tipped PCBN turning insert

shape W hexagon shape (80 degree)

tipped pcbn inserts could be used for rough to fine precision machining, continous to interrupted machining, to obtain a good surface finish. 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. 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.

The tipped inserts are mainly used for the turning of the hard metals and also the most conventional option for machining. These inserts are manufactured especially for different types of technologies and other advanced material processes. These are highly beneficial and have different characteristics and advantages. These are better and cheaper than that of the solid inserts and also offer a better surface finishing. 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.

There are a lot of benefits of these inserts. It can easily cut the hard metals quite easily. They are also highly resistant to any chemical attacks. So, they are pretty much durable and can last for a long time. When these inserts cut the hard metal for machining it produce an extreme temperature. In this situation it can perform superbly and it can also be used to increase self-done hot cuttings. These are thus widely used all over for machining hard metals like hardened steel and cast iron.

These tipped inserts are made of pure cubic boron nitride and cannot be destroyed. It has an extreme capacity to absorb heat and thus using them even at highest temperature will not create any problem. It provides the best performance and offer hardness too. It also has a high wear resistant power with a long service life. They are also available in affordable prices and thus industries do not have to spend a lot over these inserts. It has a superior processing precision and with all these qualities and benefits, these inserts are grabbing a great position in market place worldwide.

pcbn adds to the toughness of the tool and makes it more durable and sturdy, and helps to improve the surface quality and reduce the scrap rates. It also ensures a tight clamping which is ideal for the any heave duty machining applications.
