Once the machining process is complete, tiny visible tool marks will appear on the surface of the CNC machined part, known as the “as-machined” or “as-milled” surface. The processing surface roughness (Ra) is standardized to 1.6-3.2μm, and the surface finish requirement can be increased to 0.8-1.6μm or higher (0.2-0.8μm), but this will require more operating time and higher cost. Leadpoint can provide you with professional advice based on your different surface finish requirements, contact us today for more information.
