I. Inkqubo yokuvelisa iGranite Straightedge
Ukuhlolwa nokusikwa kwezinto eziluhlaza
Iikhrayitheriya zokukhetha izinto: Igranite esemgangathweni ophezulu enobunzima obuyi-≥2.7g/cm³ kunye nesantya sokufunxwa kwamanzi esingaphantsi kwe-0.1% (njenge-"Jinan Green" evela eShandong kunye ne-"Black Gold Sand" evela eIndiya) kufuneka kukhethwe. Amasuntswana eeminerali kufuneka afane (amasuntswana e-quartz ≤2mm), angabi nazimfanta kunye neembobo, kwaye amatye afihlakeleyo afanele asuswe ngokufumanisa iziphene ze-X-ray.
Ukusika okurhabaxa: Sebenzisa isarha esijikelezileyo sedayimani ukusika isithuba esingenanto sibe sisithuba esingenanto esinobukhulu obuyi-5-10mm kunobungakanani bemveliso egqityiweyo. Impazamo yokuba tyaba komphezulu wokusika kufuneka ilawulwe ngaphakathi kwe-±0.5mm.
2. Unyango lokwaluphala
Ukwaluphala kwendalo: Beka umzimba oluhlaza emoyeni ovulekileyo kangangeenyanga ezi-6 ukuya kwezili-12. Ngenxa yomahluko phakathi kobushushu phakathi kwemini nobusuku kunye notshintsho kumswakama, ngaphezulu kwe-90% yoxinzelelo lwangaphakathi luyakhululwa ukuthintela ukuguquka kwesimo kwisigaba sokugqibela.
Ukuguga okwenziweyo (ukhetho): Abanye abavelisi basebenzisa isithando sobushushu esingaguqukiyo (100-150℃) iiyure ezingama-24 ukukhawulezisa ukukhululwa koxinzelelo, olufanele iiodolo ezingxamisekileyo, kodwa isiphumo siphantsi kancinci kunesokuguga kwendalo.
3. Ukusila okurhabaxa kunye nokulungiswa komphezulu wesalathiso
Ukusila nokubumba ngendlela erhabaxa: Sebenzisa ivili lokusila ledayimani elingama-200-400 ukuze usile indawo engenanto, ususe imigca yokusika, ulungise ukuba ithe tyaba ukusuka ku-±0.5mm ukuya ku-±0.1mm/m (100μm/m), uze umisele umphezulu obhekisa kuwo.
Unyango lomphezulu olungasebenziyo: Gcoba okanye ugqume imiphezulu esecaleni nasezantsi (njengokutshiza ipeyinti yokulwa nomhlwa) ukuthintela ukuqhekeka komphetho kunye nokwanda kokufunxwa komswakama.
4. Ukusila ngokuchanekileyo (inkqubo ephambili)
Ukutsiba ngokuchanekileyo kufezekiswa ngokusila ngokwemigangatho, okwahlulwe ngamanqanaba amathathu:
Ukusila okurhabaxa: Sebenzisa ii-brasives ze-mesh ezingama-400-800 (i-silicon carbide okanye i-diamond micro-powder) kunye neqonga lokusila le-granite ukulungisa uburhabaxa obuyi-±10μm/m, kunye noburhabaxa bomphezulu obuyi-Ra≤0.8μm.
Ukusila ngokuchanekileyo: Ngokutshintshela kwi-1200-2000 mesh abrasives kunye nokudibanisa ne-elektroniki level (ukuchaneka ±1μm/m) ukuze kujongwe ngexesha langempela, ukuthamba kuphuculwe ukuya kwi-±3μm/m, kwaye uburhabaxa bomphezulu iRa yi-≤0.4μm.
Ukugaya okucolekileyo kakhulu (isitshixo seemveliso ezichanekileyo kakhulu): Ngokusebenzisa umgubo omncinci we-W10-W5 (ubungakanani bamasuntswana 5-10μm) kunye nolwelo lokupholisha iikhemikhali, ngesenzo esiphindwe kabini "sokugrumba ngoomatshini + ukugrumba kweekhemikhali", ukuthamba kokugqibela kunokufikelela kwi-±1μm/m, kunye noburhabaxa bomphezulu we-Ra≤0.2μm.
5. Ukuchonga nokulungisa ngokuchanekileyo
Izixhobo zokufumanisa: I-interferometer yelaser (ukuchaneka ± 0.1μm) kunye nenqanaba le-elektroniki (isisombululo esingu-0.001mm/m) zisetyenziselwa ukufumanisa ubunzulu kunye nokuthe tye, kunye nokuzoba imephu yokusasazwa kweempazamo.
Ukulungiswa kwe-closed-loop: Ngokusekelwe kwidatha yokufumanisa, ukugaya okongezelelweyo kwendawo kwenziwa kwindawo enempazamo ephezulu ngomatshini wokugaya we-CNC de impazamo epheleleyo ilawulwe ngaphakathi koluhlu olujoliswe kulo.
6. Ukhuseleko kunye nokupakishwa komphezulu
Unyango olukhuselayo: Futha i-nano-scale silica coating (ubukhulu obuyi-5-10μm) kumphezulu ongqinisisiweyo, uze ufake umaleko we-wax ochasene nokugqwala kumphezulu ongasebenziyo ukuthintela ukufunxwa komswakama okanye i-oxidation ngexesha lokusetyenziswa ixesha elide.
Ukupakishwa ngokuchanekileyo: Ipakishwe kwiibhokisi zokhuni ezingashukumiyo kunye nee-desiccant. Ngexesha lokuthuthwa, umahluko wobushushu ulawulwa ngaphakathi kwe-±5℃ ukuze kuthintelwe ukuncitshiswa ngokuchanekileyo okubangelwa kukungcangcazela.
Ii. Imigangatho yoBuchule obuPhezulu kunye neMigangatho yoShishino
Ukuchaneka kwe-granite straightedge kusekelwe kwimpazamo ye-flatness njenge-core index. Ngokwemigangatho kazwelonke (GB/T 4977-2018) kunye nomgangatho wamazwe ngamazwe (ISO 2768-2), amanqanaba ayo okuchaneka kunye neeparameter ezihambelanayo zezi zilandelayo:
Iilebhu eziphambili zinokufikelela ekuchanekeni okupheleleyo:
Ngokusebenzisa iindlela zokugaya ezikumgangatho ophezulu (ezifana nokupholisha kwe-magneorheological kunye nokuguqulwa kwe-ion beam), ubucaba bezinye iimveliso eziphezulu bunokwahlulwa bube yi-±0.5μm/m (oko kukuthi, impazamo ngobude bemitha ayidluli kwi-0.5 micrometers), kusondela kwireferensi yeplane ye-optical-grade. Zisetyenziswa kakhulu kwiimeko ezichanekileyo kakhulu ezifana namaziko e-aerospace kunye ne-metrology.
Iii. Uthelekiso lwezinto ezichaphazela ukuchaneka
Isishwankathelo: Ukuchaneka okuphezulu kwe-granite straightedge kuxhomekeke kulawulo olupheleleyo lwenkqubo "yezinto eziluhlaza ezikumgangatho ophezulu + ukuguga okude kakhulu + ukugaya okunemigangatho + imeko enzima", apho inkqubo yokugaya ingundoqo yokuphumelela ngokuchanekileyo. Ngophuhliso lwetekhnoloji ye-nanofabrication, ukuchaneka kwayo kuya ngokuya kufikelela kwinqanaba le-sub-micron kwaye kube sisixhobo esingenakutshintshwa kwicandelo lokuvelisa izinto eziphezulu.
