Two-sided support system
Attaching the taper and flange surfaces of the tool holder to the mandrel can increase the contact rate to 114%, which is more suitable for high-speed conditions than ordinary tool holders. And it is beneficial to obtain the rigidity changes under more stable axial parallelism and strengthened dynamic speed.

Magnetic encoder
The high-frequency encoder and high-precision gear enable the controller to interpret the precise waveforms correctly, which can greatly improve the stability of the spindle at high speed, and make the low speed smoother, with a resolution of 0.001°.
Precision Bevel Ceramic Ball Bearings
It adopts European P4S ultra-precision bevel ball bearings, which are lighter, and have the characteristics of higher hardness, less unstable inertia, higher rigidity, and longer life than ordinary steel balls. The ceramic ball bearings can improve not only the limit speed and cutting rigidity, but can make the cutting range of the spindle more flexibly.
Annular Cooling Water Path
The cooling water passes through the spindle's annular water path to evenly cool the heat of bearing and the motor. In addition to keeping the spindle at the constant temperature, it can also reduce the run out of the tools and improve the to life and accuracy.
Air curtain protection
The compressed air is transmitted to the air curtain ring, filling the clearance of the rotating parts and releasing air, so that the internal bearing is protected by positive pressure to prevent the intrusion of cutting water and foreign matter.
Temperature sensor
The temperature monitoring of bearings is very important. The front and rear bearings plus the basic motor temperature sensor are not only directly related to the life of spindle bearings, the temperature data will directly reflect the tolerance of the cutting load, and the abnormal temperature can make the equipment stop to prevent from burning.

FAQ
Product FAQS
What is a built-in motor spindle? How is it different from a conventional spindle?
A built-in motor spindle integrates the motor directly into the spindle structure. The motor stator is installed inside the spindle sleeve, and the rotor connects directly to the spindle, eliminating the need for external mechanical transmissions such as belts or gears. This integrated design results in a more compact structure, higher rotational speeds, lower vibration, improved rigidity and accuracy, and reduced mechanical losses and inertia.
How do I choose the right built-in motor spindle? What factors should be considered regarding speed, torque, and cooling methods?
•Speed and Torque: Select a spindle that matches the speed and torque requirements of your machining process. High-precision, high-speed machining requires higher RPMs, while roughing or hard materials need higher torque.
•Cooling Method: Built-in motor spindles often require cooling (water or oil) to control thermal deformation, extend lifespan, and maintain precision.
•Spindle and Machine Compatibility: Ensure the spindle’s motor power, speed range, and control system (e.g., inverter/servo driver) are compatible with the machine.
What maintenance and servicing are required for a built-in motor spindle? What common issues or failures should be noted?
Bearing Lubrication and Cleaning: Proper bearing lubrication is essential for spindle lifespan and precision. Regularly check lubrication and prevent coolant or debris from entering.
Temperature and Cooling System: Ensure the cooling system (e.g., water cooling) functions properly before long-duration, high-load machining to prevent overheating and performance degradation.
Motor and Control Matching: Use correct inverter/driver settings to avoid electrical or mechanical failures caused by incorrect driving.
