A20 Golden Xim CBN Abrasive Powder Rau Hlau Bond Vitrified Bond Daim Ntawv Thov
A20 Golden Xim Cubic Boron Nitride Abrasive Hmoov Rau Resin Bond Daim Ntawv Thov
1. Cubic Boron Nitride Taw Qhia
CBN (cubic boron nitride) superabrasive yog muaj zog hardness thiab kub tsis kam, plaub npaug ntawm cov tsoos abrasive nyob rau hauv hnav tsis kam, thiab muaj txawv thermal conductivity.CBN yog dav siv nyob rau hauv kev sib tsoo kev lag luam, los ntawm aerospace superalloys thiab thermal spraying mus rau hardened steel nyob rau hauv automotive bearing thiab iav kev lag luam los txhim kho efficiency thiab tau lub sij hawm luv tshaj.
CBN-A20, xim kub, pob tshab monocrystal nrog cov duab tsis tu ncua thiab siab tawv.Zoo heev truncated tetrahedron duab thiab nws tus kheej angular ntse.Zoo heev rau kev xav tau vitrified daim ntawv cog lus thiab cov cuab yeej siv hlau, sib tsoo lub log, kuj tuaj yeem siv rau cov cuab yeej electroplated rau kev ua ferrous hlau thiab alloys.
