AFFRI 270 VRSD - 270 VRSA - 270 VRSTV

UNIVERSAL HARDNESS TESTER

AFFRI® introduces a system of automatic hardness tester for the future
Since 1964 AFFRI® has being producing hardness testers.
An increase in the operative performances has been obtained with the use of control load cell in closed-loop (Patent AFFRI N. 1175158).
However this improvement appears moderate if we compare it with the high qualitative and operative level reached by AFFRI SYSTEM®.
A further improvement in performances was achieved when AFFRI® made really
automatic the hardness tester working in Rockwell, Brinell and Vickers tests : only one drive starts up and performs - without a break - the phases of positioning, approach and execution of the test.
The fully automatic operation and the speed in the whole test cycle, obtained by AFFRI SYSTEM®, remains unchanged even in the version with load cell due to the use of unprecedented technologies.

All operations are managed by a single drive including automatic research of test piece
-  Pushing the Start button,
270 VRSTV head moves down to reach the test surface from distance multiples of 50 mm and automati-cally starts the hardness test cycle in automatic succession without breaching a phase:
-  approach to the piece;
-  clamping of the piece;
-  activation of reference surface;
-  entire test cycle performance and release of piece.
-  Does not require elevating screws
-  Meets all laboratory requirements
-  Full operation even in presence of vibrations, sudden changes in temperature or dusty environments.
-  Perfect and effective measure¬ments even at the first test
-  Insensitive to deflection
-  Optical gauge high definition 0.1 Micron mm for very accurate Vickers and Brinell measurements
-  Automatic compensation of deflection up to 50 mm
-  It meets all laboratory requirements.
-  Full operation even in presence of vibrations, sudden changes in temperature or dusty environments.
-  Unparalleled accuracy, R&R Repetability and Reproduction in all test conditions (0.1 HV) which can be checked in operation condition
-  Survey of load and indenter penetration in axis, in order to obtain an absolute hardness measurements.
-  Automatic control and selection of pre-loads and loads through a software in closed-loop with load cell (AFFRI® Patent).
-  The operator can automatically select test load and measure scale through only one button.
- Simultaneous conversion different scales (Rockwell, Brinell, Vickers and in N mm2)
-  Automatic load application and selection
-  Large working table 330x390 mm permits to support small and large parts till 2000 kg weight
-
Software includes settings in three selection classes in order to simplify the insertion of the instrument in an automated working line.
-  Automatic correction of measurements on round surfaces and memorisation of results.
-  Reversibility from automatic to semiautomatic for single test
