Qhov tsawg tshaj plaws laum me me muaj nyob ntawm seb hom thiab ntsuas qhov siv tau. Nov yog qee qhov me me uas muaj nyob hauv ntau pawg:
Qhov tsawg tshaj plaws Drill Bit Sizes
Thaum drilling qhov me me heev, kev xaiv ntawm cov khoom siv thiab cov txheej txheem yog qhov tseem ceeb rau kev ua tiav qhov tseeb thiab kev ua haujlwm zoo. Nov yog qee cov ntaub ntawv zoo tshaj plaws thiab cov txheej txheem rau lub hom phiaj no:
Cov ntaub ntawv Drilling Extremely Small Qhov
Polycrystalline Pob Zeb Diamond (PCD):
PCD laum cov khoom siv tau zoo heev rau drilling hauv cov ntaub ntawv nyuaj xws li ceramics, silicon, thiab lwm yam tawv substrates. Lawv muaj kev hnav zoo heev thiab tuaj yeem tswj tau cov npoo ntse hla dhau kev siv txuas ntxiv, ua rau lawv haum rau micro drilling daim ntaub ntawv hauv kev lag luam xws li semiconductors.
Tungsten Carbide:
Cov cuab yeej tungsten carbide feem ntau yog siv vim lawv qhov nyuaj thiab muaj peev xwm tiv taus qhov kub thiab txias. Lawv muaj txiaj ntsig zoo rau kev khawb me me hauv cov hlau thiab cov ntaub ntawv abrasive tab sis tuaj yeem hnav sai sai thaum siv cov ntaub ntawv nyuaj zoo sib xws.
High-Speed Steel (HSS):
HSS laum khoommuaj ntau yam thiab siv tau rau ntau yam ntaub ntawv, nrog rau cov hlau softer thiab yas. Txawm hais tias lawv yuav tsis kav ntev npaum li cov carbide lossis PCD cov khoom hauv cov ntawv siv tawv, lawv feem ntau raug nqi ntau dua rau kev siv dav.
Pob zeb diamond-coated khoom:
Cov khoom no muab cov tawv tawv ntawm pob zeb diamond nrog cov khoom siv substrate, ua rau lawv haum rau drilling rau hauv cov ntaub ntawv nyuaj heev xws li iav thiab ceramics. Txawm li cas los xij, lawv tuaj yeem nkag siab rau overheating
