Hari ikintu gisekeje mu kuba bimwe mu bikoresho bya semiconductor bigezweho, sisitemu zo gushyiramo imirasire ya laser, n'imashini zipima (CMMs) ku isi bishingira ku rufatiro rwashinzwe mu myaka igera kuri miliyoni 300 ishize mu Isi. Granite - ibuye rimwe ry'umukara rikora imisozi n'ibihanamanga byo ku nkombe - ryabaye ibikoresho by'ingenzi ku nyubako z'ibanze n'ubuso bw'ibikoresho byo gukora ibikoresho bigezweho. Ariko granite yose si ko ingana. Kandi gusobanukirwa impamvu inzobere zikomeza kugaruka kuri iri buye rya kera, aho guhindura ibintu bigezweho cyangwa ibyuma, bigaragaza ikintu cy'ingenzi kuri fiziki y'ubuziranenge ubwayo.
Ikibazo ku byuma: Ubushyuhe n'ubushyuhe
Mbere yo gusuzuma ibyiza bya granite, birafasha gusobanukirwa icyo iri gusimbuza - n'impamvu iyo simbuza yari ngombwa.
Mu kinyejana cya 20, ubuso bupima neza n'ibice by'imashini byakozwe mu byuma cyangwa ibyuma. Ibi bikoresho birakomeye mu buryo bwa mashini, bishobora kwihanganira ibyuma cyane, kandi abahanga babyumva neza. Ariko ku gipimo cya mikorometero na nanometero nk'uko inganda zigezweho zibisaba, imiterere ibiri y'ibyuma bya feri ihinduka ibibazo bikomeye: kwaguka k'ubushyuhe na hysteresis ya mashini.
Icyuma gifite igipimo cyo kwaguka k'ubushyuhe (CTE) kingana na 11–13 × 10⁻⁶ /°C. Ibi bivuze ko icyuma cya metero 1 cyaguka cyangwa kigabanyukaho mikorometero 11–13 kuri buri mpinduka ya 1°C mu bushyuhe. Mu ikorwa aho ubushyuhe buhinduka na 2–3°C mu gihe cy'umunsi, igice cy'icyuma gishobora guhinduka mu buryo bungana na mikorometero 25–40 - ikosa rigabanya burundu ubushobozi bwo kwihanganira mikorometero nke busabwa na precision optics, semiconductor lithography, cyangwa CMM calibration work.
Ibyuma bikora neza mu bijyanye no kugabanya umuvuduko w’imashini, ariko bifite ikibazo kimwe cy’ubushyuhe. Byongeye kandi, icyuma n’icyuma bihura n’ingaruka za rukuruzi, kandi uko igihe kigenda gihita, bigabanya umuvuduko w’imbere mu mubiri - ikintu aho imihangayiko isigaye ituruka ku gucukura cyangwa gukora imashini bya mbere irekura buhoro buhoro, bigatuma igice kigenda gihindagurika mu buryo butunguranye mu mezi cyangwa imyaka.
Imiterere y'Ibintu bya Granite: Incamake y'Ubwubatsi
Granite ni ibuye ry’umukara ryinjiramo cyane rigizwe ahanini na quartz (SiO₂), feldspar (KAlSi₃O₈, NaAlSi₃O₈, CaAl₂Si₂O₈), n’amabuye y’agaciro ya mica cyangwa amphibole. Imiterere yaryo ikomoka ku myaka miliyoni y’ubushyuhe bw’imyaka myinshi mu gihe cy’umuvuduko ukabije, bigatuma habaho imiterere y’ibinyampeke bifatanye biyiha imiterere myinshi myiza mu gukoresha neza ubuhanga.
1. Koreyi nkeya yo kwagura ubushyuhe
Granite y'umukara yo mu rwego rwo hejuru ubusanzwe ifite CTE ya 6–8 × 10⁻⁶ /°C - hafi kimwe cya kabiri cy'icyuma. Mu icungamutungo rigenzurwa rifata ± 0.5°C, igice cya granite cya metero 1 kizimuka mu buryo bwa mikorometero 3–4 gusa. Ibi si iterambere ryiyongera gusa; ku rugero rwo hasi rwa mikorometero, kugabanya ikosa ry'ubushyuhe hagati bishobora gusobanura itandukaniro hagati y'igipimo cyemewe cyangwa kidafite agaciro.
Granite y'umukara yo mu rwego rwo hejuru — nka granite y'umukara ya ZHHIMG® ikoreshwa mu bice by'ubuhanga bya ZHONGHUI Group, igera ku bucucike bwa kg 3.100/m³ — igaragaza ubushyuhe buhamye cyane bitewe n'ubucucike bwayo bwinshi bwa kristale n'ubucucike buke. Uko imiterere y'ibinyampeke irushaho kuba nini, ni ko umwuka n'ubushuhe bike bishobora kwinjiza, kandi uko ubushyuhe burushaho gukomera no ku buryo buhamye uko igihe kigenda gihita birushaho kuba byiza.
