This is a custom CNC collet chuck for auto lathe 46 type spindles. Long nose, extended reach, built to your exact geometry. We hold tolerances to 0.005 mm on critical diameters. Every unit is verified before shipment. No exceptions.
Tolerance: ±0.005 mm on OD/ID, ±0.01 mm on length
Lead time: 15–20 working days for standard steel grades
No MOQ – order one piece or one thousand
Material certs included with every batch
We are a precision manufacturing factory in Dongguan, China. 20 years of CNC machining, stamping, springs, and heat sinks under one roof. You send the drawing. We send back a part that fits your spindle and holds your workpiece.
Laser engraving per your spec (part no., date code, logo)
We use CNC lathes with live tooling for the blank, then grind the taper and bore on dedicated collet grinders. The long nose section is stress-relieved after roughing to prevent distortion. Final lapping gives the sealing surface a mirror finish.
Three reasons buyers send us their drawings
1. Batch-traceable quality.
Every heat of steel has a unique lot number. We record it in your job file. If a part fails in the field, we trace it back to the exact bar stock, machine, and operator. No guesswork.
2. Inspection report per batch.
You get a full dimensional report with each shipment. Not a generic certificate – a real table of measured values for every critical feature. Taper angle, concentricity, hardness, surface finish. We sign it. You can audit it.
3. One factory for CNC + stamping + springs + heat sinks.
Your collet chuck might need a spring collet insert or a stamped retainer ring. We make those in the same building. One purchase order, one quality system, one shipping date. Less coordination, fewer delays.
Where these parts are used
Auto lathe 46 type collets are workholding components. They grip bar stock or pre-machined blanks during turning, drilling, and threading. The long nose extension reaches into deep bores or past fixed guides.
Swiss-type and automatic lathe spindles for medical screw blanks
Watch pinion and gear blank machining – small diameters, high concentricity
Automotive fuel injector nozzle bodies – extended nose clears the fixture
Electrical connector pins – long, slender parts need support close to the cut
Aerospace fastener blanks – repeatable grip force over thousands of cycles
The 46 type refers to the spindle nose taper and thread size. It fits common Japanese and Korean auto lathes (Citizen, Star, Tsugami, Hanwha). If your spindle is different, we make that too. Just send the drawing.
Q: What is your MOQ?
A: No MOQ. We machine one prototype for your fit test, then scale up. Tooling cost is amortized into the unit price for production runs.
Q: How do you guarantee tolerance and quality?
A: We grind the taper and bore on dedicated machines. Each part is measured on a CMM and a taper gauge. The inspection report is included. If a part is out of spec, we replace it at no cost.
Q: What is your lead time for a custom collet chuck?
A: 15 working days for a prototype after drawing approval. Production runs of 100+ pieces take 20 working days. Rush orders are possible for an extra fee – we have a dedicated quick-turn cell.
Q: Do you provide material certificates?
A: Yes. Every batch includes a mill certificate for the raw material and a hardness test report. If you need third-party testing (SGS, BV), we arrange it at cost.
