The use of electric spindles in CNC vertical lathes brings many benefits, mainly reflected in the following aspects:

1. Improve the dynamic response speed and working accuracy of the spindle: CNC vertical lathe electric spindle eliminates belts, pulleys, gears and other links, greatly reducing the rotational inertia of the main drive, thus improving the dynamic response speed and working accuracy of the spindle. In addition, the high-speed characteristics of the electric spindle (the speed can reach more than 10,000r/min) further enhance its processing capabilities.

2. Solve the problem of vibration and noise: The CNC vertical lathe uses an electric spindle structure to completely solve the vibration and noise problems of belts and pulleys when the spindle is running at high speed, making the working environment quieter and also helping to improve processing accuracy.

3. Simplify machine tool design and facilitate spindle positioning: The CNC vertical lathe electric spindle has a compact structure, light weight, and small inertia, which not only simplifies machine tool design but also facilitates spindle positioning. This design feature of CNC vertical lathe makes the machine tool more flexible and efficient.

4. Improve servo accuracy: The combination of CNC vertical lathe electric spindle and linear motor technology eliminates the intermediate transmission link of the ball screw, eliminates transmission gaps, has small motion inertia, and has good system rigidity, thus greatly improving servo accuracy. .

5. Wide range of processing: CNC vertical lathes using electric spindles can process parts with complex shapes without the need for complex tooling. In addition, CNC vertical lathes can also process complex surfaces that are difficult to process with conventional methods, and can even process some processing parts that cannot be observed.

6. Reduce costs and improve reliability: CNC vertical lathe electric spindles make the components of CNC machine tools more professional and large-scale, reduce costs, simplify the structure, and improve the reliability of machine tools.

To sum up, the use of electric spindles in CNC vertical lathes not only improves processing accuracy and efficiency, but also reduces costs and enhances the reliability of machine tools, making it widely used in aerospace, shipbuilding, mold and other processing industries.
