A20 Golden Tae CBN Abrasive paura mo Metal Bond Vitrified Tono Tono
A20 Tae Koura Putapa Boron Nitride Abrasive Paura Mo te Resin Bond Tono
1. Cubic Boron Nitride Introduction
Ko te CBN (cubic boron nitride) superabrasive he nui te pakeke me te teitei o te pāmahana parenga, e wha nga wa o te abrasive tuku iho i roto i te mau kakahu, me te kaha o te werawera.Kei te whakamahia nuitia a CBN ki te huri i te maakete whakangao, mai i te aerospace superalloys me te whakamaarama waiariki ki te rino whakapakeke i roto i te kawe motuka me te umanga taputapu hei whakapai ake i te pai me te whiwhi i te waa tukatuka poto rawa atu.
CBN-A20, te tae koura, te monocrystal maramara me te ahua rite tonu me te tino uaua.He pai te ahua o te tetrahedron tapahi me te koi koki whaiaro.He pai mo nga taputapu here vitrified me nga taputapu here whakarewa, huri wira, ka taea hoki te whakamahi mo nga taputapu hiko mo te tukatuka i te whakarewa ferrous me te koranu.
