The focusing lens is an important part of the laser cutting machine, and should be updated from time to time. Because of the film falling, dents, scratches and other phenomena that may occur after a long time of use, the function of the laser device will be greatly reduced. In order to better install the focusing lens, please pay attention to be below:
1) The convex surface of the lens of the laser cutting machine shall be upward and shall not be reversed.
2) Dirt or fingerprints are not allowed on the mirror surface.
3) The steel ruler shall be inserted into the clamping groove and slightly rotated and tightened, and the edge of the steel ruler shall not touch the part of the lens.
4) Shake gently, and the lens is not loose.
