Kuti muchotse kubowola kwa CNC popanda kuwonongeka, onetsetsani kuti kuya kwake sikudutsa katatu kapena kanayi. m'mimba mwake. Komanso, chepetsani kuchuluka kwa chakudya pamene kubowola kwatsala pang'ono kutuluka.
Njira Zina Zopangira Pulasitiki Machining
Kupatula CNC pulasitiki mbali Machining, njira zina mofulumira prototyping akhoza kukhala m'malo. Zodziwika bwino ndi izi:
Jekeseni Kumangira
Iyi ndi njira yotchuka yopanga zinthu zambiri zogwirira ntchito ndi pulasitiki. Kuumba jekeseni kumaphatikizapo kupanga nkhungu kuchokera ku aluminiyamu kapena chitsulo kutengera zinthu monga moyo wautali. Pambuyo pake, pulasitiki yosungunuka imalowetsedwa mu nkhungu, kuzizira, ndi kupanga mawonekedwe ofunikira.
Kumangira jakisoni wa pulasitiki ndikoyenera popanga ma prototyping ndikupanga magawo enieni. Kupatula apo, ndi njira yotsika mtengo yoyenera magawo okhala ndi mapangidwe ovuta komanso osavuta. Kuphatikiza apo, magawo opangidwa ndi jakisoni safuna ntchito yowonjezera kapena chithandizo chapamwamba.
Kusindikiza kwa 3D
Kusindikiza kwa 3D ndi njira yodziwika kwambiri yopangira ma prototyping omwe amagwiritsidwa ntchito m'mabizinesi ang'onoang'ono. Njira yopangira zowonjezera ndi chida chofulumira cha prototyping chomwe chimakhala ndi matekinoloje monga Stereolithography (SLA), Fused Deposition Modeling (FDM), ndi Selective Laser Sintering (SLS) yomwe imagwiritsidwa ntchito popanga ma thermoplastics monga nayiloni, PLA, ABS, ndi ULTEM.
Ukadaulo uliwonse umaphatikizapo kupanga mitundu ya digito ya 3D ndikumanga magawo omwe amafunidwa mosanjikiza ndi wosanjikiza. Izi zili ngati makina apulasitiki a CNC, ngakhale amawononga zinthu zochepa, mosiyana ndi zomalizazi. Kuphatikiza apo, zimathetsa kufunikira kwa zida ndipo ndizoyenera kupanga magawo okhala ndi mapangidwe ovuta.
Kutaya kwa Vacuum
Kuponyera vacuum kapena kuponyera kwa polyurethane / urethane kumaphatikizapo nkhungu za silicon ndi utomoni kuti apange chithunzi chaukadaulo. Njira yopangira prototyping yofulumira ndiyoyenera kupanga pulasitiki yokhala ndipamwamba kwambiri. Kuphatikiza apo, makopewa amagwiritsidwa ntchito powonera malingaliro kapena kukonza zolakwika zamapangidwe.
Ntchito Zamakampani a Plastic CNC Machining
Makina apulasitiki a CNC amagwiritsidwa ntchito kwambiri chifukwa cha maubwino monga kulondola, kulondola, komanso kulolerana kolimba. Zomwe zimagwiritsidwa ntchito m'mafakitale zikuphatikizapo:
Makampani azachipatala
Makina apulasitiki a CNC akugwiritsidwanso ntchito popanga zida zamakina azachipatala monga miyendo yopangira komanso mitima yopangira. Kulondola kwake komanso kubwerezabwereza kumalola kuti ikwaniritse miyezo yolimba yachitetezo yomwe makampani amafunikira. Kuphatikiza apo, pali zinthu zambiri zomwe mungasankhe, ndipo zimapanga mawonekedwe ovuta.
Zida Zagalimoto
Onse opanga magalimoto ndi mainjiniya amagwiritsa ntchito makina a Plastic CNC kupanga zida zamagalimoto zenizeni ndi ma prototypes. Pulasitiki imagwiritsidwa ntchito kwambiri pamakampani popanga zida zapulasitiki za cnc monga ma dashboards chifukwa chopepuka, zomwe zimachepetsa kugwiritsa ntchito mafuta. Kuphatikiza apo, pulasitiki imalimbana ndi dzimbiri komanso kuvala, zomwe zida zambiri zamagalimoto zimakumana nazo. Kupatula apo, pulasitiki imatha kuumbika m'mawonekedwe ovuta mosavuta.
