The ceramic ring is mounted on the cutting head, above the nozzle and below the sensor (see picture below). It is responsible for transmitting and collecting the cutting signal emitted by the nozzle to prevent the nozzle from colliding with the plate during operation and damaging other valuable parts of the cutting head. It has the effect of high temperature resistance and anti-deformation.

How to choose the right laser nozzle for laser cutting 1. Regarding the single-layer or double-layer of the nozzle, the single-layer laser nozzle is used for melting and cutting, that is, nitrogen is used as the auxiliary gas, and the single-layer laser nozzle is used for cutting stainless steel and aluminum plates. Double-layer laser nozzles are generally used for oxidation cutting, that is, using oxygen as auxiliary gas to cut carbon steel with double-layer laser nozzles.

Because the laser marking machine relies on the cooperation of X and Y vibration deflection, the light is reflected to the work surface for precise engraving. The control of the galvanometer is open-loop controlled by the computer. Therefore, the requirement must be linear, that is, there is a linear relationship between the input signal and the deflection angle. Because the galvanometer is a fast and precise machine, it is required that the acceleration be as large as possible from one working state to another, so that the marking time is infinitely small.

The key accessories of fiber laser cutting machine are lasers, motors, automatic control systems, laser cutting heads, laser lenses, etc.
