TOPIC 4: What are the different models of CO2 laser machine?

According to different laser powers,Jinan Sequoyatec Co., LTD.Provides CO2 laser machine with 40w 60w 80w 100w 130w and 150w, 180w, 250w, 300w. According to different working sizes, there are have : 600*400mm, 600*900mm, 1300*900mm, 1600*1000mm, 1300*2500mm. According to customer demand, other sizes can be customized.

TOPIC 5:How much does a CO2 laser machine cost? How to buy an affordable CO2 laser machine within your budget?

The CO2 laser machine cost is closely related with its configuration. Although the CO2 laser machine appearance sometimes you feel you see is almost the same, the realization of the function is the same of (cutting, engraving and so on), but according to the different configurations, its price, processing speed, machine service life will be different. Before you purchase, there are several items you have to confirm:

1. Learn about what material you wants to process by the CO2 laser machine. Non-metal material usually requires CO2 laser machine, but we also provide MIXED Cutting Machine that can cut thin stainless steel and carbon steel (within 3mm). 

2. Select the appropriate machine working size according to the size of the product to be processed. However, it should be noted that the large working size of the machine is not necessarily good.Because machines with large working sizes are expensive, while some machines with poor quality have unstable laser output at various points on large-format surfaces, resulting in different shades of engraving products on the same table, so choosing the right working size is very important.

3. Check the type of work you want to use the CO2 laser machine for. If you process column material, such as glass cup, bottles, bamboo, egg, you have to requires the machine fits rotary device( rotary attachment) and moving table. The rotary devices are different for holding bottles and egg, so do remember list what type of work you do. Laser machines are designed for different applications, such as fabrics CO2 laser cutting machine, marble CO2 laser engraving machine, sign CO2 laser engraving machine, even label CO2 laser cutting, etc. Fabrics CO2 laser cutting machine requires special working table and support to hold Fabrics rollers, marble processing requires rolling table for lifting and moving easily, label cutting requires a scanner which could scan the edge of label to guide the laser head to cut. If this is something you want to invest in, buy a machine that can do that.

4. Check laser tube power you want. Wood cutting and paper cutting requires different laser tube power, cutting thickness also requires different power, so this is the important element you should consider too. If your work is mainly engraving, the 40w 60w or 80w laser power is a good choice.If your work is engraving and cutting, here is a form about cutting different thicknesses of materials with different laser power:

5. After-sales service of machinery is also very important, but people often fall into a wrong myth. They do not know that machinery of good quality are not easy to damage, so there is no need for frequent maintenance, but it is a machine with poor quality. Frequent damage requires special attention to this point. After-sales service has a direct impact on the production efficiency. If a machine that has been purchased fails to solve the problem, it will directly cause production to stop and cannot work. Therefore, after-sales service is very important. Therefore, when customers choose laser engraving machine products, they must actively understand the market, analyze the market, analyze which manufacturers produce better machines, the credibility is guaranteed, and which manufacturers have relatively good machine quality and better engraving effects. The information must take time to know.

6. Cooling system of the laser tube: the steady operation of the laser machine is largely dependent on the cooling system of the glass laser tube. Any problems with the cooling system may cause the laser tube failure. Therefore the laser machine has to be equipped with a water-cooling unit or chiller to cool the laser tube. The chiller keeps the water temperature at the given level. Freon gas which does not destroy the ozone layer is used as the refrigerant. The chiller provides the steady operation of the laser tube. If you buy a laser machine with the cooling system which consists of a plastic tank and an aquarium compressor, we think that the supplier has disrespected you. The chiller must properly fit the laser machine and conform to power of the installed laser tube. Sometimes Some suppliers deliberately install the chiller which does not meet the requirements for cooling the laser tube. The cooling circuit of laser machine must be equipped with the water flow sensor as the additional protection of the water cooled laser tube. In case if the sensor detects the lack of flow or poor water circulation, the laser machine will power off the laser tube automatically thus protect it from damages and save your money and time. The lack of protection for the laser optical path against dirt and dust contamination in the laser tube. There is no built-in laser tube protection against dirt and dust contamination at the outlet of laser tube in the some laser machines that causes fast failure of laser tube and decreases laser power during operation.

7. WHY CHOOSE SEQUOYATEC CNC?

1). High quality Starting with purchase the original part of the machine, then production and installation of machinery.
