All hubs are deburred and cleaned before packaging. We hold critical dimensions like the center bore and bolt circle to tighter than standard tolerances because a loose hub means vibration, noise, and premature bearing wear.
Three reasons buyers send us their drawings
1. Batch-traceable quality
Each batch gets a unique job number. We record material heat number, machine operator, tool offsets, and inspection results. If a part fails in the field, we trace it back to the exact batch and correct the process. No guesswork.
2. Inspection report per batch
You receive a CMM report with every shipment. It lists all critical dimensions, surface finish values, and material hardness. For robot hubs, we also include concentricity and runout data. You do not need to re-inspect on arrival—just spot-check and assemble.
3. One factory for CNC + stamping + springs + heat sinks
Your robot wheel assembly may need a stamped steel insert, a compression spring for the suspension, or a heat sink for the motor. We do all four in-house. No separate suppliers, no shipping delays, no tolerance mismatches between parts. One purchase order, one quality standard.
Where these parts are used
CNC machined robot wheel hubs appear in applications where standard off-the-shelf hubs fail.
AGV and AMR platforms: Custom bolt patterns for different motor shafts, lightweight 7075 aluminum for lower inertia, and hard-anodized surfaces for floor debris resistance.
Humanoid and service robots: Small-diameter hubs with integrated encoder mounting features, machined to ±0.005 mm to keep wheel alignment accurate at high speeds.
Outdoor inspection robots: Stainless steel hubs for corrosion resistance, with sealed bearing seats machined to press-fit tolerance.
Heavy-duty industrial robots: 42CrMo steel hubs with induction-hardened splines for high torque transfer. We machine the spline profile in one setup to ensure concentricity.
Medical and lab robots: PEEK hubs for sterilizable, lightweight, and chemical-resistant wheels.
In every case, the hub is the interface between the motor and the wheel. If it is off by a few microns, you feel it as wobble or hear it as noise. We machine it right the first time.
Q: What is your MOQ for CNC machined robot wheel hubs?
A: No MOQ. We machine one prototype for your fit test, then scale to 10,000 pieces. Tooling and setup costs are quoted separately for small batches, but unit price drops significantly at 100+ pieces.
Q: How do you ensure tolerance and quality?
A: We use a 3D model to program the CNC path, then inspect the first article on a CMM. Critical dimensions like bore diameter and bolt circle are measured 100% on production parts. You get the inspection report with the shipment.
Q: What is your lead time for custom CNC machining?
A: Prototypes in 7 days, production in 15–20 days after drawing approval. For urgent orders, we can rush a prototype in 48 hours at a 30% surcharge. We confirm the exact lead time before you pay.
Q: Can you provide material certificates?
A: Yes. We provide EN 10204 3.1 material certificates for metal parts and FDA-grade certificates for PEEK and POM. All materials are purchased from certified mills, and we keep the certificates for 10 years.
