500N automatic hardness tester for circular blanks


The test execution and evaluation is carried out in accordance with DIN EN ISO 6507 (Vickers) in the load range from 50 N to 300 N.   The system has been designed to make an upgrade with the registering hardness testing (Martens) possible.

At the request of the hardness tester, the test objects are fed to the measuring position and clamped. For optical measurement, the circular blanks are fed to the automatic optical measurement location after setting the indentation (optional after the HM test). With the "CoinFlip" evaluation software, the depth of an indentation can be calculated in Vickers and converted into Martens. In the additional optical evaluation, the hardness indentation is measured and the hardness value determined in Vickers or Brinell depending on the respective test procedure. 

 Circular blanks with determined hardness values outside the tolerance range can be transported on a separate track.  The circular blanks can be tested manually without feedback to the database of the test station. 

After ending the test batch, it is possible to export the ascertained results into Excel in the operational network or to print a protocol.
