Amathebula okwenziwa kwamatshe ayisisekelo esingaguquki sayo yonke indawo yokusebenzela yamatshe enemba okuphezulu—lapho amatafula egranite, izinto eziyize zemabula, nama-quartz slabs ahlangana nokubekezelelwa kanzima. Sibone izitolo zilahlekelwa u-12% wesivuno sezinto ezibonakalayo—hhayi ngenxa yephutha lomsebenzisi, kodwa kusuka ku-flexible yetafula ngaphansi kwama-slabs angu-300-kg ngesikhathi somzila we-CNC. Abanye bachitha imiphetho epholishiwe ngemva kwengxoxo encane edalwe ukudlidliza phakathi nokuphrofayili onqenqemeni. Lezi akuzona izingozi zethiyori. Ziyizindleko zansuku zonke ezigqitshwe ekusebenzeni kabusha, isikhathi sokuphumula, kanye nezimangalo zewaranti.
Kungani Ukuqina, Hhayi Usayizi Kuphela, Kuchaza Ithebula Lokwenziwa Kwetshe Langempela
Itafula lokwenziwa kwamatshe akulona ibhentshi lokusebenza. Kuyinkundla yebanga le-metrology okufanele ibambe ukucaba okungu-±0.05 mm kuyo yonke indawo ngenkathi idonsa imithwalo eguquguqukayo evela kumathuluzi edayimane, imibhobho yejethi yamanzi, namakhanda okupholisha. Ukwehluleka okuningi kulandelela ezintweni ezintathu ezinganakiwe: ukuchezuka kohlaka ngaphansi kwemithwalo e-cantilevered, ukukhukhuleka okushisayo kusuka emanzini apholisayo noma amashifu azungezile, nokuhlangana kwe-resonance phakathi kwetafula ne-CNC gantry.
Sihlole amatafula ayisishagalombili ohwebo ehlangothini ngehlangothi endaweni yase-Botou enama-interferometer alinganisiwe e-laser. Abadlali abaphezulu babelane ngesici esisodwa: amafreyimu ensimbi ashiselwe anezimbambo zangaphakathi—azikho izakhiwo ezingaphansi eziboshiwe, azikho izimbobo ezingenalutho. Amathebula akhiwe ngensimbi egoqelwe ebandayo (hhayi insimbi ethambile) agcina ukuqina kwe-dimensional ngemva kwamahora angu-72 okusika okumanzi okuqhubekayo. Amayunithi anefreyimu ye-aluminium abonise ukuhlehla okulinganisekayo (0.18 mm phakathi nendawo) ngemva kwamahora amane nje okusebenza kwebhuloho elingu-20-kW.
Isiphetho esingaphezulu sibaluleke kakhulu njengesakhiwo. I-3-micron Ra ground steel top imelana nokuphuma kwe-epoxy, ivimbela ukuvuza kwe-vacuum seal etsheni elinezimbotshana, futhi iqeda “izimpawu zesipoki” phakathi nokudlula kokugcina kokupholisha. Indawo engangomshini noma ependiwe ibamba udaka olulumayo, okusheshisa ukuguga futhi yethule umsindo we-harmonic ezinhlelweni ezinyakazayo.
Izici Ezine Ezingaxoxiswa Ngamathebula Okwenziwa Kwetshe Lemboni
Vacuum ubuqotho: Ubuncane bezindawo ezilawulekayo ezingama-24 ngazinye, ngayinye ilinganiselwe ≥65 kPa ukumuncwa kugwadule owomile kanye no-≥42 kPa ku-limestone emanzi—kuqinisekiswa ngokwe-ISO 21940-11 I-Dynamic damping: Ama-dampers e-viscous ahlanganisiwe noma izithambisi ezinkulu ezishuniwe ezicindezela amaza azwakalayo angaphansi kuka-120 Hz—uhlu olusebenzayo lwamatshe amaningi wokuphotha e-CNC Isinxephezelo esishisayo: Izinzwa ezishumekiwe ze-RTD eziphakela idatha yokulungiswa kwe-Z-axis yesikhathi sangempela kusilawuli se-CNC, okubalulekile ku-sub-0.1 mm kerf ukungaguquguquki kuwo wonke amashifu wamahora angu-12 I-anchoring ye-modular: Ama-T-slot rails ano-≤0.02 mm okuphindaphindwayo, ahambisana nezinhlelo ezijwayelekile zokubopha amatshe (isb., i-WNT, i-Biesse, i-Homag), hhayi ama-adaptha obunikazi Abanye baphikisa ngokuthi “noma iliphi itafula lensimbi eliqinile liyasebenza.” Kodwa silandele umqambi waseNyakatho Melika oshintshe kusukela kuthebula elijwayelekile elingu-4×3 m waya kuyunithi eklanyelwe inhloso: isikhathi sabo sokusika esimaphakathi nge-slab sehle ngo-19%, ukwakhiwa kabusha kwe-edge-polish kwehle kusuka ku-7.3% kuya ku-1.1%, futhi impilo ye-spindle inyuke ngo-44%. I-ROI yayingekho etafuleni-yayikunemba ekunike amandla.
