Ka nts'etsopele ea mahlale a morao-rao, lisebelisoa tsa carbide li fetohile lihlahisoa tse ka sehloohong tsa lisebelisoa tsa machining tsa CNC. Phuputso e bontšitse hore ho kenya carbide ke karolo e phahameng ka ho fetisisa ea thekiso ea lisebelisoa tsa carbide, hoo e ka bang 50%. Lisebelisoa tsa carbide li sebelisoa ho mechine e mengata ea CNC hona joale. Hobaneng u khetha ho kenya li-carbide mochining oa CNC?

• Hobaneng u khetha ho kenya li-carbide mochining oa CNC?

• Ts'ebeliso ea li-carbide tse kentsoeng mochining oa CNC

• Nts'etsopele ea nakong e tlang ea li-carbide tse kentsoeng mochining oa CNC

1. Ke hobane'ng ha u khetha ho kenya carbide ho CNC machining?

Carbide e kenya, joalo ka ha lebitso le bontša, thepa ea eona e ka sehloohong ea tlhahiso ke carbide e samente. Carbide e entsoeng ka samente e entsoe ka carbide ea tšepe ea refractory le phofo ea tšepe ea tšepe ka mor'a ho sebetsa. Hobane li-carbide tsena tsa tšepe li na le ntlha e phahameng ea ho qhibiliha, boima bo phahameng le botsitso bo botle ba lik'hemik'hale, li-carbides tse entsoeng ka samente tse nang le palo e kholo ea li-carbides tsa tšepe tse refractory le tsona li na le litšobotsi tsa li-carbides tsena tsa tšepe tse refractory. Ka hona, ho kenngoa ha carbide ho na le boima bo phahameng, ho hanyetsa ho apara, le ho hanyetsa mocheso. Ho thatafala ha li-carbide tse sebelisoang hangata ke 89～93HRA, e phahameng ho feta ho thatafala ha tšepe ea lebelo le phahameng (83～86.6HRA). 'Me ho kenngoa ha carbide ho hanyetsa mocheso o phahameng. Lisebelisoa tsa carbide li ka khaola lisebelisoa ka mocheso o phahameng oa 800 ~ 1000℃. Ts'ebetso ea ho itšeha ea ho kenya carbide e phahame haholo ho feta ea lisebelisoa tsa tšepe tse phahameng. Ho tšoarella ha li-carbide tse kentsoeng ke makhetlo a 'maloa ho feta tse ling. Ha ho tšoarella ho tšoana, ho kenya carbide ho ka eketsa lebelo la ho itšeha ka makhetlo a 4 ho isa ho a 10.

2. Kopo ea lisebelisoa tsa carbide ho machining a CNC

Ka lebaka la boima bo phahameng le ho hanyetsa mocheso oa ho kenya carbide. Ka hona, machining a CNC hangata a khetha lisebelisoa tsa ho itšeha tsa carbide bakeng sa lathes ho seha thepa. Lisebelisoa tse kopaneng, lipolasetiki tsa indasteri, lisebelisoa tsa likhalase tsa tlhaho le lisebelisoa tsa tšepe tse se nang ferrous 'marakeng kaofela li sehiloe le ho sebetsoa ka lisebelisoa tsa ho itšeha ka carbide bakeng sa lathes. Carbide e entsoeng ka samente e arotsoe ka mekhahlelo e 'meli: tungsten-cobalt alloy (YG) le tungsten-cobalt-titanium alloy (YT). Li-alloys tsa tungsten-cobalt li na le boima bo botle. Lisebelisoa tse entsoeng ka li-alloys tsa tungsten-cobalt li bonolo ho holofala nakong ea ho itšeha, ho itšeha ho bonolo ebile ho potlakile, 'me li-chips ha li bonolo ho khomarela thipa. Ka hona, ka kakaretso, re tla khetha lisebelisoa tse entsoeng ka motsoako oa tungsten-cobalt ho sebetsa tšepe e sa hloekang. Alloy ea Tungsten-cobalt-titanium e hanyetsana ho feta tungsten-cobalt alloy tlas'a maemo a phahameng a mocheso. Empa e brittle ebile ha e hanyetsane le tšusumetso. Ka hona, re tla khetha lisebelisoa tse entsoeng ka motsoako oa tungsten-cobalt-titanium ho sebetsana le lisebelisoa tsa polasetiki tse kang tšepe.

3. Nts'etsopele ea nakong e tlang ea li-carbide tse kenyang mochine oa CNC

Ka nts'etsopele e tsoelang pele ea mahlale le thekenoloji le ntlafatso e tsoelang pele ea boemo ba tlhahiso, phetoho ea lisebelisoa tsa mochini ho tloha ho mechini e tloaelehileng ho ea ho mechini ea CNC ke mokhoa o ke keng oa thijoa. Lisebelisoa tsa ho itšeha tsa Carbide bakeng sa lathes li phetha karolo ea bohlokoa tokisong le ntlafatsong ea sebopeho sa indasteri. Lisebelisoa tsa ho itšeha tsa Carbide bakeng sa lathes li ka ntlafatsa ka nepo chai ea sehlahisoa le boleng. Taolo ea linomoro tsa mochini ke mokhoa oa ntlafatso oa indasteri ea mochini, 'me tlhoko ea lisebelisoa tsa ho laola lipalo le eona e tla hola. Joalo ka karolo ea bohlokoa ea mechini ea tšepe ea CNC e sehang, ho kenya carbide ho tla tsamaisa tlhoko ea bareki ea lisebelisoa tsa CNC, ekaba litlhoko tsa lisebelisoa tsa lisebelisoa tsa mochini oa stock kapa tlhoko e ntseng e eketseha ea lisebelisoa tse ncha tsa mochini selemo se seng le se seng. Ka nako e ts'oanang, ho kenngoa ha carbide ke lintho tse ka sebelisoang. Haeba li-carbide li kenngoa ka tekanyo e itseng, li hloka ho nkeloa sebaka ka nako. Ka hona, tlhoko ea ho kenya carbide 'marakeng e ntse e le ngata.

Ka holimo ke litaba tsohle tsa sehlooho sena, ke tšepa hore sehlooho sena se ka rarolla bothata ba hau 'me sa u thusa ho khetha li-carbide tse ntle ka ho fetisisa. Haeba u e hloka, amohela ho ikopanya le rona. Re moetsi oa litsebi 'me re ka u fa lihlahisoa tse ntle ka ho fetisisa bakeng sa hau, tse kang li-tungsten carbide inserts, carbide grooving insert, carbide threading insert.
