Aunov Tech manufactures the Stainless steel Machining parts in brass or stainless steel on a single production floor. Once installed, the CNC machined part carries the controlled features that forming alone cannot hold. Forming and machining share equipment, staff and batch records, so repeat orders stay aligned with the approved sample under one roof.
Product overview
The specification of this stainless steel component turns on, material grade, wall uniformity and thread position, recorded on the inspection report for every batch.
Toolroom, presses and machining centres used on this stainless steel component operate on the same site, so a drawing change is absorbed in one step, and the die record stays with your part number.
How it is manufactured
The process for this stainless steel component runs in a fixed sequence: Bar stock is sawn and then machined on CNC turning and milling centres; threads are single-pointed or rolled and seats bored in one setup where possible.
Route cards follow every order through the shop, and the same setup is reused on the next call-off.
Materials and surface finish
Everything is drawn from a fixed stock list: carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and the grade agreed for this stainless steel component is 304 / 316 stainless steel.
Coating and polishing are matched to the end use: zinc and nickel plating, chrome, anodising, powder coating and passivation. The agreed finish for this stainless steel component travels with the part number on every reorder.
Route cards follow each machining part batch through the shop, so the next run starts from the data that already worked. Any change to the machining part drawing is re-approved and re-verified before production continues.
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 production batches are inspected on a sampling plan. The machining part first article is CMM measured – threads gauged to class, diameters on the record. Torque, leak and pressure tests are available where the assembly needs them, with certificates included in the shipment file.
Applications
The stainless steel component sits in industrial and appliance assemblies for OEM and Tier-1 customers.
The same stainless steel component is often run in more than one assembly, so a single grade and coating can cover each application, and cost per piece stays at the volume tier.
Specifications
| Item | Stainless steel Machining parts |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – a manufacturability review comes back with the quotation; the approved drawing is kept as the controlled master. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so no tooling step is outsourced, and the charge is refundable against agreed volumes. |
| Samples | Prototype and pre-production samples are provided against the drawing, so the approved first article becomes the gauge reference, and later batches are gauged back to the signed sample. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass are held on site; mill certificates and heat numbers accompany the first article. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; alternatives quoted with the quotation, samples approved in writing. |
| Processing | Turn-mill machining, critical diameters finished in one setup; every stage is logged against your part number. |
| Equipment | CNC turning centres with bar feeders and 3-/4-axis machining centres; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.005 mm achievable on ground faces where the print demands it; capability is checked on the first article before the run continues. |
| Delivery terms | FOB Ningbo or Shanghai, T/T or L/C, with D/P accepted on repeat business; price breaks tie to annual volume. |
