Phunzirani momwe mungasankhire mtundu woyenera wa spindle ndikuwonetsetsa kuti wanuCNC Machining Centerkapena pokhotakhota amayenda mozungulira bwino.#cnctechtalk
Kaya mukugwiritsa ntchito aCNC makina mpherondi chida chozungulira cha spindle kapena aChithunzi cha CNCyokhala ndi spindle yozungulira yozungulira, zida zazikulu zamakina a CNC zimakhala ndi masikelo angapo.Mtundu wa spindle wapansi umapereka mphamvu zambiri, pomwe mtundu wapamwamba umapereka liwiro lalikulu.Ndikofunikira kuwonetsetsa kuti makinawo akumalizidwa mkati mwa liwiro loyenera la spindle kuti akwaniritse zokolola zabwino kwambiri.Nawa malangizo asanu oti musankhe mtundu woyenera:
Opanga zida zamakina amasindikiza mawonekedwe a spindle m'mabuku awo ogwiritsira ntchito.Kumeneko mudzapeza rpm yocheperako komanso yochuluka pamtundu uliwonse, komanso mphamvu yoyembekezeredwa mumtundu wonse wa rpm.
Ngati simunaphunzirepo zambiri zofunikazi, nthawi yanu yozungulira mwina sinakwaniritsidwe.Kuti zinthu ziipireipire, mutha kukakamiza kwambiri injini ya spindle yamakina, kapena kuyimitsa.Kuwerenga bukhuli ndikumvetsetsa mawonekedwe a spindle kungakuthandizeni kukulitsa zokolola zamakina anu.
Pali njira ziwiri zosinthira masinthidwe: imodzi ndi makina opangira ma spindle drive motor, ina ndi makina oyendetsa makina.
Zoyambazo zimasintha mawonekedwe pakompyuta posintha ma windings a injini omwe amagwiritsa ntchito.Zosinthazi zimakhala pafupifupi nthawi yomweyo.
Dongosolo lokhala ndi makina opatsirana nthawi zambiri limayendetsa molunjika pamtunda wake wapamwamba kwambiri ndipo limatengera kufalikira kwapang'onopang'ono.Kusintha kwamitundu kumatha kutenga masekondi angapo, makamaka pamene spindle iyenera kuyima panthawiyi.
Kwa CNC, kusintha kwa ulusi wa spindle kumakhala koonekera, chifukwa liwiro la spindle limatchulidwa mu rpm, ndipo mawu a S a liwiro lodziwika bwino amapangitsanso makinawo kusankha masikelo oyenera.Tangoganizani kuti makina otsika kwambiri ndi 20-1,500 rpm, ndipo maulendo othamanga kwambiri ndi 1,501-4,000 rpm.Mukatchula mawu a S300, makinawo amasankha otsika.Mawu a S a S2000 apangitsa makinawo kusankha mtundu wapamwamba.
Choyamba, pulogalamuyi ingayambitse kusintha kosafunikira pakukula pakati pa zida.Pakutumiza kwamakina, izi zimawonjezera nthawi yozungulira, koma zitha kunyalanyazidwa chifukwa zimangowonekera pomwe zida zina zimatenga nthawi yayitali kuti zisinthe kuposa zina.Zida zogwiritsira ntchito zomwe zimafuna mtundu wofanana motsatizana zidzachepetsa nthawi yozungulira.
Chachiwiri, kuwerengetsera kwa spindle speed rpm kwa ntchito zokhotakhota zamphamvu kumatha kuyika spindle kumapeto kwenikweni kwa utali wa spindle, pomwe mphamvu imakhala yochepa.Izi zitha kukakamiza kwambiri spindle drive system kapena kuyambitsa injini ya spindle kuyimitsidwa.Wopanga mapulogalamu odziwa bwino adzachepetsa pang'ono liwiro la spindle ndikusankha liwiro lapamwamba kwambiri pamtunda wotsika, pomwe pali mphamvu zokwanira zopangira makinawo.
