Uma ubheka izingxenye ze-aluminium ezenziwe ngensimbiimoto or ezokuxhumanaizimboni, ufuna isiphetho esibushelelezi, esingenasici. Imishini ye-CNC ikunikeza lolo mngcele. Kuthatha izindawo ezimahhadlahhadla, ezifana nokulingisa futhi kuzenze zibeshelele futhi ziqonde. Bheka nje umehluko:
| Inqubo | I-Surface Finish Ejwayelekile (Ra) |
|---|---|
| I-Die Casting | 125-300 amasentimitha |
| CNC Machining | 16-125 amasentimitha |
| I-Sand Casting | 250-900 amasentimitha |
Ungabona ukuthi ukwenza imishini ye-CNC kukusiza kanjani ukuthi ufinyelele isiphetho esihle kakhulu, wenze zonke izingxenye zibukeke futhi zenze kangcono.
Okuthathwayo Okubalulekile
- CNC machining kakhuluithuthukisa isiphetho sangaphezuluwezingxenye ze-aluminium enziwe, ukufeza ukuqeda okushelelayo phakathi kuka-16 no-125 microinches Ra.
- Ukusebenzisa i-CNC milling kanye nezinqubo zokuguqulakuthuthukisa ukunembakanye nokuvumelana kwezingxenye, okuqinisekisa ukubekezelelana okuqinile nokusebenza okungcono.
- Amasu okuqedela athuthukile njengokupholisha kanye ne-anodizing awathuthukisi nje kuphela ukubukeka kodwa futhi andisa ukuqina nokumelana nokugqwala.
Imikhawulo Yokuqeda Ubuso Ekusakazeni Kwe-Cast Aluminium
Ukungapheleli Okujwayelekile ku-Cast Aluminium
Uma usebenza nge-aluminium ekhonjiwe, ungase ubone amaphutha endaweni. Lokhu kungapheleli kungathinta indlela izingxenye zakho ezibukeka futhi zisebenza ngayo. Nazi izinkinga ezimbalwa ongazibona:
- Ukuqedwa kwendawo kudlala indima enkuluukuthi ingxenye yakho ihlala isikhathi esingakanani.
- Uma isiphetho singalungile, ukumelana nokugqwala kuyehla.
- Kwesinye isikhathi, ingxenye ayibukeki kahle ngendlela ofisa ngayo.
Ungase futhi ubone izinhlobo ezimbili ze-porosity. Ukuqina kwegesi kwenzeka lapho umoya noma i-hydrogen ivaleleka ensimbi, ishiya izimbobo ezincane, eziyindilinga. I-shrinkage porosity ibonakala njengemigodi emikhulu, emise okwenqaba lapho insimbi iphola futhi incipha.
Izinselelo Zokubekezelelana Nokungaguquguquki
Ufuna izingxenye zakho zilingane kahle ngaso sonke isikhathi. I-aluminium die casting evamile ngokuvamile ikunikeza ukubekezelela phakathi kuka-±0.05 mm no-±0.10 mm. Ukuze uthole imisebenzi enemba ngempela, ungehlela ku-±0.01 mm. Amazinga omkhakha afana ne-ISO 8062-3 kanye ne-NADCA asiza ukuqondisa ukuthi yini engenzeka. Noma kunjalo,ukushaya lezo tolerances eziqinilekungaba nzima, ikakhulukazi uma udinga imiphumela efanayo kuzo zonke izingxenye.
Imikhawulo yeJiyomethri ku-Die Casting
I-Die casting isebenza kahle kakhulu emimoyeni ethile. Uma udinga amakhona acijile, izimbobo ezijulile, noma izindonga ezincane, ungase ungene enkingeni. Inqubo ikhawulela ukuthi ingxenye yakho ingaba yinkimbinkimbi kangakanani. Ngezinye izikhathi, kufanele ushintshe umklamo wakho noma wengeze izinyathelo ezengeziwe ukuze uthole izici ozifunayo.
Izinqubo Zomshini ze-CNC Zokuthuthukisa I-Aluminium Yabalingisi
I-Milling for Flatness kanye Nezindawo ezibushelelezi
Lapho ufuna eyakhoizingxenye ze-aluminiumukuze ubukeke futhi uzizwe ubushelelezi, ukugaya kwe-CNC kuwuhlelo lwakho lokuya kuyo. Imishini yokugaya isebenzisa amathuluzi abukhali, ukuphotha ukuze kuphuce izindawo ezimahhadlahhadla nokudala izindawo eziyisicaba, ezilinganayo.
