Steel Plate Numerical Control Flame Cutting Process

Steel plates cutting and cutting equipment mainly includes CNC flame cutting machine, CNC plasma cutting machine, straight cutting machine, semi-automatic cutting machine, etc.

Cutting Operation Process

When performing automatic cutting, the distance between the two ends of the steel plate and the guide rail should be adjusted within 5mm from the hanging steel plate to the gas cutting platform. When performing semi-automatic cutting, the guide rail should be placed on the plane of the cut steel plate, and then the cutter should be lightly placed on the guide rail. The side with the torch is oriented to the operator, and the cutting tip is selected according to the thickness of the steel plate to adjust the cutting straightness and the cutting speed.
According to the different automatic cutting and semi-automatic cutting methods, adjust the distance of each cutting gun, determine the rear drag, and consider the slit compensation; in the cutting process, the size and direction of the cutting angle of the cutting torch are mainly determined by the thickness of the steel plate, the cutting nozzle The relationship between the inclination angle and the thickness of the cutting piece and the cutting allowance are shown in the following table:
Relationship between the inclination of the cutting nozzle and the thickness of the cutting piece
 

Cutting thickness mm	<10	≥10
Inclination direction	Backward	vertical
Tilt angle	10°-15°	0°

Steel plate cutting allowance

Cutting method	Material thicknessmm	Slot width retention (mm)
Gas cutting	≤10	1~2
Gas cutting	10~20	2.5
Gas cutting	20~40	3
Gas cutting	over 40	4
