Your drawing defines the part. We machine it to that drawing, verify every critical dimension, and ship only after passing inspection.
This is a 52-type collet chuck for automatic lathes. It is quenched and darkened for wear resistance and corrosion control. We make it to your exact bore profile, thread pitch, and slot geometry.
We are a precision manufacturing factory in Dongguan, China, with 20 years of experience. You send the drawing. We return a firm quote and a part that fits your spindle.

1. Batch-traceable quality. Every collet chuck gets a unique batch number. We record heat treatment curves, grinding wheel specs, and final inspection data. If a problem appears in your production, we trace it back to the exact heat lot and machine operator.
2. Inspection report per batch. You receive a dimensional report with actual measured values, not just a pass/fail stamp. We measure bore diameter, concentricity, slot width, and hardness. The report is signed by our QC engineer and sent with the shipment.
3. One factory for CNC + stamping + springs + heat sinks. Your collet chuck is not the only part you need. We also run CNC machining, metal stamping, spring coiling, and heat sink fabrication lines. Send us a full assembly drawing. We coordinate all processes under one roof, one quality system, one shipping date.

Q: Is there a minimum order quantity? A: No. We accept single-piece prototypes and full production runs. The price per piece drops with quantity, but we do not force you to over-order.
Q: What tolerance and quality can you guarantee? A: Standard tolerance is ±0.005 mm on bore and slot widths, with concentricity ≤0.005 mm TIR. We provide a CMM inspection report for every batch. If we miss a dimension, we remake the part at no cost.
Q: What is the lead time for a custom CNC collet chuck? A: For standard 52-type with your bore and thread spec, 10–15 working days. For fully custom profiles with special slots or coatings, allow 20 working days. We can expedite to 7 days for urgent orders, subject to material availability.
Q: Do you provide material certificates and heat treatment reports? A: Yes. Each batch ships with a mill certificate for the raw material, a hardness test report, and a heat treatment curve. We can also provide third-party testing (SGS, BV) at your request.
We respond with a firm quote within 12 hours, including unit price, tooling cost (if any), and delivery date.
