Kwicandelo lokuvelisa ngokuchanekileyo, ukuthembeka nokuchaneka kwezixhobo zokulinganisa kubalulekile ukuqinisekisa umgangatho wemveliso yokugqibela. Amaqonga egranite, adla ngokusetyenziswa njengesiseko soomatshini bokulinganisa abalungelelanisiweyo (ii-CMM), izixhobo zokuhlola, kunye neendlela ezahlukeneyo zokuseta, kufuneka agcine ukuchaneka kwawo phantsi kweemeko ezahlukeneyo zomthwalo. Umthamo wokuthwala umthwalo wala maqonga awungomlinganiselo omnye ofanelekileyo, njengoko amaqonga enzelwe ukuhlangabezana neemfuno ezithile ngokusekelwe kubunzima ekulindelwe ukuba abuthwale. Ukusuka kwiimodeli ezikhaphukhaphu ukuya kwizisombululo ezinzima, ukuqonda umahluko woyilo kumaqonga egranite kubalulekile ukuqinisekisa ukuba asebenza kakuhle kwizicelo ezahlukeneyo zoshishino.
Amaqonga egranite abalulekile ekuboneleleni ngomphezulu ozinzileyo, kwaye amandla awo okuthwala umthwalo abalulekile ekugcineni ukuthamba kunye nokunciphisa ukuguquguquka ngexesha lokusetyenziswa. La maqonga kufuneka ayilwe kwaye akhiwe ngezinto, izakhiwo, kunye neendlela zokucubungula ezihambelana nezicelo zazo. Nokuba iqonga lixhasa izinto ezilula okanye oomatshini abanzima, kubalulekile ukukhetha uyilo olufanelekileyo ukuqinisekisa ukuchaneka kwexesha elide.
Kwiiplatifomu zegranite ezikhaphukhaphu, ngokuqhelekileyo ezo zingaphantsi kwama-500 kg, uyilo lujikeleza ulungelelwaniso lolwakhiwo oluchanekileyo nolukhaphukhaphu. La maplatifomu asetyenziswa kakhulu kwiindawo apho kufuneka ukuchaneka okuphezulu, kodwa ubunzima beplatifomu kufuneka buncitshiswe. Izinto ezifana negranite emnyama ye-mica ecolekileyo, enomxholo we-quartz we-30% nangaphezulu, zisetyenziswa rhoqo. Ezi zinto zibonelela ngoluhlu olufanelekileyo loxinano lwe-2.6–2.7g/cm², ukuqinisekisa ukuqina ngelixa kunciphisa ubunzima. Ubukhulu beplatifomu buhlala buphakathi kwama-50 nama-80 mm kwimodeli ye-1m × 1m, kwaye uyilo lubandakanya isakhiwo esineembambo ezingenanto kwicala elingaphantsi. Ngeembambo ezibekwe phakathi kwama-200–300mm kwaye zinobubanzi obuyi-30mm kunye nokuphakama kwe-40mm, olu yilo lubonelela ngolungelelwaniso olufanelekileyo phakathi kwamandla kunye nokunciphisa ubunzima, okwenza kube lula ngama-30% kunezakhiwo eziqinileyo. Ukongeza, i-frequency ye-resonance yeplatifomu ingaphezulu kwe-50Hz, enceda ukuthintela ukuphazamiseka okuvela kwiintshukumo.
Ukuchaneka koyilo lwala maqonga nako kubalulekile. Ukuthamba komphezulu osebenzayo kudla ngokulawulwa ukuya ngaphantsi kwe-0.005mm/100mm, ukuqinisekisa ukuguquguquka okuncinci nokuba kuphantsi kwemithwalo ephakathi.amaqonga egraniteZisetyenziswa rhoqo ekuhlanganiseni izixhobo ze-optical, ekulinganisweni kwezixhobo ezincinci, kunye nezicelo ezifanayo apho ukunxibelelana neqonga kubangela ngaphezulu kwe-60% yendawo iyonke yokuthwala, okuthintela uxinzelelo olugqithisileyo kwiindawo ezikufutshane.
Amaqonga aphakathi, aqala kwi-500 kg ukuya kwi-5000 kg, ayilwe ngesethi eyahlukileyo yezinto eziza kuqala. Nangona egcina umgangatho ophezulu wokuchaneka, la maqonga kufuneka athwale imithwalo emikhulu. Kula maqonga, i-granite ephakathi iyathandwa, idla ngokuba nomxholo we-feldspar we-40%–50%. Uxinano lunyuswa luye kwi-2.7–2.8g/cm³, kwaye ubukhulu beqonga buphakanyiswa ukuya kwi-100–150mm kwimodeli ye-1m × 2m. Icala elingaphantsi linesakhiwo esiqiniswe ngegridi, apho iimbambo eziphambili zibubanzi be-50mm, kwaye iimbambo ezinqamlezileyo zibubanzi be-30mm, zenza igridi ye-100×100mm. Amanqaku oxinzelelo ajikeleziswa kwiikona ukunciphisa uxinzelelo. Olu lwakhiwo lwegridi luqinisekisa ukuba iqonga ligcina amandla alo kwaye linciphisa ukugoba.
