Iitheyibhile zegranite ezithengiswayo azikho nje i-slabs enzima kwimilenze yensimbi-yisiseko esithe cwaka sesinyithi esichanekileyo. Sibukele iivenkile kuMntla Melika naseYurophu zithatha indawo yeebhentshi zentsimbi ezijijekileyo zafaka umphezulu wegranite-kwaye ngeentsuku ezingama-90, isivuno sazo sokuqala sitsibe umndilili we-12%. Ngoba? Kuba ukuzinza kwe-thermal kubaluleke ngaphezu kokuqina xa ubambe ± 0.005 ″ ukunyamezela kwizibiyeli ezinesitampu okanye iiphaneli ze-laser-cut chassis.
Kutheni iGranite—Kungeyiyo iNsimbi okanye iCast iron—Iphumelele kwiFabrication yeHlabathi yokwenyani
Uninzi lweenjineli zicinga ukuba "umsebenzi onzima" uthetha intsimbi eshinyeneyo. Kodwa ubunzima bodwa abuyeki ukungcangcazela. I-Granite ye-damping ratio yi-3-5 × ephezulu kunentsimbi etyhidiweyo kunye ne-10 × ephezulu kunentsimbi yesakhiwo. Kulingo lwethu lwasefektri, i-CNC-punch bracket ebekwe kwi-3 ″ yetafile emnyama yegranite ibonise i-68% yeresonance engaphantsi kwe-harmonic kwi-120 Hz kunokusetha okufanayo kwisiseko sentsimbi esi-2″. Oko kuguqulela ngokuthe ngqo kwincam ezisikiweyo ezicocekile, iindawo eziphinda-phindayo zemingxuma, kunye nemijikelo embalwa yokusebenza kwakhona.
I-Granite iphinda ixhathise i-thermal drift. Ivenkile yemveliso eqhelekileyo ibona ubushushu bomgangatho obuguqukayo obuyi-±8°C yonke imihla. Iibhentshi zentsimbi zanda/ikhontrakthi nge-12 µm/m·°C; igranite ihamba nje 0.5–0.8 µm/m·°C. Ngaphezulu komgangatho weemitha ezi-2, oko kukutshintsha kwe-0.24 mm kwintsimbi ngokuchasene ne-0.02 mm kwi-granite-ngokwaneleyo ukulahla i-CMM probe okanye ukulungelelanisa ukufa okugoba.
Asiyicebisi igranite ngeendawo ezinempembelelo ephezulu-ezifana nezikhululo zokubumba okanye imigangatho yocinezelo lwehydraulic. Kodwa kuhlolo, ukudibanisa, ukuxukuxa, kunye nomsebenzi woyilo oluchanekileyo? Akuxoxiswana. Kwaye ewe-iphatha ukuphathwa kwentsimbi yesiqhelo. Ibhentshi yethu yovavanyo iye yasinda kwimijikelo eli-1,200 yokurhuqa amashiti entsimbi egauji eli-12 eliqengqelekayo kumphezulu walo kunye ne-zero micro-scratches okanye edge chipping.
Eyona nto ifunwa ngabathengi—hayi oko kuthenjiswa ziincwadana
"Iitheyibhile zokwenziwa kweGranite ezithengiswayo" izintlu zihlala zifihla izinto ezibalulekileyo. Nantsi into eyahlula iibhentshi ezisebenzayo kubunzima bamaphepha abizayo:
Imiba yeBanga: Kuphela i-ASTM C615 yeBanga A okanye i-B ye-granite emnyama (umzekelo, i-Absolute Black, i-Baltic Brown) inikezela ukuxinana okuhambelanayo kunye ne-porosity ephantsi. Umgangatho worhwebo "ii-lookalikes zegranite" ziyaqhekeka phantsi komthwalo ozinzileyo wamanqaku. Ukunyamezelwa kokutya: Ungamkeli nantoni na engaphezulu kwe-±0.002″ ngaphezulu kwemitha e-1—okanye ±0.008″ ngaphezulu kweemitha ezi-4. Nantoni na ebanzi imema inxalenye egqwethekileyo ngexesha lokubamba. Ukunyusa ingqibelelo: Imilenze kufuneka ibotshwe ngokuthe ngqo etyeni-kungekhona kwizinto ezifakwe kwi-epoxy. Siye sabona iitafile ezintathu zingaphumeleli kwiinyanga ezili-18 kuba abavelisi basebenzisa iinkqubo ze-anchor ezincamathelayo kuphela. Ukugqitywa komphezulu: 60–80 igrit honed ilungile. Ipolishi yesipili ibonakalisa ukukhanya kodwa ifihla iimpawu zokuyila; i-coarse a finish irhintyela i-swarf kwaye inxiba ngokukhawuleza. Abanye abathengi bayabuza: "Ngaba ndingayifaka kuyo?" Hayi-awukwazi. Iintanda zeGranite ezingaphezu kwama-300°C. Kodwa wena unako faka i-welding jigs, i-clamps yomhlaba, kunye neziseko zemagneti ngokukhuselekileyo. Gcina nje imithombo yobushushu engaphezulu kwe-150 mm kude.
