Nangona kunjalo, ukwandisa ubomi babo kunye nokugcina ukuchaneka kwabo kuxhomekeke kwiindlela zokusebenza ezichanekileyo kunye nokugcinwa okucwangcisiweyo. Esi sikhokelo sichaza iiprothokholi eziqinisekisiweyo kushishino ukukhusela izixhobo zakho zegranite, ukuphepha iimpazamo ezibiza kakhulu, kunye nokwandisa ukuthembeka komlinganiselo-ulwazi olubalulekileyo kubenzi bomlinganiselo ochanekileyo kunye namaqela olawulo lomgangatho.
1. IiNdlela eziKhuselekileyo zoMlinganiso kwiZixhobo zoMachining
Xa ulinganisa izixhobo zokusebenza koomatshini abasebenzayo (umzekelo, iileyile, oomatshini bokungqusha, oomatshini bokusila), hlala ulindele ukuba i-workpiece ifike ime ngokupheleleyo, izinzile phambi kokuba uqalise imilinganiselo. Umlinganiselo wangaphambi kwexesha ubeka imingcipheko emibini ebalulekileyo:
- Ukunxiba okukhawulezileyo komgangatho wokulinganisa: Ukungqubana okuguquguqukayo phakathi kwezixhobo zokusebenza ezihambayo kunye nezixhobo zegranite zinokukrwela okanye zithobe umgangatho wesixhobo ogqityiweyo ngokuchanekileyo, oko kubeke esichengeni ukuchaneka kwexesha elide.
- Iingozi ezinzima zokhuseleko: Kubasebenzisi abasebenzisa iikhalipha zangaphandle okanye iiprobe ezineziseko zegranite, izixhobo zokusebenza ezingazinzanga zinokusibamba isixhobo. Xa kugalelwa izinto, iindawo ezinemingxuma (umzekelo, imingxuma yerhasi, imingxunya eshwabeneyo) zinokubamba imihlathi yecaliper, zitsalele isandla somqhubi kwiindawo ezihambayo—okukhokelela kukwenzakala okanye ukonakala kwesixhobo.
Ingcebiso engundoqo: Kwimigca yokuvelisa umthamo ophezulu, hlanganisa i-automated stop sensors ukuqinisekisa ukuba izinto zokusebenza zimile phambi kokulinganisa, ukunciphisa iimpazamo zabantu kunye nemingcipheko yokhuseleko.
2. ULungiselelo lwangaphambi koMlinganiselo womphezulu
Izingcolisi ezifana nokuchetywa kwesinyithi, iintsalela zokupholisa, uthuli, okanye amasuntswana abrasive (umzekelo, i-emery, isanti) zizoyikiso ezinkulu zokuchaneka kwesixhobo segranite. Ngaphambi kokusetyenziswa ngakunye:
- Coca umphezulu womlinganiselo wesixhobo segranite ngelaphu le-microfiber elingena-lint elithotywe ngesicoci esingaqholiyo, i-pH-neutral (ziphephe izinyibilikisi ezirhabaxa ezinokugqabhuka igraniti).
- Sula umphezulu olinganisiweyo wesixhobo sokusebenza ukuze ususe inkunkuma—kwanamasuntswana e-microscopic anokudala izikhewu phakathi kwendawo yokusebenza negranite, ekhokelela ekufundweni okungachanekanga (umzekelo, ukutenxa okungeyonyani/negative ekuhlolweni kobutyapha).
Impazamo Ebalulekileyo YokuPhepha: Ungaze usebenzise izixhobo zegranite ukulinganisa iindawo ezirhabaxa ezifana neendawo ezingenanto zokubumba, izinto ezisantiweyo ezingalungiswanga, okanye imiphezulu eneziqhushumbisi ezishunyekelweyo (umz., amacandelo esanti). Le miphezulu iyakuwohloka umphezulu okhazimlisiweyo wegranite, icuthe ngokungenakujikwa ukuba mcaba okanye ukunyamezelana ngokuthe tye ekuhambeni kwexesha.
3. UGcino oluLungileyo kunye nokuPhathwa ukuThintela ukonakala
Izixhobo zeGranite zomelele kodwa ziyakwazi ukuqhekeka okanye ukuqhekeka ukuba aziphathwanga kakuhle okanye zigcinwe ngokuchanekileyo. Landela ezi zikhokelo zokugcina:
- Yahlukana nezixhobo zokusika kunye nezixhobo ezinzima: Ungaze uqokelele izixhobo zegranite ngeefayile, iihamile, izixhobo ezijikajikayo, iidrili, okanye ezinye iihardware. Impembelelo evela kwizixhobo ezinzima inokubangela uxinzelelo lwangaphakathi okanye umonakalo ongaphezulu kwigranite
- Kuphephe ukubekwa kwindawo engcangcazelayo: Musa ukushiya izixhobo zegranite ngokuthe ngqo kwiitafile zesixhobo somatshini okanye iibhentshi zokusebenza ngexesha lokusebenza. Ukungcangcazela komatshini kunokubangela ukuba isixhobo sitshintshe okanye siwe, nto leyo ekhokelela kwiichips okanye ukonakala kolwakhiwo
- Sebenzisa izisombululo ezizinikeleyo zokugcina: Kwizixhobo eziphathwayo zegranite (umzekelo, iipleyiti zomphezulu ezincinci, ii-straightedges), zigcine kwindawo ekhuselweyo, eqinile kunye nokufakwa kwamagwebu ukuthintela intshukumo kunye nokufunxa ukothuka. Izixhobo ezizinzileyo (umzekelo, iipleyiti zomphezulu ezinkulu) kufuneka zixhonywe kwiziseko ezingcangcazelayo ukuze zibe zodwa kungcangcazelo lomgangatho.
