The role of laser head nozzle in laser cutting

The nozzle laser head is easily consumed by the most commonly used fiber laser cutting machine, with the wide application of fiber laser cutting technology in the past few years, the development demand of the laser head nozzle. Nozzle type parallel, converging cone and three forms, the main form of the nozzle and the main form of the cutting quality of the nozzle size have a close relationship.

The first function is to protect the internal control lens of the laser head. In the process of laser cutting, especially when drilling, there is often slag sputtering, and the high-pressure ambient gas blown out by the laser head nozzle can block most of the sputtering objects of the enterprise and protect the lens from damage;

The second effect is to collect the capacitance signal, and transmit it to the signal processor through the Chinese ceramic ring. The signal processor sends a signal to the machine tool internal control research center. The machine tool control management center provides timely feedback based on the signal, and adjusts the vertical development of the laser head. The position of the direction, so as to keep the distance tracking of the laser head to the workpiece during the cutting process;

The third role is the high pressure that is attached to the inner shape of the gas to be cut through the piece to be cut, and the outlet of the nozzle. Nozzle outlet hole, higher formation pressure. Occurs by the cutting member, if the oxidation is cut off, after the high pressure oxygen through the nozzle, a part of the working surface is provided with the oxidation reaction heat, the cutting acceleration; high speed passes on the cutting surface, the cutting surface is far away from the slag, and the other part of the slag is kept properly. pressure to ensure a smooth cut.

WSX laser nozzle has fast cutting speed, good cutting surface finish, long life, excellent thermal conductivity, high strength and corrosion resistance; imported copper material is selected, which is different from ordinary red copper brass, with high sensitivity, solid and durable; fully automatic import Mechanical, computer-controlled one-time processing and molding, high precision, smooth inner wall; strict anti-oxidation process, bright copper color, can effectively prolong the use time.
