PCBN inserts for turning cast iron and hardened steel

pcbn is the second hardest material in the world, and cbn related high precision cutting tools are introduced to industry, achieved high productivity and cost reductions. pcbn is the short name of polycrystalline cubic boron nitride, and pcbn inserts are mainly for the hard metal turning to replace the conventional machining way of grinding. We manufacture pcbn inserts for advanced material processes and technologies, with a set of knowledgeable employees and extensive manufacturing facilities, we are ready to serve the needs of our esteemed customers. Our highest selling products include solid cbn inserts, cbn cutting tools, cbn turning inserts, indexable cutting tool inserts, cnc cutting inserts, cbn machining inserts and cbn tooling inserts, just to name a few.

polycrystalline cubic boron nitride is an optimal material to cut ferrous metals, because pcbn is thermally stable up to approximately 1200℃ and has high resistance to chemical attack, so when pcbn inserts occur extreme temperatures for machining hard ferrous metals, it performed perfectly and can be used to promote self-induced hot cutting, so pcbn inserts are widely used for iron based alloy machining such as cast iron and hardened steel. We have three main types of cbn inserts in supply, they are solid cbn inserts, solid corner cbn inserts and tipped cbn inserts from continuous turning to heavy interrupted turning.

Solid CBN inserts, solid pcbn inserts for hard metal turning

Nowadays, the acceptance of using solid cbn inserts is becoming widespread all around the globe. As they are almost indestructible and made by purely cubic boron nitride, they possess a matchless capacity of heat absorption and you can use them at highest temperatures without any hassle. They are being utilized for multifarious purposes such as for turning hardened steel, nodular cast iron, grey cast iron, carbon steel, powdered metals, and work parts of automobile brake discs, aircraft jet engines, roller, bearing, pumps. The best part of solid cbn inserts is that the cost is minimized around 5 – 6 percent of the total machining cost. What’s more! The solid cbn inserts also provide the best in performance and hardness. With such a super high wear resistance, high processing precision, long service life, and affordable price, the solid cbn inserts are gradually grabbing the global marketplace.  

solid corner cbn inserts, Thoroughly brazed pcbn turning inserts

These methodically brazed inserts are solid-corner inserts, the insert blanks can be availed with pin-lock holes especially for clamping on toolbars or tool holders. Solid corner pcbn inserts have a base of tungsten carbide and cutting edges act as working tips. These are a sold alternate to cbn inserts used for hard-metal machining when clamping holes needed. They have the capability with superior solder ability as well as good resistance to the soldering heat. As a result, the impactful resistance of thoroughly brazed inserts is of high quality. They are generally used for interrupted machining. The double tips present in these inserts act as two working tips across both sides, thus increasing the overall efficiency. We have been consistently manufacturing the best quality cbn inserts for our clients.

Tipped pcbn turning inserts, polycrystalline cBN tipped inserts

CBN tipped inserts have gained competitive advantage due to their cost-effective pricing. We manufacture high quality cbn tipped inserts in accordance with the national as well as international standards. Cbn inserts help in improving the productivity of the machining process; ensuring that the life of the tool is optimum as well as enhancing the overall surface finishes for faster completion of work. Another advantage of these inserts is that they can be used from both sides. Thus, if one side is degraded or worn out, the customer can use the other.

These cbn inserts are generally applied for machining hardened steel and even a few steels with high alloy content. It is to be noted here that the aluminium alloys cannot be machined with cbn inserts because the aluminium builds up on the cutting edge instantaneously which triggers wear and poor surface finish in return, pcd inserts are more suitable for cutting these non-ferrous aluminum alloys.

The new advances in the designs of pcbn cutting tools have received overmuch accolades from across the globe due to both enhanced performance and its usage on a broad range of applications. You can use the pcbn to machine parts with a lower hardness but it is not recommended because they are mostly suggested to be applied to the work pieces with a 45 Rockwell C hardness rating. The pcbn inserts are very feasible and dependable for a broad range of roughing and finishing applications.
