Vickers Hardness Tester

 

 

Vicker’s hardness tester is a simple instrument to test the hardness value of metalsaccording to Vicker’s Principle ISO 6507 and ASTM E92.Also can measure the diagonal distance of the indentation, the testing load. It is widely used in metallurgy, forging, casting, hardness steel and nonferrous metals industries, as well as in the laboratories, universities, college and scientific research institutes.

Product Introduction
 
Auto Turret Vickers Hardness Tester

1. Utilizes an 8-inch touchscreen and high-speed ARM processor for intuitive display, user-friendly interaction, and easy operation.

 

2. The machine body is cast in one piece using high-quality cast iron and undergoes automotive paint treatment, resulting in a sleek and attractive appearance.

 

3. Measurement device employs a grating displacement sensor, displaying results on an LCD screen, allowing for adjustments to test scales, test force, indenter type, dwell time, and unit conversion.

 

4. Capable of conducting Brinell, Rockwell, and Vickers hardness tests with multiple test forces to meet diverse hardness testing requirements.

 

5. Electronic closed-loop control of the test force application enables automatic loading, holding, and unloading operations.

 

6. High-definition measuring and observation optical systems combined with a built-in length encoder allow for one-touch measurement of the diagonal line of the indentation, reducing human operational interference and reading errors.

 

7. Built-in testing software for correcting machine hardness values.

 

8. Convenient control system capable of automatic unit conversion across the entire hardness scale.

 

9. Equipped with a built-in printer and supports data output through RS232 and USB interfaces (optional).

 

Main Features

 

1) Equipped with Brinell, Rockwell, Vickers test methods;


2) 8 inch Touch-screen interface, easy to operate


3) Close loop, with high accuracy load cell, no need install weights;


4) Test force automatic correction, each file is automatically compensated force, improve the accuracy of the force a number of levels;


5) According to GB / ASTM hardness automatic conversion;


6) Rockwell automatically correct curvature radius;


7) Set a password to protect setup parameters, more samples and testing information;


8) Measuring U disk to save data to EXCEL format for easy editing and processing.


9) Modular design for easy maintenance.

Motorized X-Y Table Vickers Hardness Tester

 

Application Range
 

Determination of Brinell, Vickers, and Rockwell hardness for ferrous metals, non-ferrous metals, and hard alloys.

Brinell hardness testing for castings, annealed steel, normalized steel, non-ferrous metals, and soft alloys.

Rockwell hardness testing for quenched and tempered materials.

Vickers hardness testing for nitrided layers, ceramics, thin sheets, metal foils, plating layers, and tiny components.

 

Construction

 

The machine frame is designed to accommodate the high precision loading system. Specimen is clamped by vice or supported by proper fixtures. The test cycle is fully automatic. The accurate load is applied on a diamond indentor by means of dead weights. After a lapse of time, the load is removed automatically. The image id digitallized using a CCD Camera fitted on the machine and is captured by the PC. The diagonals of the indentation are measured by the PC and the Micro Hardness number is displayed directly on monitor.

Fully Automatic Testing Vickers Hardness Tester

Preparation: Ensure the surface of the material to be tested is clean and flat.


Selection of Test Load: Choose an appropriate test load based on the expected hardness of the material. For microhardness testing, this load is typically in the range of a few grams to a few kilograms.


Preparation of Indenter: Verify that the indenter (usually a diamond pyramid with a square base) is clean and in good condition.


Application of Load: Apply the chosen test load to the material's surface using the Vickers hardness tester. This is typically done by lowering the indenter onto the surface with a controlled force.


Indentation: Allow the indenter to dwell on the material's surface for a specified duration, usually a few seconds, to ensure proper indentation.


Measurement of Indentation: Use a microscope or optical system integrated into the Vickers hardness tester to measure the diagonal lengths of the indentation left by the indenter.


Calculation of Hardness: Calculate the Vickers hardness value using the formula: HV = 2×F​/d2, where HV is the Vickers hardness value, F is the applied load, and d is the average of the two diagonal lengths of the indentation.


Reporting: Record the test parameters, including the applied load, indentation dimensions, and calculated hardness value. Ensure compliance with relevant standards such as ISO 6507 or ASTM E384.