2. Kudashobora kwemerera gukoresha Magnetike ntarengwa
Granite ntabwo ikoresha ingufu za rukuruzi. Iyi miterere ni ingenzi cyane mu nganda zikora ibikoresho bya semiconductor aho imbaraga za rukuruzi zituruka kuri moteri, actuators, na sensors zishobora guteza amakosa mu gushyira ibintu mu bice bya ferromagnetic. Imiterere ya granite ntabwo ihinduka na gato n’imbaraga za rukuruzi zo hanze, bigatuma ziba ishingiro ryiza rya Hall-effect sensors, linear encoders, na systeme za rukuruzi.
3. Gutuma umuntu adashobora gutembera neza mu gihe cyo gutembera
Imiterere ya kristu ya Granite ifatanye iha imiterere myiza yo kudakoresha imivuduko - iruta cyane icyuma gishongeshejwe cyangwa icyuma. Mu mibare, granite ikunze kugira ingano y'umuvuduko ikubye gatatu kugeza kuri gatanu ugereranije n'icyuma gishongeshejwe.sisitemu za laser zigezweho(laser ya femtosecond cyangwa picosecond), CMM, n'ibikoresho byo kugenzura urumuri, bivuze ko imitingito yo hasi mu kirere - ituruka kuri sisitemu za HVAC, urujya n'uruza rw'amaguru, cyangwa imashini zegereye - igabanuka mbere yuko ishobora kubangamira uburyo bwo gupima cyangwa gutunganya.
4. Ingufu nyinshi zo gukanda hamwe no guhagarara neza mu buryo bungana
Ubusanzwe imbaraga zo gukandagira za Granite ziba hagati ya MPa 100 na 300 bitewe n'imiterere yazo. Icy'ingenzi kurushaho, ukurikije imiterere y'ubuhanga, granite nta kintu na kimwe igaragaraho iyo iremereye cyane. Ibyuma ndetse n'ibindi bikoresho by'ubuhanga bizagenda bihinduka buhoro buhoro iyo iremereye cyane mu gihe cy'imyaka myinshi ikoreshwa. Granite, imaze imyaka amagana ikoreshwa mu gitutu gikomeye cya geologiya, yarangije iki gikorwa. Isahani y'ubuso bwa granite ifatanye neza izakomeza kuba ndende kugeza ku gipimo cyayo mu gihe cy'imyaka ibarirwa muri za mirongo ikoreshwa, mu gihe ifashwe neza.
5. Ubudahangarwa bw'imiti n'ubukonje
Granite ntabwo irwanya imiti myinshi, amavuta, n'ibindi bikoresho bikonjesha bikorerwa mu nganda mu buryo bunoze. Ntishobora kwangirika, gushonga cyangwa ngo igire ingaruka ku bikoresho bisukura bikoreshwa mu byuma bipima imiterere y'ibintu cyangwa ibyumba by'ikoranabuhanga. Ibi bigira uruhare runini mu kumara igihe kirekire kw'ibice bya granite ugereranije n'ibindi bikoresho by'icyuma bidapfutse.
Granite yose si imwe: Uruhare rw'ingenzi mu guhitamo ibikoresho
Igitekerezo kibi gikunze kugaragara mu nganda ni uko granite ari granite - ko igice icyo ari cyo cyose cy'uru rutare kizakora kimwe iyo gikozwe mu mashini kandi gikozwe ku buryo bungana. Ibi ntabwo ari byo rwose, kandi ingaruka zo guhitamo ibikoresho bidakomeye zishobora kwangiza inzira yose yo gukora neza.
Marble vs. granite ni cyo kintu cy'ingenzi cyane. Marble ni ibuye rya metamorphic rigizwe ahanini na kalisiyumu karubone (CaCO₃). Riroroshye (ubukana bwa Mohs 3–4 ugereranyije na granite 6–7), rirushaho kugira imyenge, rishobora kwangirika cyane mu bushyuhe, kandi ritahindagurika cyane mu gihe cy’umutwaro uhoraho. Bamwe mu batanga ibicuruzwa bihendutse basimbuza marble granite mu masahani yo hejuru n’ibipimo, bishingikiriza ku baguzi kudapima ibikoresho ku giti cyabo. Iyi gahunda si ukugabanya ikiguzi gusa - ni uburiganya bw’ubuhanga bubangamira ubuziranenge bw’ibipimo byose bikorwa hakoreshejwe ibyo bikoresho.
