Ceramic ring - an important part of the cutting head of the fiber laser cutting machine
Fiber laser cutting machine has three major consumables, protective lens, nozzle, ceramic ring.
An important part of the cutting head of the fiber laser cutting machine is the ceramic ring, which is used to transmit the electrical signal collected by the nozzle of the laser head and stabilize the normal operation of the fiber laser cutting machine. The equipment we often encounter suddenly stops, the laser head hits the face and other failures are actually caused by the instability of the laser ceramic ring. Therefore, it is very important to choose a high-quality fiber laser cutting machine ceramic ring. Here I will introduce you how to choose a high-quality laser ceramic ring.
The laser ceramic ring consists of a ceramic body, stainless steel pieces and copper needles. The ceramic body is mainly used to maintain sufficient contact with the nozzle, thereby transmitting the electrical signal to the copper needle, which in turn transmits the electrical signal to the transmission line, and then the internal wire of the laser head transmits the signal to the controller.
After a period of use of the old laser ceramic rings on the market, the contact between the stainless steel parts and the copper needles is poor, or even the copper needles are broken, resulting in unstable or even no signal. The fiber laser cutting machine will also stop working due to these reasons, and even hit the working surface, causing losses to the user.
Signal stability: High-quality high-quality laser conductive silver glue ceramic ring is used to ensure tight connection with the stainless steel parts of the ceramic body, and at the same time to ensure the conductivity of the copper needles and the stainless steel parts.
Many laser ceramic rings on the market replace conductive silver glue with inferior glue. In a high temperature environment, the glue dissolves and the stainless steel parts become loose, which cannot guarantee the electrical conductivity of the product. The accident that the laser head hits the workpiece is easy to occur, causing great losses to the user.
High-quality stainless steel components ensure good concentricity after assembly with the ceramic body and are fully inspected. Therefore, when replacing the nozzle, the concentricity error between the two nozzles can be reduced, and if a high-quality nozzle is selected, the fiber laser cutting machine does not need to be reset when the nozzle is in contact with the nozzle. It greatly reduces the loss of working time and greatly improves the working efficiency of the fiber laser cutting machine.
Now the price of ceramic rings on the market is chaotic, the price of original ceramic rings is high, especially the imported ceramic rings, but there are also some domestically produced ones with fairly stable performance. Wanshunxing laser ceramic ring is made of imported ceramic material, which is precisely machined and has good brittleness and temperature adaptability.
