Ingabe Ithebula Lakho Lokulinganisa I-Granite Eline-Stand Lilungiselelwe Ukunemba Okuncane Kwe-Micron Nokuzinza Kwesikhathi Eside?

Ezweni elicophelelayo le-metrology enobukhulu, indawo yokubhekisela iyindawo yokuqala yokuhlola ikhwalithi ngayinye. Eziningi izinhlelo zokusebenza, lesi sisekelo esibalulekile sinikezwa itafula lokulinganisa le-granite elinesitendi. Kunokuba yifenisha nje, lolu hlelo oluhlanganisiwe kumele lusebenze njengeyunithi eyodwa, ehlelekile ngokwesakhiwo, luqinisekisa indawo ezinzile nenezinga lokudlidliza edingekayo ukuqinisekisa ukubekezelelana kuze kufike emazingeni e-sub-micron kanye ne-nanometer.

Ukusebenza kwe-itafula lokulinganisa le-granitengezihinji zokuma hhayi nje kuphela kwikhwalithi ye-granite uqobo kodwa futhi nasekuqineni kobunjiniyela besakhiwo esisekelayo kanye nokuhlukaniswa kwayo nendawo ephansi yesitolo. I-stand ebuthakathaka ingalimaza i-granite plate engcono kakhulu, kanti i-granite plate engazinzile ingenza noma yikuphi ukulinganisa kungabi namsebenzi.

Inzuzo Yobunjiniyela: Ngale Kwepuleti Lomphezulu

Ngenkathi i-granite emnyama enokunemba okuphezulu—njengezinto eziqondene ne-ZHHIMG® ezinobukhulu obungaba ngu-3100 kg/m³—ihlinzeka ngokwandiswa okubalulekile kokushisa okuphansi kanye nokuqina okuphezulu, ukusebenza kahle kwe-itafula lokulinganisa le-granitenge-stand kuncike kakhulu ekwakhiweni kohlelo lokusekela:

• Ukuhlukaniswa Kwesakhiwo: Inhloso yesitendi ikabili: ukusekela isisindo esikhulu sepuleti le-granite ngaphandle kokuphambuka, kanye nokulihlukanisa nokudlidliza kwangaphandle. Izitendi zekhwalithi ephezulu zivame ukwakhiwa ngensimbi esindayo, ngokuvamile ngemiklamo ye-welded, yesigaba sebhokisi ukuze kwandiswe ukuqina.

• Uhlelo Lokusekela Olunamaphuzu Amathathu: Izitendi zochwepheshe zokumeta zivame ukusebenzisa uhlelo lokusekela olunamaphuzu amathathu ngaphansi kwepuleti le-granite. Lokhu kuphakeme ngokwejiyometri kunamaphuzu amane ngoba amaphuzu amathathu achaza indiza kahle, okuqinisekisa ukuthi umthwalo usatshalaliswa ngendlela ebikezelwayo futhi kususa ingozi yokugoba ipuleti ngenxa yokungalingani kobuso bephansi noma ukucindezeleka esitendini ngokwaso.

• Ukulevelisha Nokubambelela: Isiteji kumele sibe nezinyawo zokulevelisha ngokunemba, okuvumela ochwepheshe ukuthi balinganise ubuso begranite ngokushesha nangokunembile besebenzisa amazinga kagesi. Ngezinhlelo zokusebenza ezisindayo, isiteji singase sibe nezindawo zokubambelela ukuze siqine phansi, okuthuthukisa ukuzinza ngokumelene nezingxenye ezinkulu zomshini noma ama-gantries e-CMM.

Ikhwalithi yeGranite: Umongo Wokulinganisa

Ipuleti legranite ngokwalo kumele linamathele ezindinganisweni zomhlaba wonke eziqinile kakhulu, njenge-DIN 876 noma i-ASME B89.3.7, lifinyelele amamaki aphezulu njengo-0 noma u-00. Ubuningi begranite emnyama yekhwalithi ephezulu buqinisekisa ukudambisa okukhulu kokudlidliza kanye nokuqina kobukhulu, okuyizinto ezibalulekile ekulinganisweni okunembile.

Inqubo yokukhiqiza ihilela ukugaya okungaqinile, ukuqeda ukucindezeleka ngokucophelela, kanye nokugoqa okokugcina okwenziwa ochwepheshe ezindaweni ezilawulwa yisimo sezulu. Ochwepheshe bethu, abaziwa ngekhono labo lokufinyelela ukuthamba kwezinga le-nanometer, basebenzisa imishini ye-metrology ethuthukisiwe, kufaka phakathi ama-interferometer e-laser, ukuqinisekisa ukuthi ukubekezelela ukuthamba kwetafula lokulinganisa i-granite kunembile ngokuqinisekiswa futhi kuyalandeleka ngokwezindinganiso zikazwelonke.

Ukuxhumana: I-Granite kanye ne-Stand njengeSistimu

Empeleni, i-granite kanye ne-stand kumele kuphathwe njengohlelo olulodwa olubalulekile lokukala. Isibonelo, lapho itafula le-granite lisetshenziselwa ukuhlolwa kwesilinganiso sokuphakama, ukudlidliza okuncane okudluliswa phansi noma ukwanda kokushisa okuncane kwe-stand yensimbi ephansi kungaletha iphutha lokulinganisa ngokushesha.

Ngokuhlanganisa i-granite kanye ne-stand ibe yiyunithi ehlangene, evidlizayo, uhlelo luqinisekisa ukuthi:

1. Ukuphindaphinda kwenziwa kakhulu, okusho ukuthi ukulinganisa okufanayo okuthathwe ngemizuzu ehlukene kuzoletha umphumela ofanayo.

2. Ukunemba Okuphelele kuyagcinwa, njengoba ukuba yisicaba kwepuleti le-granite kuvikelwe emandleni angaphandle.

Lokhu kubaluleke kakhulu uma itafula lokulinganisa le-granite elinesitendi lisetshenziswa ukuhlola ukuhambisana kwezigaba eziqondile, ukuqinisekisa ubungako bamathuluzi omshini, noma ukusebenza njengesisekelo sohlelo lwe-CMM oluphathekayo nolunembile kakhulu.

Ukuzinikela kwikhwalithi kudlulela ekulawulweni kwemvelo kanye nezinqubo zokulinganisa ezisetshenziswa enqubweni yokukhiqiza. Izikhungo zethu, ezihlonyiswe ngezitezi ezijiyile, ezincishisiwe ngokudlidliza kanye nokulawulwa komoya okuthuthukisiwe, ziqinisekisa ukuthi ukubekezelelana okunembile kuyafezwa futhi kuqinisekiswe ngaphambi kokuba umkhiqizo usuke endaweni yethu. Ngaphezu kwalokho, uhlelo ngalunye lulethwa ngemibhalo ephelele yokulandelela, okunikeza umsebenzisi ukuqiniseka okuphelele endaweni yakhe eyisisekelo yokubhekisela.

Ukukhetha itafula lokulinganisa le-granite eliqinisekisiwe elinesitendi kuwukutshalwa kwezimali okuqondisa ikhwalithi yomkhiqizo ngamunye odlula emnyangweni wakho wokuhlola. Ukuyekethisa ekuzinzeni nasekunembile kwale nkundla ebalulekile yokubhekisela akuyona nje inketho esimweni sokukhiqiza esinzima sanamuhla.
