Anything to do if plastic laser cutter water chiller system can’t refrigerate properly?

 If water chiller system which cools plastic laser cutter can’t refrigerate properly, it could be due to:

1.The dust gauze is covered with dust so the the ventilation of the laser chiller system is poor. It is suggested to take out and wash the dust gauze regularly;
2.There is foreign substances in the circulating water, which causes the blogging inside the water loop. In this case, use purified water or clean distilled water as circulating water and change it every 3 months;
3.The supplied power is too low. It is suggested to add a voltage stabilizer;

4.The temperature controller of the water chiller system is broken and is unable to indicate water temperature. In this case, turn to the chiller supplier for a new one.

What is the difference between laser cutting and 3D printing?

To tell the difference between laser cutting and 3D printing, the first thing is to find out their respective definition.

Laser cutting technique is a “deducting” technique, which means it uses laser source to cut the original material based on the designed pattern or shape. Laser cutting machine can perform speedy and accurate cutting on different metal and non-metal materials like fabric, wood and composite materials. Although laser cutting machine can help speed up the prototype making process, but it is limited to building parts that require welding or other laser technique to make the prototype.

On the contrary, 3D printing is a kind of “adding” technique. To use a 3D printer, you need to create a 3D model that you are going to “print” on your computer first. Then the 3D printer will “add” the materials like glue and resin layer by layer to actually build the project. In this process, nothing is deducted. 

Both laser cutting machine and 3D printer feature high speed, but laser cutting machine is slightly advantageous, for it can be used in prototype making. 

In many situations, 3D printer is often used in simulation design to identify the potential flaw in the subject or is used to produce mold of certain kinds of product. This is mainly due to the fact that 3D printer can use not so durable materials. 

In fact, cost is the main reason why many manufacturers turn to laser cutting machine instead of 3D printer. The resin used in 3D printer is quite expensive. If 3D printer employs cheaper adhesive-bonded powder, the printed subject is less durable. If the cost of 3D printer reduces, it is believed that 3D printer will be more popular. 

To get the most out of laser cutting machine, manufacturers usually would add an industrial cooling system to take away the heat from the heat-generating component. S&A Teyu industrial cooling system is designed with laser system as its target application. It is suitable for cooling CO2 laser, UV laser, fiber laser, YAG laser and so on with cooling capacity ranging from 0.6KW to 30KW.

Fiber laser cutting machine increases market share in the elevator market

Elevator is the equipment that transports people or cargo from between different floors and it is a MUST-HAVE equipment in tall buildings. As we all know, the common materials of elevator are stainless steel plate and materials with film. These materials require high standard brightness and cleanness. As the market demand increases, the new elevator development cycle becomes shorter. Besides, there are so many different kinds of sheet metal parts of elevator and some of them requirement customization. Traditional multi-station punching machines are difficult to meet the processing needs and it also takes a long time to build a mold, which prolongs the production time. In this circumstance, fiber laser cutting machine was invented and is gradually increasing its market share in the elevator market. So what is the difference between traditional processing technique and fiber laser cutting technique?

1.Traditional processing technique
It often refers to multi-station punching machine. This machine includes procedures like milling, shaving, drilling, grinding and these procedures require external force and harder tools to realize the cutting job. It’ s quite complicated and the parts can easily deform, wasting cost and labor. 

2.CO2 laser processing
CO2 laser cutting machine was the first laser processing equipment used in domestic elevator industry. It uses non-mechanical energy like light and electricity to do the cutting job and can also realize hard material processing. Comparing with traditional processing, CO2 laser cutting machine is non-contact, ease of processing, safe and more environmental friendly.

3.Fiber laser processing
Elevator manufacturing mainly relies on about 3mm thick stainless steel. Using CO2 laser cutting machine will consume more electricity and more CO2 gas. What’s more, with disadvantages like high cost and complicated commissioning, CO2 laser cutting machine has fallen behind. On the contrary, fiber laser cutting machine has much faster speed with lower running cost and is able to cut highly reflective materials like copper and aluminum. Therefore, it is also gradually replacing CO2 laser cutting machine and becomes the first option in elevator manufacturing. 

There are two parts of fiber laser cutting machine generate heat during operation - fiber laser source and laser head. To maintain these two components at a normal temperature range, many fiber laser cutting machine users would consider buying two separate chillers to do that. But in fact, there is a more cost-effective solution. S&A Teyu CWFL series air cooled recirculating water chiller features dual cooling circuit configurations, providing effective cooling for the fiber laser source and the laser head respectively and at the same time reducing the potential of condensation.

