Superhard tool material inoreva chinhu chakaoma zvikuru chinogona kushandiswa semudziyo wekucheka. Parizvino, inogona kukamurwa kuita mapoka maviri: diamond yekucheka chishandiso uye cubic boron nitride yekucheka chishandiso. Kune marudzi mashanu makuru emhando nyowani dzakashandiswa kana dziri pasi pekuyedzwa
(1) Yakasikwa uye yekugadzira yakagadzirwa hombe yekristaro dhaimani
(2) Poly diamond (PCD) uye poly diamond composite blade (PDC)
(3) CVD diamond
(4) Polycrystal cubic boron ammonia; (PCBN)
(5) CVD cubic boron ammonia coating
1, yakasikwa uye yakagadzirwa yakakura imwe crystal diamond
Madhaimani echisikigo chimiro chekristaro chakafanana chisina muganho wezviyo zvemukati, kuitira kuti mupendero wemidziyo unokwanisa kusvika paatomu kutsvedzerera uye kupinza, nekugona kwakasimba kwekucheka, kurongeka kwepamusoro uye simba diki rekucheka. Iko kuomarara, kupfeka kuramba uye kusimba kwekudzivirira uye kugadzikana kwemakemikari edhaimani rechisikigo inovimbisa hupenyu hurefu hwechishandiso, inogona kuve nechokwadi chekucheka kwakarebesa, uye kuderedza kukanganiswa kwekupfeka kwechishandiso pakurongeka kwezvikamu zvakagadziridzwa, iyo yakanyanya kupisa conductivity inogona kuderedza tembiricha yekucheka uye deformation yekupisa yezvikamu. Hunhu hwakanaka hwechisikigo hombe imwe yekristaro diamondi inogona kusangana nezvakawanda zvezvinodiwa zvekunyatso uye yekupedzisira-chaiyo kucheka kwezvishandiso zvekushandisa. Kunyangwe mutengo wayo uchidhura, uchiri kuzivikanwa seyakanyanya kurongeka uye ultra precision maturusi emidziyo, inogona kushandiswa zvakanyanya mukugadzira nyukireya reactor uye imwe tekinoroji yepamusoro mumunda wezvionioni, zvombo uye maroketi, komputa hard disk substrate, accelerator electron pfuti super precision machining, uye zvechinyakare zvekuwedzera zvikamu, zvishongo, zvinyoreso, simbi yekushongedza simbi yakashandiswa kugadzira iyo, ophology yekuvhiya, nezvimwe. scalpel, ultra-thin biological blades uye mamwe maturusi ekurapa. Ikozvino kuvandudza tembiricha yepamusoro uye yakanyanya kudzvanywa tekinoroji inoita kuti zvikwanise kugadzirira hombe imwe crystal diamond ine imwe saizi. Kubatsira kweiyi madhaimondi mudziyo wekushandisa hukuru hwayo hwakanaka, chimiro uye performanceOf consistency, iyo isingawanikwe mune zvakasikwa madhaimani zvigadzirwa. Nekuda kwekushomeka kwehukuru hukuru hwekuwanikwa kwedhaimondi, mutengo unodhura, yakagadzirwa hombe chidimbu chekristaro chedhaimani chishandiso mune yekupedzisira-chaiyo yekucheka kugadzirisa seyakasikwa hombe yekristaro yedhaimani chinotsiva, kushandiswa kwayo kuchagadzirwa nekukurumidza.
2, polycrystal diamond (PCD) uye polycrystal diamond composite blade (PDC) zvichienzaniswa nehombe yekristaro yedhaimani sechishandiso chepolycrystal diamond (PCD) uye polycrystal diamond composite blade (PDC) ine zvinotevera zvakanakira: (1) tsanga isina kurongeka kuronga, isotropic, isina cleavage pamusoro. Naizvozvo, haina kufanana nedhaimani hombe rekristaro pane akasiyana ekristaro pamusoro pesimba, kuoma
Uye kupfeka kushorwa kwakasiyana kwazvo, uye nekuda kwekuvapo kweiyo cleavage pamusoro uye ine brittle.
(2) ine simba rakawanda, kunyanya iyo PDC mudziyo wekushandisa nekuda kwekutsigirwa kwecarbide matrix uye ine yakanyanya kusimba kuramba, iyo inokonzeresa inongoburitsa zviyo zvidiki zvakatyoka, kwete seyekristaro yedhaimani kudonha kukuru, nekudaro nePCD kana PDC chishandiso hachingo shandiswa kucheka chaiko uye zvakajairwa hafu chaiyo machining. Asi zvakare inogona kushandiswa seyakakura yekukasira machining uye kupindirana kugadzirisa (sekugaya, nezvimwewo), iyo inowedzera zvakanyanya kushandiswa kwemhando yedhaimondi zvishandiso zvekushandisa.
(3) Yakakura PDC chishandiso chisina chinhu chinogona kugadzirira kuzadzisa zvinodiwa zvematurusi makuru ekugadzira senge milling cutter.
(4) Maumbirwo chaiwo anogona kuitwa kuti asangane nezvinodiwa zvakasiyana-siyana kugadzirisa. Nekuda kwekuvandudzwa kwePDC chishandiso billet uye kugadzira tekinoroji senge electric spark, laser yekucheka tekinoroji, katatu, herringbone, gables uye imwe yakakosha-yakaita blade billet inogona kugadziriswa nekuumbwa. Kuti uwane zvinodiwa zvezvishandiso zvakakosha zvekucheka, zvinogona zvakare kugadzirwa sekuputirwa, sandwich uye roll PDC chishandiso billet.
(5) Kuita kwechigadzirwa kunogona kugadzirwa kana kufanotaurwa, uye chigadzirwa chinopihwa hunhu hunodiwa kuti huenderane nekushandiswa kwacho. Semuyenzaniso, kusarudza yakanaka-grained PDC mudziyo wemidziyo inogona kuvandudza kumucheto kwemhando yechishandiso; coarse-grained PDC chishandiso chekushandisa chinogona kuvandudza kusimba kwechishandiso.
Mukupedzisa, nekuvandudzwa kwePCD nePDC zvishandiso zvekushandisa, kushandiswa kwePCD nePDC chishandiso kwakakurumidza kuwedzerwa kune akawanda ekugadzira.
Indasitiri inoshandiswa zvakanyanya mune zvisiri zvesimbi simbi (aruminiyamu, aruminiyamu chiwanikwa, mhangura, mhangura chiwanikwa, magnesium chiwanikwa, zingi chiwanikwa, etc.), carbide, Ceramics, asiri simbi zvinhu (purasitiki, yakaoma rabha, kabhoni rods, huni, simende zvigadzirwa, nezvimwewo), composite zvinhu (zvakadai sefiberpp, MMC simbi yekucheka simbi inosimbisa, MMC simbi inosimbisa simbi indasitiri yemotokari uye huni yekugadzira, yave yakakwira mashandiro echinyakare carbide.
