Iipleyiti zeGranite vs. Cast Iron Surface: Yeyiphi eyona ifanelekileyo kwiMetrology Lab yakho?

Zombini ezi zinto zisebenzele ishishini lokuvelisa kangangeminyaka engaphezu kwekhulu, kwaye zombini zinezibonelelo ezahlukeneyo ezenza zibe ngcono kwizicelo ezithile. Nangona i-granite idla ngokubizwa ngokuba yinkosi yozinzo kunye nokuchaneka, i-cast iron isasebenza kakhulu kumgangatho wemizi-mveliso. Ukuqonda iingcaciso ze-"Granite vs. Cast Iron" kubalulekile ukuqinisekisa ukuba ilabhoratri yakho ixhotyiswe ngesixhobo esifanelekileyo somsebenzi, ilinganise imfuneko yokuchaneka kwinqanaba le-nanometer ngokuchasene nobunzima bokuhlolwa okunzima.

Iipleyiti zomphezulu wegranite, ezidla ngokwenziwa ngegranite emnyama okanye i-diabase ekumgangatho ophezulu, ziye zaba ngumgangatho wegolide kwiilebhu zanamhlanje zemetrology. Ubuhle obuphambili begranite bukwimbali yayo yejoloji. La matye enziwa kwiminyaka yezigidi, edlula ekwaluphaleni kwendalo okuphelisa ngempumelelo uxinzelelo lwangaphakathi. Xa umenzi esika aze apolishe ibhloko yegranite, usebenza ngezinto esele zifikelele kwimeko yokulingana okulinganayo. Olu zinzo lwendalo luthetha ukuba ipleyiti yegranite iyakwazi ukumelana nokugoba okanye ukujika ngokuhamba kwexesha, ukuba nje ixhaswa ngokuchanekileyo.

Enye yezona nzuzo zibalulekileyo zegranite kwindawo yelebhu kukuzinza kwayo kubushushu. Kwindawo yokulinganisa ngokuchanekileyo, ubushushu butshaba. Iintsimbi ziyanda kwaye zinciphe ngobushushu, kwaye nokutshintshatshintsha okuncinci kubushushu obuphakathi kwelebhu kunokubangela ukuba ipleyiti yesinyithi yande ngokwaneleyo ukuze ikhuphe imilinganiselo ebuthathaka. Igranite ine-coefficient ephantsi kakhulu yokwanda kobushushu—iphantsi kakhulu kuneyesinyithi esityhidiweyo. Oku kuthetha ukuba ukuba ubushushu kwindawo yakho butshintsha ngamadigri ambalwa, ipleyiti yegranite iya kuhlala ingatshintshanga, igcina ukuchaneka kokufundwa kwakho. Le propati yenza igranite ibe lukhetho olufanelekileyo kwiindawo apho ukugcina ubushushu obuhlala buhleli (ubushushu obuhlala buhleli) obugqibeleleyo kunzima okanye kubiza kakhulu.

Ngaphezu koko, igranite yinto engeyoyesinyithi, enika iingenelo ezimbini ezahlukeneyo: ayinamagnethi kwaye ayichaphazeleki ngumhlwa. Kwindawo yelabhoratri apho kusetyenziswa khona izinto ze-elektroniki ezibuthathaka okanye iigeyiji zemagnethi, ipleyiti yesinyithi esityhidiweyo inokungenisa ukuphazamiseka. Igranite, ekubeni ingasebenzi kakuhle ngokweekhemikhali, ayisoze igqwale. Oku kuphelisa isidingo sokusetyenziswa rhoqo kweeoyile zokukhusela ezifunekayo kwiipleyiti zesinyithi. Ipleyiti yegranite ingagcinwa icocekile kwaye yomile, kunciphisa umngcipheko wokungcolisa iindawo ezilinganiswayo. Ukuba ulwelo luchithekile kwipleyiti yegranite, lunokusulwa ngaphandle koloyiko lokugqwala, ngelixa ukuchitheka okufanayo kwipleyiti yesinyithi esityhidiweyo kunokukhokelela ekuqhekekeni kunye nomonakalo ongunaphakade ukuba ayilungiswanga ngokukhawuleza.

