CNC lathes have some key requirements for feed transmission mechanisms, which mainly involve machine tool performance, accuracy and reliability. Here are some common requirements:

1. High precision: The CNC lathe feed transmission mechanism needs to provide high-precision position control to ensure that the CNC lathe can accurately execute the processing program. High-precision feed transmission helps achieve precise control of part dimensions.

2. High speed: CNC lathes usually need to complete processing tasks within a certain period of time, so the feed transmission mechanism needs to provide sufficient speed to improve production efficiency.

3. High rigidity: In order to reduce vibration and improve the rigidity of the machine tool, the feed transmission mechanism of CNC lathes should have sufficient rigidity to maintain the stability of the tool and workpiece. This helps improve processing quality and accuracy.

4. Quick response: The CNC lathe feed transmission mechanism needs to be able to quickly respond to changes in instructions from the CNC system to ensure immediate and accurate position adjustment. This is essential for achieving complex contours and high-speed cutting.

5. Adjustability: CNC lathes sometimes need to adjust the feed rate according to different processing requirements. Therefore, the feed transmission mechanism should have adjustable performance to meet the needs of different processing tasks.

6. Low wear: In order to maintain long-term stability and performance of CNC lathes, the feed transmission mechanism should be designed with a low-wear structure to extend its service life.

7. Low noise: The CNC lathe feed transmission mechanism should have low noise characteristics to provide a comfortable working environment, and for some applications, low noise can also help improve processing quality.

8. High reliability: The CNC lathe feed transmission mechanism is a key component of the CNC lathe, so it needs to have high reliability to ensure the stability and reliability of the production process.

9. Ease of maintenance: If the CNC lathe needs to be maintained or repaired, the feed transmission mechanism should be designed into an easy-to-maintain structure to reduce downtime.

10. Adapt to different working conditions: The CNC lathe feed transmission mechanism should have the ability to adapt to different working conditions and workpiece requirements to cope with diverse processing tasks.

Together, these requirements ensure that CNC lathes can process stably and efficiently under various process conditions. Manufacturers often consider a combination of these factors when selecting and designing feed drives to meet the needs of a specific application.
