What is surface roughness in press molds? An explanation of the meaning of symbols and measurement methods!
This time, I will explain "surface roughness," which is essential in metal processing. Drawings always include symbols or indications that specify the desired surface roughness. I will explain what the indicated surface roughness actually means using photographs. Additionally, I will introduce which machine tools can generally achieve what level of surface roughness. When processing a surface, be sure to check if the machine is suitable for the desired surface roughness.
