PCBN standard inserts

【PCBN material characteristics】

Polycrystalline cubic boron nitride PCBN is made of cubic boron nitride CBN particles as the main component, adding metal or ceramics as a binder, and sintered under high temperature and high pressure. Compared with carbide tool material, it has higher strength and red hardness, better heat resistance and wear resistance. Due to these characteristics, PCBN inserts is not only used to machining cast iron, but also can realize long-life machining. In the past, hard to cut materials such as hardened steel, rollers, high-speed steel and heat-resistant carbide that have been grinded have been relied on to obtain ideal machining accuracy and production efficiency.

Polycrystalline cubic boron nitride (PCBN) is made by sintering CBN powder and bond. Because of its low affinity with ferrous metals, it is mainly used for cutting ferrous metals.

According to its organization, it can be classified as follows:

▪KB55, KB10 andKB95T are directly sintered from CBN particles with high CBN content and good wear resistance. They are suitable for processing high hardness materials such as cast iron, heat-resistant alloy and cemented carbide.

▪ KB30, KB21, KB61 and KB50 are composed of CBN particles and ceramic binder, which increases the binding force between CBN particles and can effectively inhibit the collapse problem of strong intermittent cutting. They can be used to process quenched steel and other materials, giving play to their excellent wear resistance and strong toughness.

Advantages of PCBN inserts in cutting hardened steel.

Cost: Replacing grinding with turning can reduce the investment in purchasing new machine tools and equipment.

Manpower: It can reduce labor costs.

Quality: One clamping can finish the finishing of complex surfaces, so as to improve the machining accuracy of workpieces.

Environmental protection: Dry cutting is conducive to protecting the earth's environment and realizing green machining.

PCD/PCBN standard inserts have the following advantages over ordinary integral welding tools:

Convenient loading and unloading, fast and accurate positioning, saving tool change time.

Extremely high wear resistance greatly extends the service life of the tool.

High speed, high efficiency and high precision machining can be realized.

Easy to manage, convenient and safe logistics.
