Kwicandelo lobunjineli bokuchaneka kunye ne-metrology, izinto ezichanekileyo zegranite—ezifana neepleyiti zomphezulu, iziseko zoomatshini, kunye neetafile ze-optical—zihlonitshwa ngenxa yokuzinza kwazo okugqwesileyo, ubulukhuni, kunye nokumelana nokugqwala. Icandelo legranite elisemgangathweni ophezulu, xa likhathalelwe kakuhle, linokugcina ukulinganiswa kwalo kunye nokuthe tyaba amashumi eminyaka, lisebenza njengesiseko esingagungqiyo sokulinganisa kwakho okubalulekileyo. Nangona kunjalo, negranite ehlala ixesha elide ayinakukhuseleka kwiimpembelelo ezincinci zendalo kunye nokusetyenziswa kwayo. Ukugcina ukulinganiswa kwexesha elide akusiyonto iyenzeka kube kanye; yinkqubo eqhubekayo efuna ukuqonda okunzulu kolawulo lwendalo, ukuphathwa ngononophelo, kunye nenkqubo yokulungisa ngokukhawuleza.
Ukuqonda iSiseko seNdalo
Utshaba olukhulu lokulinganiswa kwexesha elide asikuko ukuguguleka kwemihla ngemihla, kodwa kukusingqongileyo okungalawulwayo. Ukuqinisekisa ukuba izinto zakho zegranite zigcina ukuchaneka kwazo kwinqanaba le-micron, kufuneka uqale ubeke isiseko esizinzileyo somzimba.
Ubushushu yeyona nto ibalulekileyo. I-granite ine-coefficient ephantsi kakhulu yokwandiswa kobushushu, kodwa ayisiyo-zero. Kumanqanaba aphezulu okuchaneka, izinto kufuneka zigcinwe kwilebhu ye-metrology elawulwa bubushushu, egcinwa kwi-20°C engaguqukiyo (±2°C). Ukutshintsha kobushushu ngequbuliso okanye ukuvezwa ngqo elangeni, kwiindawo zomoya opholileyo, kunye nemibhobho yokufudumeza kunokubangela i-gradients yobushushu yendawo. Ezi gradients zenza uxinzelelo lwangaphakathi ngaphakathi kwelitye, okukhokelela kwi-micro-deformations yexeshana kodwa ebalulekileyo eyonakalisa ukuchaneka kokulinganisa. Ngaphezu koko, izinto zokusebenza ezinkulu okanye iibhloko ze-gauge kufuneka zivunyelwe ukuba zivumelane nomphezulu we-granite iiyure ezininzi ngaphambi kokulinganisa ukuthintela ukudluliselwa kobushushu kwiziphumo ezigobileyo.
Okubaluleke ngokulinganayo sisiseko sofakelo. Inxalenye yegranite izinzile kuphela njengoko ihleli kuyo. Kufuneka ibekwe kwisiseko esiqinileyo, esingenazingcangcazelo. Kwiimeko ezichanekileyo, oku kudla ngokuthetha ukusebenzisa ii-active okanye pneumatic vibration isolation pads ukuze kuhlukaniswe igranite kwiingcangcazelo zomgangatho ezibangelwa zizixhobo ezikufutshane, ii-forklifts, okanye nokuhamba ngeenyawo. Xa ufaka ipleyiti enkulu yomphezulu, inkxaso efanelekileyo ayinakuxoxiswana ngayo. Kufuneka ihlale kwinkqubo yokuxhasa enamaphuzu amathathu okanye amahlanu (ngesiqhelo amanqaku amathathu aphambili enza unxantathu we-isosceles kunye namanqaku amabini ancedisayo). Olu lungiselelo luthintela uxinzelelo lwangaphakathi kunye "nokushukuma," ukuqinisekisa ukuba ipleyiti ihlala kwimeko yayo yendalo, engenazingcazelo. Emva kokulinganisa kokuqala, kucetyiswa kakhulu ukuba ivumele inxenye ihlale ingaphazanyiswa iiyure ezili-12 ukuya kwezingama-24 ukuvumela naziphi na izingcazelo ezishiyekileyo ukuba ziphele ngaphambi kokuthatha ukufundwa kokugqibela kokulinganisa.
Iindlela ezilungileyo zokuphatha imihla ngemihla kunye nokusebenza
Nje ukuba imeko-bume ilawulwe, ixesha elide lokulinganiswa kwegranite yakho lixhomekeke kakhulu kwindlela ephathwa ngayo kwimisebenzi yemihla ngemihla. Umphezulu wepleyiti yegranite yeyona nto ixabisekileyo kuyo, kwaye ukuyikhusela ekonakaleni komzimba kubaluleke kakhulu.
