Tlhahlobo ea Litšobotsi tsa Ts'ebetso ea Lisebelisoa tse hlano tsa Superhard Cutting Tool

Superhard tool material e bua ka thepa e thata haholo e ka sebelisoang e le sesebelisoa sa ho itšeha. Hajoale, e ka aroloa ka mekhahlelo e 'meli: lisebelisoa tsa ho itšeha tsa daemane le li-cubic boron nitride cutting tool. Ho na le mefuta e mehlano ea mantlha ea lisebelisoa tse ncha tse sebelisitsoeng kapa tse ntseng li lekoa

(1) Taemane e kholo ea kristale ea tlhaho le ea maiketsetso

(2) Poly diamond (PCD) le poly diamond composite blade (PDC)

(3) Taemane ea CVD

(4) Polycrystal cubic boron ammonia; (PCBN)

(5) CVD cubic boron ammonia coating

1, ea tlhaho le ea maiketsetso e kholo ea taemane e le 'ngoe ea kristale

Taemane ea tlhaho ke sebopeho sa kristale se ts'oanang ntle le moeli oa lijo-thollo tse ka hare, e le hore moeli oa sesebelisoa o ka fihla ho boreleli ba athomo le bohale, ka bokhoni bo matla ba ho itšeha, ho nepahala ho phahameng le matla a manyenyane a ho itšeha. The thatafala, apare ho hanyetsa le kutu ho hanyetsa le botsitso lik'hemik'hale tsa daemane tlhaho etsa bonnete ba hore bophelo bo bolelele ba sesebelisoa, ka etsa bonnete ba hore nako e telele e tloaelehileng ho itšeha, 'me ho fokotsa tšusumetso ea ho apara sesebelisoa ka ho nepahala ha likarolo sebetswa, conductivity lona phahameng mogote ka fokotsa mocheso itšeha le deformation mogote oa likarolo. Litšobotsi tse ntle tsa daemane e kholo ea kristale e le 'ngoe e ka fihlela litlhoko tse ngata tsa ho nepahala le ho itšeha haholo bakeng sa lisebelisoa tsa lisebelisoa. Le hoja theko ea eona e theko e boima, e ntse e nkoa e le lisebelisoa tsa lisebelisoa tse nepahetseng le tse nepahetseng, tse ka sebelisoang haholo ho sebetsana le lisebelisoa tsa nyutlelie le thekenoloji e 'ngoe e phahameng tšimong ea liipone, limisaele le lirokete, k'homphieutha e thata ea disk substrate, accelerator electron gun super precision machining, le likarolo tsa tloaelo tsa ho shebella, mabenyane, lipene, mokhabiso oa tšepe oa sephutheloana o sebelisoang ho sebetsa ka mokhoa o nepahetseng oa boko, joalo-joalo. scalpel, ultra-thin biological blades le lisebelisoa tse ling tsa bongaka. Tsoelo-pele ea hona joale ea mocheso o phahameng le theknoloji ea khatello e phahameng e etsa hore ho khonehe ho lokisetsa daemane e kholo ea kristale e le 'ngoe ka boholo bo itseng. Monyetla oa thepa ena ea daemane ke boholo ba eona bo botle, sebōpeho le tshebetsoOf consistency, e sa finyelloang lihlahisoa tsa daemane tsa tlhaho. Ka lebaka la khaello ea phepelo ea daemane ea tlhaho ea boholo bo boholo, theko e theko e phahameng, sesebelisoa se seholo sa maiketsetso sa kristale se le seng se entsoeng ka mokhoa o hlakileng oa ho itšeha e le sebaka sa tlhaho se seholo sa daemane sa kristale, ts'ebeliso ea eona e tla ntlafatsoa ka potlako.

2, polycrystal diamond (PCD) le polycrystal diamond composite blade (PDC) ha e bapisoa le daemane e kholo ea kristale e le 'ngoe e le sesebelisoa sa polycrystal diamond (PCD) le polycrystal diamond composite blade (PDC) li na le melemo e latelang: (1) tlhophiso ea lijo-thollo, isotropic, ha ho na bokaholimo ba cleavage. Ka hona, ha e tšoane le taemane e kholo ea kristale e le 'ngoe ka matla a fapaneng a holim'a kristale, boima

'Me ho hanyetsa ho roala ho fapane haholo,' me ka lebaka la ho ba teng ha sebaka sa cleavage 'me ke brittle.

(2) e na le matla a phahameng, haholo-holo lisebelisoa tsa lisebelisoa tsa PDC ka lebaka la ts'ehetso ea carbide matrix 'me e na le ts'ebetso e phahameng ea ho hanyetsa, phello e tla hlahisa lijo-thollo tse nyenyane tse robehileng, eseng joaloka kristale e le' ngoe ea taemane ea ho oa ho hoholo, kahoo ka sesebelisoa sa PCD kapa PDC ha se feela se ka sebelisoang bakeng sa ho itšeha ka ho nepahetseng le ho sebetsa ka mokhoa o tloaelehileng oa halofo. Empa hape e ka sebelisoa e le palo e kholo ea machining a thata le ts'ebetso ea nakoana (joalo ka ho sila, joalo-joalo), e eketsang haholo tšebeliso ea lisebelisoa tsa lisebelisoa tsa daemane.

(4) Libopeho tse khethehileng li ka etsoa ho finyella litlhoko tsa ts'ebetso e fapaneng. Ka lebaka la ntlafatso ea PDC tool billet le theknoloji ea ho sebetsa e kang spark ea motlakase, thekenoloji ea laser cutting, triangle, herringbone, gables le billet e 'ngoe e nang le sebōpeho se khethehileng ea lehare e ka sebetsoa le ho thehoa. E le ho finyella litlhoko tsa lisebelisoa tse khethehileng tsa ho itšeha, e ka boela ea etsoa e le phuthetsoe, sandwich le roll PDC tool billet.

(5) Ts'ebetso ea sehlahisoa e ka raloa kapa ea boleloa esale pele, 'me sehlahisoa se fuoa litšobotsi tse hlokahalang ho ikamahanya le ts'ebeliso ea sona e ikhethileng. Ka mohlala, ho khetha lisebelisoa tsa lisebelisoa tsa PDC tse entsoeng hantle ho ka ntlafatsa boleng ba lisebelisoa; lisebelisoa tsa lisebelisoa tsa PDC tse mahoashe li ka ntlafatsa ho tšoarella ha sesebelisoa.

Qetellong, ka nts'etsopele ea lisebelisoa tsa lisebelisoa tsa PCD le PDC, ts'ebeliso ea sesebelisoa sa PCD le PDC e atolositsoe ka potlako ho lihlahisoa tse ngata.

Indasteri ho pharaletseng sebelisoa ka tšepe bao e seng ferrous (aluminium, aluminium motsoako, koporo, koporo motsoako, magnesium motsoako, alloy zinki, joalo-joalo), carbide, ceramics, thepa bao e seng tšepe (polasetiki, rabara ka thata, melamu carbon, lehong, lihlahisoa tsa samente, joalo-joalo), lisebelisoa composite (tse kang fiber CFRP, haholo-holo matrix ho itšeha, MMC ka polasetiki ho itšeha ka tšepe reinforced indasteri ea ho lokisa likoloi le patsi, e se e le carbide ea setso e sebetsang hantle haholo.
