Types of CNC spindle motors on ATO.com

ATC Spindle Motor (Automatic Tool Changer Spindle motor)

The rear end of the electric spindle is a cylinder structure. The inside of the cylinder uses the air pressure to push the thimble to hit the middle tie rod to make the chuck extend outward so that the tool falls off. Then the equipment can use the shaft platform to automatically grab the tool, and then the rear end of the spindle uses a solenoid valve to release it. The air pressure is cut off, thereby clamping the tool, a process known as automatic tool change.

Automatic tool changer spindles are often used in areas such as splitter cutting, or in cutting areas such as billboard cutting. The clamping force of the clamping tool of the automatic tool changing spindle is great, which can cut stably and can automatically change the tool. It saves time and effort. The ATC spindle has good cutting quality, flat incisions, no burrs, no dust, and low noise. It can be used for circuit boards of various shapes and improve work efficiency.

Air-cooled spindle motor

ATO air-cooled spindle motor comes with a small fan to dissipate heat, without coolant, not easy to rust. It is suitable for cold areas.
If you want to buy an air-cooled spindle, you need to know some of its advantages. Details are as follows:

• High speed: It has the merits of high-speed, precision-matched bearings, and rigid or elastic preload structure. It can obtain a higher speed so that the tool can play the best cutting effect.
• High precision: High precision bearings are manufactured with high precision parts.
  High Efficiency: The speed can be changed in continuous fine-tuning, so the cutting speed can be controlled in real-time during the entire machining process, so as to obtain the maximum machining efficiency.
• Low noise: The spindle has the advantage of low noise in the case of high-speed rotation.
  Our website can provide you with air-cooled spindle motors of various powers for your purchase.

Water-cooled spindle motor

The water-cooled spindle motor has a good cooling effect, low noise and low price. It is very suitable for hot areas, and it is designed for metal and stone processing. If you plan to buy a water-cooled spindle, you need to know several advantages of the water-cooled spindle:

• Accuracy: The axial and radial run out of the mine spindle is basically below 0.003 mm, which makes the water-cooled spindle more accurate.
• Effect: The water-cooled spindle uses water circulation to cool the heat generated by the high-speed rotation of the spindle, which is better than the air-cooled spindle that uses a fan to dissipate heat.
• Noise: The water-cooled spindle is basically silent, but the air-cooled spindle inevitably produces some noise.

How to choose a spindle motor for CNC router?

The spindle motor of the engraving machine is one of the core parts of the CNC engraving machine. The performance of the spindle directly determines the engraving effect, engraving quality, engraving accuracy and speed of the engraving machine.

The ATO spindle motor has 3 types: air-cooled spindle, water-cooled spindle and ATC spindle. If the temperature in your area is relatively cold, you can achieve a better cooling effect by choosing an air-cooled spindle. If the temperature in your area is hot, then you are better off choosing a water-cooled spindle. If you need a better cooling effect, you can also add a chiller to keep the water temperature at a relatively low state, which can better achieve the effect of cooling the spindle. If your area is hot and you need a woodworking engraving machine, don't worry about choosing a water-cooled spindle to get your boards wet, because the water-cooled spindle is internally circulated for cooling and the water won't come out. With the development of science and technology, automatic tool-changing spindles have also appeared in recent years. ATC spindle is very popular in the market, especially in the field of automation, ATC spindle has become a hot word in the industry.

According to the specifications of the equipment, the spindle configuration of the engraving machine is also different. If you want to pursue high processing efficiency, you need a spindle motor with a power of more than 2.2kW.