Ukukhetha Okubalulekile Akukhona Ngezindleko—Kumayelana Nokuziphatha Kwesikhathi Eside Se-Metrological
Insimbi egoqiwe ebandayo (CRS) ibusa amatafula asebenza kahle kakhulu ngesizathu esihle: amandla ayo okukhiqiza (≥270 MPa), i-coefficient ephansi yokwandisa okushisayo (12 × 10⁻⁶ /°C), kanye nesakhiwo sokusanhlamvu kwe-isotropic simelana nokungqubuzana ngaphansi kokulayisha umjikelezo. Insimbi engagqwali inikeza ukumelana nokugqwala kodwa yethula ukukhukhuleka okushisayo okuphakeme okungu-30–40% kanye nesilinganiso esiphansi sokuqina kwesisindo—okuyinkinga eduze neziteshi zejethi zamanzi.
Sigwema ama-alloys e-aluminium kumalungu esakhiwo esiyinhloko. Nakuba ingasindi, i-6061-T6 inweba ngokushesha ngokuphindwe kabili njenge-CRS futhi ithambe ngaphezu kuka-150°C—ngaphakathi kwebanga lokushisa kokungqubuzana okuvela kumathuluzi edayimane. Iklayenti elilodwa e-Dubai libike ukuthi likhothame unomphela ngo-0.3 mm etafuleni le-aluminium ngemva kwezinyanga eziyisithupha lisebenza ehlobo, naphezu kwezimo zesitolo “ezilawulwa isimo sezulu”.
Wonke amatafula aqinisekisiwe kufanele aphumelele ukuhlolwa komthwalo wamahora angu-72: 1.5× olinganiselwe ubukhulu besisindo se-slab esisetshenziswa emakhoneni amane, bese kulinganiswa ukuchezuka kwensalela. Abakhiqizi abahloniphekile babhala lokhu—hhayi nje ukukufuna.
I-Botou Haijun Metal Products Co., Ltd.: Ukunemba Kobunjiniyela Kuyo Yonke Indawo Yokusekela
E-Botou Haijun Metal Products Co., Ltd., sakha amatafula okwenziwa kwamatshe lapho inhloso yobunjiniyela ihlangabezana neqiniso elibandayo. Ngokusekelwe eDolobheni lase-Botou—inhliziyo yobuchwepheshe bokugxiviza kwensimbi kanye neshidi lensimbi yase-China—siklama amathebula sisebenzisa izindlela zokulayisha ezilingiswa i-FEA, bese siyawaqinisekisa ngokuskena kwe-CMM nokuhlaziya i-modal. Amatafula ethu asebenzisa i-S355JR ozimele bensimbi abagoqelwe ngokubanda, iziqongo zensimbi eziphansi ze-EN 10025-2, kanye nama-vacuum manifolds ahlanganisiwe akhiwe ngomshini wasendlini ukuze avumelane ne-ISO 2768-mK.
Asiwathengisi amatafula. Siletha amapulatifomu e-metrological. Iyunithi ngayinye ithunyelwa ngemibiko yokuhlola egcwele: izilinganiso zokuhlanganisa ezindaweni ezingu-128, amalogi e-vacuum kubola amahora angu-8, namajika e-thermal drift ukusuka ku-−10°C kuya ku-+45°C. Amakhasimende ethu—kusuka kubakhiqizi bekhawundathophu yaseTexas kuya kumaphrosesa wemabula aseTurkey—adinga ukulungiswa kwenkundla eyiziro ngoba konke ukubekezelelana kukhiyiwe ngaphambi kokuthunyelwa.
amatafula okwakhiwa kwamatshe adinga okungaphezu kokuqina. Bafuna ukubikezelwa. Lapho i-quartz slab yakho elandelayo ihamba emisebenzini emihlanu yokukhiqiza, itafula alilibambi itshe—liphethe isithunzi sakho. Khetha isisekelo esingalokothi siyekethise.
