21.15 Puas yog cov khoom siv ductility tseem ceeb rau kev ua haujlwm? … Ductility ncaj qha cuam tshuam rau hom nti tsimuas, dhau los, cuam tshuam rau saum npoo, qhov xwm txheej ntawm cov khoom siv (cov ntaub ntawv tsawg dua tuaj yeem ua rau cov cuab yeej sib tham), thiab cov ntaub ntawv ductile ntau ntxiv. chips uas tej zaum yuav tsis yooj yim los tswj.

Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev siv lub tshuab ua haujlwm siab ceev tuaj yeem ua haujlwm nrawm yam tsis siv cov kua txiav?

Yog. Lub hom phiaj tseem ceeb ntawm cov kua txiav yog kom lubricate thiab tshem tawm cov cua sov, feem ntau ua tiav los ntawm dej nyab cov cuab yeej thiab cov khoom ua haujlwm los ntawm cov kua dej. Nyob rau hauv kev kub ceev machining, feem ntau ntawm cov cua sov yog xa los ntawm tej cheeb tsam los ntawm lub nti, yog li qhov yuav tsum tau rau ib tug txiav kua yog tsawg.

Cov khoom siv twg yog qhov tsim nyog rau kev cuam tshuam kev ua haujlwm Vim li cas?

cuam tshuam kev ua haujlwm txiav ib txwm yuav tsum tau txiav cov cuab yeej uas muaj siab cuam tshuam lub zog (tawv tawv) nrog rau cov thermal-shock tsis kam.

Thaum machining cov khoom nkig cov chips tsim yog?

Machining ntawm nkig cov ntaub ntawv xws li cam khwb cia hlau ua cov hom chips. me me yog tsim vim tsis muaj ductility ntawm cov khoom. Kev sib txhuam ntawm cov cuab yeej thiab cov nti txo, ua rau kom zoo dua qhov tiav. 2.

Vim li cas nws tsis yog ib txwm pom zoo kom nce kev txiav nrawm txhawm rau txhawm rau nce qhovproductivity?

Vim li cas nws tsis yog ib txwm pom zoo kom nce kev txiav nrawm txhawm rau txhawm rau nce tus nqi ntau lawm? … Kev txiav nrawm dua kuj ua rau cov flank hnav, thiab yuav ua rau kub siab ntawm lub cuab yeej-workpiece interface.
