Your drawing defines the part. We machine it exactly to that drawing. Every collet chuck component—body, nut, or disassembled set—is verified before shipment. Taper angles, thread pitch, and concentricity are checked on CMM equipment. No guesswork.
This is custom CNC collet chuck work, made in China, with 20 years of shop-floor experience behind it.
| Parameter | Value |
|---|---|
| Materials | 20CrMnTi, 40Cr, 42CrMo, 304/316 stainless steel, 6061-T6 aluminum |
| Hardening | Carburized 0.8–1.2 mm depth, HRC 58–62 (steel parts) |
| Machining process | 5-axis CNC milling, CNC turning, grinding, wire EDM for internal profiles |
| Key tolerances | Taper angle ±0.005°, runout ≤0.005 mm, thread pitch class 6H/6g |
| Surface finish | Ra 0.4 µm on taper seat, Ra 0.8 µm on other functional faces |
| Inspection | 100% dimensional check, CMM report per batch |
| Batch size | 1–10,000 pieces, no MOQ |
| Lead time | 10 days for prototypes, 15 days for production runs |
| Marking | Laser engraving (material, heat code, batch number) |
We use grinding after heat treatment for taper seats. That is non-negotiable for a collet chuck. Milled-only surfaces will not hold the required concentricity.
1. Batch-traceable quality. Every batch gets a unique code. Heat treatment records, material certificates, and inspection data link to that code. If a problem appears in your assembly line, we trace it to the exact heat lot and machine operator. No ambiguity.
2. Inspection report per batch. You receive a full dimensional report with every shipment. Taper angle, runout, thread fit, hardness—all measured and documented. Our QC team uses a Zeiss CMM and a Mitutoyo profilometer. Reports are PDF, sent with the packing list.
3. One factory for CNC + stamping + spring + heatsink. Your collet chuck is not an island. It sits in a spindle, often with a drawbar spring, a stamped release ring, or a heatsink on the motor housing. We make all of those parts under one roof. You get one supplier, one quality system, one shipping point. Fewer audits, fewer delays.
We have supplied collet chuck bodies for 5-axis machining centers used in turbine blade production. We have also made small batches of collet nuts for a Swiss-type lathe shop in Ohio. Same tolerance, same process.

Q: Is there really no MOQ? A: Yes, no MOQ. We machine one prototype for your fit test. Production pricing starts at 10 pieces. Tooling costs are quoted separately only if you need a special form tool.
Q: How do you guarantee tolerance and quality? A: We inspect 100% of critical dimensions on every part. Taper angle is measured with a sine bar and indicator, not a go/no-go gauge. Runout is checked on a precision arbor. A CMM report is included per batch.
Q: What is your lead time for custom CNC collet chuck parts? A: 10–15 working days after drawing approval. For urgent orders, we can split the batch—ship the first 20% in 5 days, the rest in 10 days. We do not sacrifice inspection speed for delivery.
Q: Can you provide material certificates? A: Yes. Mill test certificates for raw material, heat treatment curves, and hardness reports are available. We keep records for 10 years. If your customer requires a specific standard (ASTM, DIN, JIS), we source to that spec.
Send us your PDF or STEP file. We review the taper, thread, and material callouts. You get a firm quote in 12 hours—not a "budget estimate." We confirm tolerances, lead time, and unit price. No surprises.
