Turning lathes working with computer support are known as CNC lathe. There are two main axes in CNC lathe. These axes are; It is the Z-axis that enables the cutter to move the workpiece longitudinally and the X-axis that enables the cutter to advance in diameter. CNC machines with more processing capabilities have C axis as well as X and Z axes. Milling operations are also performed on the part on a C-axis lathe. The C axis can be at positions 0 ° - 30 ° - 45 ° - 60 ° - 90 ° to the workpiece. Its working principle is like a vertical milling machine.

The cutters used in the C axis rotate around their own axis as in the milling machine. The workpiece is then fixed at the desired angle. The cutter processes the part at a certain speed and advance at the desired angle. Without the need for another machine, only the operations of milling and machining center benches can be completed on the lathe. The part is manufactured by saving both time and labor.

The work and operations performed on the CNC lathe are as follows;
• Cylindrical turning
• Profile turning
• Face turning
• Opening the channel
• Threading
•Hole punch
• Threading with a tap
• Reaming
• Hole enlargement
• Grooving into the hole
• Grooving the forehead of the part
• caterpillar
• Curve and chamfer operations etc.
