Your custom CNC collet chuck is machined to your exact drawing, not a stock approximation. We verify every critical dimension before shipment. No surprises.
At a glance: ±0.005 mm tolerance on OD/ID, 15-day standard lead time, no MOQ, full material traceability.
We run a dedicated CNC turning line for collet chucks and hydraulic chucks. All parts are machined in-house, not outsourced.
| Parameter | Value |
|---|---|
| Material | 20CrMnTi, 40Cr, 42CrMo, 65Mn, or your specified alloy |
| Hardness | HRC 58–62 (carburized), HRC 40–45 (quenched & tempered) |
| Machining tolerance | ±0.005 mm on bore, ±0.01 mm on concentricity |
| Surface finish | Ra 0.4 µm on sealing faces, Ra 0.8 µm on taper |
| Process | CNC turning, internal grinding, wire EDM for slots |
| Inspection | 100% dimension check, CMM report per batch |
| Batch size | 1 piece to 10,000 pieces |
| Lead time | 15 days for prototypes, 25 days for production |
| Coating | Black oxide, phosphate, or hard chrome (optional) |
We hold 0.005 mm TIR between the collet taper and the pull-back seat. That is not a marketing number. It is a repeatable process capability from our Okuma and Mazak turning centers.
1. Batch-traceable quality. Every heat number, every batch, every operator stamp is logged. If you need to trace a part back to its raw material lot, we can do it in minutes. No guessing.
2. Inspection report per batch. You get a CMM report, hardness certificate, and surface roughness readings with every shipment. Not a generic compliance sheet. Real numbers from real measurements.
3. One factory for CNC + stamping + springs + heatsinks. Your chuck assembly may need a spring collet, a stamped retainer, or a heatsink for the hydraulic actuator. We make all of them under one roof. Fewer vendors, fewer tolerance stack-ups, faster root-cause analysis.
Custom CNC collet chucks from our shop run in:
In every case, the buyer needs a chuck that holds concentricity under high spindle speeds and repeated clamping cycles. That is what we build.
Looking for a different part? We also machine Precision CNC Swiss Lathe Guide Bushing Tungsten Carbide Custom Made in China in the same Dongguan factory.
Q: Do you have a MOQ? A: No. We machine one piece for prototype validation. Production pricing kicks in at 50 pieces, but you can order 5 pieces at a fair unit price.
Q: What tolerance can you hold on a collet chuck bore? A: ±0.005 mm on the bore diameter, ±0.01 mm on concentricity to the taper. For hydraulic chucks, we also verify the seal groove depth to ±0.02 mm.
Q: What is your lead time for a custom chuck? A: 15 days for a standard material prototype. 25 days for production runs with heat treatment. Faster if you supply the raw material or accept air freight.
Q: Can you provide material certificates? A: Yes. We issue EN 10204 3.1 mill certificates for all alloy steels. Heat treatment reports include hardness curves and case depth data.
