This Brass CNC Turned Fittings and Inserts is an Aunov Tech production part in brass, quoted and built to customer print. Once installed, the CNC machined part delivers the precise turned or milled geometry the assembly mounts to. One production floor covers forming, finishing and inspection, and a design change is re-sampled in one place under one roof.
Product overview
The critical features of this brass fitting are, material grade, wall uniformity and thread position, audited against the approved sample at each production release.
The press shop and machine shop that make this brass fitting share one floor, which keeps the sample loop inside our own schedule, and the approved sample is kept as the master.
How it is manufactured
Manufacturing runs on a controlled process path: Bar stock is sawn and then machined on CNC turning and milling centres; tight features are held in one setup so concentricity does not depend on re-chucking.
Batch records for the quick-connect coupling sockets, are filed against the part number, so process settings are reused instead of re-invented. First article, drawing revision and material cert travel with each quick-connect coupling sockets, batch.
Materials and finishing
The standard stock list carries carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper with this brass fitting costed in H62 brass.
Coating and polishing are matched to the end use: polishing, zinc / nickel / chrome plating, anodising or powder coating. The choice is recorded on the drawing for this brass fitting, so the decision never has to be made twice.
Production is compared with the approved sample every run, so neither material nor finish drifts between lots.
Quality control and inspection
Quality management is certified to ISO 9001: certificates verify each incoming batch of material, the CMM measures the first article dimension by dimension, and run inspections follow an agreed sampling plan. First-article inspection of the quick-connect coupling sockets, runs on the CMM: thread classes gauged, diameters logged. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the inspection report ships with each batch.
Where the part is used
The brass fitting is fitted into industrial equipment and general assembly work for customers who own the drawing and the tooling.
The same brass fitting is often run in more than one assembly, so one approved version covers the whole range, and approvals carry across programmes.
Customization and options
Options buyers most often change on this quick-connect coupling sockets,
The options most often changed on this brass fitting: material grade, wall band, flange shape, thread size and finish for the working environment, with orders run as prototypes, pilot lots or scheduled call-offs.
Each quote for this brass fitting states which variations are already tooled, so you are not charged twice for a feature the die already makes. The quick-connect coupling sockets, quote lists quantities with the corresponding price breaks.
Specifications
| Item | Brass CNC Turned Fittings and Inserts |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – DFM notes are returned before any tooling is cut; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so the die charge appears as its own quotation line, and maintenance is tracked against the part number. |
| Samples | Pre-production samples come with a full inspection report, so the part is proven before it is made in volume, and later batches are gauged back to the signed sample. |
| Materials | H62 / H65 brass, 0.8-4.0 mm, selected for conductivity, fine surface detail and corrosion resistance on this fitting. |
| Surface finish | Natural, plated or coated – the print decides, and the agreed finish is logged; masking and laser marking available where needed. |
| Processing | Turn-mill machining, critical diameters finished in one setup; every stage is logged against your part number. |
| Equipment | 12 CNC turning centres with automatic bar feeders; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.01 mm on ground diameters, with GD&T taken from your print; 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; sea or air freight is quoted to your door. |
Packaging and delivery
The finish on this brass fitting dictates how it is packed: interleaving, bagging or tray packing is matched to the surface, then cartons are sealed and palletised, with marks and documents as you specify.
