The cutting thickness of the laser cutting machine is 10mm.

When the laser cutting machine cuts 10mm thick plate, it is mainly because the increase of the thickness of the bai steel plate is easy to cause the decrease of the oxygen purity of the incision, which affects the temperature of the incision. The purity of the oxygen flow has a strong influence on the cutting process.

When the purity of oxygen stream decreases by 0. 9%, the combustion rate of iron and oxygen will decrease by 10%; when the purity decreases by 5%, the combustion rate will decrease by 37%.

The decrease of combustion rate will greatly reduce the energy input into the cutting seam during the combustion process, reduce the cutting speed, and increase the iron content in the liquid layer of the cutting surface, thus increasing the viscosity of the slag, resulting in difficulty in discharging the slag, so that serious slag hanging will appear in the lower part of the incision, making the quality of the incision unacceptable.

Comparison of commonly used cutting processes:

1. Laser cutting

Laser cutting is the use of focused high power density laser beam irradiation of the workpiece, so that the irradiated material is rapidly melted, vaporized, ablated or reached the ignition point, at the same time with the beam of high-speed airflow blowing off the molten material, so as to achieve the workpiece cut. Now generally use CO2 pulse laser, laser cutting is one of the thermal cutting methods.

2. Water cutting

Water cutting, also known as water knife, that is, high-pressure water jet cutting technology, is a machine that uses high-pressure water flow to cut. Under the control of the computer can arbitrarily carve the workpiece, and by the material texture influence is small. Water cutting is divided into no sand cutting and sand cutting two ways.

3. Plasma cutting

Plasma arc cutting is a processing method that uses the heat of high-temperature plasma arc to locally melt (and evaporate) the metal at the cut of the workpiece, and uses the momentum of high-speed plasma to exclude the molten metal to form a cut.

4. Line cutting

Wire cutting can be divided into fast wire cutting, middle wire cutting and slow wire cutting. The wire speed of fast-moving wire EDM is 6~12 m/s, and the electrode wire is moved back and forth at high speed, so the cutting accuracy is poor.

WEDM is a new technology developed in recent years, which realizes frequency conversion multiple cutting function on the basis of fast wire cutting. WEDM wire cutting speed is 0.2 m/s, the electrode wire to do low-speed unidirectional movement, cutting precision is very high.
