A special jig from Indentec enables the outer edges of thin discs to be repeatably hardness tested under completely stable conditions It consists of a triple legged right angle fixture with a horizontal peg in the upright face
For hardness testing, the disc is mounted on its internal diameter on the peg.
This gives positive support to the specimen while the indenter is applied for the test, the jig's three legs ensuring stability on the test table.
The jig is being used by one heat treatment company to make Rockwell tests in the tooth roots of thin roller chain sprockets.
A special chisel profiled indenter has been provided by Indentec to reach into the narrow gaps between the teeth.
