AFFRI Hardness Tester LD3000 AF

AFFRI Hardness Tester LD3000 AF

฿0.00

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.

CONFORMS TO: ISO 6508 - ASTM E18 / ISO 6506 - ASTM E10 / ISO 6507 - ASTM E384
LD 3000 AF meets all the worldwide rigorous hardness testing standards

EASY AND FAST AUTOMATIC MEASUREMENTS
Spin the leveling screw’s handle and bring your sample to make contact with the clamping hood blocking the piece. Press the START button and the measuring head approaches the sample, applies the load to perform the indentation and goes back upward; all in automatic succession without breaching a phase. Direct auto-reading of Rockwell, Superficial-Rockwell, Brinell HBT and Vickers (only indentation).

ADVANTAGES:

• Non-destructive CHD test
• No need to prepare the sample or to separate materials types
• Reduce testing costs up to 70% compared to traditional polished cross section as Vickers method
• No need for sample preparation equipment and consumable supplies
• Increase your product quality, 100% inspection testing on production floor department
• Reduce your testing time by 90%, just 60 seconds analysis time
• Not only CHD! LD3000AF is a universal hardness tester for Rockwell, Superficial-Rockwell, Brinell HBT and Vickers (only indentation)


  LD 3000 AF WILL DETERMINE THE CASE HARDNESS DEPTH (CHD), WITH GREAT PRECISION AND MINIMAL OPERATOR INTERVENTION.

Testing can be performed on a non-metallographic prepared specimen. The system will determine the superficial hardness and its effective depth (CHD), from 0.12 to 2 mm, without destroying the specimen and testing rather than random sampling of manufactured products. Great precision and minimal operator intervention on finished products: there’s
no need for sample preparation, no need to separate material types or to polish the cross section as Vickers method. In just one minute the tester generates the report with the CHD graph.

HTDTL software version, supplies the Hardness and hardness depth values at HV2 525-550-600-650. The HTDTL Plus version in addition, offers the complete report and graph, assisting in displaying the complete sample decarbonized zone.

LD3000AF performs every hardness scale for universal use in your own laboratory.
 

 

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.

SELF COMPENSATING AND CLAMPING SYSTEM (Pat. AFFRI)

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. The indenter head retracts into a protective
cylinder at the end of the measurement cycle. Total indenter head travel of 30mm max. With a total sample height accommodation of 300mm.
