With the widespread popularity of laser cutting machines, the corresponding accessories are also gradually coming into view. Today, let's take a look at the focusing lens of laser cutting machines.

The focusing mirror of laser cutting machine is mainly divided into aspheric focusing mirror and spherical focusing mirror.

Aspheric focusing mirror: It is used as the focusing mirror in the optical fiber laser cutting machine. The basic material is fused quartz, and the antireflection film is coated on both sides. Based on the aspheric application, spherical aberration will not be introduced in the transmission wavefront and the limit diffraction performance can be achieved. The single aspherical lens can completely replace the traditional multiple spherical combination lenses.

Spherical focusing mirror: It is used as the focusing mirror in the optical fiber laser cutting machine. The basic material is fused quartz, and the antireflection film is coated on both sides. In order to reduce spherical aberration as much as possible, double piece combined spherical lenses are usually used.

After the original laser cutting machine focus lens is used for a long time in the cutting process, if there are dents, film drops, scratches and other phenomena, the cutting function of the laser equipment will be greatly reduced. If you want to give full play to the function of the laser cutting machine, you need to replace the focusing lens in time. How to install the focusing lens correctly?

Correct installation method of laser cutting machine focusing lens:

1. Put the protective film of the laser cutting machine focusing mirror in the heart of your hand, with the convex side of the lens facing upwards;

2. Pick up the focusing tube and carefully put it in the lens holder's hand to cover the entire lens;

3. Rotate both hands 180 degrees clockwise at the same time;

4. After the pressure lens is released, tighten the pressure lens nut with a small steel ruler;

5. Install the air jet cup on the focusing cylinder of the laser cutting machine;

There are also some matters to be noted during the installation process, as follows:

1. The convex surface of the lens of the laser cutting machine shall be upward and shall not be reversed;

2. No stains or fingerprints are 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.

The above is a small knowledge of laser cutting machine focusing lens, which can be easily understood by everyone. The actual operation needs more appropriate professionals to avoid mistakes and losses.
