Izixhobo zeCeramic zeAlumina zeNkqubo yokuVuthela i-E-Gun
I-St.Cera ivelisa izinto ze-alumina ceramic ezicocekileyo kakhulu eziyi-99.8% ezenzelwe ngokukodwa iinkqubo zokufuma ze-electron beam (E-gun). Ezi nxalenye ziquka ii-crucible liners, izikhuselo ze-beam deflector, ii-insulators, kunye nezixhobo zokufakela. Ezi zinto zinika amandla aphezulu e-dielectric (15×10⁶ V/m), uzinzo lobushushu olufikelela kwi-1600°C, kunye nokumelana okuhle kakhulu nokutshatyalaliswa kobushushu kunye nokuhlaselwa ngamakhemikhali kwizinto eziphuma emkhenkceni. Amandla ethu okulungisa ngokuchanekileyo afezekisa iijometri ezintsonkothileyo ezinobukhulu obuncinci beempawu eziyi-0.2mm, ukuthamba okungu-0.003mm, kunye nokugqitywa komphezulu ongu-Ra0.1. Inxalenye nganye ihlolwe yi-100% CMM ukuze ifumane ukuchaneka kobukhulu.

- · Izikhuselo ze-beam deflector kunye neepleyiti ze-aperture
- · Izithinteli zombane kunye nezinto zokuncedisa
- · Izixhobo zokufakela imithombo yokufuma
Ukuchaneka kweMveliso:
Ukuthe tye: 0.005mm, ukuthe nkqo: 0.005mm, ukujikeleza: 0.002mm, ukugxila: 0.01mm.
Iingenelo:
- · Akukho kungcoliswa kweefilimu ezincinci ezivela kwizinto ezisetyenziswa ekutshiseni
- · Iyamelana nobushushu obuphezulu ngexesha lokufuma
- · Ubomi benkonzo ende – 5× ubude kunezinye iindlela zegrafiti
Ukwenziwa ngokwezifiso:
Iimilo zemibhobho enokubethelelwa ngokwezifiso, iiflanges zokufakela, iipateni zemingxunya, kunye nokugqitywa komphezulu ziyafumaneka.
