1. Cov ntaub ntawv txiav: cov qauv xaiv ntawm kev txiav cov khoom, ua raws li cov kev xav tau ntawm qhov ntev.
2. Drilling, lub qhov ntawm potentiometer pob qhov rooj, siv rau nruab cov axis ntawm kev sib hloov ntawm kev sib hloov thiab phaj ruaj.
3. Sandblasting Kev Ua: rau sandblasting ua ntawm potentiometer pob qhov rooj, muaj qee qhov kev sib txhuam, ua rau nws cov ntsej muag du thiab yooj yim tig tau yooj yim.
4. Radium Vulture: Siv titanium alloy laser carving tshuab cov npe thiab ntsuas kom ua rau lub zog ua kom zoo, yooj yim rau cov neeg siv.
5. Xim: Potentiometer pob qhov rau txau xim, ua rau nws cov tsos zoo nkauj dua, thiab nce nws corrosion tsis kam.
