Three reasons buyers send us their drawings
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.
Where these parts are used
The 46 type quenched dark collet chuck is standard for Swiss-type and sliding-headstock auto lathes. Common applications:
Medical device machining – holding small-diameter stainless pins and titanium screws for implants. The dark oxide layer reduces galling on repeated clamping cycles.
Watch and jewelry manufacturing – precise gripping of brass, bronze, and precious metal blanks down to 0.5 mm diameter.
Electronics connectors – machining contact pins and sockets from copper alloys, where burr-free clamping is critical.
Automotive fuel injectors – high-volume production of nozzle bodies, requiring consistent clamping force across thousands of cycles.
Aerospace fasteners – small titanium bolts and rivets, where hardness and wear resistance matter for long runs.
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.
