1. Kev kub ceev-ceev steel hniav, yog ib qho ntawm cov khoom sib xyaw ntawm cov hlau, kev sib piv cov khoom siv qis, yooj yim rau cov txheej txheem, muaj zog siab thiab lwm yam zoo. HSS cov hniav tuaj yeem siv tau rau ntau qhov sib txawv thiab ntau thiab tsawg kom tau raws li kev sib txawv txiav. Nyob rau hauv cov txheej txheem machining, nyob rau hauv thiaj li muab tag nrho cov kev ua yeeb yam thiab txhim kho kev pabcuam lub neej, nws yog qhov tsim nyog xaiv lub neej thiab cov cuab yeej ntsuas, thiab nqa tawm qhov tseeb thiab txij nkawm. Txawm li cas los xij, thaum txiav cov khoom siv tawv tawv thiab lub zog ua kom muaj zog, cov hnav tsis kam thiab hardness ntawm hss hss tsis tuaj yeem ua tau raws li cov cai.
2. Tungsten carbide hniav, uas nws lub chaw tseem ceeb yog tungsten carbide thiab cobalt, yog tsim los ntawm hmoov metallurgy process. Nws muaj cov yam ntxwv zoo heev xws li hardness siab, siab muaj zog, muaj peev xwm tswj tau ruaj khov nyob rau hauv cov kev ua tau zoo thiab lub neej ntev nyob rau hauv cov kev kub siab thiab hnyav txiav tej yam kev mob siab. Tungsten carbide hniav yog ua kom zoo dua los ntawm cov txheej txheem ntau lawm, thiab lawv lub hauv paus yog ua los ntawm kev sib xyaw tungsten carbide, uas yog ua tiav los ntawm kev txiav meej thiab sib tsoo cov txheej txheem. Thaum lub sij hawm machining txheej txheem, cov npoo ntawm tungsten carbide tuaj yeem raug machined rau hauv ntau yam duab thiab ntau thiab tsawg kom tau raws li cov haujlwm sib txawv.
3 Piv nrog tsoos hlau cov ntaub ntawv, cov kab sib xyaw sib xyaw ua ke tau txiav ntau dua, lub neej ntev thiab kev kho mob qis dua, uas yog qhov kev txhim kho yav tom ntej ntawm kev ua lag luam tshiab.
