Question 7

How do microhardness testers reflect the elastic and plastic deformation characteristics of materials?

Accepted Answer

The microhardness tester is an important mechanical property indicator that reflects the elastic and plastic deformation characteristics of materials.
During the testing process of our microhardness tester, a relatively hard square pyramid of standard shape and size is used to contact the material surface under a specific load force to determine the resistance of the material during the deformation process.
In this way, the ability of the material to resist plastic deformation, which is the elasticity of the material, can be understood; at the same time, the ability of the material to resist elastic deformation, namely the plasticity of the material, can also be understood.

Secondly, the test force of this machine does not need to be entered manually; the test force can be automatically read by simply rotating the load-changing handwheel device. In addition, the microhardness tester also features a dual-display function, using an LCD screen to simultaneously display two types of hardness results. Through the operation control keys, the hardness scales HV or HK can be selected while simultaneously setting multiple hardness conversion results such as HRA, HRB, HRC, and HB.

Question 10

What safety protection measures are in place during the operation of Zhongze Companys metallographic mounting machine?

Accepted Answer

During the operation of our company's metallographic mounting press, first, when the set time is reached, the timer will emit a signal and the temperature controller will automatically cut off the power to prevent potential hazards from overheating. Secondly, the equipment will automatically cool for 3 to 5 minutes (adjustable) to ensure operational safety. Finally, after the lower mold automatically descends to the bottom, it is necessary to rotate the upper mold base so that the upper mold leaves the mold tube; this can avoid injury to the hands during the sampling process and ensure the safety of the operator.

Question 11

What are the suitable applications for a microhardness tester?

Accepted Answer

Microhardness testers are widely used in research in fields such as materials science, physics, chemistry, and medicine.
It is suitable for studying the microscopic structures and hardness characteristics of materials such as metals, alloys, ceramics, glass, and plastics.

Question 12

Why does the automatic precision metallographic specimen mounting press need a dust cover when not in use for a long time?

Accepted Answer

When the fully automatic precision metallographic specimen mounting press is not in use for a long time, it should be covered with a lint-free dust cover. This is to prevent the formation of background stray light caused by dust and residual fibers. Maintaining the cleanliness and hygiene of the equipment is crucial to its performance and lifespan, which is also a firm commitment to product quality and customer satisfaction from us at Nakazawa Testing Equipment Co., Ltd.

Question 13

How to maintain a metallographic mounting machine in daily use to ensure its smooth operation?
