Definition of the superficial hardness and its effective depth (CHD) from 0.12 a 2 mm. LD 3000 AF will determine the Case Hardness Depth (CHD) with great precision and minimal operator intervention, on finished products, without destroying the specimen and testing rather than random sampling of manufactured products. There's no need for sample preparation, no need to separate material types or to polish the cross section as in the Vickers method. In just one minute the tester generates the report with the CHD graph.
CLOSED LOOP TECHNOLOGY (PAT. AFFRI)
The force by load cell and the closed loop AFFRI system assures absolute accuracy on all test conditions. Closed Loop load cells manage load forces, which are automatically programmed and controlled at each test assuring perfect linearity in every range eliminating the problems associated with dead weight systems on traditional testers. Results are not affected by any structural deflection, misalignment or vibration. The system can also operate in an inclined position.
EASY & FAST AUTOMATIC MEASUREMENT
Spin the leveling screw handle until the sample makes contact with the clamping hood blocking the piece. Press the START button and the measuring head will approach the specimen, apply the load to perform the indentation and goes back upward; all in automatic succession without breaching a phase. When testing unstable samples or deflective parts, the AFFRI System will follow the sample and not lose contact, compensating any frame deflection during the test cycle. Accurate results are assured even with oiled, dusty or dirty pieces.
