In the production of hardware parts, hardness is a crucial indicator. Take the part shown in the figure as an example. We can use a Rockwell hardness tester to conduct hardness testing.
Our electronic force-applying digital display Rockwell hardness tester is a highly practical tool for this purpose. The testing process of this hardness tester is extremely simple and intuitive.
It applies a force of 150kgf and uses a diamond indenter for the test. After the test is completed, the measured hardness value is based on the HRC Rockwell hardness scale. This method of using the Rockwell hardness tester has been widely recognized and applied in the industry for its accuracy and convenience. It enables manufacturers to accurately measure the hardness of hardware parts, ensuring that the products meet the required quality standards. Whether it is in the production of mechanical components, construction hardware, or other related fields, the accurate detection of hardness is essential for ensuring the performance and service life of the products.
Our hardness tester not only provides reliable testing results but also simplifies the testing operation process, which greatly improves the efficiency of quality control in the production process of hardware parts.
Here are the detailed test steps for using the electronic force-applying digital display Rockwell hardness tester of Shandong Shancai Company to measure the hardness of hardware standard parts according to the Rockwell hardness testing method for metallic materials:
- Prepare the tester and specimen:
1.1Ensure that the electronic force-applying digital display Rockwell hardness tester is properly calibrated and in good working condition. Check all the connections and functions, such as the power supply, digital display, and force application system.
1.2 Select the hardware standard part specimen to be tested. Make sure the surface of the specimen is clean, free of any dirt, oil, or oxide layers. If necessary, polish the surface to obtain a smooth and flat testing area.
2. Install the indenter: Select the appropriate diamond indenter according to the testing requirements. For measuring the hardness on the HRC Rockwell hardness scale, install the diamond indenter into the tester’s indenter holder. Ensure that the indenter is firmly fixed and properly aligned.
3. Set the test force:Adjust the tester to set the test force to 150kgf. This is the standard test force for the HRC scale. Confirm that the force setting is accurate through the tester’s control panel or relevant adjustment mechanism.
4. Position the specimen: Place the specimen on the tester’s anvil. Use appropriate fixtures or positioning devices to ensure that the specimen is firmly and stably positioned, and the testing surface is perpendicular to the indenter’s axis.
5.Hardness tester automatically loading, dwell, unloading
6.Read the hardness value:Once the indenter is completely removed, the tester’s digital display will show the measured hardness value on the HRC Rockwell hardness scale. Record this value accurately.
7. Repeat the test (if necessary): For more accurate results, it is recommended to repeat the above steps at different positions on the specimen’s surface and calculate the average value of multiple measurements. This helps to reduce the error caused by uneven material properties on the specimen’s surface.
By following these steps carefully, you can accurately measure the hardness of hardware standard parts using the Rockwell hardness testing method with the electronic force-applying digital display Rockwell hardness tester.
