Custom tolerances can be achieved based on material, geometry, and production requirements.
We offer a variety of surface finishing options for CNC turned parts to improve appearance, durability, and performance.
- Anodizing – Enhances corrosion resistance and surface hardness (for aluminum parts)
- Electroplating – Zinc, nickel, or chrome plating for improved corrosion and wear resistance
- Polishing – Achieves smooth and shiny surfaces for precision components
- Sandblasting – Uniform matte finish and removal of machining marks
- Black Oxide – Provides mild corrosion resistance for steel parts
- Brushing – Creates a consistent linear texture for decorative finishes
Custom surface finishes are available based on your requirements.

CNC Machining Tips
C65500 high silicon bronze is a unique and often misunderstood type of copper alloy. In engineering, it is defined less by traditional categories and more by its unique performance profile.
-
Complete guide to engineering plastics — covering POM, nylon, PC, PEEK, PPS classification, property comparison, CNC machining parameters, injection molding considerations, and a structured selection framework for manufacturing applications.
-
Compare brass, bronze, and copper — covering conductivity (copper 100% IACS), CNC machinability (brass 40–50% faster), wear resistance (bronze 3–6× bushing life), corrosion (dezincification risk in brass), cost analysis, applications, identification methods, and material selection guide.
