Iitheyibhile zokwenziwa kwegranite zi-ankile iindibano zocweyo zamatye ezichanekileyo-kungekhona nje ngomphezulu wokwenziwa komsebenzi, kodwa njengamaqonga alungelelanisiweyo apho inyaniso enomlinganiselo idibana nokuziphatha okuphathekayo. Siye sabona iivenkile zilahlekelwa yi-12% ye-slab isivuno kwi-table flex phantsi kwemithwalo ye-gantry ye-CNC; abanye balahle imiphetho emi-3–4 ngosuku ngenxa yokuba ukubamba kwe-vacuum akuphumelelanga kwibha ye-0.8. Olu ayilulo unyamezelo lwethiyori. Ziilahleko zemihla ngemihla ezifakwe kwiincwadi zamanqaku ezikumgangatho wevenkile kulo lonke elaseOhio, eOntario, naseOmsk.
Kutheni IGranite—Ingeyontsimbi okanye Ikhonkrithi—Iphumelela Ukwenza Ilitye
Amandla oxinzelelo lweGranite adlula i-200 MPa. I-coefficient yayo yokwandisa i-thermal ihlala kwi-0.000008 / ° C-ngaphantsi kwesiqingatha se-aluminium, enye yesihlanu yentsimbi epholileyo. Xa ibhulorho ye-CNC ihamba nge-1.2 m/s phezu kobude obuziimitha ezi-3, nokuba yi-0.02 mm ye-thermal drift shifts cut engile ngaphaya kwe-±0.15 ° ukunyamezelana. Silinganise le ndawo kwisayithi: i-30 ° C i-ambient swing ibangele i-0.07 mm i-deflection kwi-table yensimbi engama-40 mm-kodwa kuphela i-0.013 mm kwisiseko se-granite se-120 mm. Loo mahluko wahlula ukuphindaphinda komphetho ekusebenzeni kwakhona.
Iitafile zokwenyani zegranite zisebenzisa i-quarried, iibhloko ezithomalalisa uxinzelelo-ezingaphoswanga i-polymer composites ezenza ilitye. Ukwakhiwa kweenkozo kufuneka kube yinto efanayo, kungabikho micro-fractures eziwela i-surface plane. Sivavanya yonke i-slab nge-ultrasonic pulse-echo phambi komatshini: isantya sesandi esingaphantsi kwe-3,200 m/s sibonakalisa i-voids yangaphakathi. Kuphela amacwecwe abetha i-3,450–3,600 m/s enza uluhlu lwethu lokugqibela lokusikwa.
Ukunyaniseka kwevacuum kubaluleke ngaphezu kwamandla akrwada okufunxa. Itheyibhile elinganiswe ngama-95 kPa ayithethi nto ukuba ijeometry yetshaneli ivuza ngama-70 kPa. Inkqubo yethu yokuqinisekisa imilinganiselo yokubola: uxinzelelo kufuneka lubambe ≥85 kPa imizuzu eyi-10 emva kokutywinwa kwazo zonke izibuko. Obo buncinci bokumelana ne-lateral shear ngexesha lokubandakanya isixhobo sedayimane.
Iimpawu ezine ezingaxoxisaniyo (Ixhaswa yiDatha yoMmandla)
Emva kophicotho lwezixhobo zokuyila ezingama-47 kulo lonke elaseMntla Melika naseYurophu, siye sachitha izinto ezine ezahlulahlula iitafile ezisebenzayo kumatyala abiza imali eninzi:
Ukunyamezela kwe-flatness ≤0.05 mm / m-ukuqinisekiswa ngeeflethi ze-optical kunye ne-interferometry, kungekhona i-straightedges Igridi ye-T-slot edibeneyo nge-20-mm pitch, enziwe ngomatshini ukuya ku-±0.02 mm ukuchaneka kwendawo Iindawo zokufunxa iimodyuli (ubuncinci be-16 ngetafile ye-3 × 2 m), nganye ineevalve zokuzihlukanisa ezizimeleyo Ukuzinzisa ubunzima bobushushu: Ubuncinci be-120 mm ubukhulu kwiitafile ezingaphantsi kwe-4 m ubude; 150 mm kwiifomathi ezinkulu Omnye umxhasi eWisconsin utshintshe itafile yekhonkrithi eqiniswe ngentsimbi "yepremium" emva kweenyanga ezintandathu. Umzila wabo we-CNC waqala ukukhukuliseka phakathi. Ulungelelwaniso lweLaser luveze i-0.18 mm sag ngapha kwe-Y-axis-ebangelwa kukufunxa ukufuma ukudumba i-substrate. IGranite yawuphelisa loo mahluko. Isivuno sabo seveki yokuqala sitsibe nge-8.3%.
