Likarolo tsa Milling Cutters
Ha u sebetsana le lisebelisoa tse thata tsa mochine tse kang Hastelloy, waspaloy, Inconel le Kovar, tsebo ea machining le phihlelo ke tsa bohlokoa haholo. Hona joale, ho na le lisebelisoa tse ngata tsa li-alloys tse thehiloeng ho nickel, haholo-holo tse sebelisetsoang ho etsa likarolo tse ling tsa bohlokoa lefapheng la lifofane, tsa bongaka le tsa lik'hemik'hale. Lisebelisoa tsena li na le matla a holimo, li hanyetsa ho bola, 'me li khona ho mamella mocheso o phahameng haholo. Lintho tse ling tse khethehileng li kenyelletsoa lisebelisoa tse ka holimo ho fumana ts'ebetso e phahameng. Leha ho le joalo, ka lehlakoreng le leng, thepa ena le eona e ba thata haholo ho sila.
Rea tseba hore nickel le chromium ke lisebelisoa tse peli tse ka sehloohong tsa li-alloys tse thehiloeng ho nickel. Ho eketsa nickel ho ka eketsa ho tiea ha thepa, ho eketsa chromium ho ka ntlafatsa ho thatafala ha thepa, 'me ho leka-lekana ha likarolo tse ling ho ka sebelisoa ho bolela esale pele ho apara ha sesebelisoa. Lintho tse ling tse ekelitsoeng ho thepa li ka kenyelletsa: silicon, manganese, molybdenum, tantalum, tungsten, joalo-joalo Ke habohlokoa ho hlokomela hore tantalum le tungsten le tsona ke likarolo tse ka sehloohong tse sebelisetsoang ho etsa carbide e entsoeng ka samente, e ka ntlafatsang ka katleho ts'ebetso ea carbide e entsoeng ka samente , empa ho eketsoa ha likarolo tsena ho thepa ea workpiece ho etsa hore ho be thata ho sila, hoo e batlang e le ho khaola sesebelisoa se le seng sa carbide le se seng.
Hobaneng ha li-milling cutters li seha lisebelisoa tse ling li robeha ka potlako ha ho siloa li-alloys tse thehiloeng ho nickel? Ho bohlokoa ho utloisisa sena. Ho etsa li-alloys tse thehiloeng ho nickel, theko ea lisebelisoa e holimo, 'me litšenyehelo ke makhetlo a 5 ho isa ho a 10 ho feta a tšepe e tloaelehileng ea ho sila.
Ha ho pelaelo hore mocheso ke ntho ea bohlokoa ka ho fetisisa e amang bophelo ba lisebelisoa ha ho sila li-alloys tse thehiloeng ho nickel, hobane esita le lisebelisoa tse ntle ka ho fetisisa tsa carbide li ka senngoa ke mocheso o feteletseng oa ho itšeha. Ho hlahisa mocheso o phahameng haholo ha se bothata feela bakeng sa li-alloys tsa nickel. Kahoo, ha ho siloa metsoako ena, mocheso o lokela ho laoloa. Ho phaella moo, ke habohlokoa haholo ho tseba boleng ba mocheso o hlahisoang ha ho etsoa machining ka mefuta e sa tšoaneng ea lisebelisoa (lisebelisoa tsa tšepe tse phahameng ka potlako, lisebelisoa tsa carbide kapa lisebelisoa tsa ceramic).
Tšenyo e ngata ea lisebelisoa e boetse e amana le lintlha tse ling, 'me lisebelisoa tse sa tsitsang le ba nang le lisebelisoa li ka khutsufatsa bophelo ba lisebelisoa. Ha boima ba "clamped workpiece" bo sa lekaneng 'me ho sisinyeha ho etsahala nakong ea ho itšeha, ho ka baka ho robeha ha matrix a samente ea carbide. Ka linako tse ling mapetsong a manyenyane a hlaha haufi le moeli oa ho itšeha, 'me ka linako tse ling sengoathoana se robeha ho kenya carbide, e leng se etsang hore ho se ke ha khoneha ho tsoela pele ho seha. Ha e le hantle, ho senya hona ho ka boela ha bakoa ke carbide e thata haholo kapa mojaro o mongata oa ho itšeha. Ka nako ena, lisebelisoa tsa tšepe tse lebelo le phahameng li lokela ho nahanoa bakeng sa ts'ebetso ho fokotsa ketsahalo ea ho phunya. Ha e le hantle, lisebelisoa tsa tšepe tse lebelo le phahameng li ke ke tsa mamella mocheso o phahameng joaloka carbide e entsoeng ka samente. Hantle-ntle ke lintho life tse tla sebelisoa li tlameha ho khethoa ho latela maemo.
