Reasons and solutions for the decline in cutting accuracy of laser cutting machines

In modern manufacturing, laser cutting machines have become indispensable equipment in many industries with their high precision, high efficiency and non-contact processing. However, as time goes by, laser cutting machines may have problems with reduced cutting accuracy, which not only affects product quality, but may also increase production costs. This article will explore in depth the reasons for the decline in cutting accuracy of laser cutting machines and provide a series of effective solutions to help you easily cope with this challenge.

There are many manifestations of reduced cutting accuracy of laser cutting machines, such as uneven cutting edges and increased dimensional deviations. These problems are directly related to the stability of the laser beam, the mechanical accuracy of the equipment, and the skill level of the operator. When the cutting accuracy of the laser cutting machine cannot meet the production requirements, we need to deeply analyze the reasons behind it and take corresponding solutions.

‌1. The main reasons for the decline in cutting accuracy‌

‌Equipment aging and wear‌: After long-term use, the key components of the laser cutting machine, such as the laser, guide rail, and motor, will gradually age or wear, resulting in reduced equipment accuracy. For example, the wear of the guide rail will affect the movement accuracy of the cutting head, thereby affecting the cutting quality.

‌Focus position deviation‌: The focal position is an important factor affecting the accuracy of laser cutting. The focus position deviation will cause the point of action of the laser beam on the material to change, thus affecting the cutting accuracy.

‌Improper distance between the nozzle and the workpiece‌: The distance between the nozzle and the workpiece that is too far or too close will affect the cutting effect. If the distance is too far, the laser energy will be dispersed, and if the distance is too close, the cutting accuracy may be affected due to the large heat-affected zone.

‌Improper operation and unreasonable parameter setting‌: The skill level of the operator directly affects the cutting accuracy of the equipment. At the same time, unreasonable settings of parameters such as cutting speed, power, and frequency will also lead to reduced cutting accuracy.

‌II. Effective methods to solve the reduction of cutting accuracy‌

‌Regular maintenance and maintenance‌: Regularly maintain and maintain the laser cutting machine, including cleaning the lens, checking the position of the focusing mirror, replacing aging laser components, etc., to ensure the mechanical accuracy of the equipment and the stability of the laser beam. At the same time, lubricate and check the wear of moving parts such as guide rails and motors, and replace severely worn parts in time.

‌Adjust the focal position and nozzle distance‌: Adjust the focal position to the optimal state according to the thickness and material of the actual cutting material. At the same time, adjust the distance between the nozzle and the workpiece according to the cutting requirements to ensure that the laser energy can fully act on the cutting material and improve the cutting accuracy.

Optimize cutting parameter settings: According to the characteristics of the cutting material and the cutting requirements, reasonably set the cutting speed, power, frequency and other parameters. Avoid blindly increasing the cutting speed or reducing the power to ensure that the laser cutting machine works in a stable and efficient state.

Strengthen operation training: Provide professional training for operators to familiarize them with the working principle, operation method and maintenance knowledge of the laser cutting machine. Improve the skill level of operators and reduce the reduction of cutting accuracy caused by improper operation.

Upgrade equipment and technology: With the continuous development of laser technology, new equipment and technologies are constantly emerging. Consider upgrading existing equipment or introducing new technologies to improve cutting accuracy and production efficiency. For example, adopt more advanced laser technology, more precise guide rail system, etc.

In summary, the problem of reduced cutting accuracy of laser cutting machines can be effectively solved through regular maintenance and maintenance, adjusting the focus position and nozzle distance, optimizing cutting parameter settings, strengthening operation training and upgrading equipment and technology. As an important equipment in the manufacturing industry, the cutting accuracy of the laser cutting machine directly affects the quality and production cost of the product. Therefore, we should pay attention to the maintenance and accuracy improvement of the laser cutting machine to ensure that the equipment is always in the best working condition and provide strong guarantee for the production and development of the enterprise.
