CNC machining izwi rakajairika rinoshandiswa kune akasiyana machining application.“CNC” inomirira kuti Computer Numerical Controlled uye inoreva kurongeka kwemuchina, zvichiita kuti muchina uite mabasa akawanda neudzori hushoma hwevanhu.CNC machining ndiko kugadzirwa kwechikamu uchishandisa CNC inodzorwa muchina.Iro izwi rinotsanangura huwandu hweanobvisa ekugadzira maitiro apo zvinhu zvinobviswa kubva kune stock workpiece, kana bara, kuburitsa chikamu chakapedzwa chikamu.Kune marudzi mashanu akajairika eCNC machining anoitwa ne5 marudzi akasiyana eCNC michina.
Aya maitiro anoshandiswa mune akawanda maapplication kune akasiyana maindasitiri anosanganisira ekurapa, aerospace, maindasitiri, mafuta negasi, hydraulics, pfuti, etc. A zvakasiyana-siyana zvinhu zvinogona CNC machined kusanganisira simbi, mapurasitiki, girazi, composites uye huni.
CNC machining inopa akawanda mabhenefiti pamusoro pekugadzira pasina CNC programmable kugona.Yakanyanya kuderedzwa kutenderera nguva, yakagadziridzwa kupera uye akawanda maficha anogona kupedzwa panguva imwe chete uye anogona kuvandudza mhando uye kuenderana.Inobatsira kune yepakati uye yakakwirira vhoriyamu zvinodiwa uko kurongeka uye kuomarara kunodiwa.
#1 - CNC Lathes uye Turning Machines
CNC lathes uye machina ekutendeuka anoratidzirwa nekugona kwavo kutenderera (kutendeuka) zvinhu panguva yekushanda kwemuchina.Zvishandiso zvekucheka zvemichina iyi zvinodyiswa mumutsara wekufamba pamwe neiyo inotenderera bhaa stock;kubvisa zvinhu zvakatenderedza denderedzwa kusvika iyo dhayamita inodiwa (uye chimiro) yawanikwa.
A subset of CNC lathes CNC Swiss lathes (anova ari mhando muchina Pioneer Service inoshanda).Iine CNC Swiss lathes, iyo bhaa yezvinhu inotenderera uye inotsvedza axially kuburikidza negwara rekugezera (muchina wekubata) mumushini.Izvi zvinopa tsigiro iri nani yezvinyorwa semichina yemidziyo iyo chikamu chinoratidzira (zvichikonzera zvirinani/kusimba kushivirira).
CNC lathes uye machina ekutenderedza anogona kugadzira emukati nekunze maficha pane icho chikamu: akadhirowa maburi, mabhori, mabroache, maburi akadzokororwa, slots, taper, matepi uye tambo.Zvikamu zvakagadzirwa paCNC lathes uye nzvimbo dzekutendeuka zvinosanganisira screws, mabhoti, shafts, poppets, nezvimwe.
#2 - CNC Milling Machines
CNC milling machines inoratidzirwa nekugona kwavo kutenderedza maturusi ekucheka vachibata zvinhu zvebasa/block stationary.Vanogona kuburitsa maumbirwo akasiyana siyana anosanganisira kumeso-akagayiwa maficha (akadzika, akafuratira nzvimbo uye mhango muworkpiece) uye peripheral milled features (yakadzika mhango senge slots neshinda).
Zvimiro zvinogadzirwa paCNC milling muchina zvinowanzoita sikweya kana rectangular zvimiro zvine akasiyana maficha.
#3 - CNC Laser Machina
CNC laser michina ine yakanongedza router ine yakanyanya kutariswa laser danda iyo inoshandiswa kunyatso kucheka, kucheka kana kunyora zvinhu.Iyo laser inopisa zvinhu uye inoita kuti inyunguduke kana kunyungudika, ichigadzira kucheka mune izvo zvinhu.Kazhinji, zvinhu zvacho zviri mushizha fomati uye danda relaser rinofamba richidzoka nepamusoro pamusoro pezvinhu kugadzira kucheka chaiko.
Iyi nzira inogona kuburitsa huwandu hwakakura hwemagadzirirwo kupfuura akajairwa kucheka michina (lathes, turning centers, mill), uye kazhinji inoburitsa kucheka uye / kana mipendero isingadi mamwe maitiro ekupedzisa.
CNC laser engravers inowanzo shandiswa kune chikamu chekumaka (uye kushongedzwa) kwezvinhu zvakagadzirwa nemichina.Semuenzaniso, zvinogona kunetsa kugadzira logo uye zita rekambani kuita CNC yakatendeuka kana CNC milled chikamu.Nekudaro, laser engraving inogona kushandiswa kuwedzera ichi kune chikamu kunyangwe mushure mekuita machining apera.
#4 - CNC Magetsi Anoburitsa Machina (EDM)
A CNC electric discharge muchina (EDM) inoshandisa zvakanyanya kudzorwa magetsi sparks kushandura zvinhu kuita chimiro chaunoda.Inogona zvakare kunzi spark eroding, kufa kunyura, spark machining kana kupisa waya.
Chimwe chikamu chinoiswa pasi pewaya ye electrode, uye muchina wacho wakarongwa kuti ubudise kubuda kwemagetsi kubva pawaya iyo inoburitsa kupisa kwakanyanya (kusvika 21,000 madhigirii Fahrenheit).Izvo zvinhu zvinonyungudutswa kana kunyungudutswa nemvura kuti zvigadzire chimiro chaunoda kana chimiro.
EDM inowanzoshandiswa pakugadzira chaiyo microholes, slots, tapered kana angled features uye zvakasiyana-siyana zvezvimwe zvakanyanya-zvakaoma muchikamu kana workpiece.Inowanzo shandiswa kune simbi dzakaomesesa izvo zvingave zvakaoma kumichina kune chishuwo chimiro kana chimiro.Muenzaniso mukuru weiyi ndiyo yakajairika giya.
#5 - CNC Plasma Kucheka Machina
CNC plasma-kucheka michina inoshandiswawo kucheka zvinhu.Zvisinei, vanoita basa iri vachishandisa plasma ine simba guru (electronic-ionized gas) torch iyo inodzorwa nekombiyuta.Zvakafanana mukushanda kwechibatiso cheruoko, chine gasi chemwenje chinoshandiswa kugadzira (kusvika 10,000 madhigirii Fahrenheit), mamwenje eplasma anosvika ku50,000 madhigirii Fahrenheit.Iyo tochi yeplasma inonyungudika kuburikidza neworkpiece kugadzira kucheka mune izvo zvinhu.
Sezvinodiwa, chero nguva CNC plasma yekucheka ichishandiswa, zvinhu zviri kucheka zvinofanirwa kuve zvine magetsi.Zvishandiso zvakajairika isimbi, simbi isina tsvina, aruminiyamu, ndarira nemhangura.
Precision CNC machining inopa huwandu hwakasiyana hwekugadzira hunyanzvi hwezvikamu uye kupedzisa munzvimbo yekugadzira.Zvichienderana nenharaunda yekushandiswa, zvinhu zvinodikanwa, nguva yekutungamira, vhoriyamu, bhajeti uye maficha anodiwa, kazhinji pane yakanakisa nzira yekuunza yaunoda mhedzisiro.
