What does the cutting accuracy of metal laser cutting machine depend on?

As we all know, cutting accuracy is an important part of measuring the quality of laser cutting machine. In fact, the accuracy of metal laser cutting machine is not entirely determined by the equipment itself, but is composed of many factors. After analyzing the laser professional and technical personnel, we have the following major factors.

The shape of a laser beam

We all know that the laser beam is tapered, and the resulting gap is also tapered. In this case, the thickness of 0.3MM stainless steel will be much smaller than that of 2MM. Under this conical laser beam, the greater the thickness of the workpiece is, the lower the accuracy will be, so the larger the slit is.

Light spot size

When the conical laser beam is gathered together, the spot becomes smaller and smaller. Therefore, the accuracy of the laser cutting is also getting higher and higher, especially the width of the slit becomes smaller and smaller. According to our laser professional and technical personnel, at this time, the smallest spot can reach 0.01mm. This is also one of the factors that affect the cutting accuracy of laser cutting machine.

Workbench

Whether it is a simple workbench or a high precision worktable, it will affect the effect of laser cutting.

Workpiece material

The cutting accuracy of laser cutting machine is slightly different for different materials. Even if the same material is used, the accuracy of cutting will vary if the composition of the material is different. Therefore, the material of workpiece has certain effect on the accuracy of laser cutting.

How to evaluate the quality of fiber laser engraving machine?

How to evaluate the quality of fiber laser engraving machine?

Laser processing as the 21st century advanced manufacturing technology, has broad prospects for development. In the general material of the laser engraving process, due to faster cutting speed, parts of the thermal deformation is very small, cutting parts of the dimensional accuracy depends mainly on the laser engraving machine table mechanical precision and control accuracy. In the fiber laser engraving process, the use of high-precision cutting device and control technology, dimensional accuracy can be umlevel.

For laser engraving processing, the evaluation of its processing quality mainly includes the following principles:
1. Cutting smooth, no stripes, no brittle fracture;
2. Slit width is narrow, which is mainly related to the size of the laser beam spot diameter;
3. The slit vertical degree is good, heat affected area is small;
4. No material burning, no melting layer formation, no large slag;
5. The incision surface rough plating, the size of the surface roughness is the key to measuring the quality of laser cutting surface.

In addition to the above principles, the processing of the molten layer during the state and the final shape, a direct impact on the processing quality evaluation indicators.

In short,if you are interested in digital printing, our official website provides a variety of heat transfer equipment, such as hot sublimation printers, hot sublimation paper and ink, and so on, and ensure quality.

How to maintain the laser cutter in high temperature environment?

How to maintain the laser cutter in high temperature environment?

When the temperature is rising, the customers must be in the bud, and the maintenance of the laser cutter is very important. This can effectively avoid the damage of the laser generator, improve the working efficiency and prolong the service life of the machine.

 


Avoid condensation

The cooling water temperature should not be too different from the air temperature. Laser and optical lenses are both used for water cooling. As the water in the air is cooled, it condenses into water. When the temperature of the cooling water is below 5-7 degrees, the surface of the laser and optical lens will have condensation, which greatly affects the efficiency of the laser and the transmittance of the optical lens. The service life of energy and optical accessories is very great.

The laser and the cutting head are part of separate water cooling suggestion that the user set the laser at low temperature to set the water temperature to be about 26 degrees. The water temperature of the cutting head and the optical fiber is about 30 degrees (depending on the temperature and humidity value), and the order of the switching machine is strictly observed in summer.

(Notice:Can not appear laser shutdown, water cooler is still running.)

Be careful:

1. When the laser equipment is switched off, the water cooler should also be closed to prevent condensation resulting from excessive temperature difference.

2, it is strongly required that the integrated operating room customers install air conditioning or laser installed in the air-conditioned room, and keep the air conditioning continuously and steadily (including the evening) to keep the indoor temperature and humidity, or to open the air conditioner for half an hour, and then open the laser equipment and the water cooler.

Maintain cooling system and cooling water

When the temperature rises in summer, the working pressure of the cooling system of the laser cutting machine increases. It is suggested to check the internal pressure of the internal press before the high temperature. The pressure of the equipment of different manufacturers is not the same. It is suggested that the specific parameters of the equipment manufacturers should be consulted before the maintenance.

As the temperature is high in summer, the deterioration speed of cooling water will also be accelerated. It is suggested that the users use regular distilled water or pure water to clean water scale and replace water and filter core (not more than 15 days in summer). The scale method should be operated under the guidance of the equipment manufacturer.

Maintain guide rail

 

Guide rail should be often clean, remove dust and other debris, to ensure that the equipment transmission part of lubrication, no debris. Regular cleaning and lubrication, to ensure that the machine in the process of accurate positioning to achieve more accurate cutting, improve product quality.

Maintain control cabinet

Because the dust of the laser cutting machine is mainly metal powder, it is suggested to regularly cut off the power to clean the dust in the laser cutting machine cabinet and check the working condition of the radiator fan.

About “how to maintain laser cutting machine under high temperature?” A few points have been listed in the solution. According to the steps, the life of laser cutting machine is relatively longer.
