Your differential gear drawing is our starting point. We machine it to print, verify it on a CMM, and ship it with a full inspection report. No guesswork, no "close enough."
We are BQUQ, a precision manufacturing factory in Dongguan, China. We have run CNC lines for 20 years. We make gear parts for drivetrains, axles, and transfer cases. Every batch is traceable to raw material heat numbers and machine operator.

| Certifications | ISO 9001:2015, material certificates, heat treatment reports |
We handle the full gear manufacturing chain in-house. Cutting, heat treatment, grinding, and final inspection happen under one roof. That means shorter lead times and fewer quality gaps.
1. Batch-traceable quality. Every part gets a unique batch number. We record raw material heat, machine used, operator, and inspection results. If a problem appears in your assembly line, we trace it to the exact operation in minutes. You get a PDF report with each shipment.
2. Inspection report per batch. We do not ship parts without measuring them. Each batch includes a dimensional report, material cert, and hardness test results. For critical dimensions, we provide CMM data points. You can verify our work before parts leave our dock.
3. One factory for CNC + stamping + springs + heat sinks. Your differential assembly likely needs more than just gear parts. We also run metal stamping, spring manufacturing, and heat sink lines. You send us one drawing package, we coordinate all processes, and you receive one consolidated shipment. Fewer vendors, fewer delays, one accountable partner.
CNC machined differential gear parts go into systems that transfer torque and manage speed differences.
These parts see high cyclic loads, shock torque, and continuous sliding contact. That is why we control material hardness, tooth profile, and surface finish to tight limits.

Q: What is your MOQ? A: No MOQ. We machine one prototype for validation or run 100,000 pieces for production. Tooling and setup costs are quoted per order, so small batches stay economical.
Q: How do you guarantee tolerance and quality? A: We use CMM and gear testers on every batch. Critical dimensions are checked at 100%. We also provide a full inspection report with the shipment. If a part is out of spec, we replace it at no cost.
Q: What is your lead time for custom CNC machining? A: Prototypes ship in 7–10 days after drawing approval. Production runs of 500+ pieces ship in 20–25 days. Heat treatment adds 3–5 days, depending on the case depth required.
Q: Can you provide material certificates? A: Yes. Every order includes a mill certificate for the raw material, heat treatment records, and hardness test results. We keep records for 10 years.
We quote within 12 hours. Send your PDF or STEP file, specify material and quantity, and we return a firm price with lead time.
