Product Introduction
 
Metal and Plastic Rockwell 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).

Test Procedure of Rockwell Hardness Tester
 
Automatic Testing Process Rockwell Durometer

Preparation

  • Ensure the Rockwell hardness tester is properly calibrated according to the manufacturer's instructions.
  • Select the appropriate Rockwell scale based on the material and hardness range being tested.
  • Choose the appropriate indenter and test force for the selected scale.


Sample Preparation

  • Prepare the surface of the sample by grinding or polishing to remove any irregularities or surface contaminants.
  • Ensure the sample surface is clean and free from any debris or oil that could affect the test results.


Test Setup

  • Place the sample on the anvil or support table of the Rockwell hardness tester.
  • Lower the indenter onto the sample surface using the manual or motorized loading mechanism.
  • Apply the initial preload force to ensure proper contact between the indenter and the sample.


Test Execution

  • Apply the full test force specified for the selected Rockwell scale by activating the tester.
  • Maintain the test force for the specified dwell time to allow for sufficient indentation to occur.
  • Release the test force and allow the indenter to retract from the sample surface.

Measurement

  • Measure the depth of penetration (indentation) using the built-in depth-measuring device.
  • Record the depth of penetration to the nearest unit specified by the standard (typically in tenths or hundredths of a millimeter).


Calculation

  • Calculate the Rockwell hardness number using the formula specified for the selected Rockwell scale.
  • The hardness number is typically expressed as a combination of a scale letter and a numerical value (e.g., HRC 55).


Reporting

  • Document the test results, including the Rockwell hardness number, scale used, test force, dwell time, and any relevant details about the sample.
  • Ensure the test report complies with any applicable standards or quality control requirements.


Post-Test

  • Clean the sample and remove any residual indenter marks.
  • Review and verify the test results for accuracy and consistency.
  • If necessary, perform additional tests or adjustments to ensure the reliability of the hardness measurements.
