CHD HARDNESS TESTER

LD3000AF

Special hardness tester suitable to test CHD (case hardness depth) in a few minutes, without cutting the sample

Non destructive case hardness depth test CHD

Automatic hardness testing machine with test loads from 10 to 3000 kgf. Hardness measurements conforming to ASTM and DIN EN ISO international standards.

Fully motorized and automatic, the test is not affected by operator influences and can easily be used by operators of every level

CHD HARDNESS TEST WITH HDTL METHOD

Definition of the superficial hardness and its effective depth (CHD) from 0.12 to 1.8 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 and the depth (mm) values at HV525-550-600-650 and more.

UNIQUE ADVANTAGES

CHD on heat treated and hardened parts
Quick case depth directly after quenching
No need to cut, mount and polish the part
Suitable for production floor
Results accuracy better than 0.05mm
Reduce testing costs up to 70% compared to traditional polished cross section as Vickers method
Reduce your testing time by 90%

NOT ONLY CHD!

LD3000AF is a universal hardness tester suitable also for Rockwell, Superficial Rockwell, Brinell HBT and Vickers!

EASY, FAST AND AUTOMATIC

Spin the leveling screw until the sample in blocked by the clamping hood. Press the START button and the measuring head will approach the specimen, applies the loads, goes back and show the result; all in automatic succession without breaching a phase. Direct auto-reading Rockwell, Superficial Rockwell, Brinell HBT and Vickers HVT.

SELF COMPENSATING AND CLAMPING SYSTEM (Pat. AFFRI)

When testing unstable samples or deflective parts, the AFFRI System will follow the sample without loosing contact, thus compensating any deflection during the test cycle. Thanks to the auto-compensation and the infinite indenter stroke, accurate results are assured even with oiled, dusty or dirty pieces.

CLOSED LOOP TECHNOLOGY (Pat. AFFRI)

Load forces are applied through load cells and electronically controlled in “Closed Loop” with a frequency of 1 khz, assuring perfect linearity in every range. The test load accuracy is not affected by any structural deflection, misalignment, vibration or problems associated with dead weight systems on traditional
testers. The tester can also run in an inclined position.

Excellent measurement precision & accuracy on the first test. No need to obtain an average hardness value!
