefore, before cutting, we should completely remove the oxide scale on the surface of the cutting area, so as to avoid the problem.

2. Cutting thick steel plate
For the cutting of thick steel plate, the main problem is that the combustion direction of the thickness of the steel plate is inconsistent at the starting position of the cutting, which makes the defect problem appear at the beginning of the workpiece cutting. Therefore, the methods and measures we can take are:
Method and measure one: using circular arc feed, which can increase the length of the lead line, so as to avoid direct cut.
Method and measure two: add a piece of steel plate at the entry point, close to the cut steel plate, there should be no gap, and then use the ignition rod to cut, so as to avoid problems and improve the utilization rate of the plate.
