Kwimveliso echanekileyo, ukubamba ukuphakama, ubukhulu, ubunzulu, okanye ukulinganisa okuchanekileyo kufuna okungaphezulu nje kwesixhobo sokulinganisa esinesisombululo esiphezulu. Kwane-dial indicator okanye i-digital probe egqwesileyo ivelisa ukufundwa okungaguquguqukiyo ukuba ifakwe kwisiseko esingazinzanga, esiguquguqukayo, okanye esinobushushu.
Ngena kwisiseko se-granite dial—esidla ngokubizwa ngokuba sisihlalo sokulinganisa i-granite kwiindawo zokulawula umgangatho.
Ngokudibanisa umphezulu welitye lendalo elijikelezileyo elinomgca omncinci kunye nekholamu ethe nkqo eqinileyo kunye nengalo yesalathisi ehlengahlengiswayo, esi sixhobo sesiseko sinika indawo yesalathiso engaguqukiyo yokuqinisekisa ubungakanani be-micro-intshi kunye ne-sub-micron.
Ukuchaza isiseko seGranite Dial
Isiseko se-granite dial siquka izinto ezintathu ezibalulekileyo zesakhiwo:
-
IIsiseko seReferensi yeGranite: Ibhloko etyebileyo yomhlaba welitye lendalo oxineneyo kwaye ibekwe kwi-micro-lapped ukuya kwi-ultra-precise flatness tolerances (ngesiqhelo i-DIN 876 Grade 00 okanye Grade 0).
-
Ikholamu Yokuxhasa Eme nkqo: Intsika enzima yentsimbi okanye egqunywe nge-chrome enamathele ngokuqinileyo kwisiseko selitye ukuze imelane namandla okugoba.
-
Ingalo Yokukhwelisa Elungisekayo: Indlela yokusebenza yengalo eqine kakhulu ebamba izalathisi zedayile, iiprobe zedijithali ze-elektroniki, okanye iigeyiji ze-encoder ezithe nkqo kumphezulu wegranite.
Ngexesha lokuhlolwa, umqhubi ubeka uphawu lwe-zero kwi-gauge block stack okanye kwi-master setting ring ehleli kwi-granite plane. Inxalenye yovavanyo emva koko idlula phantsi kwendawo yokudibanisa i-probe. Nakuphi na ukuphambuka okuboniswe kwi-dial kubonisa utshintsho lokwenyani lwento—olungenazo iinguqu kwisiseko okanye kwi-post flexure.
Kutheni Ukhetha I-Granite Endaweni Yezitendi Zentsimbi Eyenziwe Ngesinyithi okanye Zentsimbi?
Izitendi ezincinci zokuthelekisa isinyithi zihlala zixhaphakile kumgangatho wevenkile ukuze kuhlolwe umatshini onzima. Nangona kunjalo, xa ukunyamezelana kuqina kwiindawo ezine-micron enye okanye ezine-micron encinci, izitendi zesinyithi zenza iimpazamo ezincinci zokulinganisa ezithintelwa yi-granite ngokwemvelo.
+- ...1. Uzinzo oluPhezulu lobushushu
Iikholamu zesinyithi kunye neziseko zisabela ngokukhawuleza kubushushu obuvela ezandleni zomqhubi okanye kubushushu begumbi obutshintshayo. I-granite emnyama enoxinano oluphezulu ine-coefficient yokwandiswa kobushushu ephantsi kakhulu (~ 5 ukuya ku-6 × 10⁻⁶/K), iqinisekisa ukuba umphezulu wereferensi ugcina ukuthembeka kwejometri kuyo yonke inguqu ende yokulinganisa.
2. IiDynamics zokuNxiba ezingenaBurr
Ukuphosa inxalenye yentsimbi eqinileyo kwisitendi sesinyithi kudala i-micro-crater ejikelezwe yi-ridge ephakanyisiweyo (i-burr). Loo ridge incinci ijika izinto zokusebenza zexesha elizayo, yonakalisa ukufundwa kokusicaba de iwiswe ngesandla. Xa i-granite ifumana impembelelo enkulu, iyaqhekeza ngaphakathi ngaphandle kokuphakamisa izinto ezikufutshane. Iindawo ezingqongileyo zigcina ukunyamezela kwazo kokuqala kokusicaba.
3. Ukudambisa ukungcangcazela kunye nendalo engeyiyo imagnethi
I-Granite ineempawu zendalo zokudambisa ngaphakathi, ifunxa ukungcangcazela okuncinci okukufutshane nendawo yokusebenzela engcono kakhulu kunee-alloys zesinyithi. Ngaphezu koko, ngenxa yokuba ilitye lendalo alinamagnethi ngokupheleleyo, lithintela uthuli lwesinyithi esincinci okanye ukuphazamiseka kwemagnethi ekuphazamiseni ii-probes ze-elektroniki ezibuthathaka.
