How to maintain laser cutting composite focusing lens

The focusing lens of a laser cutting machine is a relatively precise optical component and a vulnerable component. Its cleanliness directly affects the processing performance and quality of the laser cutting machine. So, regular maintenance of the focusing lens is very necessary. The correct operation process for maintaining the focusing lens of a laser cutting machine is as follows:

1. Remove the focusing lens from the frame: Loosen the fastening screws and sequentially remove the air nozzle and lens barrel; First, use a balloon to blow away the dust on the surface of the lens;

If it is necessary to clean the lens, only laboratory grade paper cotton balls can be used, dipped in an appropriate amount of acetone or high proof alcohol, and gently rotated clockwise from the center of the lens towards the edge. When necessary, both sides of the laser cutting machine lens need to be cleaned, and the cleaning should be done carefully and meticulously;

3. Install the lens barrel and air nozzle, adjust the focal length, tighten the fastening screws, and make sure to keep the convex surface downward when installing the focusing lens

The focusing lens of a laser cutting machine is a consumable item. If it still cannot achieve a high level of cleanliness after multiple cleaning cycles, it should be replaced to ensure the processing efficiency of the laser cutting machine and avoid delaying production.
