CNC Machining a zigawo pulasitiki

NgakhaleCNC makinambali za pulasitiki ndizosavuta kudula, zimakhalanso ndi zovuta zina, monga mapindikidwe osavuta, matenthedwe otsika kwambiri, komanso okhudzidwa kwambiri ndi mphamvu yodula, kulondola kwake kokonzekera sikumatsimikiziridwa, chifukwa n'kosavuta kukhudzidwa ndi kutentha, komanso kumakhala kosavuta kutulutsa mapindikidwe mu processing, koma tili ndi njira zothetsera izo.CNC Machining a zigawo pulasitiki:

1. Kusankha zida:

• Popeza zinthu zapulasitiki ndizofewa, zida zakuthwa ziyenera kusankhidwa. Mwachitsanzo, kwa ma prototypes apulasitiki a ABS, zida za carbide zokhala ndi m'mphepete lakuthwa zimatha kuchepetsa misozi ndi ma burrs pakukonza.

• Sankhani zida kutengera mawonekedwe ndi mwatsatanetsatane zovuta za prototype. Ngati chojambulacho chili ndi zomangira zolimba mkati kapena mipata yopapatiza, maderawa ayenera kukonzedwa bwino pogwiritsa ntchito zida zing'onozing'ono monga mphero zazing'ono za mpira.

2. Kudula zoikamo:

•Kudula liwiro: Malo osungunuka a pulasitiki ndi ochepa. Kudula mwachangu kumatha kuyambitsa pulasitiki kutenthedwa ndikusungunuka. Nthawi zambiri, kuthamanga kwachangu kumatha kukhala kofulumira kuposa kupangira zida zachitsulo, koma ziyenera kusinthidwa kutengera mtundu wapulasitiki ndi zida. Mwachitsanzo, pokonza ma prototypes a polycarbonate (PC), kuthamanga kwachangu kumatha kukhazikitsidwa mozungulira 300-600m/min.

• Kudya liwiro: Moyenera chakudya liwiro akhoza kuonetsetsa processing quality. Kuchuluka kwa chakudya kungachititse kuti chidacho chikhale ndi mphamvu yodula kwambiri, zomwe zimapangitsa kuchepa kwa khalidwe lapamwamba; chochepa kwambiri chakudya mlingo kuchepetsa processing dzuwa. Kwa ma prototypes wamba apulasitiki, liwiro la chakudya litha kukhala pakati pa 0.05 - 0.2 mm / dzino.

•Kudula kwakuya: Kuzama kwa kudula kusakhale kozama; Apo ayi, mphamvu zazikulu zodula zidzapangidwa, zomwe zingathe kusokoneza kapena kusokoneza chithunzicho. Muzochitika zodziwika bwino, tikulimbikitsidwa kuti kuya kwa kudula kumodzi kumayendetsedwa pakati pa 0.5 - 2mm.

3. Kusankha njira yotsekera:

•Sankhani njira zoyenera zomangira kuti musawononge mawonekedwe. Zida zofewa monga ma rabara atha kugwiritsidwa ntchito ngati cholumikizira pakati pa clamp ndi prototype kuteteza kuwonongeka kwa clamping. Mwachitsanzo, pomangirira chithunzicho mu vise, kuyika mphira pansagwada sikumangolimbitsa chithunzicho motetezeka komanso kumateteza pamwamba pake.

• Mukamangirira, onetsetsani kukhazikika kwa chithunzicho kuti musasunthike panthawi yokonza. Kwa ma prototypes osawoneka bwino, zosintha mwamakonda kapena zophatikiza zitha kugwiritsidwa ntchito kuti zitsimikizire malo awo osakhazikika pakukonza.

4. Kukonza ndondomeko ya ndondomeko:

•Nthawi zambiri, makina okhwima amachitidwa poyamba kuti achotse ndalama zambiri, ndikusiya pafupifupi 0.5 - 1 mm kuti amalize. Roughing angagwiritse ntchito magawo akuluakulu odula kuti apititse patsogolo kukonza bwino.

• Mukamaliza, chidwi chiyenera kuperekedwa pakuwonetsetsa kulondola kwapang'onopang'ono komanso mawonekedwe apamwamba a prototype. Kwa ma prototypes omwe ali ndi zofunikira zapamwamba zapamwamba, njira yomaliza yomaliza imatha kukonzedwa, monga mphero ndi liwiro laling'ono la chakudya, kudula pang'ono, kapena kugwiritsa ntchito zida zopukutira pochiza pamwamba.

5. Kugwiritsa ntchito kozizira:

•Mukamakonza ma prototypes apulasitiki, samalani mukamagwiritsa ntchito zoziziritsa kukhosi. Mapulasitiki ena amatha kuchitapo kanthu ndi zoziziritsa kukhosi, choncho sankhani zoziziritsira zoyenera. Mwachitsanzo, potengera za polystyrene (PS), pewani kugwiritsa ntchito zoziziritsa kukhosi zomwe zimakhala ndi zosungunulira zina.

•Ntchito zazikulu za choziziritsa kuzizira ndi kuziziritsa ndi kuthira mafuta. Panthawi yokonza makina, choziziritsa choyenera chimatha kuchepetsa kutentha, kuchepetsa kuvala kwa zida, komanso kukonza makina abwino.
