How does the plasma cutting machine process the slit slope of thick metal plates?
In the process of processing a thick metal plate with a plasma cutting machine, as the thickness of the workpiece increases, the lower the processing accuracy of the plasma cutting machine and the larger the cutting seam, the verticality of the cutting seam also decreases, and the slope appears. The cutting slope of plasma cutting machine is mainly affected by two aspects: the focal length and focal position of the processing lens.
The slit width will vary depending on the surface of the processed material’s light-gathering characteristics and focus setting accuracy.
Influence of machining lens distance on slope
The shorter the focal length of the lens, the smaller the diameter of the light spot, and the smaller the width and slope of the upper slit.
The focus position is the distance from the laser focus to the surface of the workpiece, which directly affects the roughness of the cut surface, the slope and width of the cut, and the adhesion of the molten residue.
