This Stainless Steel CNC Machined Valve Nipples is an Aunov Tech production part in stainless steel, quoted and built to customer print. In operation, the CNC machined part carries the controlled features that forming alone cannot hold. The same floor forms, machines and inspects the part, so repeat orders stay aligned with the approved sample under one roof.
Product overview
The specification of this stainless steel valve turns on, the draw ratio, corner radii and the faces that must stay flat, re-checked whenever the drawing is revised.
Die building, pressing and machining for this stainless steel valve are all in house, so a change of wall or hole does not restart the programme, and every step is logged against the part number.
From coil to finished part
The route for this stainless steel valve is fixed and repeatable: Bar stock is sawn and then machined on CNC turning and milling centres; deburring and edge blending complete the operation before inspection.
Route cards follow each stepped shaft batch through the shop, so the next run starts from the data that already worked. Deviations on the stepped shaft are reported before shipment rather than found on your assembly line.
Materials and surface finish
Base materials in stock: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with this stainless steel valve costed in 304 / 316 stainless steel.
Coating selection follows the duty – indoor, outdoor or under-hood: electrophoresis, powder coating, anodising and zinc / nickel plating. The choice is recorded on the drawing for this stainless steel valve, so the decision never has to be made twice.
Batch records for the stepped shaft are filed against the part number, so process settings are reused instead of re-invented. Deviations on the stepped shaft are reported before shipment rather than found on your assembly line.
Quality control and inspection
An ISO 9001 certified system governs production: certificates verify each incoming batch of material, the first article is CMM-measured against the print, and every production run is inspected against the first-article report. First articles of the stepped shaft are CMM measured, with threads gauged to class and diameters recorded. Tests for torque, leakage or pressure can be arranged when the service demands them, with certificates included in the shipment file.
Applications
This stainless steel valve normally works inside pump, valve and fluid handling assemblies across automotive, appliance and industrial programmes.
This stainless steel valve is supplied to several positions in the same machine, so one approved version covers the whole range, and approvals carry across programmes.
Options and variations
Common variation points across this stepped shaft family
Design freedom covers material (carbon steel, stainless, aluminum, brass), the finish for the environment, thread classes, seat finishes, milled features, cross-holes and plating or anodizing to the print, and lot sizing from prototypes to call-off.
Each variation is priced with its tooling effect made visible, making the cost of each choice clear before you commit.
Specifications
| Item | Stainless Steel CNC Machined Valve Nipples |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – DFM notes are returned before any tooling is cut; the agreed version governs every later batch. |
| Tooling | Tooling is built and held under your part number, so a die can be re-cut against the approved drawing, and the die remains dedicated to your part. |
| Samples | Samples are issued for approval before the run, so the part is proven before it is made in volume, and later batches are gauged back to the signed sample. |
| Materials | Stainless 304 and 316L, pickled and annealed, 0.5-3.0 mm nominal wall – one grade chosen for corrosion duty and formability of this valve. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; alternatives quoted with the quotation, samples approved in writing. |
| Processing | CNC turning from bar or billet, concentricity held across operations; batch records are filed so a repeat order starts from approved data. |
| Equipment | Bar-fed CNC turning centres plus 3- and 4-axis machining centres; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.01 mm on machined faces, +/-0.05 mm on formed details; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | FOB with DDP offered for EU and US addresses; payment T/T or L/C, freight quoted to destination. |
Packing and shipment
Finish comes first when packing this stainless steel valve: interleaves, polybags or formed trays are selected according to the coating, in sealed cartons on export pallets; shipping documents and carton marks follow your instructions.
