Ruixing MFG - Custom CNC Machined Parts Manufacturer & Supplier For 20 Years
Ra 0.8 μm can be achievable for suitable machined surfaces, but surface roughness depends on material, tool geometry, machining parameters, tool condition and the geometry of the surface.
A narrow internal pocket, deep cavity or difficult-to-access feature may have different achievable roughness from a large flat external surface.
If a specific surface requires Ra 0.8 μm or another roughness value, the requirement should be identified on the drawing.
We can also provide additional finishing processes such as polishing, electropolishing, grinding or other treatments where appropriate for the application.