Pamalo otembenukira, kusintha kwa spindle kumachitika ndi M code, ndipo mtundu wapamwamba nthawi zambiri umadutsana ndi otsika.Kwa malo okhotakhota okhala ndi mipiringidzo itatu, zida zotsika zimatha kufanana ndi M41 ndipo liwiro ndi 30-1,400 rpm, zida zapakati zimatha kufanana ndi M42, liwiro ndi 40-2800 rpm, ndipo zida zapamwamba zimatha kufanana. mpaka M43 ndipo liwiro ndi 45-4,500 rpm.
Izi zimagwira ntchito potembenuza malo ndi ntchito zomwe zimagwiritsa ntchito liwiro lapamwamba.Liwiro la pamwamba likakhala losasintha, CNC imasankha mosalekeza liwiro (rpm) molingana ndi liwiro lapamwamba (mapazi kapena m / min) ndi mainchesi omwe akukonzedwa pano.
Mukayika feedrate pa revolution, liwiro la spindle limakhala lofanana ndi nthawi.Ngati mutha kuwirikiza kawiri liwiro la spindle, nthawi yofunikira kuti mugwire ntchito yofananira imadulidwa pakati.
Lamulo lodziwika bwino la kusankha kwa ma spindle ranges ndikumangirira motsika ndikumaliza patali.Ngakhale ili ndi lamulo labwino loonetsetsa kuti spindle ili ndi mphamvu zokwanira, sichita bwino poganizira liwiro.
Ganizirani zachidutswa cha mainchesi 1 chomwe chiyenera kukhala chopindika komanso chosinthika.Liwiro lovomerezeka la chida chovutitsa ndi 500 sfm.Ngakhale m'mimba mwake (inchi imodzi), idzatulutsa 1,910 rpm (3.82 nthawi 500 yogawidwa ndi 1).M'mimba mwake yaying'ono idzafuna liwiro lalikulu.Ngati wopanga mapulogalamu asankha kutsika pang'ono potengera zomwe wakumana nazo, spindle ifika malire a 1,400 rpm.Kungoganiza mphamvu zokwanira, ntchito roughing adzamalizidwa mofulumira mu osiyanasiyana apamwamba.
Izi zimagwiranso ntchito pazigawo zokhotakhota ndi zokhotakhota zomwe zimafuna kuthamanga kosalekeza pamwamba.Ganizirani movutikira kutembenuza tsinde la mainchesi 4 ndi mainchesi angapo, yaying'ono kwambiri yomwe ndi inchi imodzi.Tangoganizani kuti liwiro lovomerezeka ndi 800 sfm.Pa mainchesi 4, liwiro lofunika ndi 764 rpm.Mtundu wotsika udzapereka mphamvu zofunikira.
Pamene roughing ikupitirira, m'mimba mwake imakhala yaying'ono ndipo liwiro limawonjezeka.Pa mainchesi 2.125, makina abwino kwambiri amafunikira kupitirira 1,400 rpm, koma spindle idzafika pamtunda wa 1,400 rpm, ndipo njira iliyonse yowonongeka idzatenga nthawi yaitali kuposa momwe iyenera kukhalira.Kungakhale kwanzeru kusinthira kumtunda wapakati panthawiyi, makamaka ngati kusintha kwamtunduwu kumachitika nthawi yomweyo.
Pulogalamu ikalowa pamakina, nthawi iliyonse yopulumutsidwa mwa kudumpha kukonzekera kwadongosolo imatha kutayika mosavuta.Chonde tsatirani njira zomwe zili pansipa kuti muwonetsetse kuti zikuyenda bwino.
Magawo amauza CNC chilichonse chokhudza makina omwe akugwiritsidwa ntchito komanso momwe angagwiritsire ntchito zida zonse za CNC ndi ntchito zake.
