Laser micro-machining requires high precision water chiller

 Rapid development of laser manufacturing

Laser technique as a material processing tool is quite popular in industry sector and has great potential. By 2020, the domestic laser product market scale has already reached nearly 100 billion RMB, accounting for more than 1/3 share of the global market.

From laser marking leather, plastic bottle and button to laser metal cutting & welding, laser technique has been used in industries that are related to people’s daily life, including metal processing, electronics manufacturing, home appliance, automobile, battery, aerospace, shipbuilding, plastic processing, art craft, etc. Even so, laser manufacturing has been facing a bottleneck problem - its segment markets only include metal processing, electronics manufacturing, battery, product packaging, advertising and so on. The current laser industry needs to think about how to explore more segment markets and realize scale application. 

High-end application requires high precision

Since 2014, fiber laser cutting technique has been applied in large scale and gradually replacing traditional metal cutting and some CNC cutting. Fiber laser marking and welding techniques also witnesses a rapid growth. Nowadays, fiber laser processing has taken up more than 60% of the industrial laser application. This trend also promotes the demand of fiber laser, cooling device, processing head, optics and other core components. Generally speaking, laser manufacturing can be divided into laser macro-machining and laser micro-machining. Laser macro-machining refers to high power laser application and belongs to rough machining, including general metal processing, aerospace parts manufacturing, car body processing, advertising sign making and so on. These kinds of application requires not so high precision. Laser micro-machining, on the other hand, requires high precision processing and is often used in laser drilling/ micro-welding silicon wafer, glass, ceramics, PCB, thin film, etc. 

Limited to the high cost of the laser source and its parts, the market of laser micro-machining hasn’t been fully developed. Since 2016, domestic ultra-fast laser processing has begun scale applications in products like smart phones and the laser is used for fingerprint module, camera slide, OLED glass, internal antenna processing. The domestic ultra-fast laser industry is developing fast. By 2019, there have been more than 20 enterprises in the development and production of picosecond laser and femtosecond laser. Although high-end ultra-fast laser is still dominated by European countries, domestic ultra-fast lasers have already become quite stable. In the coming years, laser micro-machining will become the most potential area and high precision processing will become the standard of some of the industries. That means ultra-fast lasers will have more demand in PCB processing, photovoltaic cell PERC grooving, screen cutting and so on. 

S&A Teyu launched ultra-fast laser chiller

Domestic picosecond laser and femtosecond laser are developing towards the trend of high power. In the past, the major differences between domestic ultra-fast laser and the foreign one are stability and reliability. Therefore, a precise cooling device is very crucial to the stability of the ultra-fast laser. Domestic laser cooling technique has been developing rapidly, from the original ±1°C, to ±0.5°C and later ±0.2°C, the stability is getting higher and higher and meets the need of most of the laser manufacturing. However, as the laser power is getting higher and higher, the temperature stability is hard to maintain. Therefore, developing ultra-high precision laser cooling system has become a challenge in the laser industry.

But luckily, there is one domestic company that had this breakthrough. In 2020, S&A Teyu launched CWUP-20 laser cooling unit which is specifically designed for cooling ultra-fast lasers like picosecond laser, femtosecond laser and nanosecond laser. This closed loop laser chiller features ±0.1℃ temperature stability and compact design and is applicable in many different applications. 

Since ultra-fast laser is commonly used in high precision processing, the higher the stability the better in terms of the cooling system. In fact, the laser cooling technique featuring ±0.1℃ stability is quite scarce in our country and used to be dominated by countries like Japan, European countries, United States and so on. But now, the successful development of CWUP-20 broke this dominance and can better serve the domestic ultra-fast laser market.

How to optimize the performance of the air cooled chiller unit which cools picosecond laser cutting machine?

To optimize the performance of the air cooled chiller unit which cools picosecond laser cutting machine is very necessary. On one hand, the performance of the air cooled chiller unit is decided by its own quality. On the other hand, regular maintenance and suitable working environment also play a role. It is suggested to put the laser cooling unit in a spot with below 40 degree Celsius and perform maintenance like changing out water or removing dust from time to time.

After 19-year development, we establish rigorous product quality system and provide well-established after-sales service. We offer more than 90 standard water chiller models and 120 water chiller models for customization.

Working principle and categories of laser metal cutting

 Metal laser cutting is one of the most important applications of laser processing. With the development of fiber lasertechnique, metal laser cutting machine will gradually replace traditional metal cutting device.

Metal laser cutting is quite different from traditional metal cutting in working principle. Metal laser cutting indicates posting laser light beam to the surface of the metal part. Then the metal part will melt or evaporate so that cutting and engraving purpose can be fulfilled. Laser cutting has many advantages, such as high speed, material saving, low operation cost and smooth cutting/engraving edges. 

Based on the working principle, metal laser cutting can be categorized into 3 types:

1.Cutting through evaporation

This indicates using high energy and high density laser beam to heat up the metal . The metal part that absorbs the laser beam will evaporate in a short time and become vapor, leaving a cut on the metal surface. Since heat of evaporation is generally big, this kind of laser cutting requires laser beam of high power and high density

2.Cutting through melting 
With this kind of laser cutting, the metal material will melt down after absorbing the heat from the laser. It only needs the 1/10 energy of the first cutting type. It is mainly used to cut dysoxidizable or reactive metals, such as stainless steel, titanium, aluminum and its alloy. 

3.Oxygen cutting
It uses laser as the preheating source and use reactive gas like oxygen as the cutting air. Using this kind of laser cutting, the cutting speed is much faster than the cutting through evaporation and melting. Oxygen cutting is commonly used to cut oxidizable metal materials such as carbon steel, titanium steel and heat treatment steel. 

As the major laser source of metal laser cutting machine, fiber laser plays an important role and needs special protection. And the ideal protection would be sufficient cooling by a laser cooling unit. S&A CWFL series laser cooling unit is specially suited for cooling fiber laser and is characterized by dual temperature control system.
