These surface roughness is used to compare and determine the degree of the surface finish by comparision method and eye estimation or magnifying glass.The surface rough contast blocks is made of 45 carbor steel except the GCr15 which is using to plat lapping the sample block. All 30 speciments are calibrated in u''AA (Arithmetical Average) and in the metric equivalents um Ra. ========== is_customized : None Model Number : TA1620 Graphic : Bearing area curve, Roughness profile, Primary profile Filter : RC,PC-RC,Gauss,D-P The sampling length(lr) : 0.25, 0.8, 2.5mm Accuracy : Less than ±10% Repeatability : Less than 6% ProductSiteLaunchDate : 2024-08-01T05:37:52.718Z Size : One Size UnitCount : 1
