Your drawing defines the part. We make it exactly to that drawing—no interpretation, no shortcuts. Every custom CNC collet chuck body is machined, heat-treated, and inspected before shipment. We verify concentricity, taper angle, and pull-back dimensions on every unit.
| Parameter | Value |
|---|---|
| Materials | 20CrMnTi, 40Cr, 42CrMo, 65Mn, 9Cr18, SUS440C, SUS303, SUS304 |
| Hardening | Carburized 0.3–0.8 mm depth, HRC 58–62; or induction hardened |
| Machines | 5-axis CNC mills, CNC lathes, ID/OD grinders, wire EDM |
| Taper accuracy | AT3 or better (ISO 15488 / DIN 6499) |
| Concentricity | ≤0.005 mm TIR between taper and clamping bore |
| Surface finish | Ra 0.2–0.4 µm on taper, Ra 0.8 on body |
| Balancing | G2.5 or G1.0 per ISO 1940, if specified |
| Batch size | 1–10,000 pieces, same process control |
| Inspection | CMM, air gauge, optical comparator, hardness tester |
| Surface treatment | Black oxide, hard anodize, electroless nickel, or as-drawn |
1. Batch-traceable quality. Every heat lot gets a unique code. We record material cert, heat treatment parameters, and final gauge readings. If a problem appears in your spindle, we trace it to the exact batch and shift. No guesswork.
2. Inspection report per batch. You get a dimensional report with actual measured values—not just a pass/fail stamp. We include runout plots, taper angle deviations, and hardness readings. Your QC team can file it without re-checking.
3. One factory for CNC + stamping + spring + heatsink. Your collet chuck is not the only part you need. We also make stamped retainers, compression springs for the chuck mechanism, and aluminum heatsinks for the spindle motor. One purchase order, one logistics point, one quality standard. Fewer suppliers, fewer delays.
Custom CNC collet chucks are not limited to standard ER collets. We machine bodies for:
If your application needs a non-standard taper angle, a longer nose, or a custom flange, we machine it from solid. No off-the-shelf compromise.
Looking for a different part? We also machine Custom CNC Machined ER40 Spring Collet Chuck for End Mill Milling in the same Dongguan factory.
Q: What is your MOQ? A: No MOQ. We run one prototype for your validation, then scale to your production quantity. Tooling and setup costs are quoted separately for small batches.
Q: How do you guarantee tolerance and runout? A: We grind the taper and bore in the same setup after heat treatment. Final runout is measured on a precision air spindle with a 0.0001 mm resolution gauge. The inspection report shows the actual numbers.
Q: What is your lead time? A: Standard 7–12 working days for prototypes. Production batches of 100–500 pieces take 15–20 working days. If you need faster, we can expedite for a small surcharge—just ask.
Q: Can you provide material certificates and heat treatment reports? A: Yes. We supply mill certificates for raw material and a heat treatment report with hardness curves and case depth. All documents are traceable to your batch number.
We quote firm in 12 hours. Send your 2D or 3D file, specify material and quantity, and we will reply with unit price, tooling cost (if any), and delivery date. No hidden charges.
