CNC Machining
CNC Turning Parts
Rotational and cylindrical components — shafts, sleeves, bushings, and threaded parts — coordinated from manufacturing resources in China, with specifications and delivery confirmed per inquiry.
What Is CNC Turning?
CNC turning is a machining process in which the workpiece rotates against a stationary cutting tool on a lathe. It is the standard process for rotational geometries: stepped diameters, grooves, threads, bores, and tapered features produced in a single setup.
Jinjiuhui coordinates CNC turned parts through manufacturing resources in China. We are a trading and sourcing coordination company, not a factory — achievable tolerances, surface finishes, and size ranges depend on the part and the assigned resource, and are confirmed per inquiry.
Typical Turned Part Examples

Shafts & Pins
Stepped shafts, axles, dowel pins, and threaded studs with turned diameters and grooves.

Sleeves & Bushings
Sleeves, bushings, collars, and spacer rings with concentric outer and inner diameters.

Cylindrical Components
Round connectors, threaded fittings, nozzles, and other rotational parts with bores and threads.