Ukugqitywa komphezulu wepleyiti yegranite yenye indawo apho igqwesa khona. Ngeenkqubo eziphambili zokuleqa nokupolisha, igranite inokufikelela ekugqityweni okufana nesipili okugudileyo kakhulu. Oku kuthamba kunciphisa ukungqubana kwezixhobo zokulinganisa ezityibilikayo kwaye kuqinisekisa ukuba akukho zincopho ezincinci kunye neentlambo zokubamba ukungcola okanye inkunkuma. Xa umphezulu wegranite utshaywe okanye wonakele—umzekelo, ukuba inxalenye enzima iwele kuwo ngengozi—izinto ezisetyenziswayo zidla ngokuqhekeka okanye zenze ukuxinana. Okubalulekileyo kukuba, ayenzi “i-burr” okanye umphetho ophakanyisiweyo ojikeleze indawo echaphazelekileyo. Kwi-metrology, i-burr ephakanyisiweyo imbi kakhulu kuba iphakamisa isixhobo sokulinganisa, ibangela ukufundwa okungachanekanga kumphezulu wonke. Ukuxinana kwigranite kulula ukukwahlula kwaye kudla ngokuba nefuthe elincinci kubuthe tyaba bendawo ejikelezileyo.

Nangona i-granite ilawula ilabhoratri echanekileyo, iipleyiti zomphezulu wesinyithi esityhidiweyo zibambelela ngokuqinileyo kwiindawo zokuhlola zoshishino, amagumbi ezixhobo, nakwiindawo zokuvelisa izinto ezinzima. Ingxoxo ephambili yesinyithi esityhidiweyo bukuqina kwayo. Isinyithi esityhidiweyo sisixhobo esithambileyo xa sithelekiswa nendalo yelitye ebuthathaka. Ingamelana nomothuko omkhulu kunye nefuthe ngaphandle kokuqhekeka. Kwiworkshop exakekileyo apho izinto ezinzima ezityhidiweyo, ii-weldments, okanye iindawo zentsimbi zihlala zibekwa etafileni yokuhlolwa, ipleyiti ye-granite inokuqhekeka phantsi koxinzelelo. Nangona kunjalo, ipleyiti yesinyithi esityhidiweyo iya kuyifunxa loo mothuko.

Ukugcinwa kwesinyithi esityhidiweyo kudla ngokungaqondwa kakuhle. Nangona kuyinyani ukuba isinyithi sifuna ukukhuselwa kumhlwa, isitya sesinyithi esityhidiweyo esigcinwe kakuhle sinokuhlala amashumi eminyaka. Indlela yendabuko yokugcina ezi plate ibandakanya ukugcina ifilimu encinci yeoyile phezu komphezulu. Le oyile ayithinteli nje kuphela umhlwa kodwa isebenza njenge-lubricant kwiindawo ezityibilikayo. Ukongeza, umphezulu wesitya sesinyithi esityhidiweyo udla "ngokukrwelwa" ngesandla. Le nkqubo yesandla idala ipateni yeepokotho ezincinci phezu komphezulu. Ezi pokotho azinaziphene; ziyasebenza. Zisebenza njengeendawo zokugcina ukuthambisa kwaye zibamba naluphi na uthuli okanye i-swarf encinci enokubakho, ithintela ukuba ingaphazamisi umlinganiselo. Esi senzo "sokusonta" sivumela uhlobo oluthile lwempendulo echukumisekayo ekhethwa ngabachwephesha abaninzi abanamava kunye nabahloli.

Enye inzuzo ecacileyo yentsimbi ephosiweyo kukulungiswa kwayo. Ukuba ipleyiti yentsimbi ephosiweyo igugile okanye yonakele, ingakhuhlwa kwakhona okanye igutyungelwe kwakhona ukuze kubuyiselwe ukuchaneka kwayo kwasekuqaleni. Olu lurhwebo olunobuchule, kodwa luvumela ipleyiti eyonakeleyo ukuba ibuyiselwe ebomini, ngokuyintloko ibuyisele ubomi bayo benkonzo. Ngokwahlukileyo koko, nangona igranite inokuphinda ibekwe, inkqubo yahlukile kwaye idla ngokufuna izixhobo ezikhethekileyo ukuze ibuyisele ilitye. Kubasebenzisi abaninzi bemizi-mveliso, ukukwazi ukukhuhla nje ipleyiti ukuze ibuyele kwindawo ethe tyaba endlwini okanye kwindawo ethile yinzuzo enkulu yolungiselelo.

Ixabiso nalo liyinto ebalulekileyo. Ngokubanzi, iipleyiti zesinyithi ezixonxiweyo azibizi kakhulu ukwenziwa kunee-granite, ingakumbi ngobukhulu obukhulu. Nangona iibhloko zegranite ezinkulu zifumaneka, iindleko zokufumana nokulungisa amatye amakhulu, angenaziphene zinokuba nzima kakhulu. Isinyithi esixonxiweyo sinokuphoswa kwiimo ezinkulu nezintsonkothileyo, kuquka nezo zine-T-slots, ezibalulekileyo ekubambeni izinto ezinkulu zokusebenza. Oku kuguquguquka kwenza isinyithi esixonxiweyo sibe lukhetho olukhethwayo lokuhlanganisa kunye nokudibanisa izixhobo, apho ipleyiti isebenza njengebhentshi yokusebenzela kunye nesixhobo sokulinganisa.

