Stainless steel cutting machine: why you can’t get the ideal cutting effect?

Stainless steel cutting machine: Why you can’t get the ideal cutting effect?

Stainless steel is a common metal material in life. Cutting is definitely used to process stainless steel raw materials. At present, the most suitable way to cut stainless steel is fiber laser cutting. Stainless steel cutting machine is to use a focused high-power density laser beam to irradiate the workpiece to melt the irradiated material, and at the same time to blow off the molten material with the coaxial high-speed gas, so as to achieve the purpose of cutting the workpiece.

Compared with traditional cutting methods, metal stainless steel laser cutting machine has simpler operation requirements, quicker hands-on, better processing compatibility, and certain advantages in speed. Therefore, it is believed that in the future selection of cutting methods, fiber laser stainless steel cutting machine will be the demand of the public.

Speaking of stainless steel cutting, when cutting stainless steel, you will always encounter unsatisfactory cutting results. I don’t know how to adjust it in the face of many parameters? Now, let’s analyze the adjustment and analysis of the laser cutting effect of stainless steel.

Factors affecting the laser cutting effect of stainless steel include: cutting height, stainless steel cutting machine nozzle model, focus position, cutting power, cutting duty cycle, laser machine cutting air pressure and cutting speed. The hardware conditions include: stainless steel laser cutter protective lens, gas purity, plate quality, focusing lens and collimating lens.

Stainless Steel Cutting Machine Work tips :

1Check the relevant stainless steel cutting machineparameters and hardware conditions

Adjust related parameters. When cutting stainless steel, the cutting height should be adjusted to between 0.8mm and 1.2mm. If the actual cutting height is inaccurate, calibration is required. Choose the appropriate nozzle size and model according to the thickness of the stainless steel, and check whether the nozzle of the stainless steel cutting machine cutting head is damaged and whether the roundness is normal before cutting. Finally, adjust the cutting parameters.

Check the stainless steel cutting machine hardware conditions. It is recommended to check the optical center with a cutting nozzle with a diameter of 1.0. When checking the optical center, the focus should be between -1 to 1. In this way, the light spot is small and easy to observe. Check whether the protective lens is clean. Stainless steel cutting machine requires no water, no oil and no slag spots during cutting process. Sometimes the protective lens may be fogged due to weather or the auxiliary air is too cold.

2. Problems and solutions encountered in laser cutting of stainless steel

There is dregs during cutting, if only the corners are dregs, consider rounding the corners first. In terms of parameters, you can reduce the focus and increase the air pressure. If there is hard slag on the whole, it is necessary to reduce the focus, increase the air pressure, and increase the cutting nozzle, but the focus is too low or the air pressure is too high, which will cause the section to be stratified and rough. If the granular soft slag is hung as a whole, the stainless steel cutting machine cutting speed can be appropriately increased or the cutting power can be reduced. Cut the slag on the side of the stainless steel that is about to end, and check whether the gas supply is insufficient and the gas flow cannot keep up.

When stainless steel cutting machine working, the section of the thin plate is not bright enough, and the section of the thick plate is rough. If you want to cut the section to be bright, you must first have a good surface without rust, no paint, and no oxide film, and secondly, the oxygen purity must be at least 99.5% or more. When cutting, you need to use a small nozzle double layer 1.0 or 1.2. Cutting speed It needs to be faster than 2m/min, and the stainless steel cutting machine cutting air pressure should not be too high. If you want to cut the thick plate with good quality, you must first ensure the purity of the plate and gas, and secondly, the nozzle is selected. The larger the aperture, the better the quality of the section, but at the same time the taper of the section will be greater.
