Hlau ua

Hlau txiav hniav yog cov cuab yeej tseem ceeb hauv kev ua haujlwm niaj hnub. Txawm hais tias nws yog ib qho cuab yeej siv tshuab zoo tib yam, lossis CNC tshuab hniav thiab lub tshuab ua haujlwm tshuab hniav, nws yuav tsum cia siab rau cov cuab yeej txiav kom tiav cov haujlwm txiav. Thaum txiav, txiav ib feem ntawm lub cuab yeej tsis tsuas yog dais ib tug loj txiav quab yuam, tab sis kuj bears lub siab kub generated los ntawm lub deformation thiab kev sib txhuam ntawm lub txiav plaub muag. Txhawm rau kom cov hniav tuaj yeem ua haujlwm nyob rau hauv cov xwm txheej zoo li no yam tsis tau deformed lossis puas tsuaj sai, thiab txhawm rau tswj nws lub peev xwm txiav, cov khoom siv ntawm cov hniav yuav tsum muaj qhov kub thiab txias hardness thiab hnav tsis kam, qhov tsim nyog khoov lub zog, cuam tshuam toughness thiab chemical zog. Inert, kev ua tau zoo (txiav, forging thiab kho cua sov, thiab lwm yam), tsis yooj yim rau deform, feem ntau thaum cov khoom hardness siab, hnav kuj yog siab; Thaum lub zog dabtsi yog khoov siab, qhov cuam tshuam toughness kuj siab. Tab sis qhov nyuaj ntawm cov khoom, qhov qis nws lub zog flexural thiab cuam tshuam toughness. Kev kub ceev hlau tseem yog cov khoom siv dav siv ntau tshaj plaws vim nws lub zog khoov siab thiab kev cuam tshuam toughness, nrog rau kev ua haujlwm zoo, ua raws li cemented carbide. Qhov thib ob, qhov kev ua tau zoo ntawm cov hniav nyob ntawm seb qhov geometric tsis ntawm qhov txiav thiab xaiv thiab tsim cov qauv ntawm cov hniav yog qhov tsim nyog.
