Gar E-9 Electrical Discharge Machined Microfinish Comparator (EDM)

Electrical Discharge Machined Microfinish Comparator (EDM): Nine replicated EDM surface finish specimens ranging from 16 to 250 microinches.

The E-9 MICROFINISH COMPARATOR Surface Roughness Scale provides an economical tool which permits roughness to be specified on the same basis as linear measurements. The surfaces presented are the result of years of research and engineering. Details covering this subject are now published in The American National Standards Institute (ANSI) specification titled: "Surface Texture, Surface Roughness, Waviness and Lay". ANSI/ASME B46.1

The E-9 MICROFINISH COMPARATOR Surface Roughness Scale is made by a dual electroforming process wherein nickel is electrodeposited to provide an exact reproduction in intricate detail. The same electroforming process used to produce the Surface Roughness Scale is available from GAR Electroforming to serve your product needs.

The surfaces used in this scale are reproductions of accurately electrical discharge machined surfaces on oil-hardening tool steel measured in microinches (millionths of an inch- 0.000001"). The numbers engraved alongside each surface are the average deviation from the mean surface expressed in microinches.

The E-9 MICROFINISH COMPARATOR Surface Roughness Scale provides industry with established flat surface roughness specimens for visual and tactual comparison. It is used in specifying and controlling surface roughness when a product having the appearance of typically EDM surfaces on tool steel, is required.

This MICROFINISH COMPARATOR Surface Roughness Scale is a patented item and is a product of the engineering skill and precision workmanship of GAR Electroforming Division.

The E-9 EDM MICROFINISH COMPARATOR is rectangular in shape (7/8" x 5") and is a corrosion resistant electroformed nickel duplicate of actual electrical discharge machined surfaces.

There are nine replicated EDM surface finish specimens ranging from 16 to 250

The E-9 MICROFINISH COMPARATOR is supplied in a leatherette case with engineering data and instructions
