Machining process
CNC turning, internal grinding, wire EDM for slots
Heat treatment
Carburizing or induction hardening, then tempering
We run the 60 type collet on our own CNC lathes and grinders. The bore is ground after heat treatment to hold the ±0.005 mm tolerance. Slots are cut by wire EDM for clean edges and consistent spring action. Each chuck is tested with a master gauge before it leaves the floor.
Three reasons buyers send us their drawings
1. Batch-traceable quality.
Every batch gets a unique heat number and lot code. You can trace the material certificate, heat treatment record, and inspection data back to the exact shift that made your parts. No mixing, no guesswork.
2. Inspection report per batch.
You receive a dimensional report for every batch, not just a sample. We measure bore diameter, taper angle, concentricity, and hardness on each piece or per AQL sampling plan. The report is signed by our QC engineer and sent with the shipment.
3. One factory for CNC + stamping + spring + heatsink.
Your collet chuck is one component. Maybe you also need a spring, a stamped retainer, or a heatsink for the spindle motor. We make all of them under one roof. One purchase order, one quality system, one shipping date. You save time and freight cost.
Where these parts are used
The 60 type round bore collet chuck is a workhorse in automatic lathes and Swiss-type machines. Typical applications:
High-volume turning of small shafts – pins, rollers, and valve stems, where quick clamping cycles matter
Bar feeding operations – holding round bar stock from Ø3 mm to Ø60 mm for continuous machining
Secondary operations – drilling, reaming, or thread cutting on parts already turned, where concentricity must stay under 0.01 mm
Medical device parts – bone screws and surgical pins, where surface finish and repeatability are critical
Electrical connectors – brass or copper contacts machined at high spindle speeds, requiring a chuck that grips without marking the surface
The round bore design gives you full contact around the workpiece. That means less deformation on thin-walled parts and better grip on hardened materials. It is the right choice when you need a reliable, repeatable clamping solution for your auto lathe.
Questions buyers ask before ordering
Q: Is there a minimum order quantity?
A: No MOQ. We accept one-piece prototype orders and scale up to full production. The unit price drops with quantity, but you never pay a penalty for starting small.
Q: What tolerance can you hold on the bore and taper?
A: We hold ±0.005 mm on the bore diameter and ±0.01 mm on the taper angle. Concentricity between the bore and the outer taper is kept under 0.008 mm TIR. We verify every chuck with a master gauge before shipment.
Q: What is your typical lead time?
A: Prototypes ship in 15 working days. Production runs of 100–1000 pcs take 25 working days. For urgent orders, we can expedite to 10 days at a 10% surcharge. We confirm the exact date when you send your drawing.
Q: Do you provide material certificates and heat treatment reports?
A: Yes. Every batch includes a material certificate (EN 10204 3.1), a heat treatment report with hardness values, and a dimensional inspection report. These documents are included free of charge with every shipment.
