Stainless steel service scope
Stainless Steel CNC Machining Scope
KENDORIC supports stainless steel CNC machining projects for overseas buyers who need durable or corrosion-resistant custom parts made from drawings or CAD files. Typical stainless steel parts include shafts, sleeves, bushings, pins, fittings, brackets, housings, blocks, and precision components requiring thread, bore, surface finish, or inspection review. Before quotation, stainless grade, geometry, machining difficulty, tolerances, surface finish, threads, and inspection requirements can be reviewed early.
Stainless Steel Part Types
Shafts, sleeves, bushings, pins, fittings, brackets, blocks, housings, and corrosion-resistant custom parts.
Stainless Grade Review
Common grades such as 304, 316, 303, 17-4PH, or drawing-specified stainless alloys can be reviewed according to corrosion resistance, machinability, strength, surface finish, and inspection requirements.
Thread, Bore and Fit Review
Threads, bores, critical diameters, bearing fits, seal surfaces, grooves, and mating features.
Surface Finish and Inspection
Deburring, polishing, passivation where applicable, visible surfaces, inspection reports, and critical dimensions.
Material benefits
Why Buyers Choose Stainless Steel for CNC Parts
Corrosion Resistance
Useful when parts are exposed to moisture, cleaning, outdoor conditions, or corrosion-sensitive environments.
Strength and Durability
Suitable for stronger functional parts, load-bearing features, threads, pins, bushings, fittings, and wear-related components.
Precision Round Parts
Common for shafts, sleeves, bushings, pins, spacers, collars, fittings, and turned components.
Functional Surfaces
Used when bearing fits, seal surfaces, threaded features, or stable mechanical interfaces are important.
Machining review
Common Stainless Steel Machining Considerations and RFQ Notes
| Consideration | Why It Matters | RFQ Detail to Provide |
|---|---|---|
| Grade selection | Machinability, corrosion resistance, and strength vary by grade | Confirm the stainless grade or describe the working environment |
| Critical diameters | Shafts, sleeves, bushings, and pins often depend on fit control | Mark fit dimensions, tolerance class, and mating parts if relevant |
| Threads and grooves | Tool access and finish can affect function | Provide thread standards, groove geometry, and inspection needs |
| Surface finish | Stainless parts may need functional or appearance-related surfaces | Specify finish target, deburring needs, and visible surfaces |
| Heat and tool load | Stainless machining can be slower and more demanding | Share geometry early, especially deep holes, thin walls, or tight features |
| Inspection points | Critical dimensions should be checked with suitable tools | Identify key dimensions, datum references, and report needs |
Typical components
Common Stainless Steel Part Types
Stainless Shafts and Sleeves
Critical diameters, runout, concentricity, bearing fits, and surface finish.
Bushings, Pins and Spacers
OD/ID tolerances, length, chamfers, wear surfaces, and assembly fit.
Fittings and Threaded Parts
Thread standards, sealing surfaces, grooves, bores, and deburring requirements.
Milled Stainless Parts
Brackets, blocks, plates, housings, clamps, and parts needing slower machining or inspection review.
Dimensional review
Stainless Steel Tolerances, Finish and Inspection
Machining Difficulty
Stainless steel can require slower machining, tool access review, heat control, and careful feature planning.
Critical Dimensions
Threads, bores, bearing fits, seal surfaces, critical diameters, and alignment features should be marked clearly.
Finish and Inspection
Surface roughness, deburring, passivation where applicable, polishing, visible surfaces, and report expectations should be clarified early.
Quick material check
Stainless Steel vs Aluminum: Quick Material Check
Stainless steel is usually selected for corrosion resistance, strength, wear resistance, and durable functional surfaces. Aluminum may be better when lower weight, faster machining, or anodizing appearance is more important. If the material is not finalized, send the drawing and part function for review.
