Ama-lathe ane-axis amabili aphatha imisebenzi eyisisekelo yesilinda njengokujika nokuthungela, angabizi ezingxenyeni ezincane eziphakathi nendawo zensimbi noma i-aluminium. Ama-axis amaningi (ama-axis angu-3-5+) engeza i-Y-axis kanye namathuluzi aphilayo wejometri eziyinkimbinkimbi ekusethweni okukodwa, okulungele izindiza.
Ama-lathe ohlobo lwaseSwitzerland, anama-headstock ashelelayo kanye nama-guide bushings, asebenza kahle kakhulu ezingxenyeni ezincane, ezinembayo ephezulu njengezikhonkwane zezokwelapha, ezisekela ama-axes afinyelela ku-10 e-titanium noma insimbi engagqwali. Ama-lathe aqondile aphatha izingxenye ezisindayo, ezinkulu ngokuqina, kanti avundlile anikeza ukuguquguquka kokususa ama-chip ngendlela ephumelelayo.
Ukusetha kuqala ngokufaka i-workpiece ngama-chuck noma ama-collet, kuqinisekiswa ukuhambisana ukuze kuvinjelwe ukuphelelwa yisikhathi. Amathuluzi afakwa ku-turrets, alinganiswe ukuphakama kanye ne-offset. Isivinini se-spindle (isb., 1000-4000 RPM) kanye nokuphakelwa (0.002-0.01 in/rev) kusethwa ngokusekelwe ezintweni ezibonakalayo. Izinhlelo ze-coolant kanye nama-chip conveyor alungiselelwe. Ukulinganisa ngezinkomba zokudayela kuqinisekisa ukunemba, okubeka isiteji somshini wokusebenza ongenaphutha.
Izinqubo Nemisebenzi Yomshini
Imisebenzi eyinhloko ekushicileleni insimbi ye-CNC ihlanganisa ukujika, lapho ithuluzi lisusa khona izinto ukuze lenze ububanzi noma ama-contour, lifinyelele ukubekezelelana okungu-±0.01 mm. Ukugoqa kunciphisa ubukhulu, ukuqeda kucwengisisa izindawo zibe yi-Ra 0.8 microns.
Iziphetho zesikwele ezibhekene, ezibalulekile ezindaweni ezisicaba zokuhlangana. Ukuhlanganisa izintambo kusikwa izintambo zangaphandle/zangaphakathi ngendlela efanayo, kubalulekile ezibophweni. Ukubhoboza nokubhoboza kudala/kukhulisa imigodi ngokunemba okungu-±0.005 mm.
Ukugoqa/ukuhlukanisa kwakha izimbobo noma ukuhlukanisa izingxenye, kuyilapho ukugoqa kunezela amaphethini okubamba. Ukuze kube nokunemba okwenziwe ngokwezifiso, ukulandelana kwemisebenzi kunciphisa ukuphambuka—isib., ukusekela izingxenye ezinde ngezinti zangemuva.
Amathuluzi abukhoma avumela izici ezingaphandle kwe-axis njengezikhala. Ukuqapha ngezinzwa kulungisa ukuguguleka, kuqinisekisa ikhwalithi. Ukususa ama-burbor kulandela, ngokuvamile okuzenzakalelayo, ukuze kube nemiphetho ebushelelezi. Lezi zinqubo ziletha izingxenye ezenziwe ngokwezifiso eziyinkimbinkimbi ngempumelelo.
Ukulawulwa Kwekhwalithi Nokuhlola
Ukulawulwa kwekhwalithi kubaluleke kakhulu, kusetshenziswa amathuluzi anjenge-micrometer, ama-caliper, kanye nemishini yokulinganisa eqondisanayo (i-CMM) ukuze kuqinisekiswe ubukhulu. Abahloli bokurhabaxa kwendawo bahlola ukuqeda, kuyilapho abaqhathanisi be-optical behlola amaphrofayili.
Ukulawulwa kwenqubo yezibalo (i-SPC) kuqapha ukuhlukahluka, kugcina amanani aphezulu e-Cpk. Ukuhlolwa kwangaphakathi kwenqubo kuthola izinkinga kusenesikhathi, ngokuhlolwa kwangemva komshini okuqinisekisa ukuhambisana.
Ezingxenyeni ezenziwe ngokwezifiso, ukulandeleka ngeziqinisekiso zezinto kanye nezinombolo zezindawo kubalulekile. Amaphutha avamile njenge-chatter noma ama-burrs ancishiswa ngokubukhali kwamathuluzi kanye nokunciphisa ukudlidliza. Le ndlela eqinile iqinisekisa imiphumela enembile kakhulu.
Izicelo Kuzo zonke Izimboni
Ezindiza, ama-lathe e-CNC akhiqiza izindlu ze-turbine kanye nezinamathiselo nge-titanium, okuqinisekisa amandla alula. Ukusetshenziswa kwezimoto kufaka phakathi imiphini namagiya ukuze kuhlale isikhathi eside.
Izinhlelo zezokwelapha ziveza izifakelo namathuluzi aneziphetho ezihambisana nemvelo. Umkhakha wamandla uyazuza kuma-valve nama-coupling ezindaweni ezinzima.
Amathuluzi ezimboni adala izibambi ezenziwe ngokwezifiso, kuyilapho izinto zikagesi zinezixhumi eziqondile. Izifundo zecala zibonisa izikhathi zokukhokha ezincishisiwe kanye nezindleko, zigqamisa ukuguquguquka kwezidingo ezenziwe ngokwezifiso ezinemba kakhulu.
Izinselele Nezixazululo
Izinselele zifaka phakathi ukuguguleka kwamathuluzi ezintweni eziqinile, okuxazululwa yizinto zokufaka i-carbide kanye nezinto zokupholisa. Ukudlidliza ezingxenyeni ezincane kuxazululwa nge-guide bushings.
Ubunzima bokuhlela ama-axis amaningi buncishiswa yi-CAM ethuthukisiwe. Ukuphambuka kwezinto ezivela ekushiseni kudinga ukuphakelwa okulawulwayo. Izixazululo ezifana nokwenza ngcono i-AI kanye nomshini wokuxuba ohlanganisiwe zithuthukisa ukuthembeka kwezingxenye ezenziwe ngokwezifiso.
Amathrendi Akusasa
Izitayela ezintsha zifaka phakathi i-AI yokuhlaziya okubikezelayo, ukuhlanganiswa okungeziwe kwe-hybrids, kanye nemikhuba eqhubekayo njengezinto ezisetshenzisiwe. Ukuqapha okukude okunikwe amandla yi-5G kanye ne-nanotechnology yokuthuthukiswa kwesithembiso esinembile kakhulu ekusetshenzisweni kwemishini ngokwezifiso.
Isiphetho
Umshini wokugaya insimbi we-CNC uguqula ukukhiqizwa kwezingxenye ezenziwe ngokwezifiso ngokunemba okuphezulu, uhlanganisa ukuzenzekela nobuciko. Kusukela ezindiza kuya kwezokwelapha, ukunemba kwawo kuqhuba ukusungula izinto ezintsha. Njengoba ubuchwepheshe buthuthuka, buhlala bubalulekile ekukhiqizeni okuthembekile nokusebenza kahle.
