Laser cutting machine is an efficient and high-precision cutting equipment, which is widely used in metal processing, automobile manufacturing, aerospace and other fields. When cutting with a laser cutting machine, how to accurately position the laser beam focus is a very important step, which determines the cutting quality and accuracy. The following describes several common cutting positioning methods.
1. Zero focal length: Zero focal length means that the laser beam is focused on the surface of the workpiece, so that its focus coincides with the surface of the workpiece. This focus positioning method is suitable for cutting thin materials, such as sheet metal, stainless steel and other sheet materials, but the width of the cutting seam is larger.
2. Positive focal length: Positive focal length means that the laser beam is focused at a certain distance below the surface of the workpiece, so that its focus is located inside the workpiece. This focus positioning method is suitable for thicker materials, such as steel plate, aluminum plate and other thick plate materials, and the cutting seam width is smaller in this way.
3. Negative focal length: Negative focal length means that the laser beam is focused at a certain distance above the surface of the workpiece, so that its focus is above the workpiece. This focus positioning method is suitable for thinner materials, such as plastic, wood and other non-metallic materials.
Laser cutting machine focus automatic tracking system is mainly by detecting the distance between the focusing mirror and the workpiece surface, and using the motion controller to achieve high-speed shift of the focusing mirror, maintain the laser focus and the workpiece surface relative position, to achieve real-time tracking and compensation in the cutting process, so that the cutting process is more accurate.
In short, when cutting with a laser cutting machine, choosing the right focus positioning method and control system can make the cutting process more accurate and efficient.
