Installation method and precautions of focusing lens of laser cutting machine

2020-09-22 18:34:31

After the focusing lens of the laser cutting machine is used for a long time, if there are phenomena such as film drop, dents, scratches, etc., the function of the laser equipment will be greatly reduced. If you want to perform the function of the laser cutting machine normally, you need to replace the new lens in time. So, how should we install the focusing lens correctly?

Laser cutting machine focusing lens: there are spherical focusing lens and aspheric focusing lens

Spherical focusing lens:
The focusing mirror used in the fiber laser optical system, the base material is fused silica material, with antireflection coating on both sides. In order to reduce spherical aberration as much as possible, it is recommended to use two-piece combined spherical lenses.




Aspherical focusing lens:
The focusing lens used in the fiber laser optical system, the base material is fused silica material, the double-sided antireflection coating is coated, based on the aspheric surface application, it will not introduce spherical aberration in the transmission wavefront and can reach the limit diffraction performance. The spherical lens can completely replace the traditional multi-piece spherical combined lens.

Installation method of focusing lens of laser cutting machine:
1. Put the protective film of the focusing lens of the laser cutting machine in the palm of your hand, with the convex side of the lens facing up
2. Take the focusing tube and place it carefully in the hand where the lens is, covering the entire lens
3. Rotate the left and right hands 180 degrees clockwise at the same time
4. After releasing the lens, tighten the lens nut with a small steel ruler
5. Install the air jet cup on the focusing tube of the laser cutting machine

Precautions for focusing lens of laser cutting machine:
1. The convex surface of the laser cutting machine lens is upward and cannot be reversed
2. No smudges or fingerprints on the mirror surface
3. Insert the steel ruler into the card slot, turn it lightly to tighten, and the edge of the steel ruler can not touch the part of the lens
4. Shake gently, the lens will not loosen

The above is Carmanhaas cutting lens factory briefly introduced the installation method and precautions of the focusing lens of laser cutting machine
