Polishing

Achieves a superior mirror-like aesthetic while significantly reducing surface friction and bacterial adhesion. It eliminates microscopic abrasions, making it the ideal choice for medical devices and high-end decorative hardware where cleanliness and “shelf-appeal” are critical.

Sandblasting

Delivers a consistent, non-reflective matte finish that effectively masks machining tool marks and surface imperfections. This process creates an ideal surface profile (roughness) that dramatically improves the adhesion strength of subsequent coatings or paints.

Brushed Finish

Creates a distinct linear grain that enhances the premium feel of metal parts. Beyond its decorative value, the brushed texture is highly functional for masking fingerprints and minor scratches, ensuring components maintain a pristine look even in high-touch applications.

Hard Anodizing

Transforms the aluminum surface into an exceptionally hard, ceramic-like layer. It provides superior wear resistance for moving parts and excellent electrical insulation, while offering robust protection against harsh environmental corrosion without compromising part integrity.

Passivation

A critical chemical treatment for stainless steel that removes free iron from the surface, preventing rust and oxidation. Since it does not add any thickness, it is the go-to solution for high-precision components that require maximum corrosion resistance while maintaining strict dimensional tolerances.

Black Oxide Coating

Provides a durable, non-reflective black finish with zero dimensional change, ensuring that tight-tolerance threads and assemblies fit perfectly. It offers cost-effective corrosion resistance and is widely used for optical equipment to eliminate light glare and reflections.

FAQs
for Precision Machining

What is precision machining?

Precision machining is a manufacturing process that produces components with tight dimensional accuracy using advanced CNC equipment and controlled processes.

Chiheng provides precision CNC machining with tolerances down to ±0.005mm depending on part design, material, and manufacturing requirements.

We work with a vast range of materials, including Aluminum (6061, 7075), Stainless Steel (304, 316, 17-4 PH), Titanium, Brass, and Copper. We also specialize in high-performance plastics such as PEEK, POM (Delrin), Nylon, and Polycarbonate.

Our standard lead time is 3–5 business days for rapid prototyping and 2–3 weeks for mass production runs. We also offer expedited services for time-critical projects to help you meet tight market deadlines.

No, we have no minimum order requirements. Whether you need a single functional prototype to test your design or a production run of 10,000+ units, we provide the same level of precision and quality commitment.

Quality is our top priority. We are ISO 9001 certified and conduct rigorous inspections at every stage—from raw material verification to final CMM testing. We can provide Full Inspection Reports (FAI) and Material Certifications upon request to ensure 100% compliance.
