CNC kugaya uye kutendeutsa kunochinja-chinja, inodhura-inoshanda uye yakarurama, zvakadaro mikana yeCNC michini yezvikamu inowedzera zvakanyanya kana kumwe kupedzisa kuchitariswa.Ndezvipi zvingasarudzwa?Kunyange zvazvo izvozvo zvichiita semubvunzo wakapfava, mhinduro yacho yakaoma kunzwisisa nokuti pane zvinhu zvakawanda zvokufunga nezvazvo.
Kutanga, kuguma ndekwechii?Iko kuvandudza aesthetics kana kuita?Kana iyo yekupedzisira, ndeapi maitiro ekuita anoda kuvandudzwa?Corrosion kuramba, kuoma kwepasi, kupfeka kuramba kana EMI/RFI kudzivirira?Iyi ingori mimwe yemibvunzo ichapindurwa saka, tichifunga kuti mugadziri anoziva zvinangwa, ngatitarisei pane dzakasiyana sarudzo.
Inopedzisa CNC yakagadzirwa nesimbi uye alloy prototype zvikamu
Kwemakore makumi mana apfuura, maPrototype Projects 'machinist akakumbirwa kuti abudise zvikamu kubva kune yakakura yakawanda simbi uye alloys ekushandisa mune yakatowanda maindasitiri.Zvikamu zvemuchina zveCNC zvinogara zvichibviswa, kucheneswa uye kucheneswa asi, mushure meizvozvo, sarudzo yekuwedzera yekupedzisa yakafara kwazvo.
Zvino, vatengi vedu 'anonyanya kufarirwa simbi ialuminium alloy, Stainless simbi.
Ichiri kufarirwa asi yakataurwa zvishoma kazhinji imhangura, ndarira, phosphor bronze, nyoro simbi, mudziyo simbi.Nguva nenguva, vatengi vanokumbirawo CNC machining mune akawanda mamwe simbi uye alloys.
Metals uye alloys zvinogona kupedzwa nenzira dzakawanda dzakasiyana.Semuenzaniso, aruminiyamu inogona kuve yakajeka anodised, hardcoat anodised, kana dema kana ruvara anodised, kunyangwe 6082 aruminiyamu alloy inogamuchira anodising zvishoma pane mamwe mamakisi.Saizvozvowo, ndiro ye5083 yatinoshandisa inokwanisa kuburitsa mavara ane makwapa.Sarudzo inoenderana nekuti chinodiwa ndechekusimudzira aesthetics kana kuita (kunyanya corrosion resistance kana kupfeka kuramba).
Simbi isina simbi inoshingirira mukuora asi dzimwe nguva vatengi vanotsanangura mamwe mapeji.Electropolishing, semuenzaniso, inogadzira kupedzisa kwemhando yepamusoro pamwe nekubvisa mabhura uye mipendero yakapinza kubva muzvikamu zvakaomarara.Kune rimwe divi, kana kuomarara kwepamusoro, kupfeka kuramba kana kuneta kuita kuchida kuvandudzwa, ese 304 uye 316 simbi isina tsvina inogona kuve nitrided kana nitrocarburised.
Simbi yakapfava inobatsira kubva pamwe sarudzo yakafararira yekupedzisa.Sarudzo dzinosanganisira pendi yakanyorova, pendi ye electrophoretic, poda coating, electroplating, kusviba kwemakemikari, kuputika bead, electropolishing, kuomesa nyaya, titanium nitriding (TiN) coating, nitriding uye nitrocarburising.
Mhangura nendarira zvinowanzotsanangurwa kune zvikamu zvinoshanda, pasina kumwe kupedzisa kunodiwa mushure mekugadzira.Kana zvichidikanwa, zvisinei, zvikamu zvinogona kukwenenzverwa nemaoko, electropolished, electroplated, vapor blasted, lacquered kana kurapwa nemakemikari blacking.
Mapedzisiro ataurwa pamusoro apa haasi iwo ega anowanikwa esimbi uye alloys.Isu tinogara tichifara kukurukura zvekupedzisa nevatengi uye tinoedza kubatsira chero kwatinogona.
