Parizvino, indasitiri yekugadzira michina yeChina iri kusimukira nekukurumidza, uye zvimwe zvinhu zvakaoma kucheka zvinoshandiswa zvakanyanya muindasitiri yezvigadzirwa uye indasitiri yemakina.Kuti tisangane nezvinodiwa zvekusimudzira zvemaindasitiri emazuva ano ekugadzira michina, tinoda kushandisa mamwe maturusi ane simba repamusoro uye nekusimba kwakanaka.Naizvozvo, maturusi emidziyo yakaoma anoshandiswa zvishoma nezvishoma kuindasitiri yekugadzira michina.Ichi chinyorwa chinotarisana nekushandiswa kwezvishandiso zvezvinhu zvakaoma mukugadzira tichitarisa kuvandudzwa kwezvishandiso zvezvinhu zvakaoma, kuitira kuti zvipe kuwirirana kune shamwari dziri muindasitiri imwe chete.
Nekukurumidza kusimudzira tekinoroji yemazuva ano yekugadzira uye kukwikwidza kunotyisa kwemusika, izvo zvinodikanwa zvemuchina wekugadzira indasitiri yezvikamu zvemichina zvemichina zviri kuwedzerawo, kunyanya pakuita kwemaitiro ezvikamu zvemakanika.Naizvozvo, zvinhu zvitsva zvine zvimiro zvakasiyana zvishoma nezvishoma zvakabuda munharaunda.Zvishandiso zvitsva izvi hazvingounze dambudziko rakakomba kune echinyakare machining maturusi, asi zvakare akaoma kwazvo kugadzirisa.Panguva ino, maturusi epamusoro ekucheka aita kiyi yekusimudzira indasitiri yekugadzira michina, uye maturusi emidziyo yakaoma pasina mubvunzo akaiswa kune yemazuva ano mechanical processing.
1. Nhoroondo yekuvandudza yemidziyo yakaoma
Mumakore ekuma1950s, masayendisiti eAmerica akatora madhaimani ekugadzira, bond, uye boron carbide poda semidziyo yakabikwa, yakaitwa pasi pekupisa kwakanyanya uye kumanikidzwa, uye sintered polycrystalline block sechinhu chikuru chechishandiso.Mushure memakore ekuma1970, vanhu zvishoma nezvishoma vakagadzira mashizha emusanganiswa, ayo anogadzirwa nekubatanidza madhaimondi uye simende carbide, kana boron nitride uye simende carbide.Mune tekinoroji iyi, simende carbide inoonekwa seyo substrate, uye dhaimondi rinoumbwa pamusoro peiyo substrate nekutsikirira kana sinter.Dhaimondi rinenge 0.5 kusvika 1 mm gobvu.Zvishandiso zvakadaro hazvingogone kuvandudza kupeta kwekupokana kwezvinhu, asi zvakare zvinobudirira kugadzirisa dambudziko rekuti zvinhu zvechinyakare hazvisi nyore kubatanidza.Izvi zvakasimudzira chishandiso chakaoma chekushandisa kupinda muchikamu chekushandisa.
2. Kushandiswa kwezvinhu zvakaoma maturusi mukugadzira
(1) Kushandiswa kweimwe crystal diamond maturusi
Single crystal diamond inowanzo kupatsanurwa kuita dhaimani rekugadzira uye dhaimondi rechisikigo.Kazhinji, kana dhaimondi rimwechete rekristaro richishandiswa kugadzira chishandiso, zvinodikanwa kuti usarudze dhaimondi nehukuru hukuru hukuru, huremu hwakakura kupfuura 0.1 g uye kureba kwakakura kupfuura 3 mm.Parizvino, dhaimondi rechisikigo ndiro rakaomesesa zvinhu mumaminerari.Haisi chete ine yakanaka yekupfeka kuramba, asiwo chishandiso chakaitwa nacho chakapinza kwazvo.Panguva imwecheteyo, ine yakakwirira adhesion resistance uye yakaderera thermal conductivity.Chishandiso chakagadziriswa chakatsetseka uye chemhando yakanaka.Panguva imwecheteyo, chishandiso chakagadzirwa nedhaimani rechisikigo chine kusimba kwakanyanya uye hupenyu hurefu hwebasa.Mukuwedzera, kana uchicheka kwenguva yakareba, hazvizokanganisa kugadzirisa kwezvikamu.Iyo yakaderera yekupisa conductivity inogona kuve nemhedzisiro yakanaka pakudzivirira deformation yezvikamu.
Natural diamond ine zvakawanda zvakanakira.Kunyange zvazvo zvakanakira izvi zvichidhura, zvinogona kusangana nezvinodiwa zveakawanda akanyanya-chaiyo kucheka mashandiro uye anoshandiswa zvakanyanya mukucheka kwakaringana uye kutema kwekupedzisira.Sekuona magirazi anoshandisa maatomu emagetsi uye mamwe matekinoroji epamusoro, pamwe neatomu yekufambisa gyroscopes anoshandiswa pazvombo zvekupotsera kana maroketi, pamwe nezvimwe zvikamu zvewachi, zvishongedzo zvesimbi, nezvimwewo, zvakashandisa tekinoroji iyi.
