7° back angle diamond blade: How to become an all-round player in the field of cutting?

The reason why the 7° back angle diamond blade can perform well in the cutting of various materials is first of all due to the high-quality basic materials it uses. These materials are carefully selected to ensure that they have high strength, high hardness, good wear resistance and toughness, laying a solid foundation for the excellent cutting performance of the blade.

High-speed steel has become one of the traditional materials for manufacturing cutting tools with its excellent hot hardness and wear resistance. In the 7° back angle diamond blade, high-speed steel is widely used to process materials with moderate hardness and complex cutting conditions. The high hardness of high-speed steel enables it to keep the edge sharp during the cutting process, while its good toughness enables it to withstand large cutting forces and impact forces, and it is not easy to break or fracture.

Cemented carbide is a composite material made of hard particles such as carbides, nitrides, borides and binders of refractory metals through powder metallurgy. In the 7° back angle diamond blade, cemented carbide has become an ideal choice for processing steels with higher hardness (such as alloy steel, tool steel, etc.) due to its extremely high hardness and good wear resistance. The hardness of cemented carbide is much higher than that of high-speed steel, which can effectively resist the wear and adhesion of materials during the cutting process and extend the service life of the tool.

Ceramic materials are widely used in positive 7°rear angle rhombic inserts due to their ultra-high hardness and excellent high temperature resistance. Especially when processing high-hardness and high-toughness materials (such as stainless steel, titanium alloy, etc.), ceramic blades can show better cutting performance. The hardness of ceramic materials is close to that of diamonds, which can effectively reduce the friction and heat accumulation of materials during cutting, reduce cutting forces and cutting temperatures, and improve cutting efficiency and tool life.

In addition to high-quality basic materials, positive 7°rear angle rhombic inserts also use advanced coating technology to further improve their cutting performance and durability. Coating technology changes the physical and chemical properties of the blade surface by forming one or more layers of thin films with specific properties on the blade surface, thereby improving its cutting efficiency, reducing wear and extending its service life.

In positive 7° clearance angle diamond blades, commonly used coating materials include titanium nitride (TiN), aluminum titanium nitride (AlTiN), aluminum oxide (Al₂O₃), etc. These coating materials have excellent hardness, wear resistance, oxidation resistance and lubricity, and can effectively reduce friction and heat accumulation during cutting, reduce cutting force and cutting temperature, and improve cutting efficiency and tool life.

Titanium nitride (TiN): It has a golden appearance and good wear resistance, and is suitable for processing materials with moderate hardness.
Aluminum titanium nitride (AlTiN): It has higher hardness and better oxidation resistance, and is suitable for processing steel and stainless steel with higher hardness.
Aluminum oxide (Al₂O₃): It has extremely high hardness and excellent high temperature resistance, and is suitable for processing high hardness and high toughness materials.

In the coating process of the positive 7° back angle diamond blade, a variety of advanced process technologies and equipment are used, such as physical vapor deposition (PVD), chemical vapor deposition (CVD), etc. These process technologies can accurately control the composition, structure and thickness of the coating material, thereby optimizing the performance of the coating. At the same time, through innovative coating designs, such as multi-layer coatings, gradient coatings, etc., the wear resistance, oxidation resistance and lubricity of the coating can be further improved to meet the cutting requirements under different processing conditions.

Due to the use of high-quality basic materials and advanced coating technology, the positive 7° back angle diamond blade can be used for cutting various materials. Whether it is a steel with higher hardness (such as alloy steel, tool steel, etc.) or a stainless steel with higher toughness, this blade can perform well and meet different processing needs.

When processing steel with higher hardness, the carbide or ceramic matrix of the positive 7° back angle diamond blade can provide sufficient hardness and wear resistance to ensure the stability and efficiency of the cutting process. At the same time, the coating technology can further reduce the friction and heat accumulation during the cutting process, reduce the cutting force and cutting temperature, and improve the cutting efficiency and tool life.

When processing stainless steel with higher toughness, the tough base material (such as high-speed steel) and coating technology of the positive 7° back angle diamond blade can work together. The high toughness of high-speed steel enables it to withstand greater cutting force and impact force, and it is not easy to break or fracture. The coating technology can reduce the friction and heat accumulation during the cutting process, reduce the cutting force and cutting temperature, and improve the cutting efficiency and tool life. At the same time, the lubricity of the coating material can also reduce the adhesion and chip accumulation during the cutting process, further improving the cutting quality.

The excellent cutting performance and wide applicability of the positive 7° back angle diamond blade not only improves processing efficiency, reduces production costs, but also improves the quality of the final product. During the cutting process, the blade can maintain a low cutting force and cutting temperature, reducing energy consumption and heat accumulation during the cutting process, thereby extending the service life of the machine tool and reducing maintenance costs.

Due to the high durability of the blade, the frequency of tool replacement and downtime are reduced, and the continuity and stability of the production line are improved. This not only improves production efficiency, but also reduces production costs, creating greater economic benefits for the company. The high-quality base material and advanced coating technology of the positive 7° back angle diamond blade can also reduce tool wear and chipping during the cutting process, reduce scrap rate and rework rate, and further improve production efficiency and product quality.
