Overview

About the LD3000AF

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

HBWT2.5/62.5 – HBWT2.5/187.5 – HBWT5/125 – HBWT5/250 – HBWT5/750 – HBWT10/500 – HBWT10/1000 – HBWT10/1500 – HBWT10/3000 – HBW1/10 – HBW1/30 – HBW2.5/62.5 – HBW2.5/187.5 – HBW5/25 – HRW5/62,5 – HBW5/125 – HBW5/250 – HBW5/750 – HBW10/100 – HBW10/250 – HBW10/500 – HBW10/1000 – HBW10/1500 – HBW10/3000

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.

Testing methods

Supported methods documented by AFFRI

Case hardness depth (CHD) — HDTL method
Rockwell (ISO 6508 / ASTM E18)
Brinell HBWT — depth (ISO 6506)

Technical notes

CHD by the HDTL method is a non-destructive evaluation developed by AFFRI; it is not the cross-section Vickers traverse defined in ISO 2639. Confirm correlation with your reference method before adopting it.

Technical detail

How the LD3000AF works

CHD Hardness Test With Hdtl Method

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!

Ld3000Af Software

Everything is under control! The pre-installed software drives the whole instrument during the entire hardness test cycle.

Wide touchscreen gloves sensitive
User friendly Windows® interface designed inhouse
Conversion tables ASTM, ISO and general
Round correction values for tests on convex and cylindrical surfaces
Statistics and CHD charts are automatically generated
All results and testing sessions can be stored on the archive
Color highlighted results (low/ok/high)
Export results to PDF, TXT, CSV, XLS, and more
Data enter via code bar scanning
Outputs via RS232, USB, and Ethernet
