Sisäsorvaus

Sisäsorvaus is a machining process used to enlarge or finish a hole in a workpiece. It is a type of internal machining where a rotating workpiece is held in a chuck or collet, and a cutting tool moves linearly to remove material from the inner diameter. This process is essential for achieving precise internal dimensions, smooth surface finishes, and specific geometric features within a bore.

The tools used in sisäsorvaus are typically single-point cutting tools with specific geometries designed for internal cutting. These tools can be mounted in a turret or a tool post, and their depth of cut and feed rate are carefully controlled by the machine operator or a CNC program. Common materials that undergo sisäsorvaus include various metals like steel, aluminum, and brass, as well as plastics and composites.

Sisäsorvaus is employed in a wide range of applications across different industries. It is crucial in the manufacturing of engine components, hydraulic and pneumatic cylinders, bearings, and various shafts requiring precise internal diameters. The process allows for the creation of features such as tapers, grooves, and threads on the internal surface of a workpiece. The accuracy and surface quality achieved through sisäsorvaus are critical for the proper functioning and longevity of many mechanical assemblies.
