As for the feed transmission system of a CNC lathe, it is mainly a system that drives the tool holder (tool) to move precisely along the X-axis (radial) and Z-axis (axial), and its main function is to determine the machining accuracy and surface quality of the workpiece. Today, our CNC lathe manufacturer will explain in detail the main components and related functions of the CNC lathe feed transmission system.
1. Feed servo motor: Each motion axis (X-axis, Z-axis) is driven by an independent AC servo motor. Servo motors are renowned for their excellent response speed, control accuracy, and stability.
2. Transmission mechanism: Convert the rotational motion of the servo motor into precise linear motion of the tool holder.
Ball screw pair: This is the most essential and commonly used component. It is transmitted through balls between the screw and nut, with low friction, high efficiency, high precision, and strong reversibility.
Coupling/synchronous belt: used to connect servo motors and ball screws.
3. Guide rail: supports and guides moving parts (such as tool holders, tailstock) to move along precise paths. Common ones include:
Linear guide rail: low friction coefficient, sensitive motion, high positioning accuracy.
Sliding guide rail: With strong load-bearing capacity and good seismic resistance, it is commonly used in heavy-duty machine tools.
The above is the main composition and related functions of the feed transmission system of CNC lathes. We hope that the above explanation can be helpful for everyone when using CNC lathes in the future.
