Imishini Yokugaya ye-CNC Eqondile vs Evundlile: Umehluko Oyinhloko, Okuhle Nokubi | Ukukhiqiza Okunembile kwe-SMS
Kwadalwa ngo 07.08
Ukugaya (milling) kuyinqubo yokukhipha izinto (subtractive manufacturing) esetshenziswa kakhulu ekukhiqizeni izingxenye zensimbi nezepulasitiki ezenziwe ngokwezifiso. Emisebenzini ejwayelekile yokugaya, ithuluzi lokusika elijikeleza ngesivinini esikhulu likhipha okungadingekile entweni eboshiwe, engashintshi ukuze kwenziwe izingxenye ezinobukhulu obunembile kanye nokuphethwa kwendawo okwenziwe ngokwezifiso.
Nakuba umgomo oyinhloko wokusebenza kokugaya uhlala ufana, imishini yokugaya yezimboni ihlukaniswa ngokuyinhloko ngokuma kwe-spindle yethuluzi lokusika: imishini yokugaya emile (vertical milling machines) kanye nemishini yokugaya evundlile (horizontal milling machines). Uhlobo ngalunye lomshini lunezici zomshini eziyingqayizivele kanye nezimo zokusebenza ezithile.
Konjiniyela bemishini emhlabeni wonke, abaphathi bokuthenga, kanye nabanikazi bemikhiqizo, ukukhetha umshini wokugaya ofanele kuthinta ngqo ukunemba kwengxenye, isikhathi sokukhiqiza, ukulawulwa kwesabelomali kanye nokungaguquguquki komkhiqizo weqoqo.
Kulo mhlahlandlela ophelele wemboni ovela ku-I-SMS Precision Manufacturing — umkhiqizi ochwepheshe wase-China we-CNC precision machining — sihlukanisa imishini yokugaya ye-CNC emile nengqimile, siqhathanisa umehluko wayo oyinhloko, sifingqa izinzuzo kanye nemikhawulo yayo, futhi sikusiza ukhethe isixazululo esihle sokugaya sama-oda akho we-prototype kanye nokukhiqizwa okuningi.
1. Uyini Umshini Wokugaya Ome Mpo?
Umshini wokugaya ome mpo ungumshini wokwenza izinto ovame kakhulu ezindaweni zokusebenza zomhlaba wonke. Isici sawo esiyinhloko i-spindle yokusika efakwe mpo, ebheke phansi etafuleni lomshini. Umsiki ome mpo ucindezela phansi ucezu olungashintshi futhi ususe izinto ngokuqinile ngokwemidwebo ye-2D kanye namafayela e-CAD e-3D.
Kunezinhlobo ezimbili eziyinhloko zomshini wokugaya oqondile osetshenziswa kakhulu ekukhiqizeni kwezimboni:
1.1 Imishini Yokugaya Yomshini Wokugaya
Imishini yokugaya i-turret iklanyelwe ukwenza izingxenye ezincane ezinembayo. Kulo mshini, i-spindle ebamba ithuluzi ihlala inganyakazi. Esikhundleni salokho, itafula lokusebenza le-turret lihamba ngokukhululeka kokubili okuvundlile nokuqondile ukuze kuqedwe ukondla nokususwa kwempahla. Ilungele ukusikwa okulula, amabhachi amancane okucubungula izingxenye ezilula.
1.2 Imishini Yokugaya Yombhede
Imishini yokugaya yombhede iwuhlobo oluvame kakhulu lokugaya okuqondile ezindaweni zokusebenza zendabuko neze-CNC zanamuhla. Ngokungafani nemishini ye-turret, itafula layo lokusebenza lihamba okuvundlile kuphela, kuyilapho i-spindle iqhuba ithuluzi lokusika ukuthi lihambe liye phezulu naphansi okuqondile.
Ukunyakaza okuhleliwe kwe-spindle nombhede womshini kwenza kube lula ukwenziwa okusheshayo kwemisele, izimbobo, ama-counterbore nezinye izici ezinhlangothi olulodwa zomshini. I-SMS Precision ihlinzeka ngamasethi aphelele emishini yokugaya ye-CNC enembile ephezulu ukuze kwenziwe ama-prototype asheshayo kanye nama-oda enani elincane ezingxenyeni ezenziwe ngokwezifiso.
2. Iyini Umshini Wokugaya Ovundlile?
Imishini yokugaya evundlile inomqondo oyisisekelo ofanayo wokusebenza nemishini yokugaya emi mpo: ingxenye yomsebenzi iboshwe ngokuqinile futhi imile, futhi ithuluzi lokusika elijikelezayo lisusa izinto ezingasasebenzi. Umehluko oyisisekelo obonakalayo ukuhlelwa kwe-spindle ethwele ngokuvundlile kanye nethuluzi lokusika, elihambisana nendawo yetafula lomsebenzi.
Lolu hlobo lomshini lwakhelwe ukwenza imisebenzi enzima yokugaya, izingcezu zomsebenzi ezinkulu kanye nemisebenzi yokusika ejulile. Ukwakheka kwawo kwengxenye engaphezulu kunikeza amandla amakhulu okusika kanye nejubane elikhulu lokususa izinto. Imishini yokugaya evundlile yasendulo yayinenkinga yokungabi nembili kahle ekwenzeni umsebenzi; nokho, ubuchwepheshe besimanje be-CNC bususile ngokuphelele le nkinga yokungabi nembili.
Into ephawuleka kakhulu ngemishini yokugaya evundlile ye-CNC amandla ayo okwenza umsebenzi ema-engeli amaningi. Uma ihlanganiswa netafula elijikelezayo elisebenza kuzo zonke izinhlangothi, ithuluzi lokusika lingafinyelela engxenyeni yomsebenzi kunoma iyiphi i-engeli. Lokhu kwenza imishini yokugaya evundlile ifaneleke kakhulu ezingxenyeni eziyinkimbinkimbi ezingajwayelekile ezingenakwenziwa ngokugaya okuqondile ekuhlelweni okukodwa.
3. Okuhle nokubi Kwemishini Yokugaya Eqondile Ye-CNC
I-CNC vertical machining centers ibusa izimakethe zokwenziwa ngokwezifiso ezinamabhantshi amancane naphakathi, ngenxa yesakhiwo sayo esilula kanye nomkhawulo ophansi wokusebenza. Amandla ayo kanye nobubi bayo buvela ikakhulukazi esakhiweni se-spindle kanye nejometri yamathuluzi.
