Carbon steel turned parts are metal parts manufactured through turning. Their "components" typically refer to the geometric structural elements and functional characteristics that make up the part, rather than independent physical components. These structural elements are designed to serve specific mechanical functions, such as transmission, connection, sealing, or support.
Outer cylindrical surface: The external rotating surface of a part, used for mating with other components or as a support surface, such as bearing seats or sealing positions on shaft parts.
Inner hole (through hole or blind hole): Used for mounting other parts (such as shafts or pins) or to provide a fluid passage; commonly found in sleeve and flange parts.
End Face: The flat surfaces at both ends of a part, used for axial positioning, sealing, or assembly contact, requiring control over flatness and perpendicularity.
Thread: Including external and internal threads, used for fastening connections such as bolts, joints, and adjusting rods, and can be machined in metric, imperial, or special pitches.
Conical and spherical surfaces are used for sealing, centering, or special motion transmission, such as conical valve cores and ball joints. They require CNC interpolation functionality.
Chamfers and fillets are machined at edges to facilitate assembly, deburr removal, reduce stress concentration, and improve part fatigue life.
Keyways and flat sections (requiring subsequent milling) are not directly machined but are often designed as part of the overall structure on shaft parts for torque transmission.
Groove and Relief Groove: Annular grooves machined on the outer diameter or inner hole, used to accommodate sealing rings (such as O-rings), retaining rings, or to provide retraction space for cutting.
