You send the drawing. We machine the part. Every HSK100 ER40 collet chuck is verified for taper contact and runout before it leaves our floor.
This is a precision manufacturing job, not a commodity order. We hold the tolerances that keep your spindle running true and your tool life predictable.
At a glance: HSK100 shank, ER40 collet seat, runout ≤ 0.005 mm at nose, hardness 58–62 HRC, lead time 15–20 days, no MOQ.
| Parameter | Value |

| Shank type | HSK100 (DIN 69893) |
| Collet seat | ER40 (DIN 6499) |
| Runout (TIR at nose) | ≤ 0.005 mm |
| Hardness | 58–62 HRC (case hardened) |
| Surface finish | 0.4 µm Ra on taper, 0.8 µm Ra elsewhere |
| Balancing | G2.5 @ 25,000 rpm (optional) |
| Key process | CNC turning, 5-axis milling, jig grinding, centerless grinding |
| Inspection | 100% taper gauge check, CMM report per batch |
| Batch size | 1 to 5,000 pieces |
| Lead time | 15 days for prototypes, 20 days for production |
| MOQ | No MOQ |
We use 5-axis CNC mills and jig grinders for the taper and bore. Heat treatment is done in-house with a vacuum furnace. Every chuck is serialized for traceability.
1. Batch-traceable quality. Each heat lot and machining batch gets a unique code. If a tool holder fails in your spindle, we can trace it back to the raw material certificate, the machine operator, and the inspection record. No guesswork.
2. Inspection report per batch. You get a dimensional report with actual measured values, not just a pass/fail sticker. Taper contact, runout, hardness, and surface roughness are all documented. We keep records for 10 years.
3. One factory for CNC, stamping, springs, and heat sinks. You are not managing four suppliers. Send us a complete assembly drawing. We machine the chuck, stamp the retention knobs, make the springs for the collet closer, and machine the heat sink if your spindle needs cooling. One purchase order, one shipping date, one responsible party.
HSK100 ER40 collet chucks are used in heavy-duty milling and drilling centers. Typical applications include:
In all these cases, the chuck is the interface between the spindle and the cutting edge. If it flexes, you get chatter. If it runs out, you get oversized holes and short tool life. Our job is to make that interface disappear.

Q: What is your MOQ? A: No MOQ. We make one piece for a prototype or 5,000 for production. Same process, same inspection.
Q: What tolerance can you hold on the HSK taper and the ER40 bore? A: Standard is AT3 for the HSK100 taper and ≤ 0.005 mm TIR at the collet nose. We can go tighter to AT2 if your spindle requires it. Tell us your drawing tolerance, we will meet it.
Q: What is your typical lead time? A: 15 days for a prototype, 20 days for production runs. If you need a rush, we can quote 7-day delivery for standard materials. We do not sacrifice inspection to hit a date.
Q: Do you provide material certificates and heat treatment reports? A: Yes. Every batch ships with a mill certificate for the raw material, a heat treatment report showing hardness and case depth, and our dimensional inspection report. All documents are in English.
