Aunov Tech manufactures the Aluminum Threaded CNC Machined Sleeve in aluminum on a single production floor. In duty, the CNC machined part provides the finished surfaces, threads and seats the mating parts locate on. The same floor forms, machines and inspects the part, keeping first-article quality through scheduled runs with no third party in the loop.
Product overview
This aluminium sleeve is defined by, material grade, wall uniformity and thread position, recorded on the inspection report for every batch.
Forming, machining and finishing for this aluminium sleeve happen on one site, so a drawing change is absorbed in one step, with process data archived for repeat orders.
How it is manufactured
Production follows a defined route: Bar stock is sawn and then machined on CNC turning and milling centres; in-process gauging runs alongside the machines on longer batches.
Every stepped shaft order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. First article, drawing revision and material cert travel with each stepped shaft batch.
Materials and finishing
The standard stock list carries cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with this aluminium sleeve costed in aluminium.
Coating and polishing are matched to the end use: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. The agreed finish for this aluminium sleeve travels with the part number on every reorder.
Every stepped shaft order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. Deviations on the stepped shaft are reported before shipment rather than found on your assembly line.
Quality control and inspection
The factory operates with ISO 9001 certification: incoming material is verified against mill certificates, the CMM measures the first article dimension by dimension, and later batches follow the sampling plan agreed at approval. For the stepped shaft, first articles are CMM measured and threads are gauged to class. Functional testing – torque, leak or pressure – can be written into the plan, with certificates included in the shipment file.
Typical applications
This aluminium sleeve normally works inside industrial and appliance assemblies in volume programmes as well as aftermarket supply.
One part number for this aluminium sleeve frequently serves several assemblies, so a single grade and coating can cover each application, and cost per piece stays at the volume tier.
Customization and options
What customers usually vary
Points customers normally tailor on this aluminium sleeve: grade and finish for the environment, wall thickness bands, flange and rim forms, threads, bosses and closed ends, and whether the programme starts as a sample or a full release.
Options for this aluminium sleeve already covered by the die are shown on the quote, so the effect of a revision on price is clear up front. The stepped shaft is frozen against the current revision until a written change is raised.
Specifications
| Item | Aluminum Threaded CNC Machined Sleeve |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – samples are reverse-measured into a controlled drawing; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Tooling is built and held under your part number, so a die can be re-cut against the approved drawing, and first-article timing is measured from the tooling start date. |
| Samples | Samples are issued for approval before the run, so the part is proven before it is made in volume, and production starts only after your written sign-off. |
| Materials | Carbon steel, 304 / 316 stainless, aluminium and brass are all held in stock; material substitutes are proposed only with your written approval. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; the agreed finish travels with the part number. |
| Processing | Bar-fed turning with milled features completed in the same clamping; first articles verify the whole flow before the run is released. |
| Equipment | Bar-fed CNC turning centres plus 3- and 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; 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. |
Packaging and delivery
The packing method protects the surfaces of this aluminium sleeve: each coating gets its own packing – interleaves, bags or trays, in sealed cartons on export pallets, with documents issued to your instructions.
