Metallographic precision cutting cannot be separated from diamond cutting blades. However, in addition to hardness indicators, diamond cutting blades also have different diamond concentrations. There are significant differences in the performance and application of low and high concentration diamond cutting blades. Have you chosen the right one?

The proportion and distribution of diamond particles, also known as concentration, directly affect the overall cutting performance and price of diamond blades. Diamond concentration refers to the content of diamond in the cutting edge of a diamond cutting blade. Diamond concentration is usually defined as: concentration 100=4.4 carats per centimeter layer volume (particles+matrix). Based on this definition, assuming a diamond density of 3.52 g/cm3 and 1 carat=0.2g, the concentration is 100, indicating that the diamond ratio is 25% of the volume of the diamond layer. The diamond concentration range in a standard diamond cutting blade is 0.5 carat/cm3 to 6 carat/cm3, which means that the diamond concentration ranges from 8 to 135.


Choosing a cutting blade with an appropriate diamond concentration is crucial for fully utilizing the cutting ability of precision cutting machines. Choosing a cutting blade with an appropriate diamond concentration also depends on factors such as the material being cut, the type and hardness of the substrate, diamond particle size, cutting speed, and the cooling lubricant used.


In addition, diamond concentration is also an important factor affecting the lifespan and cutting speed of diamond cutting discs. It is recommended to use cutting blades with higher diamond concentrations to cut softer wear-resistant materials such as polymer rubber and plastic, but this will greatly reduce cutting speed. It is recommended to use cutting blades with lower diamond concentrations to cut hard and brittle materials such as ceramics and glass.

QMAXIS, with its rich experience and unique intelligent cutting technology, balances diamond concentration and other factors to help users choose the appropriate diamond metallographic cutting blade to meet their specific applications.

Nowadays, most production and research institutions use low concentration diamond cutting blades to cut ceramics, glass, silicon, carbides, sapphires, and other related semiconductor and optical materials; Use high concentration diamond cutting blades to cut metals, such as stainless steel, aluminum, titanium, PCB circuit boards, etc. The QMAXIS program in the United States is called; Intelligent cutting; The new technological breakthroughs are fundamentally changing these traditional concepts and setting new standards for measuring the performance of diamond cutting blades. Intelligent cutting technology effectively positions diamond particles within the metal matrix, enabling each diamond to better participate in cutting activities and actively play a cutting role.


Based on the above introduction, have you chosen the right diamond cutting blade with different concentrations?
