Ball screws are used in a wide range of applications in machine tools, where they are typically used to convert rotary motion into linear motion for positioning, movement and machining of workpieces on the machine. The following are some of the main applications of ball screws in machine tools:

1. CNC machine tools: In CNC machine tools, ball screws are used to transfer motion and control the positioning and movement of workpieces in the X, Y and Z axes. This precision linear transmission allows CNC machine tools to realize high-speed, high-precision machining operations.

2. Table and Sliding Table: Ball screws can be used to control the movement of a table or sliding table on a machine tool, enabling accurate positioning and machining of the workpiece.

3. Spindle feed: In some machine tools, ball screws are also used to control the feed movement of the spindle, realizing the automatic feeding of the workpiece.

4. Servo drive system: Ball screws are usually used in conjunction with servo motors and control systems to form the drive system of the machine tool. By controlling

the rotation of the ball screw, precise position control and motion control can be realized, so as to complete complex machining tasks.

5. Automatic tool changer system: some machine tools are equipped with automatic tool changer system, ball screws can be used to control the automatic change of tools to improve the machining efficiency and flexibility of the machine tool.

Overall, the application of ball screws in machine tools can improve machining accuracy, machining efficiency and automation level, is one of the indispensable key components of modern machine tools.
