Emkhakheni obaluleke kakhulu wokukhiqiza ngokunemba okukhulu, isidingo samathuluzi okubhekisela azinzile, athembekile, futhi anembe kakhulu asikaze sibe sikhulu kangaka. Ngenkathi izinhlelo ze-metrology zedijithali zibamba izihloko, impumelelo yokugcina yanoma yikuphi ukuhlanganiswa okunembile kakhulu—kusukela emishinini ye-semiconductor kuya emishinini ye-CNC ethuthukisiwe—isancike ekuthembekeni kwamaphuzu ayo okubhekisela ngokomzimba. Phakathi kwalokhu, irula lesikwele se-granite livelele njengethuluzi eliyisisekelo, kodwa kuphela uma lifinyelela isitifiketi esiphezulu kakhulu: i-DIN 00.
Ukufinyelela ibanga le-DIN 00 akuyona nje into ehlelekile; kusho izinga lokuphelela kwejiyometri elihumushela ngqo ekunembileni okusebenzayo, okungaqinisekiswa endaweni yokukhiqiza. Leli zinga lokunemba liyisisekelo sokuqondanisa imishini yesimanje kanye nokulawula ikhwalithi, elisebenza njenge-"master square" ebalulekile yokuqinisekisa amajiyometri omshini, ukuhlola ukujiya kwama-axis e-CMM, nokuqinisekisa ubunjalo bezinhlelo zokunyakaza eziqondile.
Ukubaluleka kwe-DIN 00: Ukuchaza Ukuphelela Kwejiyometri
Izinga le-Deutsche Industrie Norm (DIN) 875 lichaza ngokucophelela ukuphambuka okuvunyelwe kokusicaba, ukunemba, kanye nobungqingili kumathuluzi okulinganisa ngokunemba. I-DIN 00 imelela isiqongo salolu hlobo lwesigaba, "ibanga lokulinganisa," eligcinelwe izinsimbi ezisetshenziswa kuma-laboratory okulinganisa abucayi kakhulu kanye nanjengezingcweti zokuhlola ezinye izinsimbi.
Ngenani elikhuluirula yesikwele segraniteukuze ithwale uphawu lwe-DIN 00, ubuso bayo obuyinhloko kumele bubonise ukuthambekela okucishe kube okuphelele kanye nokuqondile, ngokubekezelela okuqinile kakhulu kokuphambuka kulo lonke ubude bayo. Leli zinga lokunemba libalulekile ngoba noma yiliphi iphutha le-angular ku-rula liyanda uma lisetshenziswa ukuqondisa ama-axe amakhulu omshini noma izindiza zokubhekisela. Uma i-rula ingekho isikwele ngokuphelele, ithuluzi lomshini elihambisana nalo lizothwala lelo phutha ngokwemvelo, okuholela ekungalungini kobukhulu engxenyeni yokugcina eyenziwe.
Isibopho Sezinto Ezibonakalayo: Kungani I-Granite Iphumelela Lapho Insimbi Ihluleka Khona
Ukukhetha izinto zokwakha kuyisinyathelo sokuqala esibalulekile sokufinyelela ukunemba kwe-DIN 00. Nakuba izikwele zensimbi zivame, azifanelekeli ngokuphelele indawo enamandla nenembile yokukhiqiza yesimanje ngenxa yokuthambekela kwazo ekukhuleni nasekugqwaleni kokushisa.
I-granite esezingeni eliphezulu, ikakhulukazi i-gabbro emnyama ejiyile njengezinto ze-ZHHIMG® (ubuningi ≈3100 kg/m³), inikeza izinzuzo ezintathu ezibalulekile ezenza i-granite square ruler ibe ngcono ukuze iqine:
-
Ukwanda Okuphansi Kokushisa: I-Granite ibonisa i-coefficient yokwanda kokushisa ephansi kakhulu—ephansi kakhulu kunensimbi. Endaweni elawulwa ukushisa, lokhu kuqinisekisa ukuthi i-geometry yombusi ihlala ingashintshi, igcina isitifiketi sayo se-DIN 00 ngaphandle kwengozi yephutha elibangelwa ukwanda.
-
Ukuqina Okuphezulu Nokumanzisa: I-modulus ephezulu yokunwebeka okukhona ku-granite emnyama yekhwalithi ephezulu inikeza ukuqina okungavamile. Lokhu kuqina kunciphisa ukuphambuka lapho i-rula ilawulwa noma ibekwa ngaphansi komthwalo. Ngaphezu kwalokho, isakhiwo sayo semvelo sinciphisa ngempumelelo ukudlidliza, okuyisici esibalulekile lapho i-rula isetshenziswa kanye nezinsimbi zokulinganisa ezibucayi phansi kwesitolo.
-
Ayinamagnetic futhi ayimelani nokugqwala: I-Granite ayigqwali noma ayidingi izembozo ezivikelayo, iqinisekisa ukuthi ubuso bayo obusebenzayo buhlala buhlanzekile futhi buzinzile ngokwejiyometriki eminyakeni eminingi yokusetshenziswa. Lokhu kuqeda ukungaqiniseki okubangelwa ukuphazamiseka okungenzeka kumagnetic ekuhlolweni kokuqondanisa okubandakanya izingxenye ze-electromagnetic.
