## Opening Your CNC collet chuck starts as a drawing. We machine it to that drawing, then verify it before shipment. Every thread, every taper, every concentricity check is documented.
This is a custom CNC collet chuck body with a spindle mount, built for your machine, not a generic shelf part. We hold tolerances down to ±0.005 mm on critical diameters. Lead time is 15–20 days for most batches. No MOQ—send one piece or one thousand.
## Specifications We run a 20-year-old factory in Dongguan with 5-axis CNC mills and CNC lathes. For collet chucks, we use turning, milling, and grinding in sequence. Hard turning after heat treatment keeps the taper geometry stable.
| Parameter | Value |
|---|---|
| Materials | 4140 alloy steel (pre-hardened), 17-4PH stainless, 6061-T6 aluminum, or your spec |
| Process | CNC turning, 5-axis milling, cylindrical grinding, thread milling |
| Tolerance | ±0.005 mm on bore and taper; ±0.01 mm on general dimensions |
| Surface finish | Ra 0.4 µm on taper, Ra 1.6 µm on mounting faces |
| Threads | Class 2A/2B or better, verified with thread gauges |
| Heat treatment | Optional: 28–32 HRC for 4140, or through-hardened to 40–45 HRC |
| Batch size | 1 to 10,000+ pieces |
| Inspection | 100% critical dimension check, CMM report per batch |
| Lead time | 15 days for prototypes, 20 days for production runs |
We grind the taper after heat treatment. This removes distortion and gives you a seat that holds the collet without runout. We also balance the chuck body if your spindle speed exceeds 8,000 RPM.
## Three reasons buyers send us their drawings 1. Batch-traceable quality. Each batch gets a unique job number. We track material heat numbers, tool wear, and operator initials. If a problem shows up in your assembly line, we trace it back to the exact shift and machine.
2. Inspection report per batch. You get a CMM report with actual measured values, not just a pass/fail stamp. We measure taper angle, concentricity, and thread pitch. The report ships with the parts.
3. One factory for CNC + stamping + springs + heatsinks. Your collet chuck might need a spring collet, a stamped retainer, or a heatsink for a motor spindle. We make all of them under one roof. Fewer suppliers, shorter logistics, one quality standard.
## Where these parts are used Custom CNC collet chucks show up in high-precision workholding setups. Common applications:
If your spindle has a specific flange or thread pattern, we match it. We have made chucks for BT30, BT40, CAT40, HSK63A, and proprietary mounts.
## Questions buyers ask before ordering Q: What is your MOQ? A: No MOQ. We machine a single prototype for testing. Production pricing kicks in at 50 pieces, but you are never forced to order more than you need.
Q: How do you guarantee tolerance and quality? A: We use in-process probing on the CNC machine, then verify with a CMM after grinding. Critical dimensions are measured at 20°C in a temperature-controlled room. The inspection report is included with your shipment.
Q: What is the lead time? A: 15 days for a prototype batch (1–5 pieces). 20 days for production runs. If you need faster, we can split the batch and air-freight the first pieces.
Q: Do you provide material certificates? A: Yes. We provide mill certificates for the raw material, heat treatment reports if applicable, and a certificate of conformance with every order.
## Send your drawing Send us your 2D drawing or 3D model. We will check the geometry, suggest material and heat treatment if you are unsure, and give you a firm quote within 12 hours.
