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.


S&A has 19 years of experience in industrial refrigeration and its CW series industrial water chillers are widely used in cooling CNC router spindles of different powers. These spindle chiller units are easy to use and install and offer cooling capacity from 600W to 30KW with multiple power specifications to choose from.

Anything to avoid clogging inside CNC water cooler?

Clogging is easy to occur in CNC water cooler if the water quality can not be guaranteed. To avoid this issue, the selection of water must be careful. Generally speaking, the suitable water for spindle chiller unit would be purified water, distilled water or deionised water. Besides, it is equally important to change out the water on a regular basis to keep the water clean. The changing frequency can depend on the actual situation, but normally we would suggest users to change out the water every 3 months.


After 19-year development, we establish rigorous product quality system and provide well-established after-sales service.

What is E3 error of CNC spindle cooler CW-5200 supposed to mean?

 E3 error code means that CNC spindle cooler CW-5200 has ultralow water temperature. This happens very often in winter in cold areas, for the ambient temperature in those areas is likely to be below 0 degree Celsius and water can easily freeze. To remove the E3 error, one can put a heating bar or add anti-freezer into the spindle chiller unit. For detailed instructions, please e-mail to techsupport@teyu.com.cn

Spindle Chiller Unit CW5000T, a Cooling Device That Can Maintain Temperature Stability of the CNC Marble Engraving Machine Spindle

 Last week, Mr. Bukoski, a marble engraving service provider from Poland, left a message in our website. He said that overheating problem occurred to his CNC marble engraving machine spindle very often and he was so desperate to find a cooling device that can control the temperature of the spindle.


After checking the parameters of the spindle of his CNC marble engraving machine, we recommended spindle chiller unit CW-5000T. Spindle chiller unit CW-5000T offers 0.86-1.02KW cooling capacity and temperature control accuracy of ±0.3℃. This precision can guarantee the temperature stability of the CNC marble engraving machine spindle. Besides, this chiller doesn’t consume much space and you can just put it everywhere you want. Therefore, many CNC machine users like to equip their CNC machines with spindle chiller units CW-5000T. What may surprise Mr. Bukoski even more towards this chiller is that it is dual frequency compatible in both 220V 50HZ and 220V 60HZ, which is very convenient.

Does antifreezer of spindle chiller unit need to be drained out in summer?

To prevent the situation that the spindle chiller unit stops working because of frozen water in winter, many users would add the anti-freezer. When summer comes, does the anti-freezer of spindle chiller unit need to be drained out? Well, that’s for sure. Anti-freezer is corrosive and it could become more corrosive after being used for a long time. Therefore, when summer comes, users should drain out the anti-freezer in time and fill with purified water or clean distilled water.


After 18-year development, we establish rigorous product quality system and provide well-established after-sales service.

The spindle chiller unit has no water circulation. Why?

If the spindle chiller unit has no water circulation, it is likely that the water channel inside is blocked. If it is the internal channel is blocked, users can flush it with clean water first and then use air gun to clear it. To avoid this situation, it is suggested to change out the circulating water on a regular basis and use clean distilled water or purified water as the circulating water.

After 18-year development, we establish rigorous product quality system and provide well-established after-sales service.

What is Special About Spindle Chiller Unit CW 3000 that a Vietnamese CNC Machine User Keeps Using it?

Mr. Tran from Vietnam owns a dozen of CNC metal cutting machines in his workplace and he provides metal cutting service for the local schools. He has been using S&A spindle chiller units CW-3000 to cool CNC metal cutting machine spindles for many years. Although some local chiller suppliers contact him for cooperation from time to time, he refused them and keeps using our spindle chiller unit CW-3000. So what is special about this chiller?

Well, S&A spindle chiller unit CW-3000 features 50W/°C radiating capacity, which means when water temperature rises by 1°C, there will be 50W heat taken away from the CNC metal cutting machine spindle. This makes spindle chiller unit CW-3000 perfect for CNC machine with small heat load. Besides, it has compact design and features ease of use, low maintenance rate and long lifetime. For Mr. Tran, ease of use is the key, for he is always so busy with his business and and doesn’t have plenty time to spend on the chiller. And spindle chiller unit CW-3000 really solves this issue. 

But please note that spindle chiller unit CW-3000 is passive cooling water chiller, so it doesn’t have refrigeration function.
