Leeb hardness tester

Leeb hardness tester The Leeb hardness tester is a special test instrument for measuring the hardness of materials. It is mainly used to measure metal materials. In 1978, the Swiss Dr. Leeb first proposed a new hardness test method. The basic principle is that the impact body with a certain mass impacts the surface of the sample under a certain test force, and the disperser is measured at a distance of 1 mm from the surface of the sample. The impact speed and the rebound speed, using the electromagnetic principle, induces a voltage proportional to the speed.
According to the principle of the Richter hardness tester, as long as the material has a certain rigidity, the roughness of the roughness meter can be formed, and the accurate hardness value can be measured. Bending Tester Because many materials have no corresponding conversion to the hardness of other systems, the Leeb hardness tester currently only has a conversion table of 9 materials. The specific materials are as follows: steel and cast steel, alloy tool steel, gray cast iron, ductile iron, cast aluminum alloy, copper-zinc alloy, copper-tin alloy, pure copper, stainless copper.
In actual production, the metal materials used are various. Because the Leeb hardness tester is sensitive to the processing method of the material and the alloying element composition of the material, the hardness conversion table stored in the Leeb hardness tester chip cannot meet the needs of the user. In the test, the user can use the fitting software to make his own special hardness conversion table.
