Izixhobo zokulinganisa igranite—ezifana neepleyiti zomphezulu, iipleyiti ze-engile, kunye nee-straightedges—zibalulekile ekufezekiseni imilinganiselo echanekileyo kwimizi-mveliso, i-aerospace, iimoto, kunye nobunjineli obuchanekileyo. Uzinzo lwazo olukhethekileyo, ukwanda kobushushu obuphantsi, kunye nokumelana nokuguguleka kuzenza zibe yimfuneko ekulinganiseni izixhobo, ekuhloleni izinto zokusebenza, nasekuqinisekiseni ukuchaneka kobukhulu. Nangona kunjalo, ukwandisa ubomi bazo kunye nokugcina ukuchaneka kwazo kuxhomekeke kwiindlela zokusebenza ezichanekileyo kunye nokugcinwa okucwangcisiweyo. Esi sikhokelo sichaza iiprotokholi eziqinisekisiweyo kushishino zokukhusela izixhobo zakho zegranite, ukuthintela iimpazamo ezibizayo, kunye nokuphucula ukuthembeka kokulinganisa—ulwazi olubalulekileyo kubavelisi bokulinganisa ngokuchanekileyo kunye namaqela olawulo lomgangatho.
1. Iindlela zokulinganisa ezikhuselekileyo kwiZixhobo zoMatshini
Xa ulinganisa izinto zokusebenza kumatshini osebenzayo (umz., iilathe, oomatshini bokugaya, iigrinder), linda ukuba izinto zokusebenza zime ngokupheleleyo, zizinzile ngaphambi kokuba uqale ukulinganisa. Ukulinganisa kwangethuba kubeka imingcipheko emibini ebalulekileyo:
- Ukuguguleka okukhawulezileyo kwemiphezulu yokulinganisa: Ukungqubana okuguquguqukayo phakathi kwezinto zokusebenza ezihambayo kunye nezixhobo zegranite kunokukrwela okanye konakalise umphezulu ogqityiweyo ngokuchanekileyo wesixhobo, okubeka emngciphekweni ukuchaneka kwexesha elide.
- Iingozi ezinkulu zokhuseleko: Kubasebenzi abasebenzisa ii-caliper zangaphandle okanye ii-probes ezineziseko ze-granite, izinto zokusebenza ezingazinzanga zinokubamba isixhobo. Kwizicelo zokuphosa, iindawo ezinemingxuma (umz., imingxunya yegesi, imingxunya yokuncitshiswa) zinokubamba imihlathi ye-caliper, zitsale isandla somqhubi kwiindawo ezihambayo—okubangela ukwenzakala okanye umonakalo kwizixhobo.
Ingcebiso ephambili: Kwimigca yemveliso ephezulu, dibanisa izinzwa zokumisa ezizenzekelayo ukuqinisekisa ukuba izinto zokusebenza azitshintshi ngaphambi kokulinganisa, nto leyo enciphisa iimpazamo zabantu kunye neengozi zokhuseleko.
2. Ukulungiswa komphezulu ngaphambi kokulinganisa
Izinto ezingcolisayo ezifana nezicucu zesinyithi, iintsalela ze-coolant, uthuli, okanye amasuntswana arhabaxa (umz., i-emery, isanti) ziyingozi enkulu ekuchanekeni kwesixhobo se-granite. Ngaphambi kokusetyenziswa ngakunye:
- Coca umphezulu wokulinganisa wesixhobo segranite ngendwangu ye-microfiber engenalo i-lint exutywe nesicoci esingenabungozi, esingena-pH (thintela i-solvents ezinzima ezinokutshiza i-granite).
- Sula umphezulu olinganisiweyo wesixhobo sokusebenza ukuze ususe inkunkuma—kwanamasuntswana amancinci angenza izithuba phakathi kwesixhobo sokusebenza kunye negranite, nto leyo ekhokelela ekufundweni okungachanekanga (umz., ukuphambuka okungalunganga/okungalunganga ekuhlolweni kokutyibilika).
