Your drawing defines the part. Our job is to make it exactly that way.
We machine C-style collet chuck holders to your print, not to a catalog standard. Every unit is verified before shipment. No exceptions.
We have 20 years of precision manufacturing experience in Dongguan, China. You send the drawing. We handle the rest.
| Parameter | Value |

| Runout | ≤0.005 mm TIR at nose, ≤0.008 mm at 50 mm from nose |
| Taper angle | 16° included angle, ground to AT3 or better |
| Machining process | CNC turning, CNC milling, cylindrical grinding, surface grinding |
| Inspection | CMM report, runout check, hardness test per batch |
| Batch size | 1–50,000 pieces |
| Lead time | Samples: 7 days. Production: 10–15 days |
| Packaging | Anti-rust oil, individual foam wrap, export carton |
We grind the taper after heat treatment. That keeps runout tight and repeatable. The collet seat is lapped to ensure even clamping force across the full circumference.
1. Batch-traceable quality. Each heat number is recorded. Each batch gets a unique ID. If you need to trace a part back to its material lot, we can do it in minutes. No guesswork.
2. Inspection report per batch. You get a full dimensional report with every shipment. CMM data, runout measurements, hardness values, surface finish readings. We do not ship without it. If a dimension is out, we catch it before it reaches you.
3. One factory for CNC, stamping, springs, and heat sinks. Your collet chuck holder is not an isolated part. You may need a spring collet, a stamped retainer, or a heat sink for the spindle drive. We make all of them under one roof. Fewer suppliers, fewer logistics headaches, one quality standard.
Custom CNC collet chucks are not limited to one industry. We machine them for:
In every case, the C-style collet chuck holder is the interface between the machine spindle and the workpiece. If it fails, the whole operation stops. That is why we grind every taper and check every bore.

Q: What is your MOQ? A: No MOQ. We accept single-piece orders for prototypes and low-volume runs. The same tolerance and inspection apply whether you order 1 or 10,000.
Q: How do you ensure tolerance and quality? A: We use CNC turning and milling, then cylindrical grinding for the taper and bore. After heat treatment, we re-grind to final size. Every unit is checked for runout and taper angle. A CMM report is included with each batch.
Q: What is your lead time? A: 7 working days for samples. 10–15 working days for production orders, depending on batch size and material availability. We stock 20CrMnTi and 8620 in common sizes to shorten lead time.
Q: Can you provide material certificates? A: Yes. We supply mill certificates for the raw material with every batch. Hardness test reports are also available on request. If you need full traceability, we can include heat treatment records as well.
We give firm quotes in 12 hours. Not a rough estimate – a real price based on your material, tolerance, and quantity.
