Kugira ngo ukureho imyitozo ya CNC nta byangiritse, menya neza ko ubujyakuzimu butarenze inshuro eshatu cyangwa enye. diameter. Kandi, gabanya igipimo cyibiryo mugihe imyitozo imaze gusohoka mubintu.
Ubundi buryo bwo gukora plastike
Usibye gutunganya ibice bya plastike ya CNC, ubundi buryo bwihuse bwa prototyping burashobora kuba ubundi buryo. Ibisanzwe birimo:
Gutera inshinge
Nibikorwa bizwi cyane-byo gukora cyane hamwe nibikorwa bya plastiki. Gutera inshinge bikubiyemo gukora ibishushanyo biva muri aluminium cyangwa ibyuma bitewe nibintu nko kuramba. Nyuma, plastiki yashongeshejwe yinjizwa mu cyuho kibumba, ikonje, kandi ikora ishusho yifuza.
Gutera inshinge za plastike birakwiriye haba prototyping no gukora ibice bifatika. Usibye ibyo, nuburyo buhendutse bukwiranye nibice bifite ibishushanyo byoroshye kandi byoroshye. Ikigeretse kuri ibyo, ibice byatewe inshinge ntibisaba akazi kiyongereye cyangwa kuvura hejuru.
Icapiro rya 3D
Icapiro rya 3D nuburyo busanzwe bwa prototyping bukoreshwa mubucuruzi buciriritse. Uburyo bwo gukora inyongeramusaruro nigikoresho cyihuta cya prototyping igizwe nikoranabuhanga nka Stereolithography (SLA), Fused Deposition Modeling (FDM), na Selective Laser Sintering (SLS) ikoreshwa mugukora kuri thermoplastique nka nylon, PLA, ABS, na ULTEM.
Buri tekinoroji ikubiyemo gukora 3D ya moderi yububiko no kubaka ibice byifuzwa kumurongo. Ibi ni nka plastike ya CNC itunganya, nubwo itwara ibintu bike, bitandukanye nibyanyuma. Byongeye kandi, bivanaho gukenera ibikoresho kandi birakwiriye cyane gukora ibice bifite ibishushanyo mbonera.
Gutera Vacuum
Gutera Vacuum cyangwa polyurethane / urethane guteramo birimo silikoni ya silicon hamwe na resin kugirango ikore kopi yicyitegererezo. Inzira yihuta ya prototyping irakwiriye gukora plastike ifite ireme ryiza. Byongeye kandi, kopi zirakoreshwa mugutekereza ibitekerezo cyangwa gukemura ibibazo byubusa.
Inganda zikoreshwa mubikorwa bya plastiki CNC
Gukora plastike ya CNC birakoreshwa cyane kubera inyungu nkukuri, neza, no kwihanganira cyane. Inganda zisanzwe zikoreshwa mubikorwa zirimo:
Inganda zubuvuzi
CNC itunganya plastike kuri ubu irakoreshwa mugukora ibice bikoreshwa mubuvuzi nkibihimba bya prostate hamwe numutima wubukorikori. Urwego rwo hejuru rwukuri kandi rusubirwamo rutuma rwuzuza amahame akomeye yumutekano asabwa ninganda. Ikigeretse kuri ibyo, hari ibintu byinshi bitaboneka, kandi bitanga imiterere igoye.
Ibinyabiziga
Abashushanya imodoka naba injeniyeri bombi bakoresha imashini ya Plastike CNC kugirango bakore ibinyabiziga nyabyo-na prototypes. Plastike irakoreshwa cyane munganda mugukora ibice bya plastike cnc byabigenewe nkibibaho bitewe nuburemere bwabyo, bigabanya gukoresha lisansi. Byongeye kandi, plastike irwanya kwangirika no kwambara, ibyinshi mubinyabiziga bifite uburambe. Usibye ibyo, plastiki ibumbabumbwa muburyo bworoshye.
Ibice byo mu kirere
Gukora igice cyindege bisaba uburyo bwo gukora bufite ubusobanuro buhanitse kandi bwihanganirana. Nkigisubizo, inganda zihitamo gutunganya CNC mugushushanya, kugerageza, no kubaka ibice bitandukanye byakorewe mu kirere. Ibikoresho bya plastiki birakoreshwa bitewe nuburyo bukwiranye nuburyo bugoye, imbaraga, uburemere bworoshye n’imiti myinshi, hamwe n’ubushyuhe.
