Ukugqiba linyathelo lokugqibela kwi-CNC machining kwaye kungasetyenziselwa ukuphucula umgangatho wemveliso. Ukugqiba kunokususa iziphene zembonakalo, kuphucule imiphumo yokubonakala kwemveliso, kwaye kuphucule amandla oomatshini okanye ukusebenza kombane.
Xa ujongene neendlela ezahlukeneyo zonyango lomphezulu, abaphathi beemveliso kunye nabayili bakhetha njani isisombululo esifanelekileyo? Ungakhathazeki, olu hlobo lonyango luqhelekileyo luneengenelo zalo. Ukuba nje uyaziqonda iimpawu zendlela nganye, ungongeza amanqaku kwimveliso.

Imeko yokucubungula
Umphezulu weendawo eziveliswa yi-CNC machining ubizwa ngokuba "ngumphezulu ocutshungulweyo". Umphezulu urhabaxa kodwa unomlinganiselo oqinileyo wokunyamezelana, okwaneleyo kwezinye izicelo zobunjineli. Ubukhulu obuqhelekileyo bumalunga ne-3.2μm, kwaye akukho mfuneko yokucubungula okulandelayo, ngoko ke ukusebenza kakuhle kwemveliso kuphezulu.
Kwizicelo apho ukuchaneka kobukhulu kubaluleke ngaphezu kwembonakalo, lo mphezulu womatshini wanele. Nangona kunjalo, ngenxa yokuba lukhuni kwaye akukho ngubo yokukhusela, umphezulu awunazo izixhobo zokukhusela ezisemgangathweni kwaye unokuba nemikrwelo kwaye uguge. Ngokubanzi, umlinganiselo wexabiso/wokusebenza wanele kwezinye iimeko, ngelixa unyango olongezelelweyo lomphezulu lunokufuneka apho ukhuseleko luphezulu.
I-Anodizing yinkqubo ye-electrochemical enokwenza ifilimu ye-oxide etyebileyo nexineneyo kumphezulu weendawo ezenziwe ngomatshini ze-CNC, ngaloo ndlela iphucula ukusebenza kokukhusela.
Le nkqubo ingasetyenziswa kuphela kwi-aluminium okanye i-titanium alloys kuba ziqhuba kakuhle. Ngexesha lenkqubo, i-alloy ifakwa kwi-electrolyte tank ene-asidi ukuze isebenze njenge-anode, kwaye umbane usetyenziselwa ukudibanisa ii-ion ze-oxygen kwi-asidi kunye nee-athomu ze-alloy ezikumphezulu ukwenza ifilimu ye-oxide.
Kukho iintlobo ezimbini eziphambili ze-anodization. Ziyinkqubo efanayo iyonke, kodwa zifuna ukuba iindawo zifakwe kwizisombululo ze-sulfuric acid zamanqanaba ahlukeneyo. Uhlobo lwesibini lubizwa ngokuba yi-"decorative anodization", oluvelisa uqweqwe olucacileyo okanye olunemibala olunobukhulu obuyi-4-25 μm; uhlobo lwesithathu lubizwa ngokuba yi-"hard coat anodization", olunobukhulu be-coating obuyi-125 μm kwaye alugugi.
Lilonke, ukugqitywa kwe-anodized kuhlala ixesha elide kwaye kuzinzile ngokwemilinganiselo, nto leyo eyenza ukuba kube yeyona ifanelekileyo kwimingxuma yangaphakathi kunye neendawo ezincinci ezifuna ukusebenza okuphezulu. Yenye yezona ndlela zibalaseleyo phakathi kokugqitywa kwe-CNC machined, kodwa ixabiso liphezulu kakhulu.
Ukwambathisa ngomgubo
Ukwambathisa ngomgubo kufana nepeyinti yokutshiza. Okokuqala, unyango lwe-phosphating okanye i-chromate anti-corrosion lusetyenziswa kumphezulu wenxalenye, emva koko iindawo zitshizwa ngomgubo owomileyo ngesibhamu se-electrostatic kwaye zinyangwe kwi-oven engaphezulu kwama-200°C. Ukufakwa kwe-multi-layer stacking kunokufikelela kubukhulu be-72μm.
