CO2 laser marking machine

1. Identify processing demands

Firstly, the buyers can determine their processing demands, the materials, and the dimensions, etc. And don’t expect that buying one marking machine can do everything. The manufacturers divide the marking machines into various models in order to deal with various processing tasks. If the machine model cannot match the processing demands, it will cause huge waste and will not achieve good effect.

Therefore, before purchasing the marking machine, the buyers must fully explain the processing contents and requirements to the suppliers. The contents include the size of work-pieces, the quality, thickness and weight of materials, and the marking effect, etc.

2. Understand the performance of important parts of the marking machine

1) The quality of the laser is the most important factor affecting the quality of the marking machine. It is recommended to choose a marking machine with a well-known and well-configured laser as much as possible to ensure your marking effect.

2) The optical lens of the marking machine directly determines the quality of the marking effect. The good optical lens can effectively increase the marking speed of the laser machine and ensure the accuracy of the graphics.

3) Check the quality and performance of screws and guide rails, which are also an important part of the marking machine. Good screw and guide rails guarantee the accuracy and performance of the marking machine during long-term use.

3. Good after-sales service

No matter how well a marking machine is made, the users will encounter various problems during the operating process. When the users encounter the unsolvable problems, whether the company can provide timely solutions is particularly important. This is also an important factor that the users need to consider while purchasing a marking machine.

The cost of machine and maintaining combines the integrated CO2 laser marker price. A responsible CO2 laser marking machine manufacturer provide low cost laser marking machine with considerations of the two aspects. The low cost machine may have not low CO2 laser marker price, but it has high-quality and low-cost expend, and it is also easily to maintain, and long time to use. All of these factors compose the low cost laser marking machine.

In order to guarantee the working efficiency and extend the service life of the machine, the users must maintain the CO2 laser marking machine regularly.

1. Cleaning of optical lens

The lens of the laser marking machine is easy to be stained with dust or other contaminants. It needs to clean the lens every day.

For the cleaning of lens, the operators shall wipe the lens gently, and not damage the surface coating. The process of wiping the lens should be done gently to prevent falling. When installing the focusing lens, the operators need to make sure to keep the concave surface down.

2. Cleaning of the guide rail

During the operation of the machine, a large amount of dust and smog may be generated. And the smog and dust may accumulate on the surface of the guide rail for a long time. It will have a great impact on the accuracy of the machine. It can form corrosion spots on the surface of guide rails, which shortens the service life of the machine. Therefore, it needs to clean the guide rail of the machine every half a month. And turn off the machine before cleaning.

1. Fastening of screws and couplings of CO2 laser marking machine

After the motion system has been working for a period of time, the screws and couplings will become loose. It will affect the stability of the mechanical motion. Therefore, during the operation process, the operators observe whether there are abnormal noises or phenomena in the transmission parts. And then, if finding any problem, it needs to fasten or maintain in time. In addition, the operators shall use tools to tighten the screws one by one regularly. The users shall tighten the screws and couplings for the first time after operating the machine for about one month.

4. Checking the optical path system

The optical path system mainly consists of the reflecting lens and the focusing lens. There is no deviation problem of the focusing mirror in the optical path. But three reflecting lenses are fixed by the mechanical parts. Generally, there is no deviation under normal conditions. But it is better for the user to check the optical path before the operation each time.

The operation of the CO2 laser marking machine is relatively simple, without complicated procedures. The following briefly introduces the operation steps of the laser marking machine for reference.

1. Steps of starting up
