Cubic Boron Nitride (CBN) inserts are advanced cutting tools used in metalworking, and they offer several key benefits that make them highly valuable for specific machining applications. CBN is a synthetic material with hardness second only to diamond, and it exhibits exceptional properties when used as a cutting tool material. Here are some of the main benefits of CBN inserts:
Hardness and Wear Resistance:
CBN inserts are extremely hard, surpassing the hardness of traditional cutting tool materials like carbide inserts. This hardness allows CBN to retain sharp cutting edges for prolonged periods, even when machining hardened steels and superalloys. As a result, CBN inserts offer superior wear resistance and extended tool life, reducing the frequency of tool changes and improving overall productivity.
High Temperature Resistance:
CBN is highly resistant to thermal degradation, enabling it to withstand the intense heat generated during high-speed machining operations. This makes CBN inserts ideal for cutting applications involving tough and hard-to-machine materials that generate significant heat during machining.
Compatibility with Hardened Materials:
CBN inserts are particularly well-suited for machining hardened steels and cast irons. They can efficiently remove material at high cutting speeds, resulting in faster machining times and improved surface finish on hardened workpieces.
Improved Surface Finish:
The exceptional cutting properties of CBN inserts contribute to achieving smooth and precise surface finishes on machined components. This benefit is especially crucial in applications where surface quality is critical.
Reduced Cutting Forces:
CBN inserts have a low coefficient of friction, leading to reduced cutting forces during machining. This feature allows for more stable and predictable cutting performance, resulting in better accuracy and dimensional consistency in the machined parts.
High Chemical Stability:
CBN is chemically inert, meaning it has low chemical reactivity with most workpiece materials. This property minimizes the risk of workpiece-material adhesion to the cutting tool during machining, reducing built-up edge formation and workpiece contamination.
Versatility:
CBN Insert Price are versatile tools used in various metalworking applications, including turning, milling, boring, and grinding. They are particularly effective in machining materials that are challenging for conventional cutting tools.
Green Machining:
CBN insert require less coolant/lubrication during machining compared to some other cutting tools, which can lead to reduced environmental impact and lower operating costs.
Despite their numerous benefits, CBN insert for machine also have some limitations. They are relatively expensive compared to traditional cutting tool materials, and their brittleness may make them unsuitable for certain applications with high levels of shock and impact forces. As with any cutting tool, proper tool selection, cutting tools parameters, and coolant/lubrication application are essential to achieve the best results and extend the life of CBN insert India.
