Nyocha nke igwe ikuku ikuku nwere ihe dị oke elu chọrọ maka nkwụsi ike, izi ezi na ntụkwasị obi nke ikpo okwu. Tụnyere nyiwe nyocha ọdịnala dị ka nkedo ígwè na aluminom alloy, nyiwe granite na-egosi uru na-enweghị atụ n'ọtụtụ ihe ngosi igodo. ;
I. Thermal kwụsie ike: "Ọta eke" megide nnyonye anya okpomọkụ
Ọnụ ọgụgụ nke mgbasawanye okpomọkụ nke ikpo okwu nkedo bụ ihe dịka 10-12 × 10⁻⁶ / ℃, na nke aluminom alloys dị elu dị ka 23 × 10⁻⁶ / ℃. N'okpuru okpomọkụ nke na-arụ ọrụ nke ngwaọrụ nchọpụta ma ọ bụ mgbanwe na okpomọkụ gburugburu ebe obibi, nrụrụ akụkụ na-adịkarị mfe ime, na-eduga ná njehie nchọpụta. Ọnụ ọgụgụ nke mgbasawanye ọkụ nke ikpo okwu granite bụ naanị (4-8) × 10⁻⁶ / ℃. N'ime mgbanwe okpomọkụ nke ± 5 ℃, mgbanwe akụkụ nke ikpo okwu granite ogologo mita 1 bụ ihe na-erughị 0.04μm, nke fọrọ nke nta ka ọ bụrụ ileghara anya. Ngosipụta mgbasawanye ọkụ a dị ala dị ala na-enye ebe ntụaka kwụsiri ike maka akụrụngwa ziri ezi dị ka laser interferometers na igwe na-ahụ maka nha atọ, na-ezere ngbanwe nha nke agụba contours kpatara nrụrụ ọkụ. ;
Ii. Arụmọrụ mgbochi ịma jijiji: “Mgbochi dị mma” maka iwepụ nnyonye anya ịma jijiji
N'ebe a na-arụ ọrụ n'ichepụta ụgbọ elu, ụda gburugburu ebe obibi na-akpata site na ịrụ ọrụ igwe na mmegharị nke ndị ọrụ na-emekarị. Igwe ikpo okwu alloy aluminom enweghị nkwụsi ike zuru oke, yana igwe ihe nkedo nwere oke arụrụ arụ, na-eme ka o sie ike ịchekwa ịma jijiji nke ọma. Ọdịdị kristal dị oke n'ime ikpo okwu granite na-enye ya ọmarịcha njiri mara mma, yana oke 0.05-0.1, nke bụ okpukpu ise nke ígwè nkedo na okpukpu iri karịa nke aluminom alloy. Mgbe a na-ebufe mkpọtụ mpụga na ikpo okwu, ọ nwere ike belata ike ịma jijiji karịa 90% n'ime 0.3 sekọnd, hụ na akụrụngwa nchọpụta ka nwere ike wepụta data ziri ezi na gburugburu ebe na-ama jijiji. ;
Iii. Nkwụsi ike na iyi nguzogide: "Ebe siri ike" na-eme ka ọ dị ogologo oge
Mgbe ejiri ya mee ihe ruo oge ụfọdụ, ikpo okwu nkedo na-adịkarị mfe ike ọgwụgwụ, nke na-emetụta izi ezi ya. Aluminom alloy nyiwe nwere obere ike ike na adịghị mma na-eyi nguzogide, na-eme ka o sie ike iguzogide iji ngwa nyocha ọrụ dị arọ na-emekarị. Njupụta nke ikpo okwu granite ruru 2.6-2.8g / cm³, ike mkpakọ ya karịrị 200MPa, na ike Mohs bụ 6-7. Mgbe etinyere ibu dị arọ na esemokwu ogologo oge site na akụrụngwa nyocha agụba, ọ naghị adị mfe iyi ma ọ bụ nrụrụ. Data sitere na ụlọ ọrụ ụgbọ elu ụfọdụ na-egosi na mgbe ejiri ya na-aga n'ihu ruo afọ asatọ, a ka na-achịkwa mgbanwe nke ikpo okwu granite n'ime ± 0.1μm / m, ebe ikpo okwu nkedo dị mkpa ka a gbanwee ya mgbe naanị afọ atọ gasịrị. ;
Iv. Nkwụsi ike nke kemịkalụ: "Stable Cornerstone" maka imeghari na gburugburu gburugburu
A na-ejikarị reagents kemịkalụ dị ka ihe na-ehicha ihe na mmanu mmanu na ụlọ ọrụ nyocha ụgbọ elu. Aluminom alloy nyiwe na-adịkarị mfe corrosion, na nkedo ígwè ikpo okwu nwekwara ike na-emetụta nke ziri ezi n'ihi oxidation na nchara. Granite bụ ihe mejupụtara nke mineral dị ka quartz na feldspar. Ọ nwere akụrụngwa kemịkalụ kwụsiri ike, oke nnabata pH nke 1 ruo 14, ma nwee ike iguzogide nbibi nke ihe kemịkalụ nkịtị. Enweghị mmiri ozuzo metal ion n'elu ya, na-eme ka ebe nchọpụta dị ọcha na izere njehie nha nke mmetọ kemịkalụ kpatara. ;
V. Nhazi nke igwe: “Ideal Base” maka nha nkenke
Site ultra-nkenke teknụzụ dị ka magnetorheological polishing na ion beam nhazi, granite nyiwe nwere ike nweta nhazi ziri ezi nke ± 0.1μm / m maka flatness na Ra≤0.02μm maka elu roughness, dị nnọọ ukwuu nke nkedo ígwè nyiwe (± 1μm / m maka flatness) na aluminum alloy nyiwe (± 2μm / m). Ebe a dị elu dị elu na-enye ntụaka nrụnye ziri ezi maka ihe mmetụta dị elu na nyocha nke nha, na-eme ka a mata ihe nleba anya nke akụkụ atọ nke eriri igwe ikuku na ọkwa 0.1μm. ;
N'ihe dị elu na-achọsi ike nke nyocha nke ikuku engine, ikpo okwu granite, na uru ha zuru oke na nkwụsi ike nke okpomọkụ, nguzogide vibration, nkwụsi ike, nkwụsi ike nke kemịkal na nhazi nhazi, aghọwo nhọrọ kachasị mma iji hụ na nyocha nke ziri ezi na ntụkwasị obi, na-etinye ntọala siri ike maka mmepe dị elu nke mmepụta ụgbọ elu.
