Since 1954 AFFRI® has been producing hardness testers where the force is generated by load cells instead of traditional dead-weight loads and elevating screws. Combine this technology with innovative components and the result is the unique AFFRI SYSTEM®.
The AFFRI SYSTEM® has consistently been protected by registered patents. An increase in the operative performances was obtained with the use of a controlled load cell in a closed-loop system (Patent AFFRI N. 1175158). However this improvement appears moderate if we compare it with the high qualitative and operative level reached by the AFFRI SYSTEM®. A further improvement in performance was achieved when AFFRI® automated the Rockwell and Brinell hardness tester. The automation process starts with only one control button and no break in positioning, approach and execution of the test. The fully automatic operation and the rapid speed obtained by the AFFRI SYSTEM® remains unchanged regardless of the load cell version. This is due to the use of unprecedented technologies (patent pending) used in the system.
ALL OPERATIONS ARE MANAGED BY A SINGlE DRIVE INCLUDING AUTOMATIC CONTACT WITH TEST PIECE
Secure contact with the specimen is always maintained, even in the unlikely event of any specimen movement during the operation cycle.
Push the start button and the AFFRI® System moves down to make contact with the test surface from long distances and automatically starts the hardness test cycle in automatic succession without breaching a phase.
The measurement cycle progresses as follows:
• approach the test piece • activation of reference surface • clamping of the piece
• entire test cycle performance • release of the test piece
The entire test cycle is complete and the results appear on a large display. Fully motorized and automatic, the test is not affected by operator influences and can easily be used by operators of every level.
