Txij li thaum xyoo 1980s, cov yam ntxwv zoo tshaj plaws ntawm kev tsim cov cemented carbide kev lag luam hauv ntiaj teb no yog raws li hauv qab no: ntawm ib sab, cov coated cemented carbide tau tsim sai heev, nws cov zis tau nce ntau, thiab nws daim ntawv thov teb tau txuas ntxiv nthuav dav, thiab nws tau ua tiav siv rau cov txheej txheem machining hnyav xws li txiav.

Nrog rau txoj kev loj hlob sai ntawm kev lag luam hluav taws xob thiab kev lag luam kev lag luam, ultra-nplua cemented carbide tau tsim sai heev hauv xyoo 1980s, nrog kev txhim kho zoo thiab txuas ntxiv ntawm cov khoom tsim tawm.

Lwm tus yam ntxwv ntawm txoj kev loj hlob ntawm cemented carbide kev lag luam nyob rau hauv lub ntiaj teb no nyob rau hauv lub xyoo 1980s yog cov cemented carbide khoom yog tsim nyob rau hauv cov kev taw qhia ntawm precision thiab miniaturization.

Cov kev xav tau ntawm kev txiav cov cuab yeej qhov tseeb kuj yog siab dua thiab siab dua. Qee cov tuam txhab lag luam siab heev tau tshem tawm cov txheej txheem precision ntawm u-qib cemented carbide inserts. Nyob rau tib lub sijhawm, qhov tseeb qhov tseeb ntawm ntau cov cemented carbide tuag tau mus txog qib micron thiab qib ultra micron. Tsis tas li ntawd, automation thiab kev txawj ntse ntawm cov khoom siv thiab cov kab ntau lawm tau txhawb txoj kev loj hlob ntawm cemented carbide kev lag luam hauv ib qho tshiab thiab siab dua.
