Xa iinjineli kunye neengcali zemetro zikhetha iqonga legranite elichanekileyo lokulinganisa imisebenzi enzima kunye nokuhlanganisa, isigqibo sokugqibela sihlala sigxile kwipharamitha ebonakala ilula: ubukhulu bayo. Sekunjalo, ubukhulu bepleyiti yomphezulu wegranite bungaphezulu kakhulu kunobukhulu obulula—yinto esisiseko elawula amandla ayo omthwalo, ukumelana nokungcangcazela, kwaye ekugqibeleni, amandla ayo okugcina uzinzo lwexesha elide.
Kwizicelo ezichanekileyo kakhulu, ubukhulu abukhethwa ngokungacwangciswanga; lubalo lobunjineli olubalulekileyo olusekelwe kwimigangatho esele imiselwe kunye nemigaqo eqinileyo yokuphambuka koomatshini.
Umgangatho woBunjineli oBusemva kokuQina ukuQina
Injongo ephambili yeqonga elichanekileyo kukusebenza njengeplani yesalathiso esithe tyaba nesingashukumiyo. Ke ngoko, ubukhulu bepleyiti yomphezulu wegranite bubalwa ngokukodwa ukuqinisekisa ukuba phantsi komthwalo wayo omkhulu olindelweyo, ukuthamba kwepleyiti iyonke kuhlala ngaphakathi komgangatho wayo omiselweyo wokunyamezela (umz., iGrade AA, A, okanye B).
Olu lwakhiwo lulandela izikhokelo eziphambili zoshishino, ezifana nomgangatho we-ASME B89.3.7. Umgaqo ophambili ekumiselweni kobukhulu kukunciphisa ukujika okanye ukugoba. Sibala ubukhulu obufunekayo ngokuqwalasela iipropati zegranite—ingakumbi iYoung's Modulus of Elasticity yayo (umlinganiselo wokuqina)—kunye nobukhulu bepleyiti iyonke kunye nomthwalo olindelekileyo.
Umgangatho weGunya loMthwalo
Umgangatho we-ASME owamkelweyo ngokubanzi uqhagamshela ubukhulu ngokuthe ngqo kumthamo wokuthwala umthwalo wepleyiti usebenzisa umda othile wokhuseleko:
Umthetho Wozinzo: Iqonga legranite kufuneka libe likhulu ngokwaneleyo ukuxhasa umthwalo oqhelekileyo osetyenziswa embindini wepleyiti, ngaphandle kokuphambukisa ipleyiti kuyo nayiphi na i-diagonal ngaphezu kwesiqingatha sokunyamezela kwayo ukuthamba.
Le mfuneko iqinisekisa ukuba ubukhulu bubonelela ngokuqina okufunekayo ukuze kutsalwe ubunzima obusetyenzisiweyo ngelixa kugcinwa ukuchaneka kwe-sub-micron. Kwiqonga elikhulu okanye elinomthwalo omninzi, ubukhulu obufunekayo buyanda kakhulu ukuze kuthintelwe umzuzu wokugoba ophezulu.
Ubukhulu: I-Triple Factor kwi-Precision Zinzo
Ubukhulu beqonga busebenza njengesandisi-lizwi ngqo sobume balo. Ipleyiti etyebileyo inika iingenelo ezintathu ezibalulekileyo ezidityanisiweyo ukuze kubekho ukulinganiswa okuchanekileyo:
1. Umthamo woMthwalo oPhuculweyo kunye nokugcinwa kweFlatness
Ubukhulu bubalulekile ekumelaneni nomzuzu wokugoba obangelwa zizinto ezinzima, ezifana noomatshini abakhulu bokulinganisa (ii-CMM) okanye izinto ezinzima. Ukukhetha ubukhulu obudlula imfuneko encinci kubonelela ngomda wokhuseleko oxabisekileyo. Ezi zinto zongezelelweyo zinika iqonga ubunzima obufunekayo kunye nesakhiwo sangaphakathi sokusasaza umthwalo ngokufanelekileyo, ngaloo ndlela kunciphisa kakhulu ukuphambuka kweplate kwaye kuqinisekiswe ukuba umphezulu ofunekayo ugcinwa ubomi bonke beqonga.
2. Uzinzo oluKhulu kunye nokuDambisa ukungcangcazela
I-granite slab etyebileyo nenzima ngokwendalo inobunzima obukhulu, nto leyo ebaluleke kakhulu ekuthomalaliseni ingxolo yoomatshini neye-acoustic. Iqonga elikhulu line-frequency ephantsi yendalo, nto leyo eyenza ukuba lingachaphazeleki kakhulu kukungcangcazela kwangaphandle kunye nomsebenzi wokunyikima oqhelekileyo kwiindawo zoshishino. Olu damping olungasebenziyo lubalulekile ekuhlolweni kwe-optical okuphezulu kunye neenkqubo zokulungelelanisa i-laser apho nentshukumo encinci inokonakalisa inkqubo.
3. Ukuphucula i-Thermal Inertia
Ukwanda komthamo wezinto ezisetyenzisiweyo kucothisa ukuguquguquka kobushushu. Nangona igranite esemgangathweni ophezulu sele ine-coefficient ephantsi kakhulu yokwandiswa kobushushu, ubukhulu obukhulu bubonelela nge-inertia ephezulu yobushushu. Oku kuthintela ukuguquguquka kobushushu okukhawulezayo, okungafaniyo nokunokwenzeka xa oomatshini befudumeza okanye imijikelo yomoya, kuqinisekisa ukuba i-geometry yereferensi yeqonga ihlala ihambelana kwaye izinzile ixesha elide lokusebenza.
Kwihlabathi lobunjineli obuchanekileyo, ubukhulu beqonga legranite abuyonto ifunekayo ukuze kongiwe iindleko, kodwa yinto esisiseko yokwakha, ukuqinisekisa ukuba ukuseta kwakho kubonelela ngeziphumo eziphindaphindwayo nezilandelekayo ezifunekayo kwimveliso yanamhlanje.
