The surface roughness is closely related to the matching properties, wear resistance, fatigue strength, contact stiffness, vibration and noise of mechanical parts, and has an important impact on the service life and reliability of mechanical products. Therefore, after the casting is formed, its surface roughness needs to be tested to ensure normal use.