Impazamo Ebalulekileyo Okufanele Uyiphephe: Ungaze usebenzise izixhobo zegranite ukulinganisa iindawo ezirhabaxa ezifana nee-blanks ze-forging, i-castings ezingalungiswanga, okanye iindawo ezine-abrasives ezifakwe kwi-includes (umz., izinto eziqhunyiswe ngesanti). Ezi ndawo ziya kungcolisa umphezulu wegranite ocoliweyo, zinciphise ngokungenakuphikiswa ukunyamezelana kwayo ngokuthe tye okanye ngokuthe tye ngokuhamba kwexesha.
3. Ukugcinwa Nokuphathwa Okufanelekileyo Ukuthintela Umonakalo
Izixhobo zegranite zihlala ixesha elide kodwa zinokwaphuka okanye ziqhekeke ukuba aziphathwanga kakuhle okanye zigcinwe ngendlela engafanelekanga. Landela le miyalelo yokugcina:
- Yahlukile kwizixhobo zokusika nezixhobo ezinzima: Ungaze ubeke izixhobo zegranite ngeefayile, iihammer, izixhobo zokujika, iidrill, okanye ezinye izixhobo. Impembelelo yezixhobo ezinzima inokubangela uxinzelelo lwangaphakathi okanye umonakalo womphezulu kwigranite.
- Kuphephe ukubeka kwiindawo ezingcangcazelayo: Musa ukushiya izixhobo zegranite ngqo kwiitafile zezixhobo zomatshini okanye kwiibhentshi zokusebenzela ngexesha lokusebenza. Ukungcangcazela komatshini kunokubangela ukuba isixhobo sitshintshe okanye siwe, nto leyo ekhokelela kwiitships okanye kumonakalo wesakhiwo.
- Sebenzisa izisombululo zokugcina ezilungiselelweyo: Kwizixhobo zegranite eziphathekayo (umz., iipleyiti ezincinci zomphezulu, imiphetho ethe tye), zigcine kwiindawo ezixineneyo neziqinileyo ezinee-foam inserts ukuthintela intshukumo kunye nokufunxa ukutshatyalaliswa. Izixhobo ezizinzileyo (umz., iipleyiti ezinkulu zomphezulu) kufuneka zifakelwe kwiziseko ezithintela ukungcangcazela ukuze zahlulwe kwiingcangcazela zomphezulu.
Umzekelo: Ii-calipers zeVernier ezisetyenziswa kwiipleyiti zereferensi zegranite mazigcinwe kwiindawo zazo zokuzikhusela zokuqala xa zingasetyenziswa—zingaze zishiywe zikhululekile kwiindawo zokusebenzela—ukuthintela ukugoba okanye ukungalungelelani kakuhle.
4. Kuphephe Ukusebenzisa Kakubi Izixhobo zeGranite Njengezixhobo Ezithatha Indawo
Izixhobo zokulinganisa i-granite zenzelwe ukulinganisa nokulinganisa kuphela—hayi imisebenzi yokuncedisa. Ukusetyenziswa gwenxa yeyona nto iphambili ebangela ukungasebenzi kakuhle kwezixhobo ngaphambi kwexesha:
- Musa ukusebenzisa ii-granite straightedges njengezixhobo zokubhala (zokumakisha imigca kwiindawo zokusebenza); oku kukrwela umphezulu ochanekileyo.
- Ungaze usebenzise iipleyiti ze-granite angle njenge "hammers ezincinci" zokucinezela izinto zokusebenza kwindawo yazo; impembelelo ingayiqhekeza i-granite okanye itshintshe ukunyamezela kwayo kwe-angular.
- Kuphephe ukusebenzisa iipleyiti zomphezulu wegranite ukukrazula iziqwenga zesinyithi okanye njengenkxaso yokuqinisa iibholiti—ukurhawuzelelwa kunye noxinzelelo kuya kunciphisa ukuthamba kwazo.
- Musa "ukungcangcazela" ngezixhobo (umz., iiprobe zegranite ezijikelezayo ezandleni); ukuwa ngengozi okanye ukungqubana kunokuphazamisa uzinzo lwangaphakathi.
