High-Quality CNC Machined Turning Parts for Your Project

CNC TURNING · SECONDARY MACHINING · DRAWING-BASED PRODUCTION

Custom CNC turned parts built around fit, runout and assembly requirements

Hongming Sheng manufactures shafts, bushings, sleeves, pins, spacers, threaded fittings and other rotational components according to customer drawings, 3D files or approved samples.

We support prototypes, low-volume builds and repeat production, with engineering review before machining and inspection based on the dimensions that matter to part function.

CNC Turning in Production

Turning and Secondary-Machining Capabilities

External Features

OD turning, facing, shoulders, tapers, grooves, chamfers, external threads and project-dependent knurling.

Internal Features

Drilling, boring, reaming, counterbores, internal grooves and internal threads where geometry permits.

Combined Operations

Secondary milling for flats, slots, wrench features, radial holes and other non-rotational details.

Materials and Finishing Options

Common Materials

Aluminum alloys
Stainless steels
Carbon and alloy steels
Brass and copper
Engineering plastics
Titanium, subject to project review

Finishing Is Reviewed With the Machining Plan

Options may include anodizing, passivation, plating, black oxide, bead blasting, polishing and other specified finishes. Coating build-up, masking areas, cosmetic surfaces and post-finish dimensions should be identified before production.

Critical Controls for Turned Components

Fit and Geometry

Diameters, fits and mating lengths
Concentricity or coaxial relationships
Total runout and face runout
Datum structure and shoulder locations

Threads and Surfaces

Thread standard, class and gauge method
Surface roughness where function requires it
Edge breaks, burr limits and groove details
Cosmetic and finish-masking requirements

Inspection Methods

Micrometers and bore gauges
Pin, plug and thread gauges
Indicators for runout checks
Optical or CMM inspection where suitable

Tolerance note: achievable tolerances depend on diameter, length, material, geometry, workholding, secondary operations, surface treatment and the agreed inspection method. Mark critical dimensions, fits, runout and datum relationships clearly on the drawing so they can be reviewed before quotation.
