Your drawing becomes a finished quenched dark collet chuck, verified before shipment. We run every custom CNC collet chuck through a 100% dimensional check with a CMM and hardness tester. No guesswork, no surprises at your incoming inspection.

1. Batch-traceable quality. Each heat number and batch gets a unique code. You can trace material, quenching curve, and final inspection data back to the exact machine and operator. No mixed batches, no hidden substitutions.
2. Inspection report per batch. You receive a full report: hardness values, bore and taper measurements, concentricity, and surface finish. We photograph the actual parts and attach the CMM printout. Your QC team can skip incoming inspection if they trust the report.
3. One factory for CNC + stamping + springs + heat sinks. Your collet chuck doesn’t live in isolation. If your assembly also needs a stamped retainer, a compression spring, or a heat sink for the spindle motor, we make them under the same roof. One purchase order, one quality system, one shipping date.
The 46 type quenched dark collet chuck is standard for Swiss-type and sliding-headstock auto lathes. Common applications:
The quenched dark finish is not cosmetic. It adds a thin magnetite layer that resists rust and reduces friction between the collet and the spindle. You get longer tool life and fewer stuck parts in humid shop environments.

Q: What is your MOQ? A: No MOQ. We make one prototype for your trial, then scale to your production volume. Tooling cost is amortized into the unit price for larger batches.
Q: How do you guarantee tolerance and quality? A: We use CNC grinding and wire EDM for the slots. Every piece is measured with a CMM and a calibrated taper gauge. Hardness is verified on a Rockwell tester. We send the inspection report with every shipment.
Q: What is the lead time for a custom collet chuck? A: Prototype in 3–5 working days after drawing approval. Standard production batches ship in 7–12 working days. For urgent orders, we can split the batch and airfreight the first 10 pieces.
Q: Can you provide material certificates? A: Yes. We supply mill certificates for the raw material, heat treatment reports with the quenching curve, and a certificate of conformity for the finished parts. All documents are in English.
Send us your 2D drawing or 3D model. We will check the tolerances, suggest a material if you are unsure, and give you a firm quote within 12 hours. No obligation, no design fee for standard collet chuck configurations.
