Laser cutting is realized by applying the high power density energy generated by focusing the laser. Under computer control, the laser processing head and the material to be processed according to the pre-drawn graphics for continuous relative motion puncturing, so that the object will be processed into the desired shape.
Laser cutting process is an invisible beam of light instead of the traditional mechanical knife, with high precision, fast cutting, not limited to the cutting pattern limitations, automatic layout to save materials, smooth incision, low processing costs and other characteristics, will gradually improve or replace in the traditional metal cutting process equipment.
Metal laser cutting machine in the long-term use of the process there are some more or less loss, such as cutting speed slows down, precision deterioration and other issues. So, what are the causes of metal laser cutting machine cutting ability to decline and preventive measures?
1.Causes of metal laser cutting machine cutting capacity decline
Fiber metal laser cutting machine in a long time after the use of laser power will attenuate the decline, which will directly affect the performance of cutting. Laser cutting speed and laser power has a direct relationship, the greater the power, the higher the cutting speed.
The focal point position affects the cutting progress, the diameter of the focal spot should be as small as possible in order to produce a narrow slit. If the cutting performance decreases, the focus position can be adjusted. The distance between the workpiece and the nozzle also affects the cutting effect, the distance is too far will cause energy waste, the distance is too close, it will affect the dispersion of spatter cutting products. In addition, improper operation, long time load production, long time without maintenance, etc. will lead to fiber laser cutting machine equipment performance degradation, cutting effect greatly reduced.
2.Preventive measures to reduce the cutting capacity of metal laser cutting machine
Comply with the safe operation procedures of the cutting machine. Strictly in accordance with the laser startup procedures to start the laser, dimming, test machine. Fiber metal laser cutting machine should be operated by a person, the operator must be trained, familiar with the cutting software, equipment structure, performance, master the operating system knowledge. It is very important to correctly implement the line switching sequence, familiar with the various switch panel buttons, the correct operation of the fiber laser cutting machine operation and so on.
When the equipment starts the operator shall not leave the post without authorization or entrust someone to take care of, such as indeed need to leave should stop or cut off the power switch. When abnormalities are found in the process, the machine should be stopped immediately, troubleshooting or reported to the competent personnel.
Focus on the maintenance of fiber metal laser cutting machine, fiber metal laser cutting machine processing time, many parts will have wear and tear, which will lead to a decline in processing performance. For wearing parts, they should be replaced frequently; optical components should be wiped clean after use to maintain cleanliness; bearings should be oiled regularly to maintain drive flexibility and processing accuracy.
