Your drawing defines the part. We build it exactly to that spec. Every custom CNC collet chuck is machined from solid stock, heat-treated if required, and ground on critical diameters. We verify concentricity and synchronization before shipment. You get a part that fits your auto lathe spindle the first time.
| Parameter | Value |
|---|---|
| Material options | 20CrMnTi, 40Cr, 9CrSi, 65Mn, or customer-specified |
| Hardness | 58–62 HRC after carburizing or induction hardening |
| Machining process | CNC turning, internal grinding, cylindrical grinding, wire EDM for slots |
| Synchronization accuracy | ≤0.01 mm TIR between jaws |
| Bore tolerance | H7 or tighter per drawing |
| Taper angle | Standard 15° or custom per drawing |
| Surface finish | Ra 0.4 µm on gripping surface, Ra 0.8 µm elsewhere |
| Batch size | 1 to 10,000 pieces – no tooling change penalty for small runs |
| Inspection | 100% dimensional check on critical features, CMM report included |
| Certification | Material certificate (mill test report) available per batch |
We run these on our own CNC lathes and grinding machines. No outsourced steps. That keeps tolerances tight and lead times predictable.
1. Batch-traceable quality. Each heat number and batch is recorded. If you need to trace a part back to its raw material, we can do that in minutes. We keep records for five years.
2. Inspection report per batch. You get a dimensional report with every shipment. It lists bore diameter, taper angle, jaw synchronization, and hardness. No surprises at your incoming QC.
3. One factory for CNC + stamping + spring + heatsink. Your collet chuck is not the only part you need. We make springs for the chuck release mechanism, stampings for the actuator plate, and heat sinks for your spindle drive. One purchase order, one shipping address, one quality standard.
Custom CNC collet chucks are not shelf items. They go into specific machines and processes.
If you are cutting brass, aluminum, steel, or plastics, the chuck must grip without distortion. Our synchronized design does that.

Q: What is the minimum order quantity? A: No MOQ. We make one piece for prototyping or 5,000 pieces for production. The unit price drops with quantity, but the first piece is never a gamble.
Q: How do you guarantee tolerance and quality? A: We grind after heat treatment. That removes distortion. We measure every chuck on a CMM and a dedicated synchronization tester. The inspection report is included in the shipment. If a part fails your incoming inspection, we replace it at no cost.
Q: What is the typical lead time? A: 15 working days for standard materials and sizes. For urgent orders, we can expedite to 7 days if the drawing is clear and material is in stock. We will confirm the exact date when you send the drawing.
Q: Can you provide material certificates? A: Yes. We supply mill test reports for the raw material with each batch. We also provide hardness test reports and, if needed, a full chemical composition analysis.
