Mill Turning vs Milling and Turning
Milling and turning are individual CNC machining processes, each with its unique characteristics and applications. However, the combination of these processes in mill-turn machining introduces an approach that offers advantages over separate milling and turning operations. Mill turning is characterized by its integration of milling and turning capabilities within a single-machine setup. This process efficiently handles complex parts by simultaneously performing milling and turning operations.
When milling and turning are executed separately, the machining operations are divided between dedicated machines. Milling involves a rotating cutting tool removing material while turning centers around a rotating workpiece with a stationary cutting tool. While effective for specific operations, this approach may necessitate transferring workpieces between machines, leading to increased setup and handling times. In CNC lathe machining and turning, the workpiece is held in place by a chuck and rotated at high speeds while the cutting tools are brought into contact with the workpiece to remove material and create the desired shape.
The choice between mill turning and separate milling and turning processes depends on the project's requirements. Mill turning stands out for its efficiency in handling complex parts, minimizing setup times, and offering a consolidated approach to machining operations.
