SURFACE FINISH SPECIMENS: This surface roughness specimen set is ideal for checking, identifying, and specifying the degree of roughness of machine parts.
features 30 different specimens for flat lapping, reaming, grinding, turning, horizontal and vertical milling.
DIMENSIONS: The surface roughness specimens feature grade AA values displayed in microinch and micron values accurate to within ±12% of the nominal values.
each of the 30 specimens made of electro-formed solid nickel is 0.875" by 0.375" in size.
EASY COMPARISON: Each type of surface finish is accurately and consistently reproduced to give the operator a realistic idea of the feel, appearance, and texture of the machined components.
they can be easily compared with a loupe or by utilizing the scratch test.