Ingqibelelo yezinto eziphathekayo ayikhethi-iyakulinganiswa
I-Botou Haijun Metal Products Co., Ltd. ayenzi iitafile zegranite. Kodwa sibonelela ngezixhobo zetsimbi ezibalulekileyo ezenza ukuba zisebenze: ukufakwa komatshini we-T-slot ochanekileyo, i-vacuum manifolds yensimbi engenastainless, kunye ne-CNC-bent yenkxaso yefreyimu ezenzelwe i-zero resonance kwi-120 Hz-eyona ndawo ibalaseleyo yeesarha zamatye.
Amacandelo ethu afumana ukuqinisekiswa okumanqanaba amathathu: ukuqinisekiswa kwezinto eziluhlaza (iingxelo zovavanyo lokusila ze-SS304/316L), uhlolo lwe-CMM lwasemva komatshini (± 0.01 mm kuzo zonke iindawo zokubeka indawo), kunye nokuhamba ngebhayisikile ye-vacuum esebenzayo (imijikelo eyi-10,000 kwi-1.2 yoxinzelelo lokwahlukana kwebar). Silahla i-4.7% yeebhilidi ezingenayo ezisekelwe kuvavanyo lwe-tensile yodwa-kuba amandla emveliso ngaphantsi kwe-520 MPa ingozi yokuguqulwa kwe-deformation phantsi kwemithwalo yokuqhawula.
Abanye abaqulunqi bafaka iitafile ngokuthe ngqo kwimigangatho yekhonkrithi. Umbono ombi. Siye sabhala ukuhanjiswa kwe-vibration yomgangatho okhulisayo kwi-18 Hz-ehambelana nobuninzi bendalo beenkqubo ezininzi ze-gantry. Iingcebiso zethu? Ukuzimela yedwa kunye neepads ze-neoprene (u-Shore A 60 hardness) kwaye uqinisekise ukufuduka <0.005 mm i-peak-to-peak usebenzisa i-laser Doppler vibrometry.
Ukukhetha iTheyibhile yakho: Buza le mibuzo mihlanu phambi kokusayina
Ngaphambi koku-odola, buza umthengisi wakho:
Ngaba unokubonelela ngeemephu ze-interferometric flatness-hayi nje "ngaphakathi kwamabango"? Ngowuphi owona mgangatho wokubola kwevacuum kwindawo nganye, elinganiswa ngokwe-ISO 10292? Ngaba i-T-slot channels CNC-eyenziwe kwi-setup enye-okanye i-welded kunye nomhlaba? Uqinisekisa njani ukuzinza kwe-thermal? (Buza i-delta-T vs. iigrafu zokutenxa kumphezulu.) Leliphi i-slab elide eliqhubekayo elicutshungulwe kolu lungelelwaniso lwetafile-kwaye yintoni ukunyamezela komphetho okuphunyeziweyo? Siye sabona iikowuti zilahla i-22% xa abathengi bafuna idatha yokwenyani endaweni yeencwadana. Omnye umsasazi waseYurophu watshintsha ababoneleli emva kokufumanisa itafile yabo "echanekileyo" isetyenziswe i-quarry offcuts egciniweyo-ebonakala njengeepateni zengqolowa ezingahambelaniyo phantsi kokuhlolwa kwe-LED ye-100-lux.
Iitafile zokwenza i-Granite aziphuculi ukusika-ziyenza ikwazi. Baguqula ikhowudi ye-CNC ibe yinyaniso ebonakalayo. Ukuba umsebenzi wakho olandelayo ufuna ±0.05 mm edge consistency kwi-3 cm quartzite, qala ngeqonga elibambekayo ngelixa yonke enye into ihamba. Elo qonga liqala ngegranite, ukucaca okungqiniweyo, kunye nengqibelelo yevacuum onokuyilinganisa-ungacingeli.
