Both rely on mechanical machining accuracy to ensure beam concentricity. However, the focusing lens is used for a long time, so that the situation that the light spot deviates from the theoretical focal position easily occurs. Which in turn can lead to poor quality cut workpieces.
For adjustment, and considering the structural simplicity and low cost, the laser cutting heads of most manufacturers in China adopt manual centering structures, and the manual centering structures can be roughly divided into two types according to the difference of the used elements:
1. the manual adjusting screws are arranged in a plane in a top-to-top manner, and a group is arranged in each of X and Y directions. The principle of the adjusting mode is that the adjusting screw is used for positioning the position of the focusing lens barrel, one end of the adjusting screw in the X or Y direction is loosened for a certain distance, and the other end is screwed for a certain distance. This approach is intuitive, but because the focusing lens group is sealed inside the laser cutting head, it is not easy to replace the focusing lens and protect the lens. In addition, the adjusting screw is often rotated, so that dust is easily introduced.
2. Another way is to position the focusing barrel with a tension spring and an adjusting screw. The drawer type structure is adopted in the mode, so that the problem that the lenses are not easy to replace is avoided. However, the adjusting screw is also required to be frequently screwed, dust is easily introduced, and thus the adjusting screw thread may be blocked. Or after long-term use, water vapor or oil easily enters the cavity to pollute the lens.
