Precision mechanical qhov chaw thiab kev ua haujlwm

Lub hardness ntawm cov khoom siv machining muaj qhov cuam tshuam tseem ceeb rau kev ua haujlwm ntawm precision mechanical qhov chaw. Thaum cov khoom raug machined nyuaj heev, nws tuaj yeem ua rau cov cuab yeej hnav thiab kev puas tsuaj, uas tuaj yeem ua rau lub ntsej muag tsis zoo lossis txawm tias tawg ntawm lub cuab yeej. Qhov no tuaj yeem ua rau muaj teeb meem nrog qhov tseeb, qhov tseeb, thiab qhov zoo ntawm cov khoom kawg.

Ntawm qhov tod tes, thaum cov khoom siv yog mos heev, nws tuaj yeem ua rau muaj teeb meem nrog kev tshem tawm cov nti thiab tuaj yeem ua rau muaj teeb meem nrog qhov tseeb, qhov tseeb, thiab qhov zoo ntawm cov khoom kawg. Hauv ob qho tib si, cov khoom siv tuaj yeem muaj kev cuam tshuam loj rau cov txheej txheem machining.

Cov khoom hardness kuj cuam tshuam rau kev txiav, xws li txiav ceev, pub tus nqi, thiab qhov tob ntawm kev txiav. Rau cov ntaub ntawv nyuaj, kev txiav qeeb qeeb thiab cov nqi pub me me yuav tsum tau zam kom tsis txhob siv cov cuab yeej siv, thaum cov ntaub ntawv softer, txiav ceev dua thiab cov khoom noj loj dua tuaj yeem ua tau. Qhov tob ntawm kev txiav kuj yuav tsum tau kho kom haum raws li kev tshem tawm cov nti thiab tiv thaiv cov cuab yeej tawg.

Tsis tas li ntawd, cov cuab yeej siv rau kev siv machining kuj yuav tsum tau ua kom haum rau qhov hardness ntawm cov khoom siv ua haujlwm. Piv txwv li, rau cov ntaub ntawv nyuaj, cov cuab yeej txiav carbide tau nyiam, thaum rau cov ntaub ntawv softer, cov cuab yeej siv high-speed steel (HSS) yuav raug siv.

Hauv kev xaus, qhov hardness ntawm cov khoom siv machining muaj feem cuam tshuam rau qhov zoo ntawm cov txheej txheem machining thiab cov khoom kawg. Nws yog ib qho tseem ceeb los txiav txim siab qhov tsim nyog txiav tsis thiab cov cuab yeej siv raws li qhov nyuaj ntawm cov khoom siv los ua kom ntseeg tau qhov zoo tshaj plaws ntawm cov txheej txheem machining.
