Ezweni lobunjiniyela bokunemba—kungakhathaliseki ukuthi wakha ama-micro-molds amadivayisi ezokwelapha, ukuhlanganisa izingxenye ze-optical, noma ukuqinisekisa ukufakwa kwezindiza okubekezelelana kakhulu—umkhawulo wephutha mncane kakhulu. Kodwa ochwepheshe abaningi bayayishaya indiva into elula ngokumangalisayo kodwa ebaluleke kakhulu engalimaza buthule ngisho nemisebenzi ethuthukisiwe kakhulu: indawo yokubhekisela abayisebenzisa nsuku zonke. Akukhona njalo ngobuchwepheshe bezinsimbi zakho; ngezinye izikhathi, kumayelana nokuzinza okungaphansi kwazo. Futhi lapho isikhala silinganiselwe noma imisebenzi ibucayi, ipuleti elincane elifanele lingenza umehluko omkhulu.
Nakuba amatafula okuhlola i-granite amakhulu ebusa amalebhu okukala, izitolo ezincane, iminyango ye-R&D, kanye namaqembu enkonzo yasensimini athembela kakhulu kumapulatifomu e-granite amancane, asezingeni eliphezulu ukuqinisekisa ukunemba lapho isikhala sebhentshi sincane khona futhi ukuthwaleka kubalulekile. Lawa akuwona amathuluzi "aphansi"—yizixazululo ezakhiwe ngenhloso ezenzelwe ukuletha ubuqotho obufanayo bezinto ezibonakalayo kanye nokusebenza okuthe tyaba njengontanga bazo abakhulu, ezilinganiselwe izinhlelo zokusebenza ezigxile. Kuhlanganiswe nokwethenjelwaamathuluzi okulinganisa i-granite—njengezilinganiso zokuphakama, izinkomba zokudayela, amabhlogo egeji, kanye nezikwele zokunemba — ipuleti elincane elingaphezulu liba yiseli le-metrology eliphathekayo, okwenza kube nokulinganisa okulandelekayo noma kuphi kusukela phansi kokukhiqiza kuya ebhentshini legumbi lokuhlanza.
Kodwa nansi inkinga: usayizi awukukhululi emthwalweni wokulinganisa. Njengezinhlelo ezinkulu, lezi zinkomba ezincane zidinga ukulinganiswa kwetafula lobuso ngezikhathi ezithile ukuze zihlale zithembekile. Ukuphambuka kwama-microns ama-5 kuphela epuletini elingu-200 x 300 mm kungase kubonakale kuncane—kuze kube yilapho ulinganisa ukubekezelelana okungu-0.01 mm ku-nozzle ye-fuel injector noma ukuvumelanisa isiphathi se-semiconductor wafer. Ngaleso silinganiso, ngisho nokugoba okuncane noma ukuguguleka kwendawo kungangena ekufundweni okungamanga, kulungiswe kabusha, noma kungabonakali ukungaguquguquki. Yingakho abakhiqizi abahamba phambili bephatha yonke inkomba ye-granite—kungakhathaliseki usayizi—njengento yobuciko elinganisiwe, hhayi nje itshe elilula.
Isayensi ngemuva kwalokhu kuthembeka itholakala ezimpahleni ze-granite emnyama yebanga le-metrology uqobo. Ngokungafani nensimbi ephonswe noma insimbi, ekhula ngokushintsha kwezinga lokushisa futhi igqwale ngokuhamba kwesikhathi, i-granite inikeza ukuzinza okumangalisayo kobukhulu. I-coefficient yayo ephansi yokwanda kokushisa (ngokuvamile i-6–8 µm/m·°C), ukuminyana okuphezulu (~2.97 g/cm³), kanye nezici zemvelo zokudlidliza kwenza kube kuhle kakhulu emsebenzini wokunemba. Uma ihlanganiswe kahle ku-Grade 0 noma ku-Grade 00 flatness ngokwezindinganiso ze-ISO 8512-2 noma ze-ASME B89.3.7, ipuleti elincane elingaphezulu linikeza iplanethi yangempela yejiyometri ehlala ifana kuzo zonke izimo ze-workshop ezijwayelekile.
Lokhu kuvumelana yikho okwenza kube nokunembaitafula le-graniteizinqubo zokulinganisa. Kungakhathaliseki ukuthi ucindezela amabhlogo e-gage ukuze usethe i-height master, uhlola ubunjalo besikwele nge-engeli enembile, noma usebenzisa isibonakaliso sokudayela sohlobo lwe-lever ukuqinisekisa ukuqedwa, lonke uchungechunge lokulinganisa luthatha ukuthi ubuso besisekelo buphelele. Uma kungenjalo, konke ukufundwa kuzuza lelo phutha—buthule futhi kungabonakali. Yingakho izinhlelo zekhwalithi ephezulu zingagcini nje ngokuba nezindawo ze-granite; zibhala umlando wazo wokulinganisa, zilawula indawo yazo, futhi ziwayeke kuphela lapho ukulinganisa kabusha kuqinisekisa ukuthi zidlule imingcele eyamukelekayo.
