PCBN tool is an artificial cubic boron nitride tool, in high temperature can also maintain high hardness characteristics, mainly for the processing of iron.CBN(Cubic Boron Nitride) was first synthesized by us general electric (GE) under high temperature and high pressure by the manual method in the 1950s. Its hardness is second only to diamond but far higher than other materials, so it is collectively referred to as superhard materials with diamond.
Ciri Alat Pisau PCBN
Berdasarkan perbedaan komposisi yang ditambahkan, PCBN dibagi menjadi dua jenis PCBN yakni CBN single-chip langsung dengan cara membakar simpul-simpul langsung dan tertentu prosentase pembakaran PCBN. Berdasarkan kaedah persiapan bahan komposit: blok pembakaran PCBN dibagi menjadi satu blok PCBN secara keseluruhan dan kompos componit PCBN dengan paduan yang keras. Komposit PCBN yang berlendir secara luas diterapkan oleh tablet componit PCBN yang bertekstur lengket. Kekerasan PCBN berbeda-beda dengan proporsi penambahan tempel. Semakin tinggi kadar tempel, semakin rendah tingkat kekerasannya, semakin baik kelenturan. Beragam jenis tempel, penggunaan PCBN berbeda.
CBN is widely used in grinding because of its high hardness, chemical inertia and thermal stability under high temperature. Because the CBN has better than the other characteristics of the cutting tool material, so people began trying to apply to machine, but smaller particles of monocrystalline CBN, it is difficult to make knives, and CBN sintering property is very poor, difficult to make a larger CBN sintered body, until the 1970 s, the former soviet union, China, United States, Britain, and other countries have been developed as a cutting tool of CBN sintered body, Polycrystalline Cubic Boron Nitride PCBN (Polycrystalline Cubic Boron Nitride). Since then, PCBN has been applied in various fields of cutting with its superior cutting performance, especially in the cutting of high hardness materials and difficult materials. After more than 30 years of development and application, PCBN tool materials for processing different materials have emerged.
