Your drawing defines the part. We machine it to spec and verify it before shipment. No guesswork, no tolerance gambling.
This is a 700 Type round bore spring collet chuck for auto lathes. It is built for high-speed, high-repeatability gripping. We make it from your print, in the exact material and hardness you specify.
1. Batch-traceable quality. Every lot gets a unique batch number. We record material heat number, heat treatment curve, and final inspection data. If a problem appears in your line, we trace it back to the exact batch in minutes.
2. Inspection report per batch. You get a full dimensional report with every shipment. Not a generic certificate – actual measured values for bore diameter, concentricity, hardness, and surface finish. Our QC team uses CMM, optical comparators, and Rockwell hardness testers.
3. One factory for CNC + stamping + spring + heat sink. Your collet chuck is not an isolated part. Many buyers also need springs, stampings, or heat sinks for the same assembly. We run all four lines under one roof. You send one drawing package, get one quote, one quality standard, one shipping schedule.
Where these parts are used
The 700 Type round bore spring collet chuck is a workhorse in precision manufacturing. Common applications:
Swiss-type lathe workholding – gripping bar stock from Ø 3 mm to Ø 40 mm for medical screws, dental implants, and watch parts.
CNC turning centers – secondary operations on pre-machined blanks where concentricity below 0.01 mm is mandatory.
Automotive fuel injector components – high-volume production where collet wear directly affects scrap rate.
Electronics connector pins – small diameter, high-speed machining with minimal runout.
Aerospace fasteners – where material traceability and hardness consistency are audited.
These chucks run at 6,000–10,000 RPM. They grip and release millions of cycles. The spring steel temper and slot geometry are what keep them accurate over that life. We control both.
Q: What is your MOQ?
A: No MOQ. We make one prototype for your validation, then scale to your production volume. Tooling is included in the piece price for small batches.
Q: How do you guarantee tolerance and quality?
A: We inspect 100% of critical dimensions on every piece. For batches over 500 pcs, we use SPC sampling on top of full inspection. You receive the measured report, not a promise.
Q: What is the lead time for a custom CNC collet chuck?
A: 15 working days for a sample (1–5 pcs). 20 working days for production batches. If you need faster, we can split the order and ship partial lots.
Q: Can you provide material certificates and heat treatment reports?
A: Yes. We supply mill certificates for raw material and a heat treatment curve with hardness values for every batch. Third-party testing (SGS, BV) is available at your cost.
