We machine the Honda aluminum wheel 42700-S5N-A91 pattern from 6061-T6, 7075 or ADC12 on 5-axis centers. Bolt circle, hub bore, offset and spoke profile held to ±0.005 mm, then finished and 100% inspected before shipment.
Most of these show up after the first article, not before.
A hub bore and bolt circle machined on separate setups drift out of concentricity. The wheel balances on the machine and vibrates on the bike. Runout has to be controlled in one fixturing, not averaged across three operations.
Deep pockets between spokes are where a cutter deflects. Long reach, light passes, and the wall comes out 0.2 mm thin in the middle of the pocket. That is a fatigue crack waiting for a pothole.
A bowed mounting face clamps against the hub with a gap. Torque looks correct on the wrench. The wheel walks under braking and the lug seats wear into the rim.
Bare machined aluminum oxidizes. A coating applied over a contaminated surface blisters at the bead seat. Road salt finds every edge that was not prepped before anodizing.
The wheel is a rotationally symmetric part with a strict functional axis. Treat it that way.
We clamp the blank on the hub face and machine the center bore, the bolt circle, and the mounting face without releasing the part. Concentricity comes from the spindle, not from re-fixturing. On the 5-axis centers the table rotates the part through the spoke windows so the tool stays short and rigid.
For a Honda aluminum wheel 42700 replacement or a custom pattern, the critical stack is bore to bolt circle to mounting face. Get that stack right and the wheel seats flat on the hub the first time.
Spoke windows are the hard part. We rough them with a smaller stepover and leave 0.3 mm for the finishing pass, then take that finish cut at full depth so the wall thickness stays uniform around the window. Thin walls move when you push them. We would rather spend cycle time than scrap a set.
Material choice follows the load case. 6061-T6 is the default for street wheels: good strength, machines clean, takes anodizing evenly. 7075 gives more fatigue strength where the spoke meets the rim, at the cost of a slower cut and a less forgiving weld. ADC12 castings are machined to final dimensions when the customer supplies a near-net blank.
Pick the row that matches what you actually need delivered.
| Situation | Route | What you get |
|---|---|---|
| One-off replacement wheel | 3-axis mill + lathe | Bore, PCD and face machined and inspected |
| Custom spoke pattern, small batch | 5-axis machining | Spoke windows cut in one setup, no re-fixturing |
| Near-net casting to finish | Mill-turn center | Cast blank finished to drawing dimensions |
| Weight-driven redesign | 5-axis + FEA review | Wall thickness varied by load path, not by eye |
Wheel work rarely travels alone. These are the processes we run in-house.
16 simultaneous 5-axis centers for spoke windows, hub bores and one-setup datuming on complex geometry.
16 mill-turn centers handle hub faces, bead seats and diameters that need to be turned true to the bore.
One prototype or a short run before you commit to tooling. Same inspection reports as production.
Anodizing in clear, color and hardcoat; powder coating; bead blasting; brushing; laser marking from 1.5 mm character height.
ADC12 and aluminum alloy castings for higher-volume wheel blanks that we then machine to final size.
Brackets, spacers, covers and test fixtures that ship with the wheel program.

No adjectives. These are the figures the shop runs on.
15 years in Dongguan and Singapore, working on automotive, aerospace and industrial parts.
127 high-precision machines across 3 wholly-owned plants, so capacity is not the bottleneck.
Enough 5-axis capacity to keep multi-feature wheel work on one machine.
Repeatable tolerance on fits. We inspect against the drawing, not against a sample.
Parts that pass inspection the first time, measured before shipment.
Below 2% late delivery across shipped programs.
Hub and wheel parts machined to drawing with full inspection records.
Low-volume wheel and spacer runs from one piece to a few hundred.
Aluminum housings and rotating parts that need concentric fits.
Aluminum plates, chassis and heat paths machined and finished in-house.
Yes. Send a drawing with the bore, bolt circle, offset and spoke dimensions, or send a physical sample and we reverse-engineer the geometry. We return a DFM note with the quote so you can see which features drive cycle time.
If you only have a photo, we can still start, but the quote will be marked as provisional until we have a drawing or a part in hand.
6061-T6 covers most street and light track wheels. It machines clean, anodizes evenly and holds the hub bore over temperature cycles.
Choose 7075 when the spoke root sees repeated high load and you want extra fatigue margin. It cuts slower and does not weld well, so avoid it if the design needs a welded joint. ADC12 applies when you start from a casting we finish to size.
Both are cut in one 5-axis setup with the part clamped on the mounting face. The table indexes the part for the spoke windows without releasing the clamp.
We measure bore diameter and face runout before unclamping, so a drifting part is caught on the machine, not after shipment.
Anodizing in clear, color, hardcoat or conductive; electroless nickel, zinc, silver and gold plating; powder coating and black oxide; bead blasting, tumbling, brushing and polishing.
Laser marking and engraving are available from 1.5 mm character height. Fine machined faces on bead seats typically run Ra 0.2–0.8 μm.
There is no minimum. We run one prototype or a 10,000+ part program on the same equipment and the same inspection plan.
Prototype wheels get the same final inspection as production parts, which is how problems surface before tooling or fixtures are committed.
Quotation and free DFM analysis come back within 12 hours. Production can start within 24 hours of release, and parts typically ship in 3–5 days.
Historical late-delivery probability is below 2%. If a feature needs a custom fixture, we say so in the quote rather than after the first article.
Uploads are secure and confidential. We sign an NDA on request before you send drawings or a sample.
If the wheel design is yours, we do not use it for any other customer and we do not publish part photos without written permission.
Yes. Incoming material is checked against the certificate, dimensions are monitored in process, and 100% final inspection happens before packing.
Inspection reports are available on request, including bore diameter, runout and surface finish readings.
Upload the file and we return a quote with DFM notes within 12 hours. One part or ten thousand, same process.
