Your drawing defines the part. Our machines execute it. We make custom CNC collet chucks from 20 mm to 200 mm OD, with bore sizes from 1 mm to 50 mm. Every unit is verified before shipment—not sampled, not spot-checked. We measure critical dimensions on a CMM and record the data. If it does not match your print, it does not ship.
We are a precision manufacturing factory in Dongguan, China, with 20 years of CNC machining experience. You send the drawing. We return a part that fits your spindle and holds your workpiece.
| Parameter | Value |
|---|---|
| Material | 20CrMnTi, 42CrMo, 65Mn, SUS440C, SUS304, AISI 4140 |
| Hardness | 58–62 HRC (case-hardened), 40–45 HRC (through-hardened) |
| OD range | 20 mm – 200 mm |
| Bore range | 1 mm – 50 mm |
| Taper angle | 16°, 20°, 30°, or per drawing (JIS, DIN, ER, and custom) |
| Tolerance | ±0.005 mm on bore, taper, and concentricity |
| Surface finish | Ra 0.4 µm on bore, Ra 0.8 µm on OD |
| Process | CNC turning, internal grinding, wire EDM for slots, heat treatment |
| Inspection | 100% CMM check, hardness test, concentricity gauge |
| Batch size | 1 piece to 100,000 pieces |
| Lead time | Prototype 10–15 days, production 20–25 days |
| Certifications | ISO 9001:2015, material mill certs, heat treatment reports |
We grind the bore after heat treatment. This holds the taper angle within 0.002 mm over the full length. Slots are wire-cut, not milled, to avoid burrs and maintain edge sharpness. Each collet is serialized for traceability.
1. Batch-traceable quality Every collet gets a serial number. We link it to the material heat number, heat treatment batch, and inspection records. If a part fails in your machine six months from now, we can trace it to the exact steel pour and quench cycle. No guesswork. No blame-shifting.
2. Inspection report per batch You get a full dimensional report with every order. This includes bore diameter, taper angle, concentricity, hardness, and surface roughness. We also send photos of the CMM screen and the actual part. You do not need to re-measure our parts. You can, but you will not find a discrepancy.
3. One factory for CNC + stamping + springs + heat sinks We run four production lines under one roof: CNC machining, metal stamping, spring winding, and heat sink fabrication. If your collet chuck assembly needs a spring-loaded pusher, a stamped retainer, or a heat-treated housing, we make it here. You deal with one engineer, one invoice, one shipping point. This cuts your supplier management time by at least 30%.
Custom CNC collet chucks from our factory run in Swiss-type lathes, CNC turning centers, and automatic bar feeders. You will find them in:

Q: What is your MOQ? A: No MOQ. We make one prototype for you to test, or we run 100,000 pieces. The price per piece drops with volume, but the quality standard stays identical. We do not change processes for small orders.
Q: How do you guarantee tolerance and quality? A: We measure 100% of critical dimensions on a CMM. The bore and taper are ground, not turned, to achieve ±0.005 mm. We send you the inspection report with the shipment. If a part is out of spec, we replace it at no cost, including shipping.
Q: What is your lead time for a custom CNC collet chuck? A: Prototypes ship in 10–15 working days after drawing approval. Production runs of 1,000+ pieces ship in 20–25 days. We can expedite to 7 days for an urgent prototype, subject to material availability.
Q: Do you provide material certificates and heat treatment reports? A: Yes. Every batch includes a mill certificate for the raw material and a heat treatment report showing hardness and case depth. We also provide a RoHS and REACH compliance statement if your application requires it.
Stop comparing quotes from middlemen. Work directly with the factory. Send us your drawing, and we will return a firm quote within 12 hours. Include your material, tolerance, and quantity. We will tell you if your design can be made faster or cheaper without compromising quality.
