There are many advantages of the tipped pcbn inserts for hard metals turning. Some of the significant ones are listed below:
· They are much more affordable and are available in lower cost than that of the solid cbn inserts, only the cutting edge of the insert is made by pcbn, the working tips brazed on the tungsten carbide substrate low down the insert price. That is why it is preferred more in the industrial uses as it can save money and reduce the production cost.
· It is only for one use in economical type. It eliminates the chances of regrinding. When the pcbn cutting edge is blunt and end up with its lifetime, just replace with new tipped inserts, then start with the new processing without break.
· The performance of the tipped inserts is way better than any other with usual materials. This performance is quite significant and great which makes it preferable and advantageous. Pcbn inserts are much better than tungsten carbide inserts and ceramic inserts, even coated or without coated, they perform a super fine surface finishing and has great wear resistance, heat resistance and impact resistance.
· It can be used in the fine or even for super fine quality machining to get a fine finished surface, G grade inserts allow less tolerance and reach better surface finishing, that is why industries dealing with delicate and super fine quality materials also prefer to use theses tipped cbn inserts.
· These inserts are found in lower cost but have higher productivity which make these highly advantageous for the people to get them easily as well as in low price and can used widely for nodular cast iron, high speed steel, turning grey cast iron and for many other purposes.
