Gar C9 | Surface Roughness Scale C-9 Cast Mocrofinish Surface Comparator

Gar Electroforming is the largest and longest established electroforming service center in the U.S. Through their years of experience in manufacturing, design, and development of electroforming processes and products they have created a unique lineup that have become the standard in their respective categories. They are cheifly known for their microfinish comparators that help to verify surface roughness in the manufacturing process. Their microfinish comparators are second to none in the industry. You can view their lineup here.

C-9 Cast Microfinish Comparator: Nine replicated cast surface finish specimens ranging from 20 to 900 microinches.

The C-9 Cast 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 C-9 Cast 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 cast surfaces is required.

The C-9 Cast 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

UNIFORMITY AND ACCURACY

The original masters and the electroformed replica production masters have been checked at evenly distributed intervals. Sufficient measurements were taken to determine a representative average. The rating listed is the average of these readings.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.

Features

• Manufacturer Part # C9
• Weight: 0.22 lbs.
• Place the microfinish comparator surface roughness scale alongside your work piece. Slide the scale so that the rectangle with the surface roughness you want is adjacent to the piece you are examining.
• Compare by drawing the tip of the fingernail across each surface at right angles to the tool mark.
• The feel of the fingernail contact must be the same if the finishes are identical.
• There are nine replicated cast surface finish specimens ranging from 20 to 900 microinches.
• The C-9 cast microfinish comparator is rectangular in shape (4 1/2"x 3 1/4") and is a corrosion resistant electroformed nickel duplicate of actual cast surfaces.
• Supplied in a leatherette case with engineering data and instructions.
• Made in USA.
