Introduction


According to the Brinell hardness test principle, applying the test force by hammer impact, exactly controlling the test force by a shear pin, leaving a round Brinell indentation on the test piece after testing, reading out the indentation diameter by the reading microscope, check the hardness table to get the correct Brinell hardness value.
According to the similarity principle of Brinell hardness testing, this tester employs 1580kg test force, Ф7.26mm ball indenter, F/D2=30, the test condition is equivalent to the commonly used 3000kg test force, Ф10mm ball.
The test force is great, so the roughness of the surface does not matter much.
The test result has good stability and repeatability thanks to the exact control of the test force.
The test error is 5~6% of it, the accuracy is far higher than the old type hammer impact Brinell hardness tester.
The testing cost is low by using only 1 cheap shear pin in each test.
Easy, simple operation and quick testing without sampling.
It can be used for testing the hardness of large-size, inconvenient-to-move or unable-to-cut forgings, castings etc.