(2) Kushandiswa kwe polycrystalline diamond maturusi
Polycrystalline diamond inowanzonzi sintered diamond.Kushandiswa kwedhaimondi yepolycrystalline yesimbi dzakadai secobalt, kuburikidza nekupisa kwakanyanya uye nepamusoro-soro mamiriro ezvinhu, kuchaita kuti dhaimondi rimwechete rimwechete recrystal poda polycrystalline rive rimwe, nokudaro richigadzira polycrystalline tool material.Kuomarara kwepolycrystalline diamond yakadzikira pane yedhaimondi rechisikigo.Zvisinei, inoumbwa nemhando dzakasiyana-siyana dzedhaimani poda, uye hapana nyaya yekuti ndege dzakasiyana dzekristal dzine simba rakasiyana uye kuoma.Paunenge uchicheka, iyo yekucheka inogadzirwa ne polycrystalline diamond ine yakanyanya kupikisa kukuvara netsaona uye kupfeka kwakanaka kuramba.Inogona kuchengetedza kuchekwa kwakapinza kwenguva yakati rebei.Panguva imwecheteyo, inogona kushandisa kukurumidza kucheka kumhanya kana uchigadzira.Zvichienzaniswa neWC cemented carbide maturusi, polycrystalline diamond maturusi ane hupenyu hurefu hwesevhisi, kuwanikwa kuri nyore kwezvinhu zvekugadzira uye mitengo yakaderera.
(3) Kushandiswa kweCVD diamond
Chishandiso cheCVD dhaimondi chinogadziriswa pasi pekumanikidzwa kwakaderera, ndiwo mutsauko mukuru kubva kune yechinyakare PSC tekinoroji uye PDC tekinoroji.CVD diamond haina chero chinhu chinokonzeresa.Kunyangwe yakafanana nedhaimondi rechisikigo mune zvimwe zvivakwa, ichiri yakafanana nedhaimondi repolycrystalline mumidziyo, ndiko kuti, zviyo zvekuumbwa hazvina kurongeka, kushaikwa kwebrittle cleavage pamusoro, uye zvine zvinhu zvakafanana pakati penzvimbo.Zvichienzaniswa nemidziyo yakagadzirwa nehunyanzvi hwechinyakare, maturusi akagadzirwa neCVD tekinoroji yedhaimani ane zvimwe zvakanakira, senge zvakaomarara maturusi chimiro, mutengo wakaderera wekugadzira, uye akawanda mablade eblade imwechete.
(4) Kushandiswa kwepolycrystalline cubic boron nitride
Polycrystalline cubic boron nitride (PCBN) chinhu chakajairika chakaoma zvinhu chishandiso, icho chinowedzera uye chinoshandiswa zvakanyanya mukugadzira.Chishandiso chakagadzirwa neiyi tekinoroji chine kuomarara kwakanyanya uye kupfeka kuramba.Iyo haigone kungoshandiswa chete pane yakanyanya kudziya tembiricha, asi zvakare ine yakanakisa corrosion resistance uye thermal conductivity.Zvichienzaniswa nePCD nePDC maturusi, polycrystalline cubic boron nitride maturusi achiri akaderera mukupfeka kuramba, asi anogona kushandiswa zvakajairika pa1200 ℃ uye anogona kumirisana nekumwe kwemakemikari kukora!
Parizvino, polycrystalline cubic boron nitride inonyanya kushandiswa mukugadzira mota, senge injini dzemotokari, transmission shafts, uye brake discs.Pamusoro pezvo, chinenge chikamu chimwe muzvishanu chekugadzira michina inorema inoshandisawo tekinoroji iyi.Mumakore achangopfuura, nekuvandudzwa kwekombuta tekinoroji uye CNC muchina chishandiso tekinoroji, kushandiswa kwepolycrystalline cubic boron nitride kwave kuwedzera kupararira, uye nekushandiswa kwepamusoro machining concepts sekucheka-kumhanya, kutendeuka pachinzvimbo chekukuya, chishandiso. zvinhu zvepolycrystalline cubic boron nitride zvishoma nezvishoma zvakakura kuita chinhu chakakosha mukuchinja kwemazuva ano.
3. Pfupiso
Kushandiswa kwezvishandiso zvemidziyo yakaoma mukugadzira hakungogadzirise kunaka uye kugona kwemuchina, asi zvakare kunoita basa rakakosha mukusimudzira indasitiri yekugadzira michina.Naizvozvo, kuitira kusimudzira kusimudzira indasitiri yekugadzira michina, zvinodikanwa kuramba uchisimbisa kutsvagisa kwezvishandiso zvakaoma, kunyatsonzwisisa ruzivo rwune chekuita nemidziyo yakaoma, uye kusimbisa maitiro ekushandisa, kwete kungovandudza mhando yemidziyo. vashandi, asi zvakare kusimbisa kushandiswa kwesainzi uye tekinoroji mukuvandudza maturusi emidziyo yakaoma, kuitira kuti vaone kukwidziridzwa kweiyo mechanical processing industry.
