  •    Overall dimensions of each plate 52mm x 128mm (or 2 1/16" x 5")
  •    Light in weight - can be carried in pocket. Supplied in a plastic wallet.

Model NO. 16010

Machining Method: cylindrical grinding
No. of Specimens: 8
Range Ra µm: .025-3.2
Range AA µ": 1,2,4,8,16,32,63,125
N Numbers: 1-8

TYPE:
The specimens are electroformed replicas of original edm'ed surfaces.

MATERIAL:
This MICROFINISH COMPARATOR Surface Roughness Scale is made of nickel. It will not corrode.

APPEARANCE:
Each specimen has the surface roughness characteristics of a turned metallic material.

SURFACE ROUGHNESS:
Means the finely spaced surface irregularities produced by the cutting action of the tool edges, the feed of the machine tool and by abrasive grains.

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.

LAY:
This is the term to designate the direction of predominant surface irregularities.

FLAWS:
These are the irregularities which may appear at frequent intervals. They are not typical of a turned surface.
