Cutting round holes with a laser cutter requires some skill. Let the laser engineer on the problem of cutting round holes to analyze the reasons and matters needing attention.

More and more enterprises began to apply laser cutting round hole, because of the flexibility and efficiency of laser processing. machine 100w fiber laser air range 90 meters per minute speed is enough to meet the needs of many sheet metal processing plants for high speed, in addition, laser processing of the round hole section is more smooth, the diameter of the round hole can also be infinitely modified to meet the diverse needs of the factory.

However, using fiber laser machinery to process round holes is not very simple, but requires some skills. Let the laser engineers on cutting round hole problems to analyze the reasons and matters needing attention.

The blowing pressure is not suitable

In the process of blowing, when the pressure is too small, there will be edge scraping slag, carbonization phenomenon, too much pressure and easy to burst. So this requires process proofing division and machine perfect cooperation, with experience to choose the right air pressure, so as to cut the round hole more full.

The hole is too small

Laser cutting machine cutting round hole the best scheme is round hole ratio 1:1, that is to say, the aperture and plate thickness ratio of 1:1, of course, this ratio, that is to say, the larger the aperture, cutting high-quality round hole is easier. Otherwise, when the energy of the fiber laser cutting machine is insufficient, the cutting hole is prone to point breakpoint residue and circular hole is not round.

Servo motor parameters are wrong

Circular holes sometimes appear elliptic or irregular, which is related to the mismatching of X\Y axis motion, and the direct cause of the mismatching of X\Y axis motion is the improper adjustment of servo motor parameters. So cutting hole quality, servo motor also has certain requirements.

Guide rail and lead screw precision error

If the servo motor parameter error affects the cutting quality, then the guide rail and screw precision error will directly lead to the round hole precision is not expected. This is related to the strength of laser cutting machine manufacturers, usually, some small factories will deceive customers that laser cutting machine accuracy can reach 0.1mm, but in fact, in the actual operation process, will make laser drilling quality and effect are not good, affect the added value of products. So it is necessary to choose high quality and large brand laser cutting machine.

All these parameters are used to identify whether the precision, speed and other parameters of cutting round holes meet the requirements of the standard, which is enough to identify whether the quality of the laser cutting machine purchased is qualified. Therefore, customers must keep their eyes wide open in the process of buying laser cutting machines.
