These tipped pcbn inserts are made of pure cubic boron nitride and cannot be destroyed. These are thus widely used all over for machining hard metals like hardened steel and cast iron. In this situation it can perform superbly and it can also be used to increase self-done hot cuttings. When these inserts cut the hard metal for machining it produce an extreme temperature. So, they are pretty much durable and can last for a long time. They are also highly resistant to any chemical attacks.

It can easily cut the hard metals quite easily. There are a lot of benefits of these inserts. Advantage of tipped pcbn inserts is the lower cost than solid cbn inserts and solid corner pcbn inserts, tipped insert is one use only economical type, it requires a carrier like tungsten carbide base as substrate for the insert, and substrate have a pocket that will accommodate and support the tip, the working tips are brazed to tungsten carbide base, 1~4 tips depends on different insert shapes, this braze joint of tipped pcbn inserts represents the weak link not so good as solid cbn inserts and thoroughly brazed pcbn inserts, the maximum cutting depth is not more than 80% of the tip length. These are better and cheaper than that of the solid inserts and also offer a better surface finishing. These are highly beneficial and have different characteristics and advantages. These inserts are manufactured especially for different types of technologies and other advanced material processes. The tipped inserts are mainly used for the turning of the hard metals and also the most conventional option for machining.

advantages of lower cost and higher productivity make pcbn inserts with tipped cbn cutting edges are widely used for turing grey cast iron, nodular cast iron, ductile cast iron, hardened steel, high speed steel, bearing steel and ferrous alloys.

Compared with grinding, both technical and economic benefits can be achieved by pcbn inserts turning, performance of tipped cbn inserts are significantly better than that attainable with conventional tool materials. Tipped pcbn inserts could be used for rough to fine precision machining, continous to interrupted machining, to obtain a good surface finish. Home > Tipped PCBN insert > PCBN insert shape D
