The main drive and feed drive of CNC lathes play a vital role in the performance and accuracy of the machine. They are the two important motion systems of the machine, including the spindle system, servo motor system, drive system and control system. Understanding their working methods and characteristics can help us better understand the operating principles of CNC lathes and choose the CNC lathe that best suits our work needs. Let’s take a look at these two transmission systems with you.
Spindle system
The spindle system is usually the most important core part of a CNC lathe. It drives the rotation of the workpiece through a motor and transmission mechanism to achieve precision machining. In general, grinding spindle dynamic balancing must meet extremely high standards. The dynamic balance of the spindle reaches the standard, making the turning work soft and smooth, and the surface of the machined parts is smooth and the precision is high. At the same time, the spindle system also has an important impact on the cutting capabilities of CNC lathes.
The spindle transmission system usually takes gears as the core, which can achieve different speed selections and cutting forces in processing methods. Generally, the spindle transmission of CNC lathes adopts hydraulic or electric linear transmission. The wider speed range and higher precision make the spindle suitable for tools of various specifications and requirements.
Feed drive system
The feed transmission system is responsible for driving the lathe bed and the linear movement of the workpiece during the machining process. Servo motors are usually used to directly drive the worktable, which maximizes processing efficiency while ensuring accuracy. Similar to the spindle system, the feed transmission system can also meet different processing needs through different driving methods and sensors.
* Hydraulic transmission method: This method has higher transmission power and is commonly used when processing large parts;
* Servo transmission method: This method is more efficient. While ensuring processing accuracy, the machine has higher production efficiency and stability, and has a wide range of applications.
The main transmission and feed transmission of a CNC lathe are the two core parts of the CNC lathe and play a vital role in the performance and accuracy of the machine. Understanding its working methods and characteristics can enable us to better choose the CNC lathe that best suits our work needs.
