Hardness is generally defined as its ability to resist deformation. The hardness in science is defined by the energy density (energy per unit volume) required to generate material strain. There are many methods, standards and classifications for measuring Hardness. Let's briefly explain them.

Mohs scale is a very simple hardness measurement and classification method widely known. In this standard, Hardness is measured through scratch test of friction between materials. All materials are arranged according to 10 grades, and each grade is calibrated with a standard mineral. The hardness levels of these minerals in the table below range from soft to hard.

Diamond is a very hard material known to humans, and it can penetrate almost any material. When using diamond metallographic cutting blades to cut brittle or soft material samples such as granite and ceramics, there was no phenomenon of diamond particle fragmentation or a large number of diamond particle detachment. However, when using it to cut very hard and dense materials such as hard alloys and tungsten carbide, it is necessary to increase the contact pressure of each diamond particle to enable the diamond to penetrate the material being cut, thus achieving the goal of fast and intact sample cutting.

The hardness, density, and brittleness of the material being cut will determine the type of diamond metallographic cutting blade to be selected, and whether the diamond in the diamond bonding matrix needs to have sufficient toughness and hardness to rupture the material through strength; Or whether the diamond in the diamond bonding matrix needs to be fragile and flexible, penetrating the material with sharp points, etc.

QMAXIS, based on its in-depth research on intelligent cutting technology, produces various types of diamond metallographic cutting blades that exhibit outstanding performance characteristics when cutting hard and brittle materials, as well as soft and fragile materials. Compared to traditional metallographic cutting blades, they are more effortless and effortless.

Under the condition of sufficient equipment and technical conditions, if you want to cut the metallographic samples quickly and in good condition, it is a prerequisite to select the right cutting piece. It is the hard truth to select the correct type of diamond metallographic cutting piece according to the Hardness!
