1. metal laser cutting machine Adjust the focus position
The laser power density affects the cutting speed, and the relative position of the focal point and the workpiece surface
is very important to the cutting quality after knowing what kind of focal length lens is used. Due to the high power density
at the focal point, the head laser cutting, in most cases, the cutting focus position is just at the workpiece surface, or slightly below the surface.
In the whole cutting process, the relative position of focus and workpiece is constant,
which is an important condition to obtain stable cutting quality. Sometimes, the FR4 laser cutting,
lens work due to poor cooling and heat resulting in a change in focal length, which requires timely adjustment of the focus position.
2. metal laser cutting machine Gas pressure
The type and pressure of gas have great influence on the cutting speed of laser cutting machine.
For most of the metal laser cutting is the use of active gas as long as oxygen, Maanshan laser cutting,
forming and hot metal oxidation exothermic reaction, TWS laser cutting, this part of the additional heat can speed up the cutting speed of 1/3 ~ 1/2.