URhwebelwano lokwenyani lweHlabathi-Akukho zityatyekwe zeswekile
IGranite ayingomlingo. Inemida—yaye ukuzazi kuthintela iimpazamo ezinkulu.
Okokuqala: ubunzima bokuthumela. A umgangatho 2400 × 1200 × 76 mm itheyibhile inobunzima ~ 1,450 kg. Oko kufuna iidokhi zokulayishwa ezomeleziweyo, iijakhi zeepalethi ezilinganiswe i-2,000 kg, kunye nabasebenzi abane ubuncinane abaqeqeshelwe ukothula. Sakha sabona umthengi ezama ukuphakamisa enye ngefolokhwe—waqhawula amatye amabini aze aqhekeze ilitye ecaleni komgca wokuqhekeka kwendalo.
Okwesibini: ixesha lokufakela. Ukulinganisa igranite akufani nokubolisa intsimbi. Udinga iinyawo ezilungelelanisiweyo zokulinganisa, inqanaba le-machinist eqinisekisiweyo, kunye neeyure ezi-2-4 ubuncinane-nokuba kumgangatho wekhonkrithi. Inkxaso engalinganiyo ibangela ukuphuka koxinzelelo ngexesha.
Okwesithathu: ixabiso. Ewe, iitafile zegranite zibiza i-2.3 × ngaphezulu kunezinye iindlela zentsimbi enzima. Kodwa abathengi bethu banika ingxelo yentlawulo kwiinyanga ezili-14 ukuya kwezili-18 ngokucuthwa kwenkunkuma, ukuvunywa kwenqaku lokuqala ngokukhawuleza, kunye nesantya esisezantsi sokulinganisa i-metrology. Umthengisi weemoto omnye weTier-1 unqumle umjikelo wokuqinisekisa weCMM ukusuka ngeveki ukuya kwikota emva kokutshintsha.
Indlela Yokuchaza—Ngaphandle kokutshiswa
Musa ukuodola "itafile yegranite." Oda oku:
Izinto eziphathekayoI-ASTM C615 yeBanga A igranite emnyama, yombiwa eIndiya okanye eBrazil (iqinisekiswe ngesatifikethi sokusila) Imilinganiselo: Ubude obuchanekileyo × ububanzi × ubukhulu, kunye nokunyamezela ± 0.5 mm Ukucaba: Iqinisekisiwe ngokwe-ASME B89.3.7 nganye, ixelwe njengophambuko olukhulu kumphezulu ogcweleyo Ukunyuka: Iifakelo ezine ze-M16 ezinemisonto, i-40 mm ubunzulu, igxininise i-100 mm ukusuka kwikona nganye Gqiba: 70-grit honed, imiphetho lula ukuya 1.5 mm radius Amaxwebhu: Ingxelo yolungelelwaniso, isatifikethi semathiriyeli, kunye nephepha lokuhlola idimensional libandakanyiwe I-Botou Haijun Metal Products Co., Ltd. yakha iitheyibhile zokwenziwa kwegranite yesiko kwezi zinto zichanekileyo-kungekhona njengezongezo, kodwa njengenkqubo engaphantsi kobunjineli. Sizidibanisa kunye nezibiyeli zethu ezichanekileyo ezinesitampu, iinyawo zomgangatho wentsimbi engenastainless, kunye neepads zokulwa ukungcangcazela. Yonke itafile ihanjiswa ngedatha ye-QC elandelekayo-hayi nje isitikha.
Igama lokugqibela: Ukuchaneka kuqala phantsi kweenyawo
Ibhentshi yokusebenza ayenzi malungu. Kodwa umgangatho olawulwa kakubi uqinisekisa ukuguquguquka. Iitafile ezenziwe ngegranite ezithengiswayo zizisa i-ROI enokumetwa apho ukuphindaphindwa, ukuzinza kwe-thermal, kunye ne-flatness yexesha elide kuchaza impumelelo-hayi nje amandla. Ukuba inkqubo yakho ibambe iqine kune ±0.010 ″, ayinyamezeli incoko ebangelwa kukungcangcazela, okanye ifuna amashumi eminyaka wenkonzo ngaphandle kohlengahlengiso, igranite ayinyanzelekanga. Yisiseko.
