Ni ubuhe buryo bukoreshwa mu gukora granite igororotse kandi ni ubuhe buryo bushoboka bwo kugerwaho?

I. Inzira yumusaruro wa Granite Igororotse
Kugenzura ibikoresho bibisi no gukata
Ibipimo byo gutoranya ibikoresho: Hitamo granite yo mu rwego rwo hejuru ifite ubucucike bwa ≥2.7g / cm³ hamwe n’igipimo cyo kwinjiza amazi ya <0.1% (nka "Jinan Green" ukomoka i Shandong na "Umusenyi wa Zahabu wirabura" ukomoka mu Buhinde). Ibice bya minerval bigomba kuba bimwe (quartz ibice ≤2mm), bitarimo ibice na pore, kandi amabuye yihishe agomba gukurwaho hakoreshejwe X-ray.
Gukata bikabije: Koresha umuzenguruko wa diyama kugirango ugabanye ubusa mu buso bunini bwa 5-10mm kurenza ubunini bwibicuruzwa byarangiye. Ikosa rya tekinike yo gukata rigomba kugenzurwa muri ± 0.5mm.
2. Kuvura gusaza
Gusaza bisanzwe: Shira umubiri wicyatsi mumezi 6 kugeza 12. Binyuze mu itandukaniro ryubushyuhe hagati yumunsi nijoro nimpinduka zubushuhe, hejuru ya 90% byimyitwarire yimbere irekurwa kugirango hirindwe ihinduka mubyiciro byanyuma.
Gusaza kwubukorikori (kubushake): Bamwe mubakora bakoresha itanura ryubushyuhe burigihe (100-150 ℃) mumasaha 24 kugirango byihute kurekura imihangayiko, bikwiranye nibyihutirwa, ariko ingaruka ziri hasi gato ugereranije no gusaza bisanzwe.
3. Gusya bikabije no gutunganya ubuso
Gusya bikabije no gushushanya: Koresha uruziga rwa diyama 200-400 rusya kugirango usya ubusa, ukureho imirongo ikata, ukosore uburinganire kuva ± 0.5mm kugeza ± 0.1mm / m (100μm / m), hanyuma umenye ubuso bwerekanwe.
Kuvura ubuso budakorwa: Chamfer cyangwa ikote kuruhande no hepfo (nko gutera irangi rirwanya ingese) kugirango wirinde kumeneka no kwaguka kwinshi.

4. Gusya neza (inzira yibanze)
Gusimbuka neza kugerwaho binyuze mu gusya kurwego, bigabanijwemo ibyiciro bitatu:

Gusya bikabije: Koresha 400-800 mesh abrasives (silicon carbide cyangwa micro-powder ya diyama) ufatanije na granite yo gusya kugirango ukosore uburinganire bwa mm 10μm / m, hamwe n'ubuso bwa Ra≤0.8μm.
Gusya neza: Muguhindura 1200-2000 mesh abrasives hanyuma ugahuza nurwego rwa elegitoronike (ubunyangamugayo ± 1μm / m) kugirango ukurikirane igihe nyacyo, uburinganire bwarahinduwe kugeza kuri ± 3μm / m, naho ubukana bwa Ra ni ≤0.4μm.
Gusya cyane-urufunguzo (urufunguzo rwibicuruzwa bisobanutse neza): Ukoresheje W-W5 yo mu rwego rwa micro-ifu (ingano ya 5-10μm) hamwe n’amazi yo mu bwoko bwa chimique, binyuze mu bikorwa bibiri bya "gusya imashini + kwangirika kwa chimique", uburinganire bwanyuma bushobora kugera kuri mm 1μm / m, hamwe nuburinganire bwa Ra≤0.2μm.
5. Gutahura neza no gukosora
Ibikoresho byo gutahura: Lazeri interferometero (ubunyangamugayo ± 0.1μm) hamwe nurwego rwa elegitoronike (imyanzuro 0.001mm / m) ikoreshwa mugukora ibishoboka byose kugirango igaragaze neza kandi igororotse, no gushushanya ikarita yo gukwirakwiza amakosa.
Gufunga-gufunga gukosora: Ukurikije amakuru yo gutahura, gusya kwinyongera byaho bikorerwa ahantu hahanamye cyane hifashishijwe imashini isya CNC kugeza igihe ikosa ryuzuye rigenzurwa mugihe cyagenwe.
6. Kurinda ubuso no gupakira
Ubuvuzi bwo gukingira: Shira kuri nano-nini ya silika yuzuye (5-10 mm yuburebure) hejuru yerekana, hanyuma ushyireho igishashara kirwanya ibishashara hejuru yumurimo udakora kugirango wirinde kwinjiza amazi cyangwa okiside mugihe kirekire.
Gupakira neza: Bipakiye mumashanyarazi yimbaho ​​zidafite ibiti hamwe na desiccants. Mugihe cyo gutwara, itandukaniro ryubushyuhe rigenzurwa muri ± 5 ℃ kugirango wirinde kwitonda neza guterwa no kunyeganyega.
Ii. Icyiciro Cyiza Cyiza Cyambere Inganda
Ubusobanuro bwa granite bugororotse bushingiye ku kwibeshya nkibipimo fatizo. Ukurikije ibipimo byigihugu (GB / T 4977-2018) hamwe nu rwego mpuzamahanga (ISO 2768-2), amanota yukuri hamwe nibipimo bihuye nibi bikurikira:

Laboratoire zo hejuru zishobora kugera ku kuri:
Binyuze mu buhanga bwo gusya bwa nano (nka polne ya magneorheologiya no guhindura ion beam), uburinganire bwibicuruzwa bimwe na bimwe byo mu rwego rwo hejuru birashobora gucika kugeza kuri ± 0.5μm / m (ni ukuvuga, ikosa kuri metero imwe ntirirenga micrometero 0.5), ryegereye indege ya optique yo mu rwego rwo hejuru. Zikoreshwa cyane cyane mubintu bisobanutse neza nk'ikirere n'ikirere cya metero.

Iii. Kugereranya Ibintu bigira ingaruka ku kuri

Incamake: Ubusobanuro buhanitse bwa granite bugororotse bushingiye kugenzura byuzuye "ibikoresho byibanze byujuje ubuziranenge + ultra-ndende gusaza + byoroheje byo gusya + ibidukikije bikaze", muri byo inzira yo gusya ni yo ntandaro yo gutera imbere mu buryo bwuzuye. Hamwe niterambere rya tekinoroji ya nanofabrica, ubusobanuro bwayo bugenda butera imbere buhoro buhoro kugera kurwego rwa sub-micron kandi byahindutse igikoresho kidasimburwa mubijyanye ninganda zo mu rwego rwo hejuru.
