TWIST DRILL

Cov khoom siv ntawm kev sib tw twist feem ntau yog nyob ntawm daim ntawv thov thiab cov khoom siv, feem ntau muab faib ua high-speed steel, carbon steel thiab tungsten steel.HSS yog qhov zoo rau cov hlau tawv thiab ntoo, thaum carbon hlau zoo dua rau cov ntaub ntawv zoo li softwoods thiab cov hlau dawb.Tungsten steel twist drills tuaj yeem siv los xyaum qhov tob thiab ntev thiab xyaum ua cov hlau zoo hlau thiab ceramics nrog cov hardness siab.

Ua tib zoo mloog cov ntsiab lus hauv qab no thaum siv twist xyaum:

1. Xaiv qhov tsim nyog twist xyaum: xaiv qhov tsim nyog twist xyaum raws li cov ntaub ntawv sib txawv thiab drilling diameters.

2. Pre-drilling kev kho mob: npaj ib tug haum drilling template, thiab ua tus cwj pwm, ntsuas thiab cim raws li yuav tsum tau.

3. Siv cov kua txiav kom raug: xaiv cov kua txiav tsim nyog raws li cov khoom siv drilling kom ntseeg tau tias lub laum me ntsis ua haujlwm zoo tshaj plaws thiab tiv thaiv kev hnav ntau dhau.

4. Txhim khu kev tiv thaiv kev nyab xeeb: Hnav cov khoom tiv thaiv tsim nyog xws li cov hnab looj tes tiv thaiv thiab tsom iav thaum lub sij hawm drilling kom tsis txhob raug mob qhov muag thiab tes.Nyob rau tib lub sijhawm, nws tseem yuav tsum tau ua tib zoo saib xyuas cov yam ntxwv ntawm kev nyab xeeb xws li cov khoom siv hluav taws xob thiab cov xaim hluav taws xob ntawm cov laum hluav taws xob.
