Choose an ideal cooling solution for your CNC router spindle

The cooling device installed on the spindle may seem to be a very small part of the whole CNC router, but it can affect running of the whole CNC router. There are two kinds of cooling for the spindle. One is water cooling and the other is air cooling. Many CNC router users are quite confused when it comes to which one is better. Well, today we are going to briefly analyze their differences.

1. Cooling performance

Water cooling, as its name suggests, uses circulating water to take away the heat generated by the high speed rotating spindle. This is in fact a very effective way to take away the heat, for the spindle will remain below 40 degree C after water runs through it. However, air cooling just uses cooling fan to dissipate the spindle’s heat and it is easily affected by the ambient temperature. Besides, water cooling, which comes in the form of industrial water chiller, enables temperature control while air cooling doesn’t. Therefore, water cooling is often used in high power spindle while air cooling is often the consideration of low power spindle.

2. Noise level

As mentioned before, air cooling requires cooling fan to dissipate the heat and cooling fan makes great noise when it is working. However, water cooling mainly uses water circulation to dissipate the heat, so it is quite quiet during the operation.

3. Frozen water problem

This is very common in water cooling solution, i.e. industrial water chiller in cold-weather condition. In this circumstance, water is easy to get frozen. And if users don’t notice this problem and run the spindle directly, the spindle may be broken in just a few minutes. But this could be dealt with by adding diluted anti-freezer into the chiller or adding a heater inside. For air cooling, this is not a problem at all.

4. Price

Comparing with water cooling, air cooling is more expensive.

To sum up, choosing an ideal cooling solution for your CNC router spindle should be based on your own needs.

7 industries in which laser welding machine plays a key role

Laser welding has become a part of our daily life and you can often see the trace of laser welding in the items that are commonly seen. In fact, laser welding machine has completely replaced traditional welding techniques in 7 industries. And today, we are going to list them one by one.

Piping industry: water pipe connector, reducing joint, shower fittings and large pipe welding all applied laser welding technique.

Glasses industry: the buckle, the stainless steel/titanium alloy glasses frame require high precision laser welding.

Hardware industry: impeller, water kettle handle, complicated stamping parts and casting parts use laser welding machine.

Automobile industry: motor cylinder head gasket and hydraulic tappet rod seal welding, sparking plug welding and filter welding all require laser welding technique.

Medical industry: medical device and its sealing elements and structural parts welding use laser welding machine to perform welding.

Electronics industry: seal welding of solid-state relay, welding between connector and connector, welding of structural parts of smart phone and MP3 all require laser welding technique.

Home appliance hardware industry: kitchen and bathroom stainless steel door handle, clock, sensor, high precision machinery can often see the trace of laser welding.

Laser welding machine features high focused energy, no pollution and small welding point. It can weld a wide variety of materials with high flexibility and high efficiency. Some laser laser welding machines even integrate with robotic arm, which can achieve a high level of automation.

Laser welding machine uses high power fiber laser or YAG laser source to realize high energy welding. As the heat sources, these two types of laser sources tend to generate lots of extra heat. If those heat continues to accumulate, their lifetime will be greatly affected. And at this time, an industrial water chiller would be ideal. S&A CWFL series and CW series air cooled chillers are suitable to cool fiber laser welding machines and YAG laser welding machines respectively. They feature high precision temperature control and offer various temperature stability to choose from. Some bigger industrial water chiller models even support Modbus-485 communication protocol, making remote control of the chiller become a reality.

What kinds of change can laser bring to glass processing?

Laser processing as a new manufacturing technique has immersed in different industries in the recent years. From the original marking, engraving to big metal cutting and welding and to later micro-cutting of high precision materials, its processing ability is quite versatile. As its applications continue to have more and more breakthrough, its ability to process many different kinds of materials has improved a lot. To put it simply, the potential of laser application is quite huge.

Traditional cutting on glass materials

And today, we are going to talk about laser application on glass materials. We believe that everyone comes across various glass products, including glass door, glass window, glassware, etc.. With glassware being so widely used, the processing demand of glass is huge. The common laser processing on glass is cutting and drilling. And since glass is quite brittle, special attention needs to be paid during the processing.

Traditional glass cutting requires manual cutting. The cutting knife often uses diamond as the knife edge. Users use that knife to scribe a line with the assistance of a rule and then use both hands to tear it apart. However, the cut edge would be quite rough and needs to be polished. This manual method is only suitable for cutting glass of 1-6mm thickness. If thicker glass is needed to be cut, kerosene needs to be added on the surface of the glass before cutting.

