Millturn

Millturn refers to a type of multi-axis machine tool that combines the capabilities of both milling and turning operations. These machines are highly versatile and can perform complex machining tasks on a single workpiece without requiring it to be moved to different machines. A typical millturn center integrates a CNC lathe with a milling spindle.

The turning function is achieved through a rotating workpiece held in a chuck or between centers, while a stationary cutting tool removes material. The milling function utilizes a rotating cutting tool, such as an end mill or drill, to machine features on the workpiece, which can be stationary or also rotating. This dual functionality allows for the creation of intricate geometries, including complex curves, profiles, and internal/external threads, all within a single setup.

Millturn machines are often equipped with multiple axes of motion, typically three linear axes (X, Y, Z) and two rotary axes (B and C), enabling them to access the workpiece from various angles. This high degree of flexibility makes them ideal for producing complex parts in industries such as aerospace, automotive, and medical device manufacturing, where precision and efficiency are paramount. By reducing the need for multiple setups and transfers, millturn machining significantly shortens lead times and minimizes potential errors.
