Siab -Speed Steel
High-ceev steel yog ib qho ntawm cov khoom siv feem ntau siv rau arc- lub kaum sab xis laum khoom. Cov khoom no muaj cov hardness siab, toughness, thiab zoo thermal stability, tso cai rau lub laum me ntsis kom ruaj khov thiab durability thaum lub sij hawm siab - ceev tig. High-ceev steel arc- lub kaum sab xis laum khoom yog tsim rau drilling qhov ntiav hauv cov hlau, cam khwb cia hlau, thiab lwm yam ntaub ntawv. Nws qhov zoo muaj xws li tus nqi qis thiab yooj yim ntawm kev ua thiab kho. Txawm li cas los xij, siab -cov cuab yeej siv ceev steel muaj qhov hnav tsis zoo thiab yuav tsum tau hloov tom qab siab{10}} thauj khoom lossis siv ntev.
Carbide
Carbide arc- lub kaum sab xis laum cov khoom zoo tshaj plaws hauv qhov tawv thiab hnav tsis kam. Cov khoom siv no yog tsim los ntawm cov khoom siv tawv tawv ntawm cov hlau refractory thiab cov hlau khi los ntawm cov hmoov hlau metallurgy, muaj cov hardness siab heev thiab zoo thaum tshav kub kub. Carbide laum khoom yog tsim rau drilling qhov tob hauv cov alloys nyuaj, cam khwb cia hlau, thiab stainless hlau, muab lub neej ntev kev pab cuam thiab ntau dua drilling efficiency. Piv nrog rau siab -ceev steel, carbide laum khoom yog kim dua, tab sis lawv qhov ruaj khov nyob rau hauv siab loads thiab hnyav ib puag ncig yog superior.
Ceramic
Ceramic arc- lub kaum sab xis laum cov khoom ua tiav qib siab ntawm hardness thiab hnav tsis kam. Ceramic laum khoom yog tsim los ntawm ultra- cov ntaub ntawv nyuaj xws li txhuas oxide thiab silicon nitride, muaj zog compressive heev thiab hnav tsis kam. Hom laum no yog tsim rau kev sib sib zog nqus thiab cov ntaub ntawv nyuaj, xws li ceramics, iav, thiab quartz. Ceramic laum khoom muaj qhov ua tau zoo heev thiab raug txiav zoo, ua tau raws li qhov xav tau ntawm siab - precision drilling. Txawm li cas los xij, cov laum ceramic yog cov kim kim thiab nkig, xav tau kev saib xyuas tshwj xeeb kom tsis txhob muaj kev cuam tshuam thiab kev sib tsoo thaum siv.
