Produced in stainless steel by Aunov Tech, the CNC Machined V-Band Flange Ring is formed and machined on the same floor. On the product, the CNC machined part delivers the precise turned or milled geometry the assembly mounts to. Die work, machining and CMM inspection are all in-house, so first-article dimensions hold through volume batches on one production route.
Product overview
This metal ring is defined by, the draw ratio, corner radii and the faces that must stay flat, recorded on the inspection report for every batch.
Toolroom, presses and machining centres used on this metal ring operate on the same site, so a drawing change is absorbed in one step, and the die record stays with your part number.
From coil to finished part
Production of this metal ring is locked to one route: Machining starts from bar or plate and runs on CNC centres; cycle time and tool life are recorded per part number.
Process settings are archived with the part number, so nothing depends on the operator remembering.
Materials and surface finish
The standard stock list carries SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with carbon steel or stainless specified on the drawing for this metal ring.
Finish selection follows the working environment: electrophoresis, powder coating, anodising and zinc / nickel plating. It is fixed on the drawing for this metal ring, so repeat orders never reopen the question.
Route cards follow each quick-coupling hose fittings, batch through the shop, so the next run starts from the data that already worked. Deviations on the quick-coupling hose fittings, are reported before shipment rather than found on your assembly line.
Quality control
The factory operates with ISO 9001 certification: stock arrivals are checked against mill certificates, first-article geometry is confirmed on the CMM, and later batches follow the sampling plan agreed at approval. First articles of the quick-coupling hose fittings, are CMM measured, with threads gauged to class and diameters recorded. Functional testing – torque, leak or pressure – can be written into the plan, and the report is packed with the shipment.
Applications
This metal ring normally works inside industrial and appliance assemblies in both OEM and aftermarket supply.
The same metal ring is often run in more than one assembly, so the finish is chosen to cover the harshest of them, and the drawing stays common.
Customization and options
Frequently varied options
The options most often changed on this metal ring: material and coating for the duty, wall bands, flange forms, threads and bosses, closed ends and finishes matched to the working environment, and the batch pattern – prototype, pilot lot or scheduled production.
The quotation for this metal ring is explicit about what the die already covers, so you can see which options are free and which need new tooling. Tooling ownership for the quick-coupling hose fittings, is part of the written quotation.
Specifications
| Item | CNC Machined V-Band Flange Ring |
|---|---|
| Brand | AUNOV |
| Designing | Quotation reflects the real drawing: tolerances, finish and features are priced as specified. |
| Tooling | Die design and toolmaking stay in house, so die cost stays transparent, and first-article timing is measured from the tooling start date. |
| Samples | Any sample deviation is corrected before the first production batch is released. |
| Materials | Stock covers carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass; mill certificates and heat numbers accompany the first article. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; the agreed finish travels with the part number. |
| Processing | Turning, milling and drilling sequenced to minimise handling and re-chucking; in-process checks sit between stages, not only at the end. |
| Equipment | CNC turning centres with bar feeders and 3-/4-axis machining centres, with in-house toolmaking to keep dies and fixtures maintained. |
| Tolerance | +/-0.01 mm on critical bores, confirms at DFM stage; critical dimensions carry CMM data with the shipment. |
| Delivery terms | Standard terms FOB; DDP available for EU and US, with T/T and L/C accepted. |
Packing and shipment
For this metal ring, protection starts at the surface: interleaving, individual bags or trays are chosen by finish type, in sealed cartons on export pallets, with documents issued to your instructions.
