Laser Light Path

The core component adjusts the curvature of the lens surface through water pressure, modifying the divergence angle of the laser beam, and thereby allowing for adjustment of the laser focus up and down movement.

Additionally, it compensates for changes in focus that occur as a result of varying spot diameters at different working positions of the machine.

Laser Generator

• The high-quality laser beam, laser energy can achieve stepless regulation
• Using RF technology, low gas loss rate

Fiber Laser Cutting Head

Focus Position

In practical applications, the height of the focus varies with the material and the cutting machine.

Focus position selection

In laser cutting, the position of the laser focus greatly impacts the quality of the surface finish of the cut parts, and different materials have different focus requirements.

For instance, when cutting carbon steel, the focus should be on the top surface of the plate; when cutting stainless steel, the focus should be approximately halfway through the thickness of the plate; when cutting aluminum alloy, the focus should be close to the bottom surface of the plate.