Inopedzisa CNC yakagadzirwa epurasitiki prototype zvikamu
Sezvakaita simbi uye alloy zvikamu, ese epurasitiki zvikamu isu CNC muchina zvakabviswa, kucheneswa uye kucheneswa asi, mushure meizvozvo, sarudzo dzekupedzisa dzinowanzove dzakasiyana.
Sezvo ruzhinji rwevatengi vanokumbira CNC yakashongedzwa prototype epurasitiki zvikamu mune angave acetal (dema kana zvisikwa) kana acrylic, isu tinobata izvi mustock kune yedu Express CNC machining sevhisi.Acetal haigamuchire magumo ekuwedzera, saka zvikamu zvinowanzo kupihwa 'semuchina'.Acrylic, kuva yakajeka, inowanzoputirwa kuti ipe girazi-sekuonekwa.Izvi zvinogona kuitwa nemaoko nemakiredhi akateedzana eabrasive, kana nekupenya kwemoto.Kana zvichidikanwa, acrylic inogona kupendwa ne acrylic pendi kana vacuum metallised kuti iwane yakanyanya kupenya pamusoro.
Kupfuura acetal uye acrylic, isu CNC muchina prototype zvikamu kubva kune yakakura huwandu hweinjiniya mapurasitiki.
Zvimwe zveizvi zviri nyore kupedza kupfuura zvimwe, saka unogamuchirwa nguva dzose kukurukura zvekushandisa uye kupedza nesu usati wakumbira mutengo.Zvichienderana nepurasitiki, tinogona kuita jecha, prime uye pendi zvikamu, kupukuta (nemaoko kana nemurazvo), electroless ndiro kana vacuum metallise.Kune mamwe mapurasitiki ane yakaderera pamusoro pesimba, nyanzvi kugadzirira pamusoro neprimer kana plasma kurapwa kunodiwa.
Dimensional yekuongorora yeCNC yakagadzirwa prototype zvikamu
Chimwe chikonzero nei vatengi vachisarudza kuve neprototype zvikamu CNC muchina pane 3D yakadhindwa ndiko kurongeka kwepamusoro.Kushivirira kwedu kwakatarwa kweCNC michina yezvikamu ndeye ± 0.1mm, asi zviyero zvinowanzobatwa kune zvakanyanya kushivirira, zvichienderana nechinhu uye geometry.Isu tinogara tichitarisa zviyero zvemumiriri mushure mekugadzira, uye vatengi vanogona zvakare kukumbira kuti chaiwo maficha atariswe zvakare.
Kazhinji zviyero zvinogona kutorwa nemaoko anosheedzera callipers kana mamicrometer asi yedu co-ordinator yekuyeresa muchina (CMM) yakanakira kunyatsoongorora.Izvi zvinotora nguva uye hazviwanikwe neyedu Express CNC sevhisi asi inokurumidza kupfuura kutumira zvikamu kune wechitatu-bato kuti CMM iongororwe.Izvo chete zvinosarudzika ndezvekuti panodikanwa, yakazara-yakarongedzwa-yakazara CMM yekuongorora routine, kana batch rezvikamu rakagadzirwa uye 100 muzana yekuongorora inodiwa.
Sarudzo dzeGungano dzeCNC dzakagadzirwa prototype zvikamu
'Assembly' pano inoreva chero chinhu kubva pakuisa maHelicoils muaruminiyamu alloy parts kana kuti akaiswa threaded muzvikamu zvepurasitiki, kusvika pakuisa mabearings nekuisa mavara akadhindwa.Kazhinji tinokumbirwa kusanganisa zvikamu zveCNC zvemuchina nezvimwe zvikamu zveprototype, zvingave zvakagadzirwa neCNC, 3D yakadhindwa kana vacuum cast.
Muchokwadi, isu tichaita ingangoita chero nhanho yekusangana kweanoshanda prototypes kana mamodheru anooneka, tichibatanidza prototype zvikamu kana zvakajairwa off-the-sherufu chikamu sezvinodiwa.Imwe sarudzo ndeyekuwedzeredza CNC machini zvikamu ne polyurethane nekukanda vacuum.
