Kwihlabathi elinzima lobunjineli bokuchaneka, umda phakathi kwemveliso ephumelelayo kunye nokusilela okubizayo kudla ngokulinganiswa ngee-microns. Nokuba kukulungelelaniswa komatshini we-semiconductor lithography okanye ukuhlolwa kwezinto zenjini ye-aerospace, ukuthembeka komlinganiselo kuxhomekeke ngokupheleleyo kumphezulu wesalathiso osetyenzisiweyo. Le "datum" sisiseko esithuleyo salo lonke ulawulo lomgangatho, kwaye kangangamashumi eminyaka, iingcali bezixhomekeke ekuzinzeni kweepleyiti zomphezulu we-granite kunye neepleyiti zomphezulu wesinyithi esityhidiweyo ukuxhasa imigangatho yehlabathi.
Ukuguquka koMphezulu oNgqinisiweyo
Ngokwesiko, ipleyiti yomphezulu wesinyithi esityhidiweyo yayiyeyona nto iphambili kuyo yonke ivenkile yoomatshini. Imodulus yayo ephezulu yokuthamba kunye nokukwazi kwayo "ukukrwelwa ngesandla" kwenze ukuba ibe yeyona ifanelekileyo yokujonga ukulingana kweendawo zokudibana. Imiphezulu yesinyithi esityhidiweyo iqulethe amawaka eengongoma eziphakamileyo ezincinci kunye "neepokotho zeoyile" ezithintela ukutywinwa kwe-vacuum phakathi kwepleyiti kunye negeyiji, okuvumela ukuhamba okuthe tye kwezixhobo ezinzima.
Nangona kunjalo, njengoko iindawo zokuvelisa ziye zaba nobuchule ngakumbi,ipleyiti yomphezulu wegraniteiye yavela njengomgangatho wegolide wanamhlanje. Ngokungafaniyo nesinyithi, igranite ngokwemvelo ayichaphazeleki kukugqwala nokubola, kwaye i-coefficient yayo yokwandisa ubushushu iphantsi kakhulu. Oku kuthetha ukuba kwindawo apho amaqondo obushushu anokutshintshatshintsha khona, ipleyiti yegranite ihlala izinzile ngokwemilinganiselo, iqinisekisa ukuba umlinganiselo owuthathayo ngentsimbi yesi-8:00 AM uyafana nalowo uthatyathwe ngentsimbi yesi-4:00 PM.
Kutheni uLungiso lwePlate yomphezulu lungaxoxiswana
Ipleyiti yomphezulu ayisosixhobo "sokuyibeka uze uyilibale". Kwiinyanga zokusetyenziswa, ukungqubana kwezinto ezihambayo kunye nokuhla kothuli kunokubangela ukuguguleka kwendawo. Ezi "ntlambo" ezincinci zinokukhokelela kwiimpazamo zokulinganisa ezisasazeka kuyo yonke imveliso yakho.
Ukulinganiswa kwepleyiti yomphezulu yinkqubo yokumapha i-topography yomphezulu ukuqinisekisa ukuba iyahlangabezana nokunyamezelana okuthile okuthe tyaba (okufana neBanga 0 okanye iBanga 00). Besebenzisa ii-interferometers ze-laser okanye amanqanaba e-elektroniki achanekileyo, iingcali zinokubona umphezulu wepleyiti kwi-3D. Ukuba ipleyiti ayinyamezelani, kufuneka ibuyele kwimfezeko. Ukulinganiswa rhoqo akusiyo nje umsebenzi wokulungisa; yimfuneko yokuthobela i-ISO kunye nokukhusela kwiindleko ezimbi zokubuyiselwa kwemveliso.
Ukwandisa Ukuchaneka Ngezixhobo Ezikhethekileyo
Nangona ipleyiti ethe tyaba inika isiseko, ijiyometri entsonkothileyo ifuna iimilo ezikhethekileyo. Ezibini zezona zixhobo zibalulekileyo kwizixhobo ze-metrologist yi-granite straight edge kunye ne-granite angle plate.

I-Granite Straight Edge: Ezi zibalulekile ekujongeni ukuthe tye kunye nokuhambelana kweendlela zezixhobo zomatshini. Ngenxa yomlinganiselo wazo wokuqina-ubunzima, zinokuhamba imigama emide ngaphandle kokuphambuka okukhulu, nto leyo eyenza ukuba zibe yimfuneko ekufakweni nasekulinganisweni koomatshini abakhulu be-CNC.
-
Ipleyiti ye-Angle yeGranite: Xa umsebenzi kufuneka uhlolwe ngokuthe nkqo, ipleyiti ye-angle inika ireferensi echanekileyo ye-90-degree. Iipleyiti ze-angle ze-laboratory zigqitywa kwiindawo ezahlukeneyo ukuqinisekisa ukuba isikwere sigcinwa kuzo zonke ii-axes.
Ukuzibophelela kweZHHIMG kwiNgcali yezinto eziphathekayo
Umgangatho wesixhobo se-metrology uqala kwindawo yokumba. Kwi-ZHHIMG, sisebenzisa i-granite emnyama yekhwalithi ephezulu, efana neJinan Black, exabiswayo ngenxa yoxinano lwayo oluphezulu kunye nokuxinana okuphantsi. Olu khetho lwezinto ezithile luqinisekisa ukubaiipleyiti zomphezulu wegranitezibonelela ngokudambisa ukungcangcazela okuphezulu—uphawu olubalulekileyo kwiilabhoratri ezisebenzisa izinzwa ze-optical ezikhulisa kakhulu okanye iiprobe ze-elektroniki ezinobuthathaka.
Ngokudibanisa iindlela zemveli zokulepha ngesandla kunye netekhnoloji yokulinganisa yanamhlanje, sinikezela ngezixhobo ezingapheleli nje ekuhlangabezaneni nemigangatho yoshishino kodwa ezidlulayo. Siyaqonda ukuba abathengi bethu kwicandelo leemoto, ezonyango, kunye nezokhuselo bakha ikamva, kwaye ikamva lifuna isiseko esithe tyaba ngokugqibeleleyo.
Iindlela ezilungileyo zoLondolozo
Ukuqinisekisa ukuba izixhobo zakho ezichanekileyo zihlala ixesha elide, sicebisa inkqubo yokucoca engqongqo. Uthuli luyinto erhabaxa; nokuba zimbalwa iinxalenye ezinokusebenza njengephepha lesanti phantsi kwegeyiji enzima. Ukusebenzisa izicoci ezikhethekileyo, ezingezizo iintsalela kunye nokugcina iipleyiti zigqunyiwe xa zingasetyenziswa kunokwandisa ixesha phakathi kweeseshoni zokulinganisa iipleyiti zomphezulu. Ngaphezu koko, ukusasaza umsebenzi kuwo wonke umphezulu wepleyiti—kunokuba ibe sembindini nje—kuya kunceda ukuqinisekisa ukuba ziyaguga kangangeminyaka emininzi.
Ukuqukumbela, njengoko ukunyamezelana kwemveliso kuqhubeka nokuqina, imfuno yezixhobo zokulinganisa ezizinzileyo nezichanekileyo iya kukhula kuphela. Nokuba ukhetha ubuchule obuqinileyo be-ipleyiti yomphezulu wesinyithi esenziwe ngentsimbiokanye ukuzinza okukhulu kwenkqubo yegranite, isitshixo sempumelelo sisekuqondeni izixhobo, ijiyometri, kunye nemfuneko yokulinganisa rhoqo.