The advantage of carbon steel fiber laser cutter

We can now see the trace of laser cutting in almost every aspect of our life. It has already had wide application in sheet metal processing, sign making, kitchenware making and so on. Different kinds of metal fiber laser cutting machines and steel plate fiber laser cutting machines have attracted so many fans in metal industry. Fiber laser cutting machine is suitable for cutting carbon steel with bigger size and thickness. With high efficiency, superior stability, high precision and speed, it has become the first option in carbon steel processing.

Fiber laser cutting machine uses fiber laser as the light source. As we know, fiber laser is a novel laser source that can output high energy & density laser light, making it applicable to perform cutting and engraving on high density metals like carbon steel, stainless steel, aluminum alloy and so on. So what is the advantage of carbon steel fiber laser cutter? 

For carbon steel processing, the most important thing is to guarantee the accuracy of the product. Especially some hardware parts, for they are mostly used in automobile, ship building, home appliance, high precision parts and so on. And fiber laser cutter which is characterized by high precision makes it the ideal tool. In addition, fiber laser cutter can improve production efficiency and reduce labor cost. Nowadays, automation has become the mainstream in processing industry, so less labor cost and higher production efficiency are going to be the two important concerns for the enterprises. 

The advantage of carbon steel fiber laser cutter:

1.High quality cutting with small deformation and smooth cutting edge. No need of post-processing.
2.High cutting speed. Can realize continuous cutting with shortest cutting route;
3.Superior stability. Stable laser output with long life and easy maintenance;
4.Flexibility. Can work out any shape with ease of use.

As mentioned before, carbon steel fiber laser cutter uses fiber laser as the laser source. Fiber laser, just as other kinds of laser sources, also releases heat during operation. The higher the power of the fiber laser, the more heat it is going to generate. To take away the heat in time, one needs a closed loop air cooled chiller. Don’t worry. S&A Teyu CWFL series laser cooling system could help. It is specifically designed for cooling fiber laser ranging from 500W to 20KW.

What is UV laser cutting machine?

 Working principle of UV laser cutting machine

UV laser cutting machine refers to high precision laser cutting machine that uses 355nm UV laser. It emits high density & high energy laser light on the material surface and realize cutting by destroying the molecular bond inside the material. 

The structure of UV laser cutting machine

UV laser cutting machine consists of UV laser, high speed scanner system, telecentric lens, beam expander, vision positioning system, electronic control system, power source components, laser water chiller and many other components. 

Processing technique of UV laser cutting machine

With focal round light spot and scanner system moving back and forth, the material surface is stripped layer by layer and finally the cutting job is done. The scanner system can reach up to 4000mm/s and the scanning speed times decide the efficiency of the UV laser cutting machine. 

Pros and cons of UV laser cutting machine

Prons: 
1.High precision with smallest focal light spot below 10um. Small cutting edge;
2.Small heat-affecting zone with low carbonation to the materials;
3.Can work on any shapes and easy to operate;
4.Smooth cutting edge with no burr;
5.High automation with superior flexibility;
6.No need for special holding fixture.

Domestic high power fiber laser cutters will have a bright future

Nowadays, fiber laser cutters are no doubt the major player in the metalworking field and they are heading towards larger format, higher precision and higher power. This has made fiber laser cutter have a wider application. However, the high power fiber laser cutter still makes people hesitate to buy. Why? Well, the huge price is one of the reasons.

Fiber laser can be classified into 3 categories based on their powers. Low power fiber laser (<100W) is mainly used in laser marking, drilling, micro-machining and metal engraving. Middle power fiber laser(<1.5KW) is applicable in laser cutting, welding and surface treatment of the metal. High power fiber laser (>1.5KW) is used for thick metal plate cutting and 3D processing of special plate. 

Although our country began to develop high power fiber laser a little late, comparing to the foreign countries, but the development was quite encouraging. Raycus, Hans and many other laser machine manufacturers have developed 10KW+ fiber laser cutters in the past few years, which breaks the dominance of the foreign counterparts. 

It is expected that in the coming future, domestic high power fiber laser will account for bigger market share with lower price, shorter lead time, faster service speed. 

For high power fiber laser, one of the key components is the cooling system. Proper cooling can let high power fiber laser stay away from overheating in the long run. S&A Teyu CWFL series laser cooling chiller is ideal for cooling high power fiber lasers from 1.5KW to 20KW. Find out more at https://www.teyuchiller.com/fiber-laser-chillers_c2
