Ni izihe nyungu za granite platforms ugereranyije n'izindi platforms zo kugenzura mu igenzura ry'ibyuma bya moteri z'ikirere?

Ese?
Igenzura ry’ibyuma bya moteri y’ikirere rifite ibisabwa byinshi kugira ngo urubuga rube ruhamye, rufite ukuri kandi rwizewe. Ugereranyije n’ibikoresho bisanzwe byo kugenzura nka icyuma gikozwe mu cyuma na aluminiyumu, ibikoresho bya granite bigaragaza ibyiza bidasubirwaho mu bimenyetso byinshi by’ingenzi.
I. Gukomera ku bushyuhe: "Ubwishingizi karemano" mu kurwanya ubushyuhe bukabije
Igipimo cy’ubushyuhe bw’ibikoresho by’icyuma gishongeshejwe ni hafi 10-12 × 10⁻⁶/℃, naho icya aluminiyumu kikaba hejuru ya 23 × 10⁻⁶/℃. Mu gihe cy’ubushyuhe buterwa n’imikorere y’ibikoresho byo gupima cyangwa ihindagurika ry’ubushyuhe bw’ibidukikije, impinduka z’ibipimo zishobora kubaho, bigatera amakosa yo kuvumbura. Igipimo cy’ubushyuhe bw’ibikoresho by’icyuma gishongeshejwe ni (4-8) × 10⁻⁶/℃ gusa. Mu gihe cy’ihindagurika ry’ubushyuhe rya ± 5℃, impinduka z’ibipimo by’ibikoresho by’icyuma gishongeshejwe gifite uburebure bwa metero 1 ni munsi ya 0.04μm, ibyo bikaba bishobora kwirengagizwa. Iki kimenyetso cyo kwaguka kw’ubushyuhe buke cyane gitanga ubuso buhamye bw’ibikoresho by’ubuhanga nka interferometer za laser n’imashini zipima eshatu, birinda gutandukana kw’imiterere y’amasasu bitewe no guhinduka k’ubushyuhe.

Ii. Imikorere yo kurwanya guhindagura: "Inzitizi Ikora neza" yo Kurandura ikibazo cyo guhindagura
Mu iduka ry’inganda zikora indege, guhindagurika kw’ibidukikije guterwa n’imikorere y’ibikoresho by’imashini no kugenda kw’abakozi ni kenshi. Imbuga za aluminiyumu nta bukonje buhagije zifite, kandi imbuga za aluminiyumu zifite ubushobozi buke bwo guhindagurika, bigatuma bigorana guhindagurika neza. Imiterere ya kristale nini iri imbere muri platform ya granite iha imiterere myiza yo guhindagurika, ifite igipimo cyo guhindagurika cya 0.05-0.1, kingana n’inshuro eshanu z’icyuma gishongeshejwe n’inshuro icumi z’icyuma gishongeshejwe. Iyo guhindagurika kw’inyuma kwoherejwe kuri platform, bishobora kugabanya ingufu zo guhindagurika ho hejuru ya 90% mu masegonda 0.3, bigatuma ibikoresho byo gupima bishobora gutanga amakuru nyayo mu kirere gishongeshejwe.
Iii. Ubukomezi n'Ubudahangarwa: "Igihome Gikomeye" Gituma habaho ubwiza bw'igihe kirekire
Nyuma yo gukoreshwa igihe runaka, urwego rw'icyuma gishongeshejwe rukunze kwangirika, ibyo bigatera ingaruka ku buryo rukora neza. Urwego rw'icyuma gishongeshejwe rufite ubukana buke kandi ntirushobora kwangirika, bigatuma bigorana kwihanganira ikoreshwa ry'ibikoresho biremereye byo kugenzura. Ubucucike bw'urwego rw'icyuma gishongeshejwe bugera kuri 2.6-2.8g / cm³, imbaraga zarwo zo gukanda zirenga 200MPa, kandi ubukana bwa Mohs ni 6-7. Iyo rushyizwe mu biremereye no gukururana igihe kirekire n'ibikoresho byo kugenzura ibyuma, ntabwo rushobora kwangirika cyangwa guhinduka. Amakuru aturuka mu kigo runaka cy'indege agaragaza ko nyuma yo gukoreshwa mu gihe cy'imyaka umunani, impinduka z'urwego rw'icyuma gishongeshejwe ziracyagenzurwa muri ± 0.1μm / m, mu gihe urwego rw'icyuma gishongeshejwe rugomba kongera gupimwa nyuma y'imyaka itatu gusa.
Iv. Gukomera mu bya shimi: "Ibuye ry'imfuruka rihamye" ryo guhuza n'ibidukikije bigoye
Ibintu bikoreshwa mu buvuzi bw'ibinyabutabire nk'ibikoresho byo gusukura n'amavuta bikunze gukoreshwa mu mahugurwa yo kugenzura indege. Ibikoresho bya aluminiyumu bishobora kwangirika, kandi ibikoresho by'icyuma bishobora kwangirika bitewe n'ubuziranenge bwa ogisijeni n'ingese. Granite igizwe ahanini n'amabuye y'agaciro nka quartz na feldspar. Ifite imiterere ihamye ya shimi, pH ishobora kwihanganira kuva kuri 1 kugeza kuri 14, kandi ishobora kurwanya kwangirika kw'ibintu bisanzwe bya shimi. Nta mvura ya iyoni y'icyuma igwa ku buso bwayo, bigatuma ahantu hasukuye haboneka ibidukikije kandi ikirinda amakosa yo gupima aterwa n'umwanda wa shimi.
V. Ubuziranenge mu gupima: "Ishingiro ryiza" ryo gupima neza
Binyuze mu ikoranabuhanga rigezweho cyane nka magnetorheological polishing na ion beam processing, granite platforms zishobora kugera ku buziranenge bwo gutunganya bwa ± 0.1μm/m kugira ngo habeho ubugari na Ra≤0.02μm kugira ngo habeho ubugari bw'ubuso, burenze kure ubw'ubw'ibyuma byashongeshejwe (± 1μm/m kugira ngo habeho ubugari) n'ubw'aluminiyumu (± 2μm/m kugira ngo habeho ubugari). Ubu buso bugezweho butanga uburyo bwo gushyiraho neza ibikoresho bipima neza n'ibikoresho bipima neza, byoroshya gupima ibice bitatu by'ibyuma bya moteri ku rwego rwa 0.1μm.
Mu bihe bikenewe cyane byo kugenzura ibyuma bya moteri mu kirere, urubuga rwa granite, rufite ibyiza byinshi mu kudahungabana k'ubushyuhe, kudahungabana, kudahindagurika kw'ibinyabutabire no gutunganya neza, byabaye amahitamo meza yo kwemeza ko igenzura rikora neza kandi ryizewe, bishyiraho urufatiro rukomeye rw'iterambere ry'inganda z'indege.
