Personally, people's awareness of electric spindles is that they are an energy device with a wide range of applications. However, its integration techniques have not been well understood. Understand multiple techniques for integrating electric spindles.

(1) High speed bearing technique: Electric spindles are usually made of composite ceramic materials, which make them wear-resistant, heat-resistant, and have a longer service life than traditional bearings.

(2) High speed motor technique: Electric spindle is a product of the fusion of electric motor and spindle. The rotor of the electric motor is the rotating part of the main shaft. The electric spindle can be regarded as a high-speed electric motor, and the key technique is dynamic balancing at high speeds.

(3) Lubrication: Lubrication is a technique that requires regular and quantitative lubrication. If the lubrication is not in place, it will directly affect the utilization rate. If the amount of lubricating oil is controlled correctly each time, too little will not have a lubricating effect. When the bearing rotates at high speed, excessive heat will heat up due to the resistance of the oil;

(4) Cooling device: The heat dissipation of the electric spindle is very important, and usually requires the installation of a cooling device to maintain the temperature of the coolant;

(5) Built in pulse encoder: In order to achieve active tool changing and rigid thread tapping, the electric spindle is equipped with a pulse encoder to achieve correct phase angle control and coordinated feed;

(6) Active tool changing device: In order to be used in machining centers, the electric spindle is equipped with an active tool changing device, including disc springs, tool pulling cylinders, etc.

(7) The clamping method of high-speed cutting tools: well-known BT and ISO cutting tools have been proven to be unsuitable for high-speed machining. In this situation, high-speed cutting tools such as HSK and SKI have emerged;

(8) High frequency frequency inverter: High speed electric spindles require a high-frequency inverter to drive the built-in high-speed motor of the electric spindle in order to achieve the desired operating effect.

The electric spindle combines multiple techniques to improve its functionality, character, stable operation, and extended service life. The advancement of science and technology, as well as the acceleration of industrial production speed, have led to continuous reforms in its techniques, and significant progress in its functions and utilization.