Inganda za elegitoroniki
Inganda za elegitoroniki nazo zishyigikira imashini ya plastike ya CNC kubera ubwinshi bwayo kandi igasubirwamo. Kugeza ubu, inzira irakoreshwa mugukora ibice bya elegitoroniki bya CNC byakozwe na CNC nk'uruzitiro rw'insinga, kode y'ibikoresho, na ecran ya LCD.
Igihe cyo Guhitamo imashini ya plastike CNC
Guhitamo mubikorwa byinshi byo gukora plastike byavuzwe haruguru birashobora kugorana. Nkigisubizo, hepfo haribintu bike bishobora kugufasha guhitamo niba gutunganya plastike CNC aribwo buryo bwiza kumushinga wawe:
Niba igishushanyo mbonera cya plastiki hamwe no kwihanganirana
Gukora plastike ya CNC nuburyo bwiza bwo gukora ibice bifite ibishushanyo bisaba kwihanganira cyane. Imashini isanzwe ya CNC yo gusya irashobora kugera kwihanganira hafi ya 4 mm.
Niba Plastike Prototype isaba uburinganire bwuzuye Kurangiza
Imashini ya CNC itanga ubuziranenge bwo hejuru irangiza ikabikora neza niba umushinga wawe udakeneye inzira yinyongera yo kurangiza. Ibi bitandukanye no gucapa 3D, isiga ibimenyetso byerekana mugihe cyo gucapa.
Niba prototype ya plastike isaba ibikoresho byihariye
Imashini ya plastike CNC irashobora gukoreshwa mugukora ibice biva mubikoresho byinshi bya plastiki, harimo nibifite ibintu byihariye nko kurwanya ubushyuhe bwinshi, imbaraga nyinshi, cyangwa imiti myinshi irwanya imiti. Ibi bituma uhitamo neza gukora prototypes hamwe nibisabwa byihariye.
Niba ibicuruzwa byawe biri mukigeragezo
Imashini ya CNC ishingiye kuri moderi ya 3D, byoroshye guhinduka. Kubera ko icyiciro cyo kwipimisha gisaba guhora gihinduka, imashini ya CNC yemerera abayikora nababikora gukora prototypes ikora kugirango igerageze kandi ikemure amakosa yakozwe.
· Niba ukeneye amahitamo yubukungu
Kimwe nubundi buryo bwo gukora, gutunganya CNC ya plastike birakwiriye gukora ibice neza. Plastike ihenze cyane kuruta ibyuma nibindi bikoresho, nkibigize. Byongeye kandi, kugenzura imibare ya mudasobwa birasobanutse neza, kandi inzira irakwiriye kubishushanyo mbonera.
Umwanzuro
Gukora plastike ya CNC ni inzira yemewe mu nganda bitewe nukuri, umuvuduko, hamwe nuburyo bukwiye bwo gukora ibice byihanganirana. Iyi ngingo ivuga kubyerekeye ibikoresho bitandukanye byo gutunganya CNC bihuye nibikorwa, tekinoroji ihari, nibindi bintu bishobora gufasha umushinga wawe.
Guhitamo uburyo bukwiye bwo gutunganya ibintu birashobora kugorana cyane, bigusaba kohereza hanze ya serivise ya CNC itanga plastike. Muri GuanSheng dutanga serivisi za plastike CNC yihariye kandi irashobora kugufasha gukora ibice bitandukanye bya prototyping cyangwa gukoresha igihe nyacyo ukurikije ibyo usabwa.
Dufite ibikoresho byinshi bya pulasitiki bikwiranye no gutunganya CNC hamwe nuburyo bukomeye bwo guhitamo. Byongeye kandi, itsinda ryacu ryubwubatsi rirashobora gutanga inama zo guhitamo ibikoresho byumwuga hamwe nigitekerezo cyo gushushanya. Kuramo igishushanyo cyawe uyumunsi hanyuma ubone ibisobanuro byihuse hamwe na DfM yubusa kubiciro byapiganwa.
