Aunov Tech builds this Aluminum CNC Machined Motor End Caps in aluminum, from coil or bar through to the finished surfaces. In the assembly, the motor end cover aligns the rotor through the machined bearing bore. Die work, machining and CMM inspection are all in-house, and a design change is re-sampled in one place without handing the part to another vendor.
Product overview
The specification of this aluminium cap turns on, material grade, wall uniformity and thread position, each measured at first article and gauged on production batches.
Forming, machining and finishing for this aluminium cap happen on one site, so a change of wall or hole does not restart the programme, and the approved sample is kept as the master.
How it is manufactured
The process for this aluminium cap runs in a fixed sequence: The part is machined from bar or plate on CNC lathes and mills; tight features are held in one setup so concentricity does not depend on re-chucking.
Repeat hex bushing orders are measured against the approved sample, so neither material nor finish drifts between lots. First article, drawing revision and material cert travel with each hex bushing batch.
Materials and surface finish
The standard stock list carries SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with aluminium specified on the drawing for this aluminium cap.
Finish selection follows the working environment: zinc and nickel plating, chrome, anodising, powder coating and passivation. It is fixed on the drawing for this aluminium cap, so repeat orders never reopen the question.
Repeat hex bushing orders are measured against the approved sample, so neither material nor finish drifts between lots. The signed hex bushing sample remains the reference and is kept with the job file.
Quality control and inspection
An ISO 9001 certified system governs production: material traceability starts with mill certificates, first articles are measured on a CMM, and every production run is inspected against the first-article report. On the motor end cover itself, bearing-bore size and spigot runout are measured at first article and gauged on production runs. Torque, leak and pressure tests are available where the assembly needs them, and the batch file carries the results.
Where the part is used
The aluminium cap sits in industrial machinery and equipment assemblies in both OEM and aftermarket supply.
This aluminium cap is supplied to several positions in the same machine, so a single grade and coating can cover each application, and the drawing stays common.
Customization and options
The options customers tune most
The parts of the print for this aluminium cap that get adjusted: material grade, wall band, flange shape, thread size and finish for the working environment, and whether orders run as prototypes, pilot lots or scheduled batches.
The quotation for this aluminium cap marks what the existing tooling can do, so you can see which options are free and which need new tooling. The hex bushing quote carries the tooling terms; nothing is implied.
Specifications
| Item | Aluminum CNC Machined Motor End Caps |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – samples are reverse-measured into a controlled drawing; the same drawing is used for every repeat order. |
| Tooling | Tooling is built and held under your part number, so die cost stays transparent, and first-article timing is measured from the tooling start date. |
| Samples | Sample and first article are the same discipline here: measured, reported, then approved. |
| Materials | 1050 / 3003 / 5052 / 6061 aluminium, 0.5-3.0 mm stock – temper matched to the forming depth or machining route of this cap. |
| 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; batch records are filed so a repeat order starts from approved data. |
| 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; finer bands confirmed from capability data before quoting. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, T/T with deposit and L/C for larger runs; price breaks tie to annual volume. |
Packing and shipment
Packaging protects the finished surfaces of this aluminium cap: each coating gets its own packing – interleaves, bags or trays, in sealed export cartons, palletised and marked as you direct.
