How to change the laser cutting machine can not cut through the situation

The reasons why the laser cutting machine does not cut through the workpiece include but are not limited to the following:

The laser power is insufficient. If the power setting of the device is low, or the laser generator of the device itself is aging and failing, resulting in the output power not reaching the cutting requirements, the material will not be cut through.

Cutting speed is too fast. The cutting speed and laser power should match, the speed is too fast, the time of laser action on the material is too short, the energy is too late to fully act, and the material can not be cut through.

The focus is out of place. The focus position has a great impact on the cutting effect, if the focus is not in the right cutting position, such as the focus is too high or too low, the laser energy can not be well gathered at the cutting site, resulting in a reduction in cutting ability.

Material problem. The thickness of the material to be cut, material characteristics, etc., will also have an impact. If the material is too thick, beyond the cutting capacity of the equipment, or the material has a high reflectivity of the laser and a low absorption rate, such as some high-reflectivity metals, it will lead to impenetrable cutting.

Auxiliary gas problem. The role of the auxiliary gas is to blow away the slag and protect the cutting surface. If the gas pressure is insufficient or the gas type is not appropriate, the slag can not be effectively blown away, which will affect the continuous cutting of the laser, resulting in impenetrable cutting.

In order to reduce the cutting impenetrability of laser cutting machine, you can start from the following aspects:

Equipment and parameters

Regular maintenance and inspection equipment: regularly clean and maintain the laser cutting machine, check the laser generator, optical path system, cutting head and auxiliary gas system and other components. Ensure the normal operation of the equipment, such as timely replacement of aging or damaged optical lenses, to ensure the transmission efficiency and focusing effect of the laser, so as to ensure the cutting power.

Optimize cutting parameters: Adjust laser power, cutting speed, focus position and auxiliary gas pressure according to material type, thickness and other factors.

Materials and processes

Strict screening of materials. Ensure that the quality of the material meets the cutting requirements, and for some high-reflectivity materials, the surface treatment can be carried out in advance to increase the absorption rate of the material to the laser. At the same time, the power is increased.

Use appropriate processes. A reasonable arrangement of the cutting sequence, such as from thin to thick or from simple shape to complex shape, helps to keep the equipment stable.

People and management

Strengthen personnel training. When the operator finds that the cutting is not transparent, he knows how to correctly adjust the parameters or suspend the cutting to check the equipment.

Establish a quality control system. Strengthen the quality control in the cutting process, set up inspection points, and carry out sampling or full inspection of the workpiece after cutting.
