CNC machining ya ƙunshi yin amfani da na'ura mai sarrafa lamba (CNC) na kwamfuta don siffata da sake girman wani yanki, ko kayan aiki, ta hanyar cire abu ta atomatik.Yawanci, kayan da ake amfani da su filastik ne ko ƙarfe, kuma idan an gama cirewa, an samar da ƙãre samfurin ko samfur.
Wannan tsari kuma ana kiransa da masana'anta mai rahusa.Don injinan CNC, ana amfani da aikace-aikacen kwamfuta don sarrafa motsi na kayan aikin injin.
Nau'in kayan aikin injin CNC gama gari
Ayyukan injinan CNC sun haɗa da mafi yawan niƙa da juyawa, biye da niƙa, injin fitarwa na lantarki, da sauransu.
Milling
Milling shine aikace-aikacen kayan aiki na jujjuya zuwa saman kayan aiki, yana motsawa tare da gatura 3, 4 ko 5.Milling shine ainihin yanke ko datsa na kayan aiki, yana ba da damar haɗaɗɗen geometries da madaidaicin sassa da sauri da sauri daga ƙarfe ko thermoplastics.
Juyawa
Juyawa shine amfani da lathe don kera sassan da ke ɗauke da sifofin siliki.Kayan aikin yana jujjuyawa akan sandar kuma yana tuntuɓar ainihin kayan aikin juyawa don samar da gefuna masu zagaye, radial da ramukan axial, tsagi da tsagi.
Amfanin CNC machining
Idan aka kwatanta da mashin ɗin hannu na gargajiya, injinan CNC ya fi sauri.Muddin lambar kwamfutar ta daidai kuma ta dace da ƙira, samfurin da aka gama yana da daidaito mai girma da ƙananan kurakurai.
Masana'antar CNC shine ingantacciyar hanyar samar da samfuri cikin sauri.Hakanan za'a iya amfani da shi don kera samfuran amfani da ƙarshen amfani da abubuwan haɗin gwiwa, amma yawanci yana da tsada kawai a cikin ƙaramin ƙarami, gajeriyar samarwa.
Multi-axis CNC machining
CNC niƙa ya ƙunshi cire abu ta amfani da kayan aikin juyawa.Ko dai kayan aikin ya kasance a tsaye kuma kayan aikin yana motsawa kan kayan aikin, ko kuma kayan aikin ya shiga cikin injin a wani kusurwa da aka riga aka ƙaddara.Da yawan gatari na motsi na na'ura, da ƙarin hadaddun da sauri tsarin samar da shi ya zama.
3-axis CNC machining
CNC milling na axis uku ya kasance ɗaya daga cikin mafi mashahuri kuma tsarin aiwatar da injina.A cikin injina 3-axis, aikin aikin ya kasance a tsaye kuma kayan aikin juyawa yana yanke tare da gatari x, y, da z.Wannan nau'i ne mai sauƙi na CNC machining wanda ke samar da samfurori tare da tsari mai sauƙi.Bai dace da sarrafa hadadden geometries ko samfurori tare da hadaddun abubuwa ba.
Tun da kawai uku gatari za a iya yanke, machining kuma iya zama a hankali fiye da hudu ko biyar axis CNC, kamar yadda workpiece na iya bukatar da za a repositioned da hannu don samun da ake so siffar.
4-axis CNC machining
A cikin milling na CNC guda hudu, ana ƙara axis na huɗu zuwa motsi na kayan aikin yankan, ƙyale juyawa a kusa da x-axis.Yanzu akwai gatura huɗu - x-axis, y-axis, z-axis da a-axis (juyawa a kusa da axis x).Yawancin injunan CNC na 4-axis kuma suna ba da damar aikin aikin don juyawa, wanda ake kira b-axis, ta yadda injin zai iya aiki azaman injin niƙa da lathe.
4-Axis CNC machining shine hanyar da za ku bi idan kuna buƙatar tono ramuka a gefen yanki ko a saman silinda.Yana haɓaka aikin injina sosai kuma yana da daidaiton mashin ɗin.
5-axis CNC machining
Biyar-axis CNC milling yana da ƙarin axis na juyawa idan aka kwatanta da hudu-axis CNC.Hanya ta biyar ita ce jujjuyawa a kusa da y-axis, wanda kuma aka sani da b-axis.Hakanan ana iya jujjuya aikin aikin akan wasu injina, wani lokacin ana kiransa b-axis ko c-axis.
Saboda babban versatility na 5-axis CNC machining, ana amfani da shi don kera madaidaicin sassa.Kamar sassan likitanci na gabobi ko ƙashi na wucin gadi, sassan sararin samaniya, sassan titanium, sassan injinan mai da iskar gas, samfuran soja, da sauransu.
