Pali mankhwala angapo pamwamba omwe angagwiritsidwe ntchito CNC machined mbali zotayidwa.Mtundu wa mankhwala ogwiritsidwa ntchito udzadalira zofunikira zenizeni za gawolo ndi mapeto omwe akufuna.Nawa mankhwala odziwika bwino amtundu wa aluminiyamu wa CNC:
1. Anodizing / Hard anodized
Iyi ndi njira yomwe oxide wosanjikiza amakula pamwamba pa aluminiyumu.Anodizing imatha kupangitsa kuti ikhale yolimba, yosachita dzimbiri yomwe imatha kupakidwa utoto wamitundu yosiyanasiyana.Itha kukhala yomveka bwino, yakuda, yofiyira, yabuluu, yofiirira, yachikasu kapena mitundu ina iliyonse yomwe mungafune malinga ndi kapangidwe kanu.
2. ALTEF (Teflon)
ALTEF(Teflon) ndi mtundu wa njira zochizira pamwamba zomwe zimagwiritsidwa ntchito pazigawo zamakina za CNC.Imayimira Aluminium Teflon Electroless Nickel Plating, ndipo imaphatikizapo kuyika nickel woonda wa electroless pamwamba pa gawo la aluminiyumu, ndikutsatiridwa ndi wosanjikiza wa Teflon.
Njira ya ALTEF imagwiritsidwa ntchito kupititsa patsogolo kukana kovala ndikuchepetsa kugundana kwa zigawo za aluminiyamu.Chosanjikiza cha nickel cha electroless chimapereka malo olimba, osagwirizana ndi dzimbiri omwe amathandizira kuti gawolo likhale lolimba, pomwe wosanjikiza wa Teflon umachepetsa kugundana pakati pa gawo ndi malo ena, kuwongolera mawonekedwe a gawolo.
Njira ya ALTEF imagwira ntchito poyeretsa kaye gawo la aluminiyamu kuti lichotse zonyansa zilizonse.Gawolo limamizidwa mumtsuko womwe uli ndi ma electroless nickel plating chemicals, omwe amayika faifi wosanjikiza pamwamba pa gawolo kudzera munjira ya autocatalytic.Nickel wosanjikiza nthawi zambiri amakhala mozungulira ma microns 10-20.
Kenaka, gawolo limamizidwa mu yankho lomwe lili ndi tinthu tating'ono ta Teflon, zomwe zimamatira ku nickel wosanjikiza ndikupanga chigawo chochepa kwambiri cha Teflon pamwamba pa gawolo.Zosanjikiza za Teflon nthawi zambiri zimakhala pafupifupi ma microns 2-4.
Zotsatira za njira ya ALTEF ndizovala kwambiri komanso zosasunthika pang'onopang'ono pa gawo la aluminiyamu, lomwe ndi loyenera kuti ligwiritsidwe ntchito pazochitika zapamwamba komanso zolondola, monga ndege, magalimoto, ndi mafakitale azachipatala.
3. Kupaka ufa
Iyi ndi njira yomwe ufa wowuma umayikidwa pamwamba pa aluminiyumu ndikuwotcha kuti ukhale wokhalitsa, wokongoletsera.
4. Kupukuta kwa Chemical
Njirayi imagwiritsa ntchito mankhwala kuchotsa zinthu zochepa kuchokera pamwamba pa aluminiyumu kuti apange mapeto osalala, owala.
5. Makina opukuta
Kuchita zimenezi kumaphatikizapo kugwiritsa ntchito ma abrasives angapo kuchotsa zinthu pamwamba pa aluminiyumu kuti apange mapeto osalala, owala.
6. Kuwombera mchenga
Kuchita zimenezi kumaphatikizapo kugwiritsa ntchito mpweya wothamanga kwambiri kapena madzi kuphulitsa mchenga kapena zinthu zina zowonongeka pamwamba pa aluminiyumu kuti apange mapeto ake.
