Micron-level machining accuracy 2024: Discover the endless possibilities of ultra-high-precision laser cutting processes

With the rapid development of science and technology, micron-level machining accuracy has been more and more widely used in various fields, especially in high-end manufacturing industries such as aerospace, electronic products, medical equipment, etc., with higher and higher requirements for machining accuracy. In 2024, it is expected that the micron-level machining accuracy will reach a new height, making the application of laser cutting technology enter a new stage.

1.        What is the micron-scale laser cutting process

The basic principle of micron-scale laser cutting is to use a highly focused laser beam to irradiate the material, so that the material is quickly heated up locally and achieve precise material removal or cutting. Its key technologies mainly include:

1.1          High-power lasers:

Micron-level laser cutting requires the use of pulsed lasers with peak power of up to kilowatts or even 10,000 watts, and commonly used lasers are silicon carbide (SiC) lasers, fiber lasers, etc. A laser beam with a high power density can quickly heat the material to a melting or vaporization temperature.

1.2        Precision Focusing Optical System:

By using a numerically controlled focusing mechanism, the laser can be precisely focused in the range of 0.1 microns, and a very small spot can be obtained, enabling high-precision processing.

1.3       High-precision digital control system:

The numerical control system can accurately control the position of the laser head and the beam parameters, and process according to the set path and process parameters to realize the cutting of complex shapes.

Auxiliary processing gas supply system In order to protect and guide the laser beam, inert gases such as helium and argon are often used to purge the processing area to avoid negative effects on processing quality such as oxidation.

1.4       Process Detection & Feedback System:

High-speed cameras, thermal imagers and other equipment are used to monitor the processing process, and feedback and adjust the laser parameters to achieve closed-loop control, so as to ensure the processing quality.

Micron-level laser cutting technology combines optics, mechatronics, digitalization and intelligent technology, so that laser processing has entered a new stage of high precision.

2.      The importance of micron-level machining accuracy

Micron-level machining accuracy is an indispensable key technology for many high-tech products, which is directly related to the performance and quality of products. The aerospace field has extremely high requirements for material processing accuracy, such as jet engine blades, rocket engine nozzles, etc., which require micron-level or even higher processing accuracy to ensure the safety and reliability of products. Surgical instruments, mechanical hearts, and artificial joints in the medical industry also require high manufacturing precision.

With the development of science and technology, micron-level processing will be widely used in more fields in the future, opening up more possibilities for new products. Achieving higher precision means that smaller, more complex parts can be manufactured, which can lead to a boom in new high-tech industries such as nanotechnology and ultra-high-speed computing.

3.      2024 micron-level machining precision technology development forecast

Experts predict that by 2024, the accuracy of micron-level machining will be significantly improved, and the cutting accuracy can reach 0.1 microns (0.001mm/0.0254inch) or less. This is mainly due to the following technological advancements:

The working accuracy and repeatability of the laser cutting machine have been greatly improved. With the optimization of hardware such as positioning system and transmission system, the working accuracy of the cutting machine can reach the sub-micron level.

More precise application of laser beam positioning technology. The imaging optical system and advanced beam modulation device can achieve nanoscale laser beam positioning.

Application of advanced process monitoring technology. High-speed cameras, sensors and other equipment are used to monitor and feedback the cutting process in real time to ensure processing quality.

The use of intelligent software. Intelligent algorithms can accurately calculate the ideal cutting path and parameters, greatly improving accuracy.

The use of new materials and coated optics. New materials such as silicon carbide lenses can handle higher power and more precise laser beams.
