Dab tsi yog cov khoom siv cuab yeej siv hauv kev sib tsoo?

Cov cuab yeej siv hauv cov cuab yeej sib tsoo muaj xws li high-speed steel, hmoov metallurgy high-speed steel, nyuaj alloy, PCD, CBN, cermet thiab lwm yam ntaub ntawv superhard. Cov cuab yeej siv hlau ceev ceev yog qhov ntse thiab muaj lub zog zoo, thaum cov cuab yeej carbide muaj siab hardness tab sis tsis zoo toughness. Qhov ceev ntawm carbide NC cuab yeej yog pom tseeb siab dua li ntawm cov cuab yeej high-speed steel. Ob cov ntaub ntawv no yog cov ntaub ntawv tseem ceeb rau kev xyaum, reamers, milling inserts thiab kais. Kev ua tau zoo ntawm cov hmoov metallurgy kev kub ceev hlau yog nruab nrab ntawm ob cov ntaub ntawv saum toj no, uas yog siv los tsim cov milling cutter thiab kais.

Kev kub ceev steel cov cuab yeej tsis rhiab rau kev sib tsoo vim lawv qhov zoo toughness. Txawm li cas los xij, carbide NC hniav yog siab hardness thiab nkig, rhiab heev rau kev sib tsoo, thiab ntug yog yooj yim dhia. Yog li ntawd, nyob rau hauv txoj kev sib tsoo, kev khiav hauj lwm thiab kev tso kawm ntawm cov cuab yeej cemented carbide yuav tsum tau ceev faj heev los tiv thaiv kev sib tsoo ntawm cov cuab yeej lossis cov cuab yeej poob.

Vim hais tias cov precision ntawm high-speed steel cov cuab yeej yog tsawg, lawv cov kev sib tsoo yuav tsum tsis siab, thiab lawv cov nqi tsis siab, ntau manufacturers teem lawv tus kheej cov cuab yeej rhiav mus zom lawv. Txawm li cas los xij, cov cuab yeej cemented carbide feem ntau yuav tsum tau xa mus rau qhov chaw sib tsoo kev sib tsoo. Raws li kev txheeb cais ntawm qee qhov chaw sib tsoo hauv tsev, ntau dua 80% ntawm cov cuab yeej xa mus kho yog cov cuab yeej cemented carbide.
