Nhanganyaya uye kushandiswa kwemadhaimani abrasives
Dhaimondi chinhu chine kuoma kwepamusoro-soro muzvisikwa. Iyo ine yakanyanya kuomarara, yekupisa conductivity uye kupfeka kuramba, saka inoshandiswa zvakanyanya muindasitiri yeabrasive. Nekuvandudzwa kwehunyanzvi hwemaindasitiri,diamond abrasivesdzakagadzirwa kubva kumadhaimondi echinyakare kuenda kumadhaimondi akasiyana ekugadzira uye anoshanda anoumbwa zvinhu, zvichiva chikamu chakakosha chemunda wezvinhu zvakaomesesa, uye anoshandiswa zvakanyanya mumaindasitiri mazhinji epamusoro-soro senge mechanical processing, zvemagetsi, optics, uye simba idzva.
Ⅰ. Basic sumo yemadhaimani abrasives
Diamond abrasives arihupfu kana granular zvinhu yakagadzirwa nekupwanya, kuongorora, uye kucheneswa kwemadhaimani echisikigo kana madhaimondi ekugadzira. Kuoma kwayo kweMohs kunosvika padanho regumi, inova ndiyo inonyanya kuzivikanwa abrasive. Zvichienzaniswa neabrasives echinyakare akadai sealuminium oxide uye silicon carbide, maabrasives edhaimondi ane kugona kwekucheka kwepamusoro uye kusapfeka, uye anogona kukuya nekupolisha zvinhu zvekuomarara zvakanyanya uye kukuvara kwakaderera.
Diamond abrasives anonyanya kusanganisira anotevera mafomu:
Diamond micropowder: Iyo particle size inotangira kubva kumakumi emamicrons kusvika kune nanometers, yakakodzera kune dzakasiyana-siyana dzepamusoro-chaiyo yekupolisha maitiro.
Dhaimondi rinokuya vhiri/kukuya musoro: rinoshandiswa kukuya nekugadzira zvinhu zvakaomarara.
Dhaimondi rakaona blade / dhiri: rinoshandiswa kucheka nekuchera zvinhu zvakaita sedombo, ceramics, girazi, nezvimwe.
Dhaimondi rinokuya mvura/kupolisha paste: rinoshandiswa zvakanyanya mu Ultra-chaizvo kugadzirisa mune zvemagetsi, optics, mold uye mamwe maindasitiri.
Composite diamond zvinhu (PCD/PCBN): inosanganisa dhaimondi nesimbi kana ceramic matrix kugadzira chinhu chinoumbwa chemidziyo nekuomarara uye kusapfeka.
Ⅱ. Minda yekushandisa yedhaimani abrasives
1. Mechanical processing
Madhaimondi abrasives anoshandiswa zvakanyanya mukugadzira uye kugaya kwepamusoro-kuoma zvinhu, zvakadai secemented carbide, ceramics, silicon carbide, girazi, ferrite, etc. Kushandisa mavhiri edhaimondi ekugadzika kwekugadzira hakungogadzirisi zvakanyanya kugadzirisa kushanda uye kunaka kwepamusoro, asiwo kuwedzera hupenyu hwematurusi uye kuderedza kushandiswa kwekugadzirisa kushandiswa. Iyo inonyanya kukodzera kune yakawanda-yakagadzirwa, automated yakakwirira-chaiyo yekugadzira maitiro.
2. Electronics uye semiconductor maindasitiri
Munguva yekugadziriswa kwezvinhu zvakaita sesilicon wafers, sapphire substrates, silicon carbide machipisi, optoelectronic girazi, nezvimwewo, madhaimondi waya masaha, zvinwiwa zvekukuya uye kupukuta mapeji zvinhu zvakakosha zvekushandisa. Diamond abrasives anogona kuwana submicron kana kunyange nanometer-level flatness uye roughness. Iwo anoshandiswa zvakanyanya mumakiyi link senge chip dicing, wafer kugaya, uye photomask polishing. Izvo zvinhu zvakakosha pakuvimbisa kushanda kwepamusoro uye goho repamusoro rezvigadzirwa zvemagetsi.
3. Optical processing
Dhaimondi hupfu hunoshandiswa zvakanyanya mukukwenenzverwa kwegirazi remaziso, laser windows, sapphire lenzi uye zvimwe zvinhu. Simba rayo rakanakisa rekucheka uye kugadzikana kwemakemikari kunogona kunyatso kuvandudza kunaka kwegirazi kugadzirisa uye kuwana hutsinye hwepamusoro Ra isingasviki 10nm. Icho chinhu chakakosha kuti uwane ultra-smooth surfaces uye high light transmittance.
4. Kuvaka uye kugadzirisa matombo
Madhaimondi akasaha mablades, madhiri, waya dzekucheka, nezvimwewo zvinoshandiswa zvakanyanya mukugadzira zvinhu zvekuvakisa zvakaita segranite, marble, nekongiri. Zvichienzaniswa nemidziyo yechinyakare, maturusi edhaimondi akakwirira mukucheka kukurumidza, hupenyu hwebasa, uye kucheka mhando, uye anonyanya kukodzera kugadzirwa kwakanaka kwepamusoro-simba uye yakakwirira-density zvinhu zvekuvaka.
5. Simba idzva uye aerospace
Nekuvandudzwa kwehunyanzvi hwesimba remagetsi, kudiwa kwemadhaimondi abrasives mukugadzirisa kwe lithium bhatiri pole zvidimbu, ceramic diaphragms, zvinhu zvemotokari yemagetsi, nezvimwe zviri kukura nekukurumidza. Mumunda weaerospace, maturusi edhaimondi anoshandiswa kukwenenzvera machining einjini inopisa yekupedzisira zvikamu, zvakaumbwa zvikamu zvechimiro, nezvimwewo, izvo zvinovandudza kuvimbika uye kusimba kwezvigadzirwa.
III. Mhedziso
Madhaimondi abrasives, sechinhu chakakosha chekugadzira maindasitiri emazuva ano, ari kutorwa nekuwedzera uye nepamusoro-chakanyanya-chaiyo machining mamiriro nekuda kweakanakisa zvimiro zvemuviri uye kushanda kwakafara. Mune ramangwana, nekuenderera mberi kwekufambira mberi kwezvinhu zvesainzi uye tekinoroji yekugadzira, madhaimondi abrasives acharamba achikura mune yakanatswa, yakangwara uye ine hushamwari nharaunda, ichibatsira iyo yepamusoro-yekupedzisira indasitiri yekugadzira kuti iende kune imwe nhanho yepamusoro.