Granite y'umukara ugereranije na granite y'umukara ni itandukaniro rikomeye. Granite y'umukara - mu by'ukuri ari anorthosite cyangwa gabbro mu byiciro by'ubutaka - ubusanzwe ifite ubucucike bwinshi, imiterere y'ibinyampeke byiza, kandi ifite porosity nkeya kurusha granite y'umukara isanzwe. Ibi bivuze ko ubushobozi bwo kurangiza neza ubuso (agaciro gake k'ubushyuhe bwa Ra), kudahinduka cyane mu ngero, no gukora neza mu buryo buhoraho. Ubucucike bwinshi cyane bwa granite y'umukara ya premium (igera kuri 3,100 kg / m³) bivuze ko hari ubucucike buke mu bikoresho - kandi ubucucike buke bivuze ko hari amahirwe make yo kuba ubushuhe cyangwa ubushyuhe bufatiwe mu mazi bushobora gutuma habaho gupima ibintu bidasobanutse neza.
Gushaka isoko ry’ubutaka n’imiterere ya geologiya nabyo ni ingenzi. Si amabuye yose acukurwamo amabuye afite imiterere imwe ya kristu cyangwa imiterere imwe ya chimique. Abatanga granite b’abahanga mu by’ubuziranenge bakora isuzuma ry’ibikoresho - gupima ubucucike, ubukana, ingano y’ibinyampeke, na CTE mbere yuko hatangira gutunganywa - kugira ngo barebe ko buri gice cy’amabuye mashya cyujuje ibisabwa. Uku kugenzura ubuziranenge kugaragara ku mukoresha wa nyuma ariko ni ingenzi ku buryo ibicuruzwa birangira bihinduka.
Uburyo bwo gukora: Kuva ku ibuye risanzwe kugeza ku rwego rwa nanometero
Ndetse na granite nziza cyane, iyo icukuwe kandi iciwe neza, ntaho ihuriye n’ibipimo by’ubuziranenge. Kugira ngo umuntu agere ku buremere bw’ubugari busabwa ku masahani y’ubuso ya 00 (ubugari bwa ± 1.0 μm hejuru ya 400mm × 400mm kuri DIN 876), imiterere y’ubugari buhamye (ubugari buri muri 1 μm), cyangwa ubuso bwo gushyiraho ibikoresho bya semiconductor bisaba gukora no kugenzura mu byiciro byinshi mu gihe cy’ibyumweru byinshi.
Gukata no gushimangira neza ni byo bibanza. Ibice by'ibanze bicibwa ku bunini bungana kandi bikarekwa bihamye - rimwe na rimwe mu gihe cy'amezi menshi - mu buryo bugenzurwa. Ibi bituma ibisigazwa by'imbere biva mu gucukura no gukata birekurwa mbere yuko imashini ikora neza itangira. Gusimbuka iyi ntambwe bivuze ko ibuye rishobora gukomeza kugabanya stress nyuma yo gukora, bigahindura buhoro buhoro ubuso bwari buhagaze ubwo ryavaga mu ruganda.
Gusya neza bikurikizaho, hakoreshejwe imashini nini zisya hejuru kugira ngo igice cyazo kigere kuri mikorometero icumi z’ibipimo bya nyuma. Imashini zisya za CNC zigezweho zifite amapine ya diyama cyangwa CBN zishobora kugera kuri iki cyiciro neza. Ariko, guhitamo ipine yo gusya, umuvuduko wo kuyigaburira, n'icyuma gikonjesha byose ni ingenzi cyane - ibipimo bitari byo bishobora kwangiza ubuso cyangwa imbaraga z'ubushyuhe ziterwa no gusya bikabangamira ihindagurika ry'amazi nyuma yo gusya.
Gutera no gukurura intoki niho ubuhanga nyakuri bwo gukora granite neza buherereye. Inzira zikoresha ikoranabuhanga zishobora gutuma ubuso bugera kuri mikorometero 5-10 uvuye ku buryo bugaragara, ariko kugera ku buryo bugaragara bwa 00 cyangwa grade-K (bikunze kwitwa grade-laboratory) - bipimirwa mu bice bya mikorometero - bisaba ubuhanga bwo gutera. Abanyabukorikori b'inararibonye bakoresha plaque zo hejuru, ibyuma bito by'urumuri, n'ubuhanga bwo kohereza ubururu bwa Prussia byakozwe mu binyejana byinshi by'imyitozo yo gupima kugira ngo bamenye ahantu hirengeye ku buso no kubikuraho neza. Imashini ikomeye ifite uburambe bw'imyaka irenga 30 ikuramo ubushobozi bwo gukoraho butuma bumva ibintu bikuweho ku rwego rwa mikorometero 1-2 - ubushobozi nta sisitemu ikora ishobora kwigana byuzuye.
