We are a precision manufacturing factory in Dongguan, China, with 20 years on CNC turning, milling, and grinding lines. Your collet is not a side job. It is our core process.

All collets are stress-relieved after rough machining, then ground in one setup. This keeps bore and taper concentric. We do not skip tempering.
1. Batch-traceable quality Each batch gets a unique heat number and work order. Raw material certs are archived for 5 years. If you need to trace a part back to its steel melt, we can do that in minutes.
2. Inspection report per batch You receive a dimensional report with every shipment. It lists bore diameter, taper angle, concentricity, and hardness. No extra charge. No surprises.
3. One factory for CNC + stamping + spring + heatsink Your collet is only one part of the assembly. We also run CNC machining, metal stamping, springs, and heat sink lines under one roof. Send us the full BOM. We quote the whole package, not just the collet. That saves you freight, handling, and supplier management time.
Auto Lathe 46 Type collets are for Swiss-type and sliding headstock lathes that feed round bar stock. Typical applications:
In each case, the collet grips the bar with even pressure. A poor collet means chatter, oval parts, or bar slippage. Our ground bore and taper eliminate that.

Q: What is your MOQ? A: No MOQ. We make one piece for prototype validation, then scale to your volume. Tooling is standard for 46 Type, so setup cost is low.
Q: How do you guarantee tolerance and quality? A: We grind the bore and taper in one clamping. Then every part is checked on a CMM with a 0.001 mm resolution. The inspection report is included in the shipment. If any dimension is out, we rework or replace at no cost.
Q: What is the lead time for a custom collet? A: For 1–50 pieces, 7 working days. For 51–500 pieces, 12 working days. For larger orders, we confirm a schedule within 24 hours of drawing review.
Q: Can you provide material certificates? A: Yes. We supply mill test certificates for A2, D2, 4140, or any specified grade. Certificates are traceable to the batch heat number.