Kwa-ZHHIMG, sisebenze namakhasimende aqale alahla isidingo sepuleti elincane eliqinisekisiwe, uma sicabanga ukuthi ibhentshi labo labasebenza ngomshini noma ucezu lwe-granite elahliwe kwanele. Omunye umenzi wezinto zikagesi eJalimane wathola ukuthi ukulinganiswa kwe-probe tip okungaguquki kwalandelwa emuva esisekelweni se-aluminium esigobile ababesisebenzise iminyaka eminingi. Ngemva kokushintshela epuletini elincane elingaphansi le-300 x 450 mm le-Grade 0 elinesitifiketi sokulinganisa esigcwele, ukuphindaphinda kwawo kwathuthuka ngaphezu kuka-60%. Amathuluzi abo ayengashintshile—kodwa isisekelo sabo sasishintshile.
Okubaluleke ngokufanayo ukuthi la ma-compact plate ahlangana kanjani namathuluzi okulinganisa i-granite yesimanje. Ama-digital height gauges, ama-optical comparator, ngisho nezingalo ze-CMM eziphathekayo zivame ukudinga ireferensi ezinzile, eyisicaba yokusetha noma yokuqinisekisa. I-mini plate esezingeni eliphezulu isebenza njengaleyo ankile, ukuqinisekisa ukuthi ukuhambisana akuphazamisi indawo engalingani noma engazinzile ngokushisa. Kwabachwepheshe basensimini abenza ukulungisa noma ukulinganisa endaweni, i-portable granite plate iba yindinganiso ehambayo—okuletha ukuzethemba kwelebhu ezindaweni ezikude.
Futhi ngokuphambene nenkolelo evamile, i-granite ayibuthakathaka uma isetshenziswa ngokoqobo. Nakuba ingaqhekeka uma ishaywa ngqo ngensimbi eqinile, imelana kakhulu nokugqoka kwansuku zonke. Ayigqwali, ayidingi ukugcotshwa ngamafutha, futhi ngeke iphenduke umswakama. Ngokunakekelwa okuyisisekelo—ukuhlanza njalo nge-isopropyl alcohol, ukugwema ukushayisana okukhulu, nokuyigcina iphansi—ingaletha amashumi eminyaka yesevisi ethembekile. Amapuleti amaningi amancane esiwabonile esebenza kusukela ekuqaleni kwawo-2000 asahlangabezana nezimpawu zawo zokuqala zokusicaba, ngenxa yokuphathwa kahle kanye nokulinganiswa kwetafula elingaphezulu okuhleliwe.
Uma ukhetha ipuleti elincane elingaphezulu, bheka ngale kobukhulu. Qinisekisa izinga lokusicaba ngesitifiketi sangempela—hhayi izimangalo zokumaketha. Qinisekisa ukuthi i-granite incane, ikhululekile ekucindezelekeni, futhi ayinazo izimfa noma imithambo ye-quartz engathinta ukuzinza. Abaphakeli abahloniphekile banikeza imibhalo ephelele, kufaka phakathi imephu yokusicaba ekhombisa ukuphambuka kokuya esiqongweni ngaphesheya kobuso. Ngezicelo ezibalulekile, cabanga ngamapuleti anezinombolo zochungechunge kanye nezitifiketi zokulinganisa ezilandelekayo ze-NIST ukuze kuhlangatshezwane nezidingo zokuhlolwa kwe-ISO 9001 noma i-AS9100.
Kwa-ZHHIMG, sikholelwa ukuthi ukunemba akufanele kugcinelwe amalebhu amakhulu anesikhala esingenamkhawulo. Yingakho sinikeza uhla lwezixazululo zepuleti elincane elinobuso obuncane—ngalinye lihlolwe ngazinye, lihlelwe ngokulandelana, futhi liqinisekiswe ngokwezindinganiso zomhlaba wonke. Sibambisana nama-workshops amakhulu ahlanganisa amasu endabuko okubopha ngesandla nokuqinisekiswa kwesimanje kwe-interferometric, okuqinisekisa ukuthi ipuleti ngalinye lihlangabezana nebanga lalo elishiwo. Futhi ngenxa yokuthi siyaqonda ukuthi ukulinganisa kuyaqhubeka, sinikeza isiqondiso ngezikhathi zokulinganisa kabusha kanye nezinsizakalo zokusekela ukugcina izindawo zakho zokubhekisela zithembekile iminyaka ezayo.
Ngoba ekugcineni, i-metrology ayimayelana nesilinganiso—imayelana neqiniso. Kungakhathaliseki ukuthi ulinganisa i-turbine blade noma i-micro-gear, idatha yakho iqotho njengobuso obakhelwe phezu kwayo. Ungavumeli ukulula konakalise ukuzethemba. Ipuleti elincane eligcinwe kahle, elisetshenziswa ngamathuluzi okulinganisa i-granite alinganisiwe futhi lisekelwa ukulinganiswa kwetafula elijwayelekile, akuyona into yokunethezeka—liyisisekelo sokulinganisa okuthembekile.
Ngakho-ke zibuze: uma ufunda ngokujulile namuhla, uyazi ukuthi ubuso bakho buyisicaba ngempela—noma uyaqagela? Kwa-ZHHIMG, sikusiza ukuthi ufake ukungabaza esikhundleni sokuqiniseka—i-micron eyodwa ngesikhathi.
