Scope of Service

Capability Highlights

Accuracy to ±0.005mm verified on a CMM. Machine park includes 3/4/5-axis machining centers, CNC lathes and Swiss-type machines, with in-house fixture design and CAM simulation for first-pass success.

Quality System

Every order ships with in-process inspection records. Our CMM verifies critical dimensions against your drawing on first article, at batch start, and at final release. Material certificates (EN 10204 3.1) and full dimensional reports come standard; PPAP and FAIR documentation are available on request for automotive and industrial programs.

Lead Time & Packaging

Standard lead time is 3-7 days for prototypes and 7-15 days for production batches, with surface treatment adding 5-10 days. Parts are cleaned, protected against corrosion and scratching, and packed in customized trays or EPE foam for international shipping. DFM feedback on RFQs is returned within 24 hours.

Why Customers Stay

One supplier from drawing to finished part: milling, turning, 5-axis and Swiss-type machining are all in-house, together with anodizing, plating, laser marking, and silk-screen coordination. You get one accountable partner instead of a chain of subcontractors.

Frequently Asked Questions

What is the difference between standard and precision CNC machining? Standard CNC machining typically achieves +/-0.02-0.005mm tolerance, suitable for general industrial applications. Precision CNC machining achieves +/-0.005-0.005mm tolerance, required for optical systems, medical devices, industrial components, and precision instrumentation.

How does CHX Metal ensure consistent precision across batches? CHX Metal uses a coordinate measuring machine (CMM) for dimensional, statistical process control (SPC) on critical processes, calibrated tooling with +/-0.005mm positioning accuracy, and temperature-controlled workshops (20+/-2 degrees C) for ultra-precision parts.

What materials does CHX Metal machine for precision applications? CHX Metal machines aluminum alloys (6061, 7075), stainless steels (303, 304, 316, 316L), titanium alloys (TC4, Grade 2), brass (C360, C260), copper alloys, tool steels (D2, H13), and engineering plastics (PEEK, POM, Nylon). We also work with Kovar, Invar, and other specialty alloys.

What inspection capabilities does CHX Metal offer? CHX Metal offers full CMM inspection with a coordinate measuring machine (CMM), surface roughness measurement (contact and optical), hardness testing, torque testing, and material composition verification. Full inspection reports with measurement data are available for every batch.

What is the typical lead time for precision CNC parts? Prototype delivery: 3-7 days. Small batch (1-100 pcs): 7-15 days. Mass production (1000+ pcs): 15-30 days. CHX Metal offers rush services for time-critical projects, and DFM feedback is provided within 48 hours of receiving your drawings.