Zida Zamlengalenga
Kupanga gawo lazamlengalenga kumafuna njira yopangira yomwe imakhala yolondola kwambiri komanso kulolerana kolimba. Zotsatira zake, makampaniwa amasankha makina a CNC pakupanga, kuyesa, ndi kumanga magawo osiyanasiyana amlengalenga. Zida zamapulasitiki zimagwira ntchito chifukwa choyenerera mawonekedwe ovuta, mphamvu, zopepuka komanso zamankhwala apamwamba, komanso kukana kutentha.
Makampani Amagetsi
Makampani opanga zamagetsi amakondanso makina apulasitiki a CNC chifukwa chakulondola kwake komanso kubwerezabwereza. Pakadali pano, njirayi imagwiritsidwa ntchito popanga zida zamagetsi zamapulasitiki opangidwa ndi CNC monga mawaya, ma keypads, ndi zowonera za LCD.
Nthawi Yosankha Pulasitiki CNC Machining
Kusankha kuchokera kuzinthu zambiri zopangira pulasitiki zomwe takambiranazi zingakhale zovuta. Zotsatira zake, pansipa pali malingaliro angapo omwe angakuthandizeni kusankha ngati makina apulasitiki a CNC ndiye njira yabwino kwambiri ya polojekiti yanu:
Ngati Pulasitiki Prototype Design yokhala ndi Tight Tolerance
CNC pulasitiki Machining ndiye njira yabwino kwambiri yopangira magawo okhala ndi mapangidwe omwe amafunikira kulolerana kolimba. A ochiritsira CNC mphero makina akhoza kukwaniritsa kulolerana zolimba pafupifupi 4 μm.
Ngati Pulasitiki Prototype Ikufuna Upamwamba Wapamwamba Malizani
Makina a CNC amapereka mawonekedwe apamwamba apamwamba kuti akhale oyenera ngati polojekiti yanu sikufunika njira yowonjezera yomaliza. Izi ndizosiyana ndi kusindikiza kwa 3D, komwe kumasiya zizindikiro panthawi yosindikiza.
Ngati Pulasitiki Prototype Ikufuna Zida Zapadera
Makina apulasitiki a CNC angagwiritsidwe ntchito kupanga zigawo kuchokera kuzinthu zambiri zapulasitiki, kuphatikizapo zomwe zili ndi katundu wapadera monga kukana kutentha kwambiri, mphamvu zambiri, kapena kukana kwa mankhwala. Izi zimapangitsa kukhala chisankho chabwino popanga ma prototype okhala ndi zofunikira zapadera.
Ngati Zogulitsa Zanu Zili Pamayeso
Makina a CNC amadalira mitundu ya 3D, yomwe ndi yosavuta kusintha. Popeza gawo loyeserera limafuna kusinthidwa kosalekeza, makina a CNC amalola opanga ndi opanga kupanga ma prototypes apulasitiki ogwira ntchito kuti ayese ndikuwongolera zolakwika.
· Ngati Mukufuna Njira Yachuma
Monga njira zina zopangira, makina apulasitiki a CNC ndi oyenera kupanga magawo otsika mtengo. Pulasitiki ndi yotsika mtengo kusiyana ndi zitsulo ndi zipangizo zina, monga composites. Kuphatikiza apo, kuwongolera manambala apakompyuta ndikolondola, ndipo njirayo ndiyoyenera kupanga zovuta.
Mapeto
Makina apulasitiki a CNC ndi njira yovomerezeka kwambiri m'mafakitale chifukwa cha kulondola kwake, kuthamanga, komanso kukwanira kupanga magawo moleza mtima. Nkhaniyi ikukamba za zosiyanasiyana CNC Machining zipangizo n'zogwirizana ndi ndondomeko, njira zilipo, ndi zinthu zina zimene zingathandize polojekiti yanu.
Kusankha njira yoyenera yopangira makina kungakhale kovuta kwambiri, zomwe zimakupangitsani kuti mutuluke kwa wothandizira pulasitiki wa CNC. Ku GuanSheng timapereka makina opanga makina a pulasitiki a CNC ndipo angakuthandizeni kupanga magawo osiyanasiyana a prototyping kapena kugwiritsa ntchito nthawi yeniyeni kutengera zomwe mukufuna.
Tili ndi zida zingapo zapulasitiki zoyenera makina a CNC okhala ndi njira yokhazikika komanso yosankhira. Kuphatikiza apo, gulu lathu la uinjiniya litha kupereka upangiri waukadaulo wosankha zinthu ndi malingaliro apangidwe. Kwezani mapangidwe anu lero ndikupeza ma quotes pompopompo ndikuwunika kwaulere kwa DfM pamtengo wopikisana.
