A laser engraver is a common tool used for engraving and cutting on a variety of materials. Before using a laser engraver, it is very important to understand how it works and what to look for.

First, we need to understand how a laser engraver works. Laser engraving machines have two main working principles: dot matrix engraving and vector cutting.

1. Dot-matrix engraving

Dot matrix engraving is similar to high-resolution dot matrix printing.laserpecker 2 laser engraver The laser head oscillates from side to side, engraving a line consisting of a series of dots at a time. The laser head then moves up and down, engraving multiple lines at the same time, culminating in a full page of images or text. Scanned graphics, text and vectorized graphics can all be engraved using dot-matrix engraving.

2. Vector Cutting

Vector cutting is different from dot matrix engraving. Vector cutting is achieved by engraving the outer contour of the text. We usually use this mode to cut materials such as wood, acrylic, paper, etc.laser pecker 4 We can also perform marking operations on the surface of various materials.

In addition to understanding the working principle, we also need to understand the following three concepts: laser engraving speed, laser engraving intensity and spot size.

3. Laser engraving speed

Laser engraving speed refers to the speed at which the laser head moves, usually measured in inches per second (IPS). Higher speed means higher productivity. Speed is also used to control the depth of cut.laser pecker pro For a given laser intensity, the slower the speed, the greater the depth of laser cutting or laser engraving. We can adjust the speed using the engraver panel or through the print driver program of the computer. The adjustment range is from 1% to 100%, with each adjustment being 1%. The advanced motion control system allows the laser engraver to maintain super fine engraving quality even at high speed.

4. Laser engraving intensity

The intensity of laser engraving refers to the strength of the laser light hitting the surface of the material. For a given engraving speed, the greater the intensity, the greater the depth of cut or engraving. We can adjust the intensity using the engraver's panel or through the computer's operating software. The adjustment range is from 1% to 100%, with each adjustment being 1%. The higher the intensity, the lower the speed and the deeper the cutting depth.

5. Spot size

The laser beam spot size can be adjusted with lenses of different focal lengths. Smaller spot lenses are good for high resolution engraving, while larger spot lenses are good for lower resolution engraving, but are also best for vector cutting.

When using the laser engraving machine, you also need to pay attention to the following points:

1. turn on and off the machine strictly according to the operation sequence.

2. prohibit unqualified personnel from operating and repairing the machine.

3. in the process of machine tool work, it is strictly prohibited to enter the worktable, to ensure the safety of man and machine; operators in the event of a dangerous situation, you must focus your attention, as soon as possible, press the "emergency stop" button. 4.

4. Adjustment of the optical path of the machine and the cutting head in the following mode must be carried out in accordance with the correct sequence of operation to ensure the safety of man and machine. 5.

5. Every time before starting the machine must return to the reference point, check and clean the focusing mirror, calibrate the coaxiality of the beam nozzle, open the cutting auxiliary gas, the pressure in the bottle should not be too large, less than 1Mpa.

By understanding the working principle and precautions of the laser engraving machine, we can better use and maintain this equipment to improve productivity and safety.