Olu nyango ngokwalo lunokwenza ifilimu ekhuselayo kwiindawo ze-CNC, eqinileyo, enganyangekiyo kwaye intle. Ingadityaniswa nesanti-blasting ukuphucula ukusebenza kokulwa nokugqwala kunye nokufana komphezulu weendawo.
Ngokungafaniyo ne-anodizing, i-powder coating iyahambelana nazo zonke iintsimbi, inokuqina okuqinileyo, kunye nokumelana okuphezulu kwempembelelo, okwenza ifaneleke kwiintlobo ngeentlobo zezicelo ezisebenzayo, ngakumbi ukusetyenziswa kwemikhosi.
Kodwa i-powder coating ayinalawulo luhle kwaye ayifanelekanga kwiindawo ezincinci okanye kwiindawo zangaphakathi. Ngaphezu koko, iindleko eziphezulu zinokunciphisa ukusetyenziswa kwayo kwimveliso enkulu.
Ukuqhumisa iintsimbi kusetyenziswa ukongeza umphezulu ongathi matte okanye wesatin kwinxalenye eyenziwe ngomatshini ye-CNC. Ngexesha lale nkqubo, umoya oxinzelelweyo utyhala izigidi zeentsimbi zeglasi kwinxalenye, ususa ngempumelelo iimpawu zezixhobo kunye nokungafezeki ukuze kudalwe ubume obufanayo begrain. Ngokungafaniyo nezinye izinto ezigqityiweyo ezifana nokufunxa i-anodizing kunye nokufumisa i-powder, ukuqhumisa iintsimbi akuyitshintshi inxalenye ngokwekhemikhali okanye ngoomatshini - kutshintsha inkangeleko ngokubonakalayo. Ngokungafaniyo nokufumisa i-powder okongeza izinto, ukuqhumisa iintsimbi kuyanciphisa njengoko kususa inani elincinci lezinto. Oku kubalulekile ukuba inxalenye yakho inokunyamezelana okuqinileyo.
Ukuqhumisa iintsimbi yenye yezona zinto zifikelelekayo zokugqiba umphezulu, kodwa kufuna ukusetyenziswa ngesandla. Abo bacinga ukuba kufuneka balungiselele umqhubi oqeqeshwe ngokusesikweni kuba umgangatho wokugqiba uxhomekeke kakhulu kwisakhono. Uhlobo lweentsimbi kunye nobukhulu obusetyenzisiweyo nazo zichaphazela iziphumo. Nangona kuyinkqubo yesandla, ukuqhumisa iintsimbi kuhlala kuyindlela eguquguqukayo nengabizi kakhulu yokugqiba iindawo ze-CNC ngendlela enokunyamezeleka.
Iingcebiso malunga nokugqiba iindawo ezenziwe ngomatshini ze-CNC
Ngamafutshane, kwiindawo ezingadingi mfanekiso ugqibeleleyo kodwa kufuneka zigcine ubukhulu bazo bokuqala, unyango lomphezulu emva kwenkqubo efana ne-anodizing okanye i-powder coating lunokuba lukhetho olusebenzayo. I-anodizing iphucula amandla okukhusela eenxalenye ze-aluminium okanye ze-titanium. Xa inxalenye ingenakwenziwa i-anodize kodwa ifuna amandla kunye nokumelana nempembelelo, i-powder coating inika enye indlela. Ekugqibeleni, ukuba ukusebenza kakuhle kweendleko kubaluleke ngaphezu kokunyamezelana—kwaye inxalenye ayifuni umphezulu ogudileyo—ukuqhushumba kwesanti kunokuba yindlela engcono.
Iinjineli, abayili, kunye nabaphathi beemveliso bacetyiswa ukuba babonisane neengcali zokwenza izinto ukuqinisekisa ukuba benza ukhetho olufanelekileyo kwiprojekthi yabo elandelayo. Iingcali zikaKachi zinolwazi kuzo zonke iinkalo zenkqubo yokwenza izinto, ukusuka kuyilo lwemveliso kunye neprototyping ukuya kwimveliso enkulu. Iqela lethu linokukunceda ukhethe unyango olungcono kakhulu lwezinto zakho ezenziwe ngomatshini we-CNC kwaye uqinisekise ukuba uya kwimarike ngemveliso eqinileyo neyomgangatho ophezulu.
