| Surface Roughness Chart

Surface roughness Ra refers to the measurement of surface deviation from a mean height. A lower Ra value indicates a higher quality surface with less deviation. However, achieving a lower Ra measurement typically requires additional machining processes. Generally, workpieces produced using CNC lathe or milling can achieve a surface roughness between Ra 0.8-3.2.

In terms of our CNC machining capabilities, we can manufacture aluminum alloy parts with a surface roughness ranging from Ra 0.1-0.2, meeting the requirements for optimized piston movement in an ABS system. Our standard supply for machined parts falls within the Ra 0.8-3.2 range. It’s worth noting that higher-grade surface roughness comes with increased production costs.
