Choosing a CNC lathe or a CNC turning center depends solely on the particularities of your project. If all you have to do is turn cylindrical parts, then a CNC lathe will do. Any type of complex machining that requires processes such as milling and drilling would be best suited for a CNC turning center. Evaluate your machining needs to identify the CNC machine that best suits your requirements.
What is the turning process, and how is it performed on a CNC lathe?
Turn is a subtractive manufacturing process where material is removed from a workpiece to form a given shape. On a CNC lathe, the workpiece is rotated against a cutting tool, which removes material to the final dimension. The process is relatively fast and allows for the tightest control on the dimension and finish of the part being manufactured.
