Sesebelisoa sa ho itšeha sa CBNske ea mofuta oa lisebelisoa tsa ho itšeha tse thata haholo, tse entsoeng ka mocheso o phahameng haholo le theknoloji e phahameng ea khatello e sebelisang phofo ea CBN e le thepa e tala le palo e nyane ea binder.Ka lebaka la boima bo phahameng ba lisebelisoa tsa ho itšeha tsa CBN, e loketse haholo bakeng sa lisebelisoa tsa ho sebetsa tse thata ho feta HRC50 le khanyetso e matla ea ho roala.
CBN ke boitsebiso bofe?
CBN (cubic boron nitride) ke sesebelisoa se matla haholo se entsoeng ka mor'a taemane ea maiketsetso, e fetotsoeng ho tloha ho hexagonal boron nitride (white graphite) tlas'a mocheso o phahameng le khatello.CBN ke boride e seng tšepe, 'me ho thatafala ha eona ke ea bobeli ho daemane, e phahame haholo ho feta tšepe e lebelo le thata le alloy e thata.Ka hona, ka mor'a ho etsoa lisebelisoa, CBN e loketse haholoanyane bakeng sa ho etsa thepa e emeng e nang le lisebelisoa tsa ho itšeha carbide.
Ke lisebelisoa lifeHo khaola CBN lisebelisoae loketseng ho sebetsa?
Lisebelisoa tsa ho itšeha tsa CBN li ka sebelisoa ho seha lisebelisoa tse kang tšepe e thata (tšepe e nang le tšepe, tšepe ea hlobo, jj.), tšepe e entsoeng ka tšepe (tšepe e bohlooho, tšepe ea ductile, tšepe e phahameng ea chromium, tšepe e sa sebetseng ea alloy, jj.), tšepe ea lebelo le phahameng, alloy e thata, alloy e phahameng ea mocheso, joalo-joalo, 'me e na le melemo e meholo ts'ebetsong ea tšepe ea tšepe.

Ka kakaretso, lisebelisoa tsa ho itšeha tse sebelisoang hangata ho fetoleng machining haholo-holo li na le mefuta e latelang ea meralo: ho kenya CBN ea bohlokoa le ho kenya CBN e kentsoeng, eo ho eona ho kenyelletsoang CBN ho kenyelletsa kenyelletso e kenyellelitsoeng e kenyelletsoeng le ho kenya motsoako o kopantsoeng.
(1) Ho kenya CBN e kopantsoeng.Lehare lohle le siiloe ho tsoa ho phofo e nyane ea CBN, e nang le likarolo tse ngata tse sehiloeng.Malebela a ka holimo le a tlase a ka sebelisoa bakeng sa ho seha, e leng se bakang tšebeliso e phahameng ea lehare le se nang letho.'Me lehare le na le matla a holimo a ho kobeha' me le khona ho mamella ho itšeha ka lebelo le phahameng ka botebo bo boholo ba ho itšeha, bo loketseng libaka tse sa khaotseng, tse fokolang le tse matla tsa ho itšeha.E na le ts'ebeliso e pharaletseng 'me e ka fihlela litlhoko tsa ho sebetsa ka thata, ho nepahala le ho sebetsa ka nepo.
(2) Integral welded CBN kenya.'Mele oohle oa ho kenella ka tjheseletsa o na le matla a phahameng a ho tjheseletsa le boemo bo bohareng ba lesoba, e leng se ka nkang sebaka sa ho kenya letsoho ka ho toba.E loketse maemo a machining a botebo ba <2mm, libaka tse fokolang tse fokolang le tse tsoelang pele tsa machining, tse finyellang litlhoko tsa semi precision le machining e nepahetseng.
(3) Kenyelletso ea CBN e kopantsoeng e kopantsoeng.Kamora ho seha, li-block tse nyane tse kopaneng tsa CBN li hokeloa holim'a substrate e thata ea alloy ho etsa mahare a fapaneng a fetohang le a bora.Ka kakaretso, ho na le moeli o le mong feela o fumanehang, haholo-holo o sebelisetsoang maemo a machining a nepahetseng.
Hajoale, lisebelisoa tsa ho itšeha tsa CBN li sebelisoa haholo ka hare ho naha le kantle ho naha, haholo-holo bakeng sa ho seha lisebelisoa tse thata tsa mochini ho liindasteri tse kang ho etsa likoloi (lienjiniere, li-crankshafts, li-brake discs, meropa ea brake, joalo-joalo), indasteri ea meepo (marako a seretse, lipompo tsa slurry, joalo-joalo), tse nang le indasteri ea lisebelisoa (li-hub bearings, slewing bearings, wind bear bearings, gears, joalo-joalo), le indasteri ea li-roller (li-roller tsa tšepe tse entsoeng ka tšepe, li-roller tsa tšepe tse lebelo, joalo-joalo).
