Pyörimisprosessi

Pyörimisprosessi refers to a manufacturing method where material is removed from a workpiece while it rotates. This process is primarily used to create cylindrical or conical shapes, such as shafts, discs, and threaded components. The two main types of pyörimisprosessi are turning and milling.

Turning involves a stationary cutting tool that moves linearly against the rotating workpiece. The tool removes material in the form of chips, shaping the outer diameter, inner diameter, or face of the workpiece. Lathes are the machines commonly used for turning operations.

Milling, on the other hand, utilizes a rotating cutting tool that moves relative to a stationary or moving workpiece. The rotating cutter has multiple cutting edges that remove material as it rotates and advances. Milling machines are used for this process and can create a wide variety of shapes, including flat surfaces, slots, and complex contours.

Both turning and milling are subtractive manufacturing processes, meaning they start with a solid piece of material and remove unwanted portions to achieve the desired form. They are essential in many industries, including automotive, aerospace, and general manufacturing, for producing precise and functional parts. The choice between turning and milling depends on the desired geometry, material properties, and required tolerances.
