Question 4

What are the unique features of a microhardness tester compared to other hardness testing methods?

Accepted Answer

The obvious advantage of the microhardness tester is that its hardness value is independent of the magnitude of the test force; as long as the material hardness is uniform, the test force can be chosen arbitrarily, and the hardness value will remain constant. This provides users with a unified scale across a wide range of hardness, making testing more convenient and accurate.
In addition, for materials with medium to low hardness values, the test results of the microhardness tester are almost identical to those of the Brinell hardness tester, but when testing hardness less than 400HV, the microhardness tester can even provide test results that are closer to the true value.

Question 5

What are the advantages of microhardness testers when testing thin and small materials?

Accepted Answer

The microhardness tester demonstrates incomparable advantages when testing thin and small materials. Its test force can be as small as 10gF, so the indentation is very tiny, making it particularly suitable for testing thin or small materials. This characteristic makes the application of the microhardness tester particularly prominent in fields such as microelectronics and precision machinery, meeting the high requirements for precision and non-destructiveness in material hardness testing in these fields.

Question 6

How to select the appropriate test force when operating a microhardness tester from Zhongze Company?

Accepted Answer

When selecting the test force, our company's microhardness tester first requires the user to turn on the power of the hardness tester, and then rotate the test force change handwheel to select the appropriate test force. Our microhardness tester provides a variety of test forces for users to choose from to meet the hardness testing needs of different materials.

Question 12

What special designs are included in Rockwell hardness testers to protect the equipment and ensure the validity of the test?

Accepted Answer

Chung-Tse's Rockwell hardness tester takes into account the protection of the equipment and the effectiveness of the testing in its design. For example, our equipment is equipped with a screw protection sleeve. When the hardness tester is not in use or the height of the test piece is less than 100mm, it can be placed over the outside of the screw to prevent the impact of dust on the equipment. When the height of the test piece is greater than 100mm, it must be removed to avoid pushing up the working platform, which would lead to an invalid test. This design ensures the long-term use of the equipment and the accuracy of the tests.

Question 13

Could you please explain in detail the working principle and advantages of the Rockwell hardness tester?

Accepted Answer

Of course. The Rockwell hardness tester is a high-quality product represented by our company, Chung-Tse, and it adopts a unique indentation measurement principle. Under a certain static load, a diamond indenter is pressed vertically into the sample surface, and the hardness value is obtained by measuring the depth of the indentation. This method is particularly accurate for measuring high-hardness materials such as engineering ceramics.
Compared with Brinell hardness testers, the indenter deformation of the Rockwell hardness tester is smaller when measuring high-hardness materials, and the measurement results are more accurate. In addition, our Rockwell hardness tester is easy to operate and has high measurement efficiency, making it your ideal hardness measurement tool.

Question 14

What is the importance of the continuous stability of the mechanical properties of a metallographic mounting machine in practical use?

Accepted Answer

For metallographic mounting presses, the continuous stability of mechanical performance has an importance that cannot be ignored in actual use. A metallographic mounting press with stable mechanical performance can not only maintain an optimal working state during long-term use, ensuring the consistency and stability of imaging quality, but also effectively extend the service life of the equipment and reduce the frequency of maintenance and replacement, thereby saving customers a significant amount of time and economic costs. Therefore, when choosing a metallographic mounting press, in addition to focusing on imaging quality, it is also necessary to emphasize the continuous stability of its mechanical performance, so as to ensure that the equipment always maintains good performance and efficiency during long-term use.

Question 15

Why is the temperature of the metallographic mounting machine set at 130~150 ℃?

Accepted Answer

The temperature of the metallographic mounting machine is set at 130 ~ 140°C, because within this temperature range, thermosetting plastics can achieve the optimal pressing effect. Too low a temperature may lead to incomplete curing of the plastic, while too high a temperature may cause the plastic to decompose or discolor, affecting the quality of the sample. Therefore, we recommend that users set the temperature of the metallographic mounting machine at 130 ~ 150°C to ensure the stability and reliability of the mounting effect.

Question 16

What safety precautions should be taken when operating a metallographic mounting machine?

Accepted Answer

When operating the metallographic mounting machine, safety is the first priority. First, ensure the power connection is stable to avoid electrical faults. Secondly, when cleaning the mounting material from the edges of the upper and lower modules, you can use your fingernails to scrape it off to prevent scratching the modules. In addition, when the temperature of the mounting machine rises to the set value, be especially careful of burns and ensure that operations are carried out within the appropriate temperature range. Following these safety guidelines can ensure that the operation process is smooth and safe.

Question 17

What is the importance of temperature control during the metallographic mounting process?

Accepted Answer

Temperature control is crucial for the operation of the metallographic mounting machine. During the mounting process, an appropriate temperature can ensure the fluidity and viscosity of the mounting material, thereby obtaining high-quality mounted samples.
Taking bakelite powder (phenolic molding plastic) as an example, its ideal mounting temperature is usually between 130 ~ 150°C. Within this temperature range, bakelite powder can fully melt and evenly fill into the gaps of the sample, ensuring the accuracy and reliability of the mounting results. Therefore, correctly setting and controlling the temperature is an important step that cannot be ignored when using the metallographic mounting machine.

Question 18
