Irangiza kuri CNC ikora ibyuma na alloy prototype ibice
Mu myaka 40 ishize, abakanishi ba Prototype Projects basabwe kubyaza umusaruro ibice byinshi byibyuma hamwe nuruvange rwo gukoreshwa mubikorwa byinshi ndetse ninganda.Ibice bya CNC byakozwe mubisanzwe birasubirwamo, bigasukurwa kandi bikangirika ariko, nyuma yibyo, guhitamo ibyongeweho biragutse cyane.
Noneho, abakiriya bacu ibyuma bizwi cyane ni aluminiyumu, ibyuma bitagira umwanda.
Biracyakunzwe ariko byerekanwe gake cyane ni umuringa, umuringa, fosifore y'umuringa, ibyuma byoroheje, ibyuma.Rimwe na rimwe, abakiriya basaba kandi CNC gutunganya mubindi byuma byinshi hamwe na alloys.
Ibyuma n'amavuta arashobora kurangizwa muburyo bwinshi butandukanye.Kurugero, aluminiyumu irashobora kuba isobanutse neza, ikoti ikarishye, cyangwa umukara cyangwa ibara ryera, nubwo 6082 ya aluminiyumu yemera anodisingi neza ugereranije nandi manota.Mu buryo nk'ubwo, isahani y'ibikoresho 5083 dukoresha irashobora gutanga ibimenyetso bitondetse.Guhitamo biterwa nibisabwa nukuzamura ubwiza cyangwa imikorere (cyane cyane kurwanya ruswa cyangwa kwambara).
Ibyuma bidafite ingese birashobora kwihanganira kwangirika ariko rimwe na rimwe abakiriya bagaragaza ibyarangiye.Electropolishing, kurugero, itanga ubuziranenge bwo kurangiza kimwe no gukuraho burrs nimpande zikarishye mubice bikomeye.Ku rundi ruhande, niba ubukana bwo hejuru, kwambara birwanya cyangwa umunaniro bigomba kunozwa, ibyuma 304 na 316 ibyuma bitagira umwanda birashobora kuba nitride cyangwa nitrocarburised.
Ibyuma byoroheje byunguka wenda guhitamo kwagutse kurangiza.Amahitamo arimo gushushanya neza, gushushanya amashanyarazi, gusiga ifu, amashanyarazi, kwirabura imiti, guturika amasaro, amashanyarazi, gukomera, titanium nitriding (TiN) gutwikira, nitriding na nitrocarburising.
Ubusanzwe umuringa n'umuringa bisobanurwa kubice bikora, ntakindi gisabwa nyuma yo gukora.Nibiba ngombwa, ariko, ibice birashobora guhanagurwa nintoki, amashanyarazi, amashanyarazi, imyuka yaturitse, lacage cyangwa ikavurwa hakoreshejwe imiti yirabura.
Kurangiza byavuzwe haruguru ntabwo aribyo byonyine biboneka kubicyuma na alloys.Buri gihe twishimiye kuganira kurangiza nabakiriya kandi twihatira gufasha aho dushoboye hose.
Irangiza kuri CNC yatunganijwe ibice bya prototype
Kimwe nicyuma nibice bivanze, ibice byose bya pulasitike twe imashini ya CNC byangiritse, bisukurwa kandi birangirika ariko, nyuma yibyo, amahitamo yo kurangiza akunda kuba atandukanye.
Nkuko abakiriya benshi basaba CNC yakozwe na prototype ibice bya plastike mubice bya acetal (umukara cyangwa karemano) cyangwa acrylic, turabifata mububiko bwa serivisi yacu yo gutunganya Express CNC.Acetal ntabwo yemera byoroshye kurangiza, bityo ibice mubisanzwe bitangwa 'nkuko byakozwe'.Acrylic, isobanutse, akenshi isukuye kugirango itange ikirahure.Ibi birashobora gukorwa nintoki hamwe n amanota meza yikurikiranya ya abrasive, cyangwa hamwe na flame polishing.Iyo bikenewe, acrylic irashobora gusiga irangi irangi rya acrylic cyangwa vacuum metallised kugirango igere hejuru cyane.
Kurenga acetal na acrylic, twe imashini ya prototype ya CNC duhereye kubintu byinshi bya plastiki yubuhanga.
Bimwe muribi byoroshye kurangiza kurenza ibindi, burigihe rero urahawe ikaze kuganira kubikoresho no kurangiza natwe mbere yo gusaba amagambo.Ukurikije plastike, turashobora kumucanga, ibice byingenzi no gusiga irangi, kubisiga (intoki cyangwa kumuriro), isahani idafite amashanyarazi cyangwa icyuma cya vacuum.Kuri plastiki zimwe zifite ingufu nke zo hejuru, gutegura ubuhanga bwihariye hamwe na primer cyangwa plasma yo kuvura birakenewe.
Igenzura rinini rya CNC ryakozwe na prototype ibice
Impamvu imwe ituma abakiriya bahitamo kugira prototype ibice CNC ikozwe aho kuba icapiro rya 3D ni ukuri kwukuri.Kwihanganira twavuze kubice bya CNC byakozwe ni ± 0.1mm, nubwo ibipimo bisanzwe bifatirwa kwihanganira cyane, bitewe nibikoresho na geometrie.Buri gihe tugenzura ibipimo byerekana nyuma yo gutunganya, kandi abakiriya nabo barashobora gusaba ibintu byihariye bigomba kugenzurwa.
Akenshi ibipimo birashobora gufatwa hamwe nabahamagaye cyangwa micrometero ariko imashini yacu yo gupima (CMM) nibyiza kubigenzurwa neza.Ibi bifata igihe kandi ntibishoboka hamwe na serivise yacu ya Express CNC ariko birihuta kuruta kohereza ibice kubandi bantu kugirango bagenzure CMM.Ibidasanzwe gusa ni mugihe hakenewe gahunda yuzuye yo kugenzura CMM yuzuye, yuzuye, cyangwa igice cyibice cyarakozwe kandi birasabwa kugenzurwa 100%.
Amahitamo yinteko ya CNC yatunganijwe ibice bya prototype
'Inteko' hano isobanura ikintu cyose uhereye kwinjiza Helicoils mubice bya aluminiyumu ya aluminiyumu cyangwa gushyiramo imigozi mu bice bya pulasitike, binyuze mu gushiraho ibyuma no gushyira ibirango byanditse.Akenshi turasabwa guhuza ibice byakozwe na CNC nibindi bice bya prototype, byaba byarakozwe na CNC, byacapwe 3D cyangwa vacuum.
Mubyukuri, tuzakora hafi urwego urwo arirwo rwose rwo guteranya porotipiki ikora cyangwa moderi igaragara, dushyiramo ibice bya prototype cyangwa ibisanzwe bitari muri tekinike nkuko bikenewe.Ubundi buryo ni ukurenga ibice bya CNC byakozwe na polyurethane ukoresheje vacuum.
