Ngaba ufuna ukuchaneka kweNanometer? Kutheni iibhloko zeGauge ziyiKumkani yeMetrology

Kwindawo apho ubude bulinganiswa ngezigidi zee-intshi kunye nokuchaneka kuphela komgangatho-imeko efanayo efunwayo eqhuba ukuveliswa kwe-ZHHIMG® kukho isixhobo esinye esilawulayo: i-Gauge Block. Zaziwa jikelele njengee-Jo Blocks (emva komqambi wazo), iigeyiji zokutyibilika, okanye iibhloko zeHoke, ezi ntsimbi zicolekileyo nezicolisiweyo okanye iziqwenga zeceramic zisisiseko sayo yonke i-dimensional metrology. Ayizozixhobo nje; basisimbonakaliso esibonakalayo sobude obuthile, sisebenza njengeyona ndawo yesalathiso yokugqibela yokulinganisa yonke into ukusuka kwiimicrometers kunye neecaliper ukuya kwii-sine bar kunye nezalathi zokucofa kuwo wonke umzi-mveliso omkhulu.

Utshintsho kuMlinganiso: Imbali yeJo block

Ngaphambi kwe-1896, ii-workshops zoomatshini zazixhomekeke kwi-bespoke, izixhobo zokulinganisa ivenkile-i-custom-filed gauges kunye ne-specialized "Go/No-Go". Ngelixa yayisebenza, le nkqubo yayiswele eyona nto ibalulekileyo yokumiselwa komgangatho wehlabathi.

Ingqikelelo yokutshintsha umdlalo yaziswa ngumashini waseSweden okrelekrele uCarl Edvard Johansson ngo-1896. Ingcamango yenguqu epheleleyo kaJohansson yayikukudala imigangatho yobude obubodwa, obuchaneke kakhulu obunokubekwa kunye ngaphandle komthungo. Olu lutsha luthetha ukuba iibhloko ezincinci ezenziwe ngokucokisekileyo zinokudityaniswa ukuze zifezekise amawaka obude obahlukeneyo, obuchaneke kakhulu-ukuguquguquka okungazange kuviwe ngaphambili. Iibhloko zegeyiji zikaJohansson zalinganisa ngokufanelekileyo ireferensi yobude belizwe lezoshishino.

Umlingo wokuncamathela: Ukuqonda "Ukubetha"

Olona phawu lumangalisayo lwebhloko yegeyiji kukukwazi ukubambelela ngokuqinileyo kwenye ibhloko enempazamo encinci. Lo mcimbi ubizwa ngokuba yi-wringing. Iphunyezwa ngokutyibilika iibhloko ezimbini kunye, ezibangela ukuba umphezulu wazo osicaba owenziwe ngemakroskopu ukuba udibane ngokukhuselekileyo, ususa nasiphi na isikhewu somoya kunye nokunciphisa igalelo lendibaniselwano kwimpazamo iyonke.

Le propati yahlukileyo yinto enika iibhloko zegeyiji ukuba zisebenziseke ngendlela engakholelekiyo. Ngokomzekelo, ngokusebenzisa iibhloko ezintathu kuphela ukusuka kwisethi eqhelekileyo, umntu unokufikelela kwiwaka elihlukeneyo ubude-uthi, ukusuka kwi-3.000 mm ukuya kwi-3.999 mm kwi-0.001 mm increments. Liqhinga lobunjineli elinzulu elenza ukuba babaluleke kakhulu.

Amanyathelo amane okuQhuba ngokugqibeleleyo

Ukuphumeza olu nxibelelwano luchanekileyo bubuchule, ubuchule obunamanyathelo amane:

1. Ukucoca kokuqala: Qala ngokusula ngobunono iibhloko zegeyiji kwiphedi yokulungisa i-oyile.
2. Ukususwa kwe-oyile: Emva koko, sula iibhloko kwiphedi eyomileyo ukuze ususe nayiphi na ioli engaphezulu, ushiye kuphela ifilimu encinci.
3. Ukwakheka komnqamlezo: Beka ibhloko enye ngokunqamlezileyo kwelinye kwaye usebenzise uxinzelelo oluphakathi ngelixa uzityibilikisa kunye de zenze umnqamlezo.
4. Ulungelelwaniso: Okokugqibela, jikelisa iibhloko de zilungelelaniswe ngokugqibeleleyo, uzitshixe zibe sisitaki esiqinileyo, esichanekileyo.

Obu buchule bucokisekileyo bugxininisa imfuneko yokucoceka, uxinzelelo olulawulwayo, kunye nokulungelelaniswa okuchanekileyo ukufezekisa uqhagamshelwano olukhuselekileyo noluchanekileyo olufunekayo kumsebenzi we-metrological. Impumelelo yale adhesion ichazwa ngokusemthethweni ngokuthi "wringability," efuna ukugqitywa komphezulu we-1 microinch 0.025 μm m) AA okanye ngcono, kunye ne-flatness ubuncinane ye-5 μin (0.13 μm).

Ezona zenzo zilungileyo: Ukukhusela iMigangatho yakho yoBude

Ngenxa yokuchaneka kwabo ngokugqithiseleyo, iibhloko zegeyiji zifuna ukuqaphela ekuphatheni nasekugcinweni. Iingcali ziyaqonda ukuba ubomi obude kunye nokuchaneka kweseti kuxhomekeke ngokupheleleyo ekubambeleleni kwezona ndlela zilungileyo:

• UThintelo lokuTyakala: Kwakamsinyane nje emva kokusetyenziswa, iibhloko kufuneka ziphinde zifakwe ioyile okanye ziqatywe igrisi. I-Corrosion lolona tshaba luphambili lozinzo lwe-dimensional, kwaye ukutyeshela eli nyathelo kuya kutshabalalisa ngokukhawuleza ukuchaneka komphezulu.
• Ukuphatha: Hlala uphatha iibhloko emacaleni azo, ungaze uchukumise imilinganiselo ebalulekileyo. Ubushushu bomzimba kunye neoyile yolusu idluliselwa kwibhloko, ibangela ukwanda okwethutyana kunye nokugqwala okusisigxina ngokuhamba kwexesha.
• Ulawulo lobushushu: Iibhloko zegeyiji zichaneke kakhulu xa zithelekiswa nobushushu obuchazwe kumazwe ngamazwe obuyi-20℃ (68°F). Nawuphi na umlinganiselo owenziwe ngaphandle kwale meko ilawulwayo ufuna imbuyekezo yobushushu.

Isiphelo: I-Precision ZHHIMG® yakha phezu

Iibhloko zegeyiji ngamagorha angavunywanga aqinisekisa umhlaba wokwenziwa ngokuchanekileyo. Ziyindawo yesalathiso engaguqukiyo apho i-ZHHIMG® ilinganisa izixhobo zayo zokulinganisa eziphambili, iqinisekisa ukuba igranite yethu, i-ceramic, kunye nezixhobo zentsimbi zifezekisa ukunyamezela i-micrometer kunye ne-nanometer efunekayo koomatshini abaphambili behlabathi. Ngokuhlonipha imbali kunye nokubambelela kwezona zenzo zibalaseleyo zezi zixhobo ziyimfuneko, ngokudibeneyo sixhasa umgangatho wokuchaneka oqhuba inkqubela phambili yobuchwepheshe.
