The general definition of material hardness refers to its ability to resist deformation. Scientific hardness is defined by the specific energy (kinetic energy of the enterprise volume) required to cause the strain force of the material. There are many ways, specifications and classifications to accurately measure the hardness of materials, so let's briefly explain them. Mohs hardness is a widely spread and relatively simple method for precise hardness measurement and classification. In this type of specification, the hardness of the material is accurately measured according to the scratch test of the middle friction of the material. All materials are sorted by 10 levels, and each level is calibrated with a standard mineral. The hardness levels of the minerals listed below range from soft to hard.

Diamond is a very hard material that people already know. It can basically penetrate all materials. When the diamond metallographic cutting blade is used to cut granite, porcelain and other ductile or soft materials such as copper, it does not mainly show that the diamond particles are broken or a lot of diamond particles fall off. However, if you use it to cut very hard, high-density materials such as cemented carbide tools and cobalt alloys, you must increase the contact stress of each diamond particle so that the diamond can penetrate the material to be cut, and then achieve rapid and complete The purpose of non-destructively cutting off the test piece. The hardness, relative density and ductility of the material to be cut will determine which diamond metallographic cutting discs to choose. Whether the diamond in the diamond-bonded cultivation substrate must have sufficient ductility and hardness to crack the material according to the super strength; or Does the diamond in the diamond-bonded cultivation substrate have to be fragile and flexible, and penetrate the material with sharp points? With its in-depth analysis of intelligent cutting technology, the various types of diamond metallographic cutting blades made, when cutting hard and ductile materials, and various materials such as soft and easy to break, they mainly show outstanding performance. Compared with traditional metallographic cutting discs, it is more comfortable and handy.

Under the condition of sufficient equipment and technical standards, if you want to cut metallographic specimens quickly and intact, the correct selection of the cutting disc is a prerequisite. The key is to select the appropriate type of diamond metallographic cutting disc according to the hardness of the material!
