Your conveyor system is only as reliable as its rollers. We machine them to your drawing, not to a catalog standard. Every part is verified before shipment. If the print says ±0.01 mm, you get ±0.01 mm. If it says Ra 0.8, you get Ra 0.8.
We are a precision manufacturing factory in Dongguan, China, with 20 years on CNC lines. You send the drawing. We send back parts that drop into your assembly without rework.
| Parameter | Value |
|---|---|
| Materials | 6061/7075 aluminum, 1045/4140 steel, 303/304/316 stainless, C360 brass, POM-C, PA6 |
| CNC machines | 3-axis, 4-axis, 5-axis; Mazak and Fanuc controls |
| Max part size | 800 mm diameter, 2000 mm length (turning); 1000 x 800 x 500 mm (milling) |
| Tolerance | ±0.005 mm (precision), ±0.01 mm (standard), ±0.05 mm (general) |
| Surface finish | Ra 0.4 µm (ground), Ra 0.8 µm (turned/milled), Ra 1.6 µm (standard) |
| Processes | CNC turning, milling, drilling, tapping, boring, grooving, knurling |

| Batch size | 1–100,000 pieces; no MOQ |
| Inspection | CMM, micrometer, bore gauge, surface profilometer; report per batch |
| Lead time | 7 days for prototypes, 15–25 days for production (depending on qty) |
We hold tolerances on shaft diameters, bore concentricity, and face runout. For rollers, that means less vibration, longer bearing life, and consistent tracking on your line.
1. Batch-traceable quality. Every heat number, every batch, every operator. We assign a unique job number to your order. That number follows the material from the saw to the CMM. If a part fails in the field, we trace it back to the exact machine, tool, and operator shift. No guesswork.
2. Inspection report per batch. You get a dimensional report with every shipment. Critical features are measured 100%. Non-critical features are sampled per AQL 2.5. The report lists actual values, not just pass/fail. Your QC team can file it without re-measuring. That saves you hours per order.
3. One factory for CNC + stamping + springs + heat sinks. Your conveyor roller might need a CNC-machined shaft, a stamped end cap, a compression spring for tensioning, and a heat sink for a motor drive. We do all four in-house. You deal with one engineer, one shipping dock, one invoice. Fewer vendors means fewer tolerance stack-ups and fewer delays.
CNC machined conveyor rollers are not just for warehouses. They go into:
We also machine custom rollers for OEMs who need non-standard diameters, keyways, or threaded ends. If your conveyor has a special requirement, we build to that spec.

Q: What is your MOQ? A: No MOQ. We run one prototype for validation or 100,000 pieces for production. The unit price drops with quantity, but the setup cost is the same. For small batches, we combine multiple parts on one fixture to keep your cost down.
Q: How do you guarantee tolerance and quality? A: We use in-process probing on the CNC machines. After machining, we verify critical dimensions on a CMM (accuracy ±0.002 mm). Every batch gets a full inspection report. If a part is out of spec, we rework or scrap it—never ship it.
Q: What is your lead time for custom CNC machining? A: Prototypes: 7 days from drawing approval. Production: 15–25 days depending on quantity and material. For urgent orders, we can split the batch and ship the first 20% in 5 days. We quote realistic dates and hit them.
Q: Can you provide material certificates? A: Yes. We supply mill certificates for all metals, including chemical composition and mechanical properties. For aerospace or medical applications, we can provide full traceability with heat numbers and batch records.
Stop guessing if a factory can hold your tolerance. We will tell you in 12 hours—firm quote, not a range. Send your drawing in PDF, STEP, or IGES format. We will review the material, tolerances, and quantity, then get back to you with a price and lead time.