Umgangatho weShishini: Qeqesha abaqhubi ukuba baqonde umahluko phakathi kwezixhobo zokulinganisa nezixhobo zesandla—bandakanya oku kwiikhosi zokuqalisa kunye nezokuhlaziya ukhuseleko rhoqo.
5. Ulawulo lobushushu: Nciphisa iziphumo zokwanda kobushushu
I-Granite inokwanda okuphantsi kobushushu (≈0.8×10⁻⁶/°C), kodwa ukuguquguquka okukhulu kobushushu kusenokuchaphazela ukuchaneka komlinganiselo. Landela le mithetho yolawulo lobushushu:
- Ubushushu obufanelekileyo bokulinganisa: Yenza imilinganiselo echanekileyo kwi-20°C (68°F)—umgangatho wamazwe ngamazwe we-dimensional metrology. Kwiindawo zeworkshop, qinisekisa ukuba isixhobo segranite kunye ne-workpiece zikwiqondo lobushushu elifanayo ngaphambi kokulinganisa. I-metal workpieces ezifudunyezwa ngomatshini (umz., ukusuka ekugayweni okanye ekuwelding) okanye ezipholiswe zi-coolants ziya kwanda okanye zinciphe, nto leyo ekhokelela kufundo olungeyonyani ukuba zilinganiswe ngoko nangoko.
- Ziphephe imithombo yobushushu: Ungaze ubeke izixhobo zegranite kufutshane nezixhobo ezivelisa ubushushu ezifana nezitofu zombane, ii-heat exchangers, okanye ilanga elithe ngqo. Ukuvezwa ixesha elide kumaqondo obushushu aphezulu kubangela ukuguquka kobushushu begranite, nto leyo etshintsha uzinzo lwayo (umz., i-1m granite straightedge evezwe kuma-30°C inokwanda nge-~0.008mm—eyaneleyo ukuphelisa imilinganiselo ye-micron).
- Ziqhelanise nezixhobo kwindawo engqongileyo: Xa ususa izixhobo zegranite kwindawo ebandayo uziyise kwindawo efudumeleyo yokusebenzela, vumela iiyure ezi-2-4 zokulinganisa ubushushu ngaphambi kokuba uzisebenzise.
6. Khusela kwiNgcoliseko yeMagnetic
I-granite ngokwayo ayisebenzisi magnethi, kodwa izixhobo zokusebenza ezininzi kunye nezixhobo zoomatshini (umz., ii-surface grinders ezinee-magnetic chucks, ii-magnetic conveyors) zivelisa amandla emagnethi aqinileyo. Ukuvezwa kwezi ndawo kunokwenza oku:
- Yenza iimagnethi zibe zizinto zesinyithi ezinamathele kwizixhobo zegranite (umz., ii-clamps, ii-probes), nto leyo ebangela ukuba iintsimbi ezichetyiweyo zinamathele kumphezulu wegranite.
- Phazamisa ukuchaneka kwezixhobo zokulinganisa ezisekelwe kumagnethi (umz., izalathisi zedayili yemagnethi) ezisetyenziswa kwiziseko zegranite.
Isilumkiso: Gcina izixhobo zegranite ubuncinane kwimitha e-1 ukusuka kwizixhobo zemagnethi. Ukuba kukho ungcoliseko, sebenzisa i-demagnetizer ukususa i-residual magnetism kwiindawo zesinyithi eziqhotyoshelweyo ngaphambi kokuba ucoce umphezulu wegranite.
Isiphelo
Ukusetyenziswa ngokufanelekileyo kunye nokugcinwa kwezixhobo zokulinganisa i-granite akuzona nje iindlela ezilungileyo zokusebenza—zilutyalo-mali kumgangatho wakho wokuvelisa kunye nexabiso eliphantsi. Ngokulandela ezi ndlela, abavelisi bokulinganisa ngokuchanekileyo banokwandisa ubomi bezixhobo (ngokuqhelekileyo nge-50% nangaphezulu), banciphise iindleko zokulinganisa, kwaye baqinisekise ukulinganisa okuzinzileyo nokuthembekileyo okuhlangabezana nemigangatho yoshishino (umz., ISO 8512, ASME B89).
