Turning service scope
What CNC Turning Services Cover
KENDORIC supports CNC turning projects for overseas buyers who need shafts, sleeves, bushings, pins, fittings, spacers, collars, and other round components made from drawings or CAD files. Before quotation, we review diameter tolerances, bores, threads, grooves, runout, surface finish, material, secondary operations, and inspection requirements so unclear items can be clarified early.
Turned Part Types
Shafts, sleeves, bushings, pins, fittings, spacers, collars, and other round components.
Diameter and Bore Review
ODs, IDs, shoulders, grooves, bores, fits, thread details, and mating surfaces.
Runout and Concentricity Review
Concentricity, runout, bearing fits, seal surfaces, and alignment-related features.
Finish and Inspection Review
Surface roughness, thread gauges, bore inspection, chamfers, edge breaks, and report expectations.
Round components
CNC Turning for Round Components
CNC turning is suitable for cylindrical or rotational parts with outside diameters, bores, shoulders, grooves, tapers, threads, chamfers, and precision fit surfaces. Some turned parts may also require secondary milling, drilling, tapping, flats, cross holes, heat treatment, coating, or marking.
Shafts and Stepped Shafts
Round components with shoulders, fits, grooves, threads, and alignment surfaces.
Sleeves and Bushings
Parts where inside diameter, outside diameter, wall thickness, and concentricity matter.
Pins and Spacers
Components used for location, spacing, alignment, or controlled assembly fits.
Fittings and Connectors
Threaded or bored parts with sealing surfaces, grooves, and wrench features.
Parts with Secondary Features
Turned components requiring flats, cross holes, slots, milling, drilling, or tapping.
Buyer reference
Common Turned Parts and Critical RFQ Details
| Turned Part Type | Critical RFQ Details |
|---|---|
| Shafts | Bearing fits, runout, shoulder locations, threads, surface finish, and heat treatment if required. |
| Sleeves and bushings | Inside diameter, outside diameter, wall thickness, concentricity, and wear or fit requirements. |
| Pins and spacers | Diameter tolerance, length, chamfers, material, and whether the part is used for alignment. |
| Fittings and connectors | Thread standard, sealing surfaces, grooves, bores, and finish requirements. |
| Parts with secondary features | Cross holes, flats, slots, milled features, and secondary inspection points. |
Material options
Materials for CNC Turning
Aluminum Turning
Suitable for lightweight shafts, spacers, sleeves, fittings, and parts requiring good machinability or anodizing.
Stainless Steel Turning
Used for corrosion-resistant or stronger turned parts, with closer review of machining time, surface finish, and inspection needs.
Carbon Steel Turning
Suitable for mechanical shafts, pins, spacers, collars, and parts where strength, heat treatment, or cost balance matters.
Engineering Plastics
Used for lightweight, low-friction, insulating, or wear-related turned components depending on function.
Dimensional review
Turning Features and Dimensional Review
Diameter and Fit Control
OD/ID tolerances, bearing fits, seal fits, press fits, sliding fits, and mating components.
Runout and Concentricity
Relationships between bores, outside diameters, shoulders, and rotating or alignment features.
Threads, Grooves and Shoulders
Thread standards, groove width/depth, shoulder locations, chamfers, and edge breaks.
Post-processing
Surface Finish and Secondary Operations
Surface finish may be important for turned parts that slide, seal, rotate, or assemble with other components. Secondary operations such as cross drilling, milling flats, keyways, tapping, knurling, heat treatment, plating, coating, laser marking, or deburring should be included in the RFQ because they affect setup, cost, lead time, and inspection.
