The Custom Stainless Steel CNC Machined Rings and Fittings is produced by Aunov Tech from stainless steel, formed and finished under one roof. On the product, the CNC machined part delivers the precise turned or milled geometry the assembly mounts to. Drawing, cutting and measurement sit on one floor, which keeps tolerances consistent from sample to volume on one production route.
Product overview
This stainless steel fitting is defined by, the draw ratio, corner radii and the faces that must stay flat, recorded on the inspection report for every batch.
Die building, pressing and machining for this stainless steel fitting are all in house, so the route from print to sample stays short, with the tooling history retained in house.
How it is manufactured
Manufacturing runs on a controlled process path: Machining starts from bar or plate and runs on CNC centres; threads are single-pointed or rolled and seats bored in one setup where possible.
Every mold plate order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. The approved mold plate sample governs later runs, and any grade change is agreed in writing first.
Materials and surface finish
The standard stock list carries SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this stainless steel fitting runs in 304 / 316 stainless steel.
The surface treatment is picked to match the service conditions: polishing, zinc / nickel / chrome plating, anodising or powder coating. It is fixed on the drawing for this stainless steel fitting, so repeat orders never reopen the question.
The mold plate tooling and setup record is stored against the part number, so nothing depends on someone remembering. That record is what every mold plate reorder is built on, so nothing changes silently between shipments.
Quality control and inspection
Quality management is certified to ISO 9001: mill certificates cover every delivery of stock, the first article is CMM-measured against the print, and routine sampling keeps batches aligned with the first article. CMM first-article measurement of the mold plate covers diameters and gauges thread class. Tests for torque, leakage or pressure can be arranged when the service demands them, and the inspection report ships with each batch.
Applications
Typical installation of the stainless steel fitting is in industrial equipment and general assembly work for OEM and Tier-1 customers.
This stainless steel fitting is supplied to several positions in the same machine, so the finish is chosen to cover the harshest of them, without a second tooling round.
Customization and options
Options changed most often
Points customers normally tailor on this stainless steel fitting: material grade, wall band, flange shape, thread size and finish for the working environment, and the batch pattern – prototype, pilot lot or scheduled production.
The quote for this stainless steel fitting separates tooled options from new work, so the effect of a revision on price is clear up front. Repeat orders of the mold plate keep the same cost split.
Specifications
| Item | Custom Stainless Steel CNC Machined Rings and Fittings |
|---|---|
| Brand | AUNOV |
| Designing | The drawing is reviewed first; the agreed version then governs every batch. |
| Tooling | Progressive and drawing dies are designed and built in house, so a die can be re-cut against the approved drawing, and first-article timing is measured from the tooling start date. |
| Samples | Prototype and pre-production samples are provided against the drawing, so the approved first article becomes the gauge reference, and mass production is gated on that approval. |
| Materials | Standard stock: carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass; the final grade is fixed with the drawing review. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; the agreed finish travels with the part number. |
| Processing | Turning, milling and drilling sequenced to minimise handling and re-chucking; first articles verify the whole flow before the run is released. |
| Equipment | CNC turning centres with bar feeders and 3-/4-axis machining centres, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.01 mm on ground diameters, with GD&T taken from your print; dimensional reports accompany the first article. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, T/T or L/C, with D/P accepted on repeat business; each volume tier carries its own quoted price. |
Packing and shipment
For this stainless steel fitting, protection starts at the surface: each coating gets its own packing – interleaves, bags or trays, in sealed cartons on export pallets; shipping documents and carton marks follow your instructions.
