Surface Finish

Surface treatment is a crucial step in CNC machining, significantly improving the appearance, durability, and functionality of machined parts. Various surface treatment processes, such as anodizing, sandblasting, polishing, electroplating, passivation, and powder coating, can enhance properties like corrosion resistance, wear resistance, surface hardness, and visual appeal.

This guide introduces the most commonly used surface treatment methods for CNC-machined parts, their advantages, material compatibility, and how to select the appropriate CNC surface treatment process based on application requirements, tolerances, and production needs. Furthermore, this guide explains how surface treatment affects machining accuracy and how Xtproto provides integrated CNC machining and surface treatment solutions for high-precision parts.
