表面粗糙度比較樣塊

Comparison Sample Block of surface Roughness

用途：

     表面粗糙度樣塊是以比較法來檢查機(jī)械零件加工表面粗糙度的一種工作量具。通過目測或放大鏡與被測加工件進(jìn)行比較，判斷表面粗糙的級別。

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.