Ukuze kubekho ukuchaneka okongeziweyo, la maqonga adla ngokuba ne-T-slots (ububanzi obuyi-12–16mm) yokufakela izixhobo, kunye nesithuba sesithuba esiqala kwi-100mm ukuya kwi-150mm. Izithuba zibekwe ukuze kuthintelwe ubuthathaka bamandla eqonga, kunye nomgama omncinci we-30mm ukusuka kwicala elingaphantsi. Ngexesha lokufakwa, izixhobo ezilungisekayo zisetyenziselwa ukusasaza umthwalo ngokulinganayo, kunye neendawo ezine zokuxhasa ngemitha yesikwere, ukuqinisekisa ukuba ukuphambuka komthwalo kuhlala ngaphakathi kwe-5%. La maqonga adla ngokusetyenziswa kwiimashini zokulinganisa ezidibeneyo, ukuhlolwa kwesikhunta esiphakathi, kunye nokusetyenziswa okufanayo, apho ukuphambuka okuphezulu okuvumelekileyo yi-≤ L/10000 (L bubude beqonga).
Amaqonga anzima, enzelwe imithwalo engaphezulu kwama-5000 kg, akhiwe ukuze amelane nokuguquguquka phantsi kobunzima obukhulu. La maqonga enziwe ngegranite erhabaxa, enekristale yequartz engaphezulu kwe-2mm, kwaye anobunzima obungaphezulu kwe-2.8g/cm³. Amandla okuxinwa kwesi sixhobo adla ngokuba ngaphezulu kwe-200 MPa, kwaye ubukhulu bala maqonga buqala kwi-200 ukuya kwi-300mm kwimodeli ye-2m × 3m. Isakhiwo siqinile, sinesiseko esityebileyo (ubude be-50mm) esiqhagamshela kwiqonga eliphambili ngesiseko esimile okweqanda esine-epoxy resin bonding (enamandla okucheba ≥ 15 MPa).
Kwiiplatifomu ezinzima, ukufakelwa kufuna ukulungiswa komhlaba othile. Isiseko sekhonkrithi kufuneka sibe nobukhulu obuyi-300mm, kunye neepleyiti zentsimbi ezifakwe kwi-Q235. Phakathi kwesiseko kunye neplatifomu, kusetyenziswa umaleko werabha ye-chloroprene enobukhulu obuyi-3mm ukuqinisekisa ukusasazwa koxinzelelo olufanayo. Isiseko kufuneka sibe nomthamo wokuthwala umthwalo obuyi-0.3 MPa ubuncinane. La maplatifomu asetyenziswa kwizicelo ezinje ngokuhlolwa kwezixhobo zoomatshini ezinzima kunye noyilo olukhulu lwe-casting, apho ukuguquguquka kwexesha elide kufuneka kuhlale ngaphantsi kwe-0.002mm ngonyaka.
Imigangatho yovavanyo lweeplatifomu zegranite ezahlukeneyo ezithwala umthwalo nayo yahlukile kakhulu. Iiplatifomu ezikhaphukhaphu zivavanyelwa ukungcangcazela (10-500Hz sweep frequency, amplitude 0.1mm) ukuqinisekisa ukuba akukho resonance iyenzekayo. Iiplatifomu ezinomthwalo ophakathi zivavanyelwa umthwalo ongaguqukiyo ophindwe ka-1.2 amandla azo alinganisiweyo, kunye nokuguquguquka okungadluli kwi-0.001mm emva kweeyure ezingama-24 zokusetyenziswa kunye nokususwa komthwalo. Iiplatifomu ezinomthwalo onzima zivavanyelwa ukumelana nokudinwa, kunye nemijikelo yokukhulula umthwalo eyi-1000 kwi-80% yomthwalo wazo olinganisiweyo ukuqinisekisa ukuba akukho mifantu ibonakalayo, iqinisekiswe ngokuchongwa kweziphene ezingenayo.
Xa ukhetha iqonga legranite elifanelekileyo, kubalulekile ukufanisa uyilo neemfuno ezithile zesicelo. Kumashishini afuna ukuchaneka okuphezulu kunye nomthamo womthwalo onzima, ukukhetha uyilo lweqonga elifanelekileyo kuqinisekisa ukusebenza kunye nokuthembeka kwexesha elide. I-ZHHIMG iyaqonda ukubaluleka kwezisombululo ezenziwe ngokwezifiso ezenzelwe ukuhlangabezana neemfuno ezizodwa zomthengi ngamnye, inikezela uluhlu lweeqonga zegranite ezibonelela ngokuchaneka okuphezulu, uzinzo, kunye nokuqina phantsi kweemeko ezahlukeneyo zokulayisha.
Apha kwi-ZHHIMG, sinikezela ngoluhlu olubanzi lwamaqonga e-granite, enzelwe ukuhlangabezana neemfuno zamashishini ukusuka ekuchwethezeni ngokuchanekileyo ukuya ekuhlolweni okunzima. Amaqonga ethu ayilwe ngemigangatho ephezulu yomgangatho ukuqinisekisa ukusebenza okugqwesileyo, okubonelela ngokuchanekileyo nangokuthembekileyo, nokuba zingakanani na iimfuno zokuthwala umthwalo. Ukuzinikela kwethu ekuveliseni izinto ezintsha kunye nomgangatho kusivumela ukuba sizise izisombululo ezihlala ixesha elide, sikunike isiseko esifanelekileyo seemfuno zakho zokwenza ngokuchanekileyo.