This seemingly outdated way is in fact the most common way of glass cutting in many places, especially glass processing service provider. However, when it comes to plain glass curve cutting and drilling in the middle, it quite hard to do that with that manual cutting. Plus, the cutting precision can not be guaranteed.

Waterjet cutting also has quite a lot of applications in glass. It uses water coming from high pressure water jet to achieve high precision cutting. Besides, waterjet is automatic and is able to drill a hole in the middle of the glass and achieve curve cutting. However, waterjet still needs simple polishing.

Laser cutting on glass materials

In the recent years, laser processing technique has experienced rapid development. The breakthrough in ultrafast laser technique enables high precision laser technique continues to develop and gradually immerses into glass processing sector. In principle, glass can better absorb infrared laser than metal. Besides, glass can not conduct heat very efficiently, so the laser power needed to cut the glass is much lower than that to cut the metal. The ultrafast laser used in cutting glass has changed from original nanosecond UV laser to picosecond UV laser and even femtosecond UV laser. The price of the ultrafast laser device has dropped dramatically, indicating bigger market potential.

Besides, the application is heading towards high-end trend, such as smart phone camera slide, touch screen, etc.. Leading smart phone manufacturers basically use laser cutting to cut those glass components. With the demand of smart phone increases, the demand of laser cutting would definitely increase.

Previously, laser cutting on glass can only maintain at 3mm thickness. However, the last two years witnessed a huge breakthrough. Right now, some manufacturers can achieve 6mm thickness laser glass cutting and some even reach 10mm! The laser cut glass has the advantages of no pollution, smooth cut edge, high efficiency, high precision, a level of automation and no post-polishing. In the coming future, laser cutting technique might even be used in automobile glass, navigator glass, construction glass, etc..

Laser cutting can not only cut glass but also weld glass. As we all know, combining glass is quite challenging. In the past two years, institutes in Germany and China successfully developed glass laser welding technique, which makes laser have more applications in the glass industry.

Laser chiller that is specifically used for glass cutting

Using ultrafast laser to cut glass materials, especially those used in electronics, requires the laser equipment to be highly precise and reliable. And that means an equally precise and reliable laser water chiller is a MUST.

S&A CWUP series laser water chillers are suitable for cooling ultrafast lasers, such as femtosecond laser, picosecond laser and UV laser. These recirculating water chillers can reach up to ±0.1℃ precision, which is leading in the domestic laser refrigeration industry.

Laser cutting application in laptop processing

As technology continues to develop, traditional industrial manufacturing businesses are facing the challenge of deep transformation. One direction is to turn to high precision processing with higher additive value and stronger technical barrier while improving efficiency. Laser cutting machine is quite popular among high precision 3C device and accounts for a big share in the micro-cutting applications in laptop.

Laser cutting machine features high efficiency and cutting quality with smooth cut edge. Users just have to design the shape on the computer and within a few minutes, the shape comes out. Based on the development trend of laptop in the recent years, the inner components of the laptop becomes smaller, more precise with higher level of integration, which posts a higher requirement to the welding and cutting techniques applied.

Because of superior physical quality, laser can process various kinds of metals and non-metals, especially high hardness, high brittleness and high melting points, making it very ideal in high-end material precision processing. It is immersed into the whole production process in 3D product, including cutting and welding of product’s internals, surface high precision processing of electronics and polymer, drilling and marking, cover laser cutting, Home key laser cutting, FPC laser cutting, etc.. All these involve laser technique in the procedure.

As we all know, the cover is the direct way to protect the laptop, but it also affects the heat dissipation, weight and appearance. The major laptop cover materials include ABS engineering plastics, aluminum alloy, carbon fiber, titanium alloy or polycarbonate.

And there is a laser cutting machine that is quite suitable in laptop and other 3C products - UV laser cutting machine. UV laser cutting machine doesn’t contact the materials during cutting and the UV laser source is a kind of light source, for it features a very tiny heat-affecting zone. Therefore, it won’t cause carbonization or any kind of damage on the material surface while maintaining very precise cutting performance. And what helps the machine maintain its superior cutting performance is an effective air cooled chiller. S&A CWUL-05 air cooled chiller is ideally suited to cool 3W-5W UV laser marking machine and characterized by high accuracy of ±0.2℃, capable of providing ultra-precise temperature control. Plus, this chiller has proper pipeline inside, reducing the bubble generation which could cause great impact to the UV laser source.
