CBN yekucheka chishandisosndeyemhando yemhando yepamusoro-soro yekucheka maturusi, ayo anogadzirwa achishandisa ultra-yakakwirira tembiricha uye yakanyanya kudzvanywa tekinoroji uchishandisa CBN poda seyakagadzirwa zvinhu uye diki bhainda.Nekuda kwekuoma kwakanyanya kweCBN yekucheka maturusi, yakanyatsokodzera kugadzirisa zvinhu nekuoma kwakakura kupfuura HRC50 uye yakasimba kupfeka kuramba.
Chii chinonzi CBN?
CBN (cubic boron nitride) chinhu chakanyanya kuoma chishandiso chakagadzirwa mushure medhaimani rekugadzira, iro rinoshandurwa kubva kuhexagonal boron nitride (white graphite) pasi pekupisa kwakanyanya uye kumanikidzwa.CBN isiri-metallic boride, uye kuoma kwayo ndekwechipiri kune dhaimondi, yakakwira zvakanyanya kupfuura simbi yekumhanya uye yakaoma alloy.Naizvozvo, mushure mekugadzirwa kuita maturusi, CBN inonyanya kukodzera kumichina yakamira zvinhu zvine carbide yekucheka maturusi.
Ndezvipi zvinhuCBN kucheka zvishandisoyakakodzera kugadzirisa?
CBN yekucheka maturusi anogona kushandiswa kucheka zvinhu zvakaita sesimbi yakaoma (inotakura simbi, mold simbi, nezvimwewo), simbi yakakandwa (grey cast iron, ductile iron, high chromium cast iron, alloy wear-resistant cast iron, etc.), high-speed simbi, hard alloy, high-temperature alloy, nezvimwewo, uye vane zvakanakira zvikuru muferrous metal processing.
Izvo zvinofanirwa kucherechedzwa kuti kana iyo yekugadzirisa zvinhu iri simbi yakapfava kana isiri-simbi, CBN yekucheka maturusi haana kukodzera kugadzirisa.Maturusi ekucheka eCBN anokurudzirwa chete kana kuoma kwezvinhu kwasvika pane imwe nhanho (HRC> 50).
CommonCBN kuisa mafomu ekugadzirisa
Kazhinji kutaura, maturusi ekucheka anowanzo shandiswa mukushandura machining anonyanya kuve neanotevera mafomu ekumisikidza: akakosha CBN kuisa uye welded CBN yekuisa, pakati peiyo welded CBN yekuisa inosanganisira yakabatanidzwa welded yekuisa uye composite welded yekuisa.
(1) Yakabatanidzwa CBN isa.Iyo yese blade inosiirwa kubva kuCBN micro poda, ine akawanda ekucheka edges.Ese ari maviri epamusoro neazasi blade matipi anogona kushandiswa kucheka, zvichikonzera kushandiswa kwakanyanya kweblade isina chinhu.Uye blade ine simba rekukotama rakakwirira uye inokwanisa kumira kucheka kwepamusoro-soro nekudzika kukuru kwekucheka, kwakakodzera kuenderera mberi, kusina simba kwepakati, uye kusimba kwekucheka kwepakati.Iyo ine hupamhi hwekushanda uye inogona kusangana nezvinodiwa zvehutsinye, semi chaiyo, uye chaiyo machining.
(2) Integral welded CBN isa.Muviri wese wekupinda welding fomu ine yakakwira welding simba uye yepakati gomba chinzvimbo, iyo inogona kutsiva yakananga yekuisa coating.Inokodzera machining mamiriro ane hudzamu hwe<2mm, isina kusimba inopindirana uye inoenderera mberi machining nharaunda, kusangana nezvinodiwa zvesemi precision uye chaiyo machining.
(3) Inosanganiswa welded CBN isa.Mushure mekucheka, madiki eCBN anoumbwa zvidhinha anosungirirwa pane yakaoma alloy substrate kuti igadzire akasiyana anotendeuka uye anofinha mashizha.Kazhinji, mupendero mumwe chete unowanikwa, unonyanya kushandiswa kune chaiwo machining mamiriro.
Parizvino, CBN yekucheka maturusi anoshandiswa zvakanyanya mukati mekunze uye kune dzimwe nyika, kunyanya kucheka zvakaoma kumichina zvinhu mumaindasitiri akadai sekugadzira mota (injini, crankshafts, mabhureki discs, mabhureki madhiramu, nezvimwewo), indasitiri yemuchina wemigodhi (kutenderedza dhaka madziro, slurry pombi, nezvimwewo), inotakura giya indasitiri (hub bearings, slawing bearings, wind power bearings, gears, etc.), uye roller industry (cast iron rollers, high-speed steel rollers, nezvimwewo).
