表面粗糙度比较样块
Comparison Sample Block of surface Roughness
用途:
表面粗糙度样块是以比较法来检查机械零件加工表面粗糙度的一种工作量具。通过目测或放大镜与被测加工件进行比较,判断表面粗糙的级别。
APPLICATIONS:
Comparison Sample Block of surface Roughness is a measuring tool which is sued to check the smooth finish of a mechanical workpiece by comparision method and eye estimation or microscope is used to compare an detect the degree of the surface roughness.
