sorvaaminen

Sorvaaminen is a machining process used to shape materials, typically metal, wood, or plastic, by rotating the workpiece against a cutting tool. The tool is held stationary or moves along a path parallel to the axis of rotation, removing material to create a desired shape, often cylindrical. This technique is fundamental in manufacturing for producing parts with precise dimensions and smooth surfaces.

The process is performed on a machine called a lathe. Lathes come in various types, including engine lathes, turret lathes, and CNC (Computer Numerical Control) lathes. The basic operation involves securing the workpiece in a chuck or between centers, which then spins at a controlled speed. The cutting tool, usually a single-point tool made of hardened steel or carbide, is brought into contact with the rotating material. As the workpiece turns, the tool shaves off thin layers of material, gradually forming the workpiece to the intended dimensions.

Common operations performed on a lathe include turning (creating external cylindrical surfaces), facing (creating flat surfaces perpendicular to the axis of rotation), boring (enlarging an existing hole), and threading (cutting screw threads). Sorvaaminen is crucial for producing components like shafts, axles, screws, and decorative elements. The precision and versatility of this machining method make it indispensable in industries ranging from automotive and aerospace to woodworking and prototyping.
