1、 The metal conditioning head laser tube has two simple air leakage conditions
1. The raw material of conditioning head laser tube should be valvable data, which is very expensive. Laser tube manufacturers in our country often use stainless steel data, which leads to great difference between expansion coefficient of metal conditioning head and glass expansion coefficient, great change of temperature in one year, and simple air leakage at the bonding point between metal conditioning head and glass
2. This manufacturing method of metal conditioning head laser tube is imitated that of American laser tube. However, due to the machining ability of our country is not as good as that of the United States, the manufacturing of metal conditioning head is not careful, and many unqualified metal conditioning head is applied to laser tube, resulting in gas leakage of laser tube.
2、 The spot of laser tube of metal conditioning head is changed simply. The metal conditioning head can be adjusted. In the process of reproducing laser tube, if the spot is not good, adjust the metal conditioning head. In this way, it is very convenient to produce laser tube. However, everything has advantages and disadvantages. The disadvantage is that after the spot is adjusted, the spot of laser tube will change in the process of application, leading to poor cutting and carving effect.
In view of the above shortcomings of the traditional SMD laser tube, it is very difficult to glue the lens in the production process of the laser tube (precisely because of this difficulty, many laser tube manufacturers in China choose metal conditioning head). However, once glued, the spot is in the best condition. In the process of using the laser tube, the spot will not change, because we use the beauty of the laser tube China's vacuum glue will not leak.