Soloko uqinisekisa ukuba umphezulu wegranite ucocekile kakuhle ngaphambi nasemva kokusetyenziswa. Uthuli, iitships zesinyithi, kunye neengceba ezirhabaxa zezona zinto ziphambili zokukrweleka komphezulu. Sebenzisa ilaphu elithambileyo, elingena-lint elimanziswe kancinci ngesicoci se-pH esingathathi cala okanye i-alcohol ecocekileyo ephezulu ukuze usule umphezulu. Ziphephe izinyibilikisi zamakhemikhali eziqatha okanye izisombululo ze-alkaline, njengoko zinokutshabalalisa umphezulu welitye kancinci ngokuhamba kwexesha. Xa ubeka izinto zokusebenza kwipleyiti, ungaze uzishelele okanye uzirhuqe. Endaweni yoko, ziphakamise uze uzibeke phantsi kancinci. Kwizinto ezinzima, sebenzisa ii-jacks okanye ii-hoists ezihlengahlengiswayo ukusasaza ubunzima ngokulinganayo kwaye uthintele imithwalo exineneyo enokubangela uxinzelelo okanye ukuqhekeka kwendawo.
Kubalulekile kwakhona ukukhumbula ukuba ipleyiti yomphezulu wegranite ayiyontoni. Ayisiyo ibhentshi yokusebenzela, i-anvil, okanye indawo yezinye izixhobo. Ungaze usebenzise umphezulu ekubhaleni, ekubetheni ngesando, okanye njengesiseko semisebenzi enzima yoomatshini enokubangela umonakalo. Ukongeza, izinto zokusebenza zemagnethi kufuneka zisuswe kumbane ngaphambi kokuba zibekwe kwipleyiti. Imagnethi eseleyo inokutsala amasuntswana esinyithi acolekileyo emoyeni, anokusebenza njengesiqholo phantsi kwenxalenye ehambayo, ekrwela kancinci umphezulu ochanekileyo.
Ukugcinwa Okusebenzayo kunye noHlaziyo oluHlaziyiweyo rhoqo
Nokuba kukho ulawulo olugqibeleleyo lokusingqongileyo kunye nokuphathwa ngobunono, ukulinganiswa kwexesha elide kufuna ishedyuli yokugcinwa ecwangcisiweyo. I-Granite yinto yendalo, kwaye kwiminyaka emininzi, inokuhlangabezana notshintsho oluncinci ngenxa yokuqhekeka okanye ukuhla kwezinto. Ke ngoko, ukuthembela kuphela kukulinganiswa kokuqala kwefektri kuyingozi engenakuthwalwa yilebhu yokuchaneka.
Sebenzisa inkqubo yokuqinisekisa elandelelanayo. Imihla ngemihla okanye ngeveki, abaqhubi kufuneka benze uhlolo olukhawulezileyo lokubona umonakalo womphezulu kunye nokujonga ubume obuthe tyaba besebenzisa inqanaba lomoya ochanekileyo okanye umphetho othe tye olinganisiweyo. Oku kunceda ekubambeni naziphi na iingxaki ezikhawulezileyo okanye utshintsho olukhulu.
Ukuze ulungelelanise ixesha elide ngokwenene, cwangcisa uhlengahlengiso olusesikweni rhoqo, rhoqo emva kweenyanga ezi-6 ukuya kwezili-12, kuxhomekeke kwinani lokusetyenziswa kunye namanqanaba okunyamezela afunekayo. Le nkqubo kufuneka iqhutywe ziingcali ze-metrology ezifanelekileyo zisebenzisa izixhobo ezilandelekayo, ezifana nezixhobo ze-elektroniki ezinesisombululo esiphezulu okanye ii-laser interferometers. Ngexesha lale nkqubo, wonke umphezulu uyaskenwa (ngokuqhelekileyo kwi-grid okanye "ngenkwenkwezi") ukuvelisa imephu epheleleyo ye-topographical yepleyiti. Ukuba kufunyenwe ukuphambuka okuncinci, iingcali ezinobuchule zihlala zenza i-lapping okanye i-scrap yokulungisa kwindawo ukuze zibuyisele umphezulu kwi-DIN yazo yokuqala okanye kwi-ISO tolerance grade.
Ngokulawula ngokungqongqo okusingqongileyo, ukunyanzelisa imigaqo yokuphatha engqongqo, nokuzibophelela kwishedyuli yokulungiswa kwakhona kobuchwephesha, uqinisekisa ukuba izinto zakho ezichanekileyo zegranite zihlala ziyindlela ethembekileyo. Olu kuzinikela alukhuseli nje kuphela utyalo-mali lwakho lwemali kodwa, okubaluleke ngakumbi, kuqinisekisa ukuthembeka kunye nokuthembeka kwayo yonke imilinganiselo eyenziwa liqela lakho.
