What is Back Spindle on CNC Lathe Machine?

The back spindle on a CNC (Computer Numerical Control) lathe machine is a secondary spindle located behind the main spindle. It is also sometimes referred to as the sub-spindle or sub-turret. The back spindle can be programmed to perform a range of operations on a workpiece, including drilling, tapping, and boring.

The main purpose of the back spindle is to allow for the machining of the workpiece on both ends without the need for manual intervention or repositioning. This enables the lathe to produce more complex parts with greater accuracy and efficiency.

When the back spindle is used in conjunction with the main spindle, the lathe is able to perform a variety of operations, such as turning, milling, drilling, and tapping, on the workpiece. This ability to perform multiple operations without having to remove and reposition the workpiece significantly reduces cycle times and increases productivity.

Overall, the back spindle is a crucial component of a CNC lathe machine, allowing for increased flexibility and precision in the manufacturing process.