Ipayipi Lobunjiniyela Obunembile: Kusukela Etsheni Kuya Ejwayelekile
Ukufinyelela ibanga le-DIN 00 ku-airula yesikwele segranitekuyinqubo yokukhiqiza eyinkimbinkimbi, enezigaba eziningi ehlanganisa ubuchwepheshe obuthuthukisiwe nekhono lobuciko elingenakuphikwa. Iqala ngokukhethwa kwamabhulokhi e-granite angaphakathi angenangcindezi futhi iqhubekela phambili ngokugaya okunzima, ukuguga kokuqeda ukucindezeleka, kanye nenqubo yokuhlanganisa izigaba eziningi.
Izigaba zokugcina nezibucayi zokulungiswa kwejiyometri zivame ukwenziwa ezindaweni zokucwaninga ezilawulwa kakhulu isimo sezulu, lapho izinga lokushisa kanye nomswakama kulawulwa ngokuqinile ukuze kuqedwe izinto eziguquguqukayo zemvelo. Lapha, ochwepheshe be-metrology abangochwepheshe basebenzisa imishini yokulinganisa eyinkimbinkimbi—kufaka phakathi ama-autocollimator, ama-laser tracker, kanye namazinga kagesi—ukuqinisekisa ukuthambekela kanye nokuqondile kobuso bombusi. Ukulungiswa kokugcina kwenziwa ngokugoqa ngesandla ngokucophelela. Laba bangcweti, ngezinye izikhathi ababizwa ngokuthi “amazinga kagesi ahambayo,” banolwazi lokuthinta ukususa izinto ezingeni le-sub-micron, okwenza umbusi ahambisane nokubekezelelana okuncane okungenamkhawulo okudingeka yi-DIN 00.
Igunya lomkhiqizo wokugcina liqinisekiswa kuphela ngokulinganisa okucophelelayo nokulandelekayo. Wonke umbusi wesikwele wegranite wezinga eliphezulu kumele aqinisekiswe kusetshenziswa izinsimbi ezilandelekayo ezibuyela ezikhungweni ze-metrology zikazwelonke. Lokhu kuqinisekisa ukuthi ithuluzi aligcini nje ngokuba linembile kodwa linembile ngokuqinisekiswa ngokwezinga lomhlaba wonke, elivunyelwene ngalo.
Ngale Kwelebhu: Ukusetshenziswa Kwesikwele Se-DIN 00 Granite
Isidingo sombusi wesikwele se-granite onesitifiketi se-DIN 00 sibonisa indima yaso ebalulekile kuzo zonke izimboni ezithintekayo:
-
Ukuqondaniswa Kwamathuluzi Omshini: Kusetshenziswa ukuqinisekisa ubungako bezinsika zamathuluzi omshini (XY, YZ, XZ) ngemva kokufakwa noma ukulungiswa, ukuqinisekisa ukuthi ukunemba kwejometri yomshini kuyagcinwa ukuze kukhiqizwe izingxenye ezibekezelela kakhulu.
-
Ukuqinisekiswa kwe-CMM: Ukusebenza njengengcweti yokubhekisela ekulinganiseni nasekuqinisekiseni uhlelo lwe-probe kanye nokunemba kokunyakaza kweMishini Yokulinganisa Ehlanganisiwe, okuyiwona ngokwawo amathuluzi okulawula ikhwalithi ayinhloko.
-
Ukuhlanganiswa Kwezigaba Zokucacisa: Kusetshenziswa ekuhlanganisweni nasekuqondisweni kwezigaba zokunyakaza eziqondile kanye nezinhlelo zokuthwala umoya ezivamile emishinini yokuphatha i-semiconductor kanye nasekukhiqizweni kokubonisa kwephaneli eyisicaba, lapho ukulingana okunembile kubaluleke kakhulu ekusebenzeni okuphumelelayo.
-
Ukuqondanisa Okubonakalayo: Ukunikeza i-reference plane eyisikwele ngempela yokuvumelanisa amabhodi okukhanyisa ayinkimbinkimbi kanye nezinhlelo ze-laser lapho ukuzinza kwe-angular kubalulekile khona ekuqineni kwendlela yemisebe.
Ukuphila isikhathi eside kanye nokuqina kwerula lesikwele segranite ene-DIN 00 kuyenza ibe yimpahla eyisisekelo, yesikhathi eside kunoma iyiphi ilabhorethri yokukhiqiza ethuthukisiwe noma ye-metrology. Imelela ukutshalwa kwezimali hhayi nje ethuluzini, kodwa esisekelweni esiqinisekisiwe nesiphelele sokunemba kobukhulu lapho zonke izilinganiso nokuqondanisa okulandelayo kuncike khona. Kubakhiqizi abalwela ukunemba kwangempela, noma yini engaphansi kwe-DIN 00 imane iletha ingozi engamukeleki.
