DXTECH, as the advanced CNC laser machines manufacturer, mainly manufactures and supplies the laser cutting machines, laser welding machines, laser engraving machines and laser marking machines. Their functions and applicable materials are briefly introduced at below.

Laser cutting machine

The laser cutting machine of DXTECH is to use the high-density energy released when the laser beam irradiates the surface of the work-piece to melt and evaporate the work-piece to achieve the purpose of cutting. It has high precision, fast cutting speed and smooth cutting edges, not limited to cutting patterns.

According to different laser sources, DXTECH’s laser cutting machines are mainly divided into CO2 laser cutting machine and fiber laser cutting machine.

CO2 laser cutting machine is used for cutting non-metal materials, for example, acrylic materials, wood, leather, cloth, plastic and paper.

Fiber laser cutting machine is mostly used to cut metal materials, such as, carbon steel, stainless steel, alloy steel and galvanized sheets, etc.

Laser welding machine

The laser welding machine of DXTECH is also one of the important laser machines. The working principle of this machine is to use the pulse laser for welding. After beam expanding, reflection and focusing, the laser beam radiates on the surface of the work-piece. The surface heat diffuses to the internal through heat transfer. And the work-piece begins melting to form a specific molten pool. In this way, the laser welding machine completes the precision welding. The laser beam welding has the unique advantages of smooth welding seam, small focus spot, and high positioning accuracy.

The laser welding machine is suitable for welding the same metal materials, such as stainless steel, gold, silver, and alloy. And it is also applicable for welding many kinds of dissimilar metal materials. For example, the laser welder can weld copper and nickel, nickel and titanium, low-carbon steel and copper.

It is applicable to the electronic components, precision machinery, communications, and other industries. There are also many users in the phone batteries, sensors, medical devices, craft gifts, and clocks processing industries.

Laser engraving machine

The laser engraving machine of DXTECH is the equipment that uses the thermal energy of laser to engrave the suitable materials. And this machine uses laser beams to engrave permanent marks on the surface of various materials. The materials melt and vaporize physically under the laser engraving irradiation, resulting in engraving marks. As it is non-contact processing, the laser engraving machine will not cause mechanical deformation or damage on the work-piece.

The laser engraving machines can be divided into CO2 laser engraving machines and fiber laser engraving machines.

-CO2 laser engraving machine

Generally used for the engraving processing of non-metal materials, such as wood, acrylics, fabrics, plastics, paper and leather, etc.;

-Fiber laser engraving machine

Mainly for engraving most of metal materials, such as stainless steel, carbon steel, silicon steel, alloy steel and galvanized plates, etc;

Laser marking machine

The laser marking machine of DXTECH uses a laser beam to make permanent marks on the surface of various materials. Laser marking is the process of using laser energy to evaporate the surface material to expose the deep material, thereby marking exquisite patterns, trademarks and letters on work-piece.

Laser marking machine is mainly divided into CO2 laser marking machine, fiber laser marking machine, and UV laser marking machine.

– CO2 laser marking machine is the marking equipment using carbon dioxide laser technology for marking non-metallic materials mostly. For example, the materials for CO2 laser marking include wood, paper, epoxy resin, acrylic, leather, glass, ceramics, and rubber, etc.

– The fiber laser marking machine uses fiber as the working medium. And it can be mainly used to mark stainless steel, aluminum, carbon steel, and many other metal materials, as well as some non-metallic materials.

– And the UV laser marking machine uses the ultraviolet laser of the clod light source. It is mainly used in the high-end market of ultra-fine processing. The machine can mark on the surface of packaging bottles of pharmaceuticals, cosmetics, and other polymer materials, with very precise effect.

The cutting or engraving processing of a laser machine is to replace the traditional mechanical tool with invisible beam. It has the characteristics of high precision, fast cutting, not limited to cutting pattern limitation, and automatic operation. The laser machine saves materials, and the materials after laser processing have smooth incision, low processing cost. But we often encounter some faults when using the laser machine. In this article we will talk about the common problems and solutions in the process of using the laser machine.

1. Deformation of round holes or straight lines processed by laser

During the laser processing, the circular hole to be processed may be deformed and twisted. And some users may encounter that the straight line becomes a wavy line.

When this kind of problem occurs, we should first check whether the laser cutting control software is operating normally. For example, the users can draw a straight line to observe whether the laser head is moving in a straight line during processing. This can basically confirm the possibility of software problems. At the same time, this step can also find abnormal problems of the loosening of the mechanical structure.

After eliminating the possibilities of software and mechanical faults, we should think about whether the laser energy is too high. And the non-processing area is affected by the over high energy. We can observe whether the cutting edge of the work-piece is melting. The normal processing edge should be smooth and flat. In case of any melting, we should appropriately lower down the laser power or frequency parameters to solve the problem. There is also a relatively uncommon possibility. The deformation of the focusing lens in the laser head can also cause such problems. It can be judged by observing whether the beam from the laser head is concentric or not. If not, it needs to change the focusing lens.

2. Incomplete penetration in the process of laser processing

Such problem is very common in laser cutting machines, and the causes of problems are also varied. The laser cutting is a processing method in which the material is blown off while melting. So we can analyze whether it is not melted or not blown off.

First, analyze the situation of not melting. The reasons for not melting are generally insufficient power, and dirt on the focusing lens blocking the laser beam, etc. If the power is not enough, it can be increased by modifying the parameters on the laser cutting software. High-power laser controllers will have the problem of power attenuation during long-term use. Therefore, when purchasing the laser cutting machine, it is better to choose the one with enough power on the basis of meeting processing requirements.

If the problem is that there is something dirty on the lens, we can take out the lens to check. After confirming that the problem caused by the dirt, we can solve it by replacing or cleaning the lens. Please note that only use absorbent cotton or special lens cleaning paper dipped with absolute ethanol to clean the lens. It is strictly forbidden to touch the lens with hands or other objects to avoid damage to the lens coating.

3. The work-piece has burr when using laser cutting machine
   First of all, check if it is because of the problem of lens focusing. If the laser focus position is not correct, you can adjust the focus to solve this problem.

Secondly, check whether the laser is normal. On the premise of confirming the normal operation of the laser, further check whether the output power of the laser matches the power required. If not, it needs to be adjusted.

Cutting speed problem: the cutting speed is too slow and will also cause burr at the bottom of the cutting surface. At this time, it is necessary to speed up the cutting speed.

Gas problem: the purity of the auxiliary gas can also affect the quality of cutting. When the purity of the gas is not enough, the problem of causing burr will occur. It is necessary to replace the gas with higher purity for cutting.

4. Abnormal spark occurs during the laser processing
   If there is abnormal spark during the laser processing, it will affect the degree of quality at the cutting and engraving surface. At this moment, under the condition that other parameters are normal, the users can consider the following conditions. If it is because the loss of laser nozzle, the new nozzle should be replaced in time. In the case of no need for replacing new nozzle, the cutting gas pressure should be increased. It also needs to check whether the screw at the joint of nozzle and laser head becomes loose, and tighten the screw thread.
