Hello everyone, your little sister is online, today I will tell you about the precautions for cutting circular holes on stainless steel laser cutting machines. Let ’s take a look together! Let ’s start the lecture!

More and more companies use lasers to cut round holes because of the flexibility and efficiency of laser processing methods. The circular hole section of laser processing is more lubricated, and the diameter of the circular hole can be infinitely modified to meet the diverse needs of the factory.


However, machining circular holes with a laser cutting machine is not very simple, but requires some skills. Let the laser engineer analyze the reasons and precautions for the problem of cutting round holes.

Insufficient air pressure

During the blowing process, when the air pressure is too small, the phenomenon of marginal slag scraping and charring will appear. If the pressure is too large, the hole will simply burst. So this requires the perfect cooperation between the process proofer and the machine, based on the experience to select the appropriate air pressure, and then make the round hole cut fuller.

Round hole is too small

The best plan for laser cutting machine to cut round holes is 1: 1 share of round holes, which means that the share of aperture and plate thickness is 1: 1. Of course, this share means that the larger the hole size, the better the quality of the cut. Round holes are getting simpler. Otherwise, when the energy of the fiber laser cutting machine is lacking, the small holes in the cutting simply leave the breakpoints and the round holes are not round.

Incorrect servo motor parameters

The round hole sometimes shows an ellipse or an irregular phenomenon. This is related to the mismatch of the X \ Y axis movement, and the direct reason for the mismatch of the X \ Y axis movement is the inappropriate adjustment of the servo motor parameters. Therefore, the quality of the cutting circular hole also has certain requirements for the servo motor.

Guide and lead screw accuracy errors

If the servo motor parameter error affects the cutting quality, the accuracy of the guide rail and screw will also directly cause the accuracy of the round hole to fall short of expectations. This is related to the strength of the laser cutting machine manufacturer. In practice, the quality and function of laser drilling will be poor, which will affect the added value of the product. Therefore, it is often necessary to choose high-quality and large-brand laser cutting machines.

All these parameters are used to identify whether the accuracy, speed and other parameters of the cutting circular hole meet the requirements of the specification, which are sufficient to identify whether the quality of the laser cutting machine purchased is acceptable. Therefore, customers must keep their eyes wide open in the process of purchasing laser cutting machines.
