What is a desktop Rockwell hardness testing machine?
Hardness testing is a vital technology in the fields of industrial production, materials research and quality control. As a common hardness testing equipment, the desktop Rockwell hardness testing machine is widely used in hardness measurement of metals, plastics, ceramics and other materials. This article will introduce in detail the definition, working principle, application fields of desktop Rockwell hardness testing machine, as well as hot topics and hot content in the past 10 days.
1. Definition of desktop Rockwell hardness testing machine
The desktop Rockwell hardness testing machine is a precision instrument used to measure the hardness of materials, using the Rockwell hardness testing principle. It presses the indenter into the material surface under specific conditions and measures the depth or diameter of the indentation to calculate the hardness value of the material. The desktop design makes it suitable for use in laboratories and production lines, with the characteristics of easy operation and high measurement accuracy.
2. Working principle of desktop Rockwell hardness testing machine
The working principle of the desktop Rockwell hardness testing machine is based on the Rockwell hardness testing method, which mainly includes the following steps:
| steps | Description |
|---|---|
| 1. Preloading | Apply a small initial load (usually 10 kgf) to bring the indenter into contact with the material surface. |
| 2. Main loading | Increase the main load (depending on the test scale, the load range is 60-150 kgf), and the indenter presses into the material surface. |
| 3. Uninstall | The main load is removed, the preload is retained, and the depth or diameter of the indentation is measured. |
| 4. Calculate hardness value | Based on the depth or diameter of the indentation, the Rockwell hardness value (HR) is calculated by the formula. |
3. Application fields of desktop Rockwell hardness testing machine
Desktop Rockwell hardness testing machines are widely used in the following fields:
| field | Application examples |
|---|---|
| metal processing | Test the hardness of steel, aluminum alloy, copper alloy and other metal materials. |
| Plastic industry | Measure the hardness of plastic products and evaluate their wear resistance and strength. |
| ceramic material | Test the hardness of ceramic products to ensure they meet industry standards. |
| Quality control | Products are tested for hardness on the production line to ensure quality consistency. |
