Automatic Rockwell Superficial Hardness Tester

An Automatic Rockwell Superficial Hardness Tester is a specialized instrument used to measure the hardness of materials, particularly thin or small samples. It is an advanced version of the regular Rockwell Hardness Tester, specifically designed for testing materials with low loads and shallow indentations. The automatic feature eliminates manual load application and measurement, ensuring accurate and repeatable results. It is commonly used in industries such as metalworking, automotive, and aerospace, where precise hardness measurements of thin materials are crucial for quality control and material characterization.

Types of Automatic Rockwell Superficial Hardness Tester

KHT900-A Automatic Rockwell Superficial Hardness Tester

The KHT900-A combines the functionalities of Regular Rockwell and Rockwell Superficial hardness testing for both metal and plastic materials. Its innovative and robust design ensures accurate results and simplifies the installation process.

KHT900-M Automatic Rockwell Superficial Hardness Tester

The KHT900-M combines the functionalities of Regular Rockwell and Rockwell Superficial hardness tests, making it appropriate for assessing both metal and plastic materials. It is equipped with a manual handle wheel for initial load application, which is seamlessly followed by an automated process for applying the main load and conducting the test cycle.

What Is The Testing Procedure For An Automatic Rockwell Superficial Hardness Tester?

Preparation

The sample is prepared by ensuring a clean and flat surface for testing. The Automatic Rockwell Superficial Hardness Tester is set up with the appropriate indenter and test load for the material being tested.

Load Application

The tester applies a minor load to the sample, followed by the major load. The minor load establishes the zero position, and the major load creates the indentation on the surface of the material.

Measurement

The depth of penetration is measured automatically by the tester, providing the hardness value on the Superficial Rockwell scale. The result is displayed on the instrument’s screen or can be recorded digitally for further analysis. The tester may also have the capability to calculate and display hardness values in other scales, such as Brinell or Vickers.

What Is The Maintenance Required For An Automatic Rockwell Superficial Hardness Tester?

To ensure the proper functioning and accuracy of an Automatic Rockwell Superficial Hardness Tester, regular maintenance is necessary. Here are some maintenance tasks typically required:

Cleaning: Regularly clean the tester to remove any debris, dust, or contaminants that may affect its performance. Use a soft cloth or brush to clean the surfaces and avoid using abrasive materials.

Lubrication: Apply lubrication to moving parts as recommended by the manufacturer to prevent friction and ensure smooth operation.

Calibration: Periodically calibrate the tester to maintain accuracy. This may involve adjusting the load application system, verifying the accuracy of the indenter, and checking the measurement system against certified reference standards.

Inspection: Regularly inspect the tester for any signs of wear, damage, or misalignment. Address any issues promptly to prevent further damage and maintain accurate results.

Follow Manufacturer Guidelines: Follow the specific maintenance guidelines provided by the manufacturer to ensure proper care and longevity of the Automatic Rockwell Superficial Hardness Tester.