Xa ukhetha phakathi kwegranite kunye nesinyithi esityhidiweyo kwilebhu yakho ye-metrology, kufuneka ujonge ngaphaya kwezinto ngokwazo kwaye ucinge ngokusetyenziswa kwazo. Ukuba inkxalabo yakho ephambili kukuchaneka okuphezulu kakhulu—njengakwilebhu yokulinganisa, igumbi le-CMM, okanye iziko lokuhlola i-optical—igranite phantse yeyona ndlela ibalaseleyo. Ukuchasana kwayo notshintsho lobushushu, ukungabikho kokuphazamiseka kwemagnethi, kunye neemfuno eziphantsi zokugcinwa kudala imeko-bume ezinzileyo yezixhobo ezinobuthathaka. Inyani yokuba ayinamhlwa ithetha ukuba ungasebenza kwindawo ecocekileyo yegumbi ngaphandle kokukhathazeka ngenkukuma yeoyile okanye amasuntswana okugqwala angcolisa iimveliso zakho.

Nangona kunjalo, ukuba "ilebhu" yakho yindawo yokuhlolwa ekumgangatho ophezulu ngaphakathi kwivenkile yoomatshini, okanye ukuba uhlola izinto ezirhabaxa nezinzima, isinyithi esityhidiweyo sinokuba sisisombululo esisebenzayo. Umngcipheko wokuwisa inxalenye yentsimbi enzima kwipleyiti yegranite luxanduva abaphathi beevenkile abaninzi abakhetha ukuluphepha. Ukuqina kwesinyithi, kunye nexabiso layo eliphantsi lokuqala kunye nokukwazi ukuyilungisa ngokuyikrwela, kuyenza ibe yinto eqinileyo kwindawo enzima. Ngaphezu koko, ukuba inkqubo yakho yokuhlola ibandakanya iindawo ezininzi ezinzima ezityibilikayo okanye ifuna ukusetyenziswa kwee-clamps kunye nezixhobo, indlela yokuzithambisa ngokwayo yomphezulu wesinyithi okrweliweyo kunye nokufumaneka kwe-T-slots kubonelela ngeenzuzo ezisebenzayo ezingenakulinganiswa nelitye.

Kwakhona kubalulekile ukuphawula indlela "yokudibanisa". Izakhiwo ezininzi eziphambili zisebenzisa zombini. Zingasebenzisa itafile enkulu yesinyithi esityhidiweyo ukuseta kokuqala kunye nokulungelelanisa iindawo ezinzima, emva koko zithuthele inxalenye kwipleyiti yegranite ekhethekileyo ukuze zilinganiswe ngokuchanekileyo nangokupheleleyo. Olu hambo lomsebenzi luphucula amandla azo zombini ezi zinto: ukuqina kwesinyithi kumsebenzi onzima, kunye nokuzinza kwegranite kumsebenzi omhle.

Ekugqibeleni, ingxoxo ethi “Granite vs. Cast Iron” ayingombandela wokuba zeziphi izinto ezingcono ngokwembono, kodwa kukuba zeziphi ezingconowenaI-Granite inika uzinzo oluphezulu, ukuchaneka, kunye nokulula kokugcinwa, okwenza ukuba ibe yintshatsheli engathandabuzekiyo yelebhu yanamhlanje elawulwa yimozulu. Isinyithi esityhidiweyo sibonelela ngokuqina, ukuguquguquka, kunye nokusebenza kakuhle kweendleko, siqinisekisa indawo yaso njengomqolo oqinileyo wokuhlolwa kwemizi-mveliso. Ngokuvavanya ngononophelo iimeko zakho zokusingqongileyo, uhlobo lweendawo ozihlolayo, kunye nobuchule bakho bokugcina ixesha elide, ungakhetha ipleyiti yomphezulu eya kusebenza njengesiseko esithembekileyo senkqubo yakho yokuqinisekisa umgangatho. Nokuba ukhetha uzinzo lwendalo lwelitye okanye ukuqina kwesinyithi okuqinileyo, isitshixo sisekuqondeni ifiziksi engasemva kwezinto kunye nokuhlonipha imida yazo.