Igipimo cya nyuma n'icyemezo bikoresha ibikoresho bishobora gukurikiranwa hakurikijwe amahame y'ibipimo by'igihugu n'amahanga. Interferometer za laser, urwego rw'ikoranabuhanga (nk'ibyakozwe na WYLER yo mu Busuwisi), na profilometers zifite ubushobozi bwo hejuru zemeza ko igice cyarangiye cyujuje ubugari bwacyo, ubugari bwacyo, n'ubuso bwacyo mbere yuko kiva mu ruganda. Buri gikoresho cyo gupima gikoreshwa mu kwemeza ibicuruzwa kigomba kwitwaza icyemezo cyo gupima gishobora gukurikiranwa binyuze mu mugozi utaracikamo ibice kikajyanwa mu kigo cy'igihugu cy'ibipimo by'ikirere.
Porogaramu zisaba ihindagurika ry'urwego rwa Granite
Gusobanukirwa impamvu granite ikoreshwa biragaragara cyane iyo urebye uburyo ikoreshwamo aho imiterere yayo yihariye idasimburwa:
Ifotolithography ya semiconductor — aho imiterere y’uruziga rwapimwe muri nanometero igomba gushyirwa ahantu hashobora gusubiramo nanometero — bisaba imiterere y’ibanze ya granite idahindura ingano uko sisitemu ishyuha mu gihe cyo gukora. Sisitemu zo mu cyiciro zimura wafer za silicon munsi y’ibikoresho byo kugaragaraho akenshi ziba zubatswe ku buso bwa granite bunoze.
Imashini zo gupima (CMMs) — zikoreshwa mu nganda z’indege, imodoka, n’ibikoresho by’ikoranabuhanga kugira ngo zemeze ko ibice byakozwe mu mashini byujuje ibisabwa mu gushushanya — zishingira ku masahani y’ubuso bwa granite nk’ikigereranyo cyazo. Ubugari bw’ubu buso bw’ikigereranyo ni wo musingi w’aho ibipimo byose bya CMM byubakirwa.
Sisitemu za laser za Femtosecond na picosecond — zikoreshwa mu gukora micromachine, ophthalmology, no mu bushakashatsi bwa siyansi — zisaba inzira z'imirasire y'urumuri iguma ihamye kugeza ku bice by'uburebure bw'urumuri. Guhindagurika kw'imirasire ya Granite no kudahindagurika kw'ubushyuhe bituma iba ahantu heza ho gushyiramo ameza y'urumuri n'amateraniro y'imirasire ya laser.
Ibyiciro by'umwuka bikoresha umurongo ugororotse — bikoresha agace gato k'umwuka urimo umuvuduko kugira ngo bikore ingendo zidahindagurika — bisaba ubuso bw'ubuyobozi bwa granite buringaniye kugeza kuri nanometero magana make ugereranyije n'uburebure bwabwo bwose bw'urugendo. Guhinduka kose mu buso bw'ubuyobozi bigaragazwa nk'ikosa ryo gushyira mu mwanya ikintu kigenda.
Umwanzuro: Ibikoresho bya kera, Ikoreshwa ry'ejo hazaza
Itsinda rya Granite mu gukora ibintu bigezweho cyane si uguhora wibuka ibintu byashize cyangwa kutishimira. Igaragaza isuzuma ry’ibikoresho biboneka mu buryo bwumvikana ugereranyije n’ibisabwa cyane n’ibipimo bya sub-micron na nanometer. Kwaguka kwayo mu bushyuhe buke, ubushobozi bwo kudakoresha ingufu za rukuruzi, kudatuma ibintu bihindagurika neza, no kudahindagurika mu buryo bw’igihe kirekire biyiha uruvange rw’imiterere idafite aho ihuriye n’uburyo ikora.
Icyahindutse si ibikoresho ubwabyo ahubwo ni amahame akoreshwa mu gutunganya no kwemeza. Itandukaniro riri hagati y'ibuye n'ikibaho cyemewe cya granite cy'ubuso bwemewe na grade-00 - itandukaniro riri hagati y'aho amabuye acukurwa n'ibikoresho bya semiconductor - riri mu buryo bunoze bw'imikorere y'inganda, uburyo bwiza bw'ubuziranenge buyikikije, n'ubuhanga bw'abakora uwo murimo.
Ku bahanga bagena ibikoresho by'ibanze by'ibikoresho bigezweho cyane, gusobanukirwa iri tandukaniro si imyitozo yo mu rwego rw'amasomo. Ni wo musingi w'ishingiro ry'ubuziranenge bw'ibipimo - bityo n'ubuziranenge bw'inganda - bwubakirwaho.
