Your drawing defines the part. We machine it.
Every 5C collet chuck we ship is made to your exact print. We verify critical dimensions before the batch leaves Dongguan. No surprises at your incoming inspection.
We are a precision manufacturing factory with 20 years of CNC machining, stamping, springs, and heat sink lines under one roof. Your custom CNC collet chuck is made by engineers, not just operators.
| Parameter | Value |

| Batch size | 1–5000 pieces, no MOQ |
| Lead time | 7 days for prototypes, 12 days for production runs |
| Packaging | Individual foam wrap, export carton, or custom tray |
We grind the 5C taper on a dedicated cylindrical grinder. Bore concentricity is held to 0.005 mm TIR. Every chuck is deburred and passivated to prevent rust during transit.
1. Batch-traceable quality. Each heat lot gets a unique code. We record material cert, machining parameters, and inspection results against that code. If a problem appears in your line, we trace it back to the exact batch in minutes. No guesswork.
2. Inspection report per batch. You get a dimensional report with every shipment. It lists all critical features: taper angle, bore diameter, thread pitch, hardness, and surface finish. Our QC team uses a CMM and hardness tester calibrated monthly. If a dimension is out, we catch it before packing, not after you receive it.
3. One factory for CNC + stamping + springs + heat sinks. Your custom CNC collet chuck is often part of a larger assembly. We also make the springs, stamped retainers, and heat sinks that go around it. One purchase order, one quality system, one shipping point. Fewer suppliers, fewer delays.
5C collet chucks are not just for lathes. Our customers use them in:
In every case, the chuck must grip without marring the part and release without sticking. Our hardened and ground bore does exactly that.
Looking for a different part? We also machine Custom CNC Collet Chuck Machined to Drawing | BQUQ China Factory in the same Dongguan factory.
Q: What is your MOQ? A: No MOQ. We make one prototype or a thousand production pieces. Tooling cost is amortized into the unit price for repeat orders.
Q: How do you guarantee tolerance and quality? A: We grind the taper and bore after heat treatment. Every batch gets a CMM inspection report. If a part is out of spec, we rework or scrap it before shipment, at our cost.
Q: What is your lead time for a custom CNC collet chuck? A: 7 working days for prototypes, 12 working days for production runs. For urgent orders, we can split the batch and ship the first 20 pieces in 3 days.
Q: Can you provide material certificates? A: Yes. We supply mill certificates for every heat, plus our own hardness and dimensional reports. All documents are in English and PDF format.
