1. Batch-traceable quality. Every heat lot and material certificate is recorded. Each batch gets a unique job number. If you need to trace a part back to its raw material, we can do it in minutes. This matters for aerospace, medical, and automotive audits.
2. Inspection report per batch. You get a dimensional report with every shipment. Not a generic certificate — an actual list of measured values against your tolerances. We use CMM, optical comparators, and air gauges. If a dimension is out, we catch it before packing, not after you install it.
3. One factory for CNC + stamping + springs + heat sinks. Your assembly may need a CNC collet chuck, a stamped retainer plate, a compression spring, and an aluminum heat sink. Instead of coordinating four suppliers, you send us the whole package. One purchase order. One shipping date. One quality standard. We have run all four lines under one roof for 20 years.
Swiss-type CNC collet chucks and guide bushings are not shelf items. They are wear components in high-precision turning centers. Typical applications:
If your machine uses a guide bushing, you know the pain of premature wear. We make the replacement that lasts 3–5 times longer than standard HSS, depending on material and coolant.

Q: What is your MOQ? A: No MOQ. We machine one prototype or a million pieces. The unit price drops with quantity, but we never turn away a single-piece order.
Q: How do you guarantee tolerance and quality? A: We inspect 100% of critical dimensions on every part. A CMM report is included with each batch. If you request it, we also provide material certificates and hardness test results. Our tolerance is ±0.005 mm on bores and ±0.003 mm TIR on concentricity.
Q: What is the lead time for a custom CNC collet chuck? A: Prototype (1–5 pieces) ships in 7 days. Production runs ship in 15 days. For urgent breakdowns, we can expedite to 72 hours for standard sizes. Just tell us the machine model and we will check our stock of semi-finished blanks.
Q: Can you provide material certificates? A: Yes. Every tungsten carbide and steel batch comes with a mill certificate. We keep records for 10 years. If your customer requires full traceability, we provide it without extra cost.