Umzekelo: Iicaliper ze-Vernier ezisetyenziselwa iipleyiti zereferensi yegranite kufuneka zigcinwe kwiimeko zazo zokukhusela zangaphambili xa zingasetyenziswanga-aze zishiywe zikhululekile kwiibhentshi zokusebenza-ukuphepha ukugoba okanye ukungahambi kakuhle.
4. Kuphephe ukuSebenzisa Kakubi iZixhobo zeGranite njengeSixhobo esiBambelela
Izixhobo zokulinganisa i-Granite zenzelwe ngokukodwa ukulinganisa kunye nokulinganisa-kungekhona kwimisebenzi yokuncedisa. Ukusetyenziswa kakubi ngoyena nobangela wokungaphumeleli kwesixhobo kwangaphambi kwexesha:
- Musa ukusebenzisa i-granite straightedges njengezixhobo zokubhala (ukumakisha imigca kwizinto zokusebenza); oku kukrwempa umphezulu ochanekileyo.
- Ungaze usebenzise iipleyiti ze-engile yegranite njenge “ihamile ezincinci” ukucofa izixhobo zokusebenza kwindawo; Impembelelo inokuqhekeka igranite okanye ijike ukunyamezela kwayo
- Kuphephe ukusebenzisa iipleyiti zangaphezulu zegranite ukukhuhla iitshefu zesinyithi okanye njengenkxaso yokuqinisa iibholithi—ukugqabhuka noxinzelelo kuya kuthomalalisa ukucaba kwazo.
- Kuthintele “ukugexa” ngezixhobo (umzekelo, ukusonta iiprobe zegranite ezandleni); ukuhla ngengozi okanye iimpembelelo zinokuphazamisa uzinzo lwangaphakathi
Umgangatho woShishino: Qeqesha abaqhubi ukuba bawubone umahluko phakathi kwezixhobo zokulinganisa kunye nezixhobo zesandla-kuquka oku kukhwela kunye nezifundo zokuhlaziya ukhuseleko rhoqo.
5. Ulawulo lobushushu: Nciphisa iimpembelelo zoKwandiswa kweThermal
I-Granite inokwandiswa kwe-thermal ephantsi (≈0.8×10⁻⁶/°C), kodwa ukuguquguquka okukhulu kobushushu kusenokuthi kuchaphazele ukuchaneka komlinganiselo. Landela le mithetho yolawulo lobushushu:
- Umlinganiselo ofanelekileyo wobushushu: Yenza imilinganiselo echanekileyo kwi-20°C (68°F)—umgangatho wamazwe ngamazwe we-dimensional metrology. Kwiindawo zokusebenzela, qinisekisa ukuba isixhobo segranite kunye nesixhobo sokusebenza sikwiqondo lobushushu elifanayo phambi kokulinganisa. Izinto zokusebenza zesinyithi ezifudunyezwa ngoomatshini (umzekelo, ukusuka ekusileni okanye ekutshiselweni) okanye zipholile ngezinto zokupholisa ziya kwanda okanye zinciphe, nto leyo ekhokelela ekufundweni okungeyonyani ukuba kulinganiswa ngoko nangoko.
- Baphephe imithombo yobushushu: Ungaze ubeke izixhobo zegranite kufutshane nezixhobo ezenza ubushushu ezifana neziko lombane, izitshintshi zobushushu, okanye ukukhanya kwelanga ngqo. Ukuba sesichengeni ixesha elide kumaqondo obushushu aphezulu kubangela ukuguquguquka kwe-thermal yegranite, iguqule ukuzinza kwayo komda (umzekelo, i-1m yegranite eqondileyo evezwe kuma-30°C inokwandiswa nge ~0.008mm—eyanele ukuba ingasebenzi imilinganiselo yomgangatho wemicron).
- Izixhobo ezihambelana nendalo: Xa ususa izixhobo zegranite kwindawo yokugcina ebandayo ukuya kwindawo yokusebenzela efudumeleyo, vumela iiyure ezi-2 ukuya kwezi-4 zokulinganisa ubushushu ngaphambi kokusetyenziswa.
6. Khusela ekungcolisekeni kweMagnetic
Igranite ngokwayo ayinamagnetic, kodwa izixhobo zokusebenza ezininzi kunye nezixhobo zokusebenza (umzekelo, izisidi ezingaphezulu ezinemagnethi, iimagnethi zokuhambisa) zivelisa umhlaba owomeleleyo wemagnethi. Ukuvezwa kwezi ndawo kunoku:
- Izinto zentsimbi ezidityaniswe ngemagnethi zincanyathiselwe kwizixhobo zegranite (umzekelo, iiclamps, probes), ezibangela ukuba iitsheti zentsimbi zibambelele kumphezulu wegranite.
- Ukuphazamisa ukuchaneka kwezixhobo zokulinganisa ezisekelwe kumagnethi (umzekelo, izibonisi zokudayela kumagnethi) ezisetyenziswa neziseko zegranite.
Isilumkiso: Gcina izixhobo zegranite ubuncinane ngemitha enye kude nesixhobo sombane. Ukuba ungcoliseko lukrokrelwa, sebenzisa i-demagnetizer ukususa i-magnetism eshiyekileyo kwiindawo zentsimbi ezincanyathiselweyo ngaphambi kokucoca umphezulu wegranite.
