Your drawing becomes a finished collet set. We machine it, verify it, and ship it. Every piece is checked against your print before packing. No surprises at your incoming inspection.
Tolerance: ±0.005 mm on critical diameters
Lead time: 7–12 working days for standard materials
No MOQ — order one piece or one thousand
Material certs included with every batch
This is a custom CNC collet chuck, not an off-the-shelf item. You send the drawing. We handle the rest.
±0.005 mm on bore, ±0.01 mm on OD, ±0.02 mm on length
Surface finish
Ra 0.4 µm on gripping surfaces, Ra 0.8 µm elsewhere
Thread accuracy
Class 2A/2B, verified with thread gauges
Slit width
0.3–1.5 mm, EDM wire-cut, burr-free
Batch size
1–50,000 pieces, no MOQ
Inspection
100% critical dimensions, CMM report per batch
Lead time
7 days for prototypes, 12 days for production runs
We run these on Citizen and Star Swiss-type lathes, plus Tsugami and Hanwha CNC machines. Grinding is done on Studer and Jung internal/external grinders. This combination gives you roundness within 0.003 mm and concentricity within 0.005 mm TIR.
Three reasons buyers send us their drawings
1. Batch-traceable quality
Each collet gets a unique heat number. We record material lot, machine operator, and inspection results. If a problem shows up in your line, we trace it to the exact batch and correct it. No guesswork.
2. Inspection report per batch
You get a full dimensional report with every shipment. Critical diameters, taper angles, slit widths, hardness values — all documented. Our QC team uses CMM, optical comparators, and hardness testers. Reports are signed and archived for three years.
3. One factory for CNC + stamping + springs + heatsinks
Your collet chuck might need a spring, a stamped retainer, or a heatsink for a thermal application. We make all of them under one roof. Fewer suppliers, fewer handoffs, fewer tolerance stack-ups. One purchase order covers the whole assembly.
Where these parts are used
Our custom CNC collet chucks run in real production environments. Common applications include:
Swiss-type lathe workholding for medical bone screws and dental implants
High-speed machining centers for automotive fuel injector bodies
Pneumatic collet chucks on CNC auto lathes (36 and 46 type spindles)
Indexing fixtures for aerospace fasteners and hydraulic fittings
Replacement collets for worn or damaged OEM chucks in job shops
The 36 and 46 type refers to the spindle nose size. We match your machine's taper and pull-back geometry exactly. If you are not sure about the spec, send us your old collet or the chuck body drawing. We reverse-engineer it and quote within 12 hours.
Q: What is your MOQ?
A: No MOQ. We make one piece for prototype validation or 50,000 pieces for production. Pricing is tiered, but the first piece gets the same attention as the last.
Q: How do you guarantee tolerance and quality?
A: We use in-process gauging and post-process CMM inspection. Critical dimensions are checked 100%. A full inspection report is included with each batch. If anything is out of spec, we replace it at no cost.
Q: What is your lead time?
A: Standard lead time is 7–12 working days after drawing approval and material confirmation. For rush orders, we can ship in 5 days for an expedite fee. We do not quote lead times we cannot meet.
Q: Do you provide material certificates?
A: Yes. Every batch comes with mill certificates for the raw material, heat treatment reports, and hardness verification. If you need third-party testing, we coordinate it at cost.
Send your drawing
Precision manufacturing starts with a conversation. Send us your drawing, your old part, or even a sketch. We will review the geometry, suggest improvements if needed, and give you a firm quote within 12 hours.
