Custom CNC Turned Stainless Steel Hollow Cylinder Sleeve with External Thread & Mirror Polished Surface
This hollow cylindrical sleeve is manufactured by precision CNC turning. It features seamless hollow structure, precise external thread and mirror polished surface. Excellent corrosion resistance and high tensile strength make it suitable for fluid pipeline, pressure vessel and mechanical transmission assemblies.
| Parameter | Value |
|---|---|
| Processing Type | CNC Turning, Internal Boring, Thread Machining, Mirror Polishing, Deburring |
| Available Material | 304 Stainless Steel, 316L Stainless Steel |
| Tolerance | ±0.01 mm |
| Surface Finish | Mirror Polishing, Bright Polishing, Passivation |
| Drawing Format | STEP / IGES / 2D PDF |
| Application Scenario | Hydraulic pipeline, Pressure equipment, Mechanical transmission, Fluid handling system |
| Inspection Method | CMM, Thread Gauge, Micrometer, Roughness Tester |
| Production Range | Prototype, Small Batch & Mass Production |
This stainless steel hollow cylinder sleeve is precision machined on CNC lathe. The outer cylindrical surface, inner bore and external thread are completed in one clamping to guarantee concentricity and dimensional accuracy.
Chenrong Precision specializes in stainless steel turning parts with high surface requirements. Mirror polishing removes surface scratches and improves smoothness. Passivation treatment further enhances anti-rust performance. We can customize outer diameter, inner bore size, thread specification, total length and surface finish to match your engineering drawings.
We are experienced in turning long stainless steel tubular components. Our lathe equipment ensures good concentricity for long hollow parts. Every batch will inspect thread size, dimensional tolerance and surface roughness. We support sample trial and stable mass production for overseas industrial clients.
Q1: Can you customize different thread standards?
A1: Yes, we can produce metric, UNC, UNF and BSP threads according to your requirements.
Q2: What is the difference between 304 and 316L stainless steel for this sleeve?
A2: 316L provides better resistance to saltwater and chemical corrosion, while 304 is cost-effective for general indoor and normal wet environments.
Q3: Can we change the inner bore diameter and wall thickness?
A3: Absolutely, inner bore, wall thickness and overall length are fully customizable based on your drawings.
Q4: What roughness can mirror polishing achieve?
A4: Mirror polishing can reach Ra ≤0.08μm, suitable for high smoothness assembly and fluid flow requirements.
Q5: What is the lead time for mass order?
A5: Normally mass production lead time is 10-13 working days after sample confirmation.