Izicelo Eziphambili Kuzo Zonke Iimveliso Ezichanekileyo
Iziseko zegranite dial zisebenza njengemisebenzi yemihla ngemihla ebalulekileyo kumacandelo aliqela abalulekileyo kwezoshishino:
1. Iiworkshops zezixhobo ezichanekileyo kunye nezoomatshini
Abaqhubi basebenzisa izitendi zokuthelekisa ukuze bajonge ngokukhawuleza nangokuthembekileyo iindawo ezijikiweyo, iiphini zomhlaba, kunye neebhloko ezisikiweyo ngaphandle kweintanethi. Ukujonga i-part parallelism okanye ubukhulu bokuphakama obunyuliweyo ngokuchasene neebhloko ze-gauge kuthatha imizuzwana kwaye kususa ixesha lokuseta kwiimashini zokulinganisa ezilungelelanisiweyo.
2. IiLebhu zoLawulo loMgangatho kunye noLungiso
Kwiilabhoratri zokulinganisa eziqinisekisiweyo yi-ISO, iziseko zedayali zegranite zisebenza njengemigangatho yokudlulisa yesibini. Iigeyiji zedijithali ezinesisombululo esiphezulu (ezifana ne-Mahr okanye i-Mitutoyo electronic indicators ezifikelela kwi-0.1 μm) ezifakwe kwiindawo zegranite zeGrade 00 ezilinganisa iigeyiji zeplagi, iifoyile zobukhulu, kunye neeshims zokuchaneka.
3. Ukuhlolwa kweSemiconductor kunye neMicro-Electronics
Izixhobo zezixhobo ze-semiconductor zifuna ucoceko olugqithisileyo kunye nokugqibelela komphezulu. Izitendi ze-granite dial zibonelela ngesalathiso esihambelana negumbi elicocekileyo esingadingi zithambisi zokulwa nomhlwa, zithintela ungcoliseko lweekhemikhali kwi-silicon ethambileyo, i-ceramic, okanye i-glass substrates.

Ukuthembeka kwayo nayiphi na indawo yokuthelekisa kubuyela kumgangatho womzimba webhloko yelitye.
Izitendi zokuthelekisa ezingabizi kakhulu zihlala zisebenzisa ilitye elineembobo, elinoxinano oluphantsi okanye imabula ethambileyo, enokufunxa umswakama womoya kwaye igobe ngokuhamba kwexesha. I-metrology yomgangatho wezoshishino ifuna igranite emnyama yendalo enoxinano oluphezulu olumalunga ne-3100 kg/m³, enika iimbobo eziphantsi, amandla aphezulu okuxinzelela, kunye nokuqina okungaqhelekanga kwesakhiwo.
Ukufikelela kumlinganiselo wokuthamba ukuya kuthi ga kwi-single microns kufuna iinkqubo ezikhethekileyo zokulapha. Kwiziko lethu lokuvelisa laseJinan, iingcali zobugcisa zisebenzisa amashumi eminyaka yamava okulapha ngesandla ngesandla, zisebenzisa ii-optical autocollimators kunye namanqanaba e-elektroniki ahlukeneyo ukulungisa iindawo zokubhekisa. Ukusebenza ngaphakathi kwiindawo zokusebenzela ezilawulwa bubushushu ezinee-deep ground-vibration isolation kuqinisekisa ukuba isiseko ngasinye segranite sigcina i-geometry yaso elinganisiweyo ixesha elide emva kokufakwa.
Iingcebiso Zokugcina Isakhiwo Sichanekile
Ukugcina ukuchaneka kwesiseko se-granite dial:
-
Coca Imihla ngemihla: Sula umphezulu wegranite ngaphambi nasemva kokusebenzisa nge-isopropyl alcohol kunye nelaphu elingena-lint ukususa amasuntswana othuli angabonakaliyo.
-
Hlola iKholam: Jonga rhoqo ukuba iibholithi zokufaka iikholam ezithe nkqo zihlala ziqinile ngokuchanekileyo ukuthintela ukujika emva kokujika phantsi kwamandla okubamba ingalo yesalathisi.
-
Jikelezisa Iindawo Zokusetyenziswa: Kuphephe ukubeka iindawo ezincinci zovavanyo embindini wetafile rhoqo. Ukusasaza iindawo ezibekwe kuyo yonke indawo kuthintela ukuguguleka kwendawo ethile kangangeminyaka yokusetyenziswa rhoqo.
Ukukhetha i-granite dial stand eyenziwe kakuhle kuqinisekisa ukuba iqela lakho lokuhlola umgangatho lisebenza kwi-reference plane eqinileyo nethembekileyo—likhusela umgca wakho wemveliso kwiimpazamo ezibizayo.
