0.5HR Resolution Manual Loading Rockwell Hardness Testing Machine Max Vertical Space 400mm
Applications:
Rockwell hardness measurement of ferrous metals, non-ferrous metals
and non-metallic materials.
Wide range of applications, suitable for rockwell hardness testing
of hardening, quenching and other heat-treated material.
XRock-150M is suitable to determine the Rockwell hardness of ferrous, non-ferrous metals and non-metal materials. It can be widely applied in the Rockwell hardness testing for heat treatment materials, such as quenching, hardening and tempering, etc.
Mainly Functions:
● Lever Loading, manual operation, durable and reliable.
● No friction spindle, high precision test force.
● Precision hydraulic buffers, steady load.
● Dial display the hardness value, HRA, HRB, HRC, and can choose
other Rockwell Scale.
● Accuracy according to GB / T230.2, ISO 6508-2 and American ASTM
E18 standard.

The Rockwell test consists of measuring the additional depth to which a carbide ball or diamond penetrator is forced by a heavy (major) load beyond the depth of a previously applied light (minor) load (SET point).
The minor load is applied first and a SET position is established on the dial gauge or displacement sensor of the Rockwell tester. Then the major load is applied. Without moving the piece being tested, the major load is removed and, with the minor load still applied, the Rockwell hardness number is automatically indicated on the dial gauge or digital display.
The diamond penetrator is used for testing materials such as hardened steels and cemented carbides. The carbide ball penetrators, available with 1/16 inch, 1/8 inch, 1/4 inch, and 1/2 inch diameter, are used when testing materials such as steel-copper alloys, aluminum and plastics to name a few.
Rockwell testing falls into two categories: Regular Rockwell testing (e.g., C and B scales) and Rockwell superficial testing (e.g., 30 N and 30 T scales).
High Rockwell hardness numbers represent hard materials and low numbers soft materials.
