Description

Master Visual-Tactual Set: Eight individual blocks with fifteen replicated machined surface finish specimens ranging from 2 to 125 microinches.

The M-15 Master Set contains eight individual rectangular blocks (each measures 1 3/8" x 1 7/8"). They are made of corrosion resistant electroformed nickel that are duplicates of actual conventionally machined surfaces. There are fifteen replicated machined surface finish specimens ranging from 2 to 125 microinches.

The M-15 Master Visual-Tactual Set is supplied in a protective velvet-lined case complete with engineering data and instructions. Individual blocks are available and can be purchased separately.

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.
