Automatic hardness tester for Vickers HDTL CHD method

LD 3000 AF

Automatic hardness tester for Rockwell, Brinell, Vickers and CHD test methods in compliance with ASTM and ISO hardness standards. The LD 3000 AF is built for measuring the thickness of the superficial hardness and will determine (CHD) Case Hardness Depth from 0.12 mm to 2 mm, with no need to destroy the specimen or to separate material types before performing the test. With just one measurement it reduces hardness testing time and costs compared to traditional polished cross section of Vickers and knoop methods. Load forces are applied through load cells and electronically controlled in Closed Loop (Pat. Affri). This hardness tester is entirely motorized and it is equipped with a wide touchscreen for ease in test planning and a clear view of results. Statistics and CHD charts are automatically generated and can be stored with the test session in the large archive. User friendly interface with conversion tables and round correction values for tests on covex cylindrical surfaces or various diameters. For hardness case depth test with non-destructive method on all metals: Iron, steel, tempered steel, cast iron, brass, aluminum, copper and metal alloys. Heat treatment, hardening, nitriding, cementation and hardfacing.

HDTL Method

HDTL CHD charthardness tester HDTL CHD screenDefinition 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 (Pat. AFFRI)

Hardness tester Closed LoopThe 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 and fast automatic measurements:

Durometro Durezza Vickers HDTL con schemo touchscreenDurometro Durezza Vickers HDTL prova su ingranaggiSpin 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.
