Precision machining, tsis yog cov ntaub ntawv dab tsi tuaj yeem ua tau precision machining, xws li qee cov ntaub ntawv uas nyuaj heev yog tias lawv dhau qhov hardness ntawm machined qhov chaw, qee cov ntaub ntawv tshwj xeeb tsis haum rau precision precision machining. Yog li dab tsi yog cov kev cai tshwj xeeb ntawm precision machining ntawm cov khoom? Hauv qab no los ntawm kuv los qhia koj rau hauv qab no.
Ua ntej yog qhov yuav tsum tau ntawm cov khoom siv hardness, rau qee lub sijhawm, qhov siab dua qhov hardness ntawm cov khoom yog qhov zoo dua, tsuas yog txwv rau cov hardness yuav tsum tau ntawm lub tshuab ua tiav, cov khoom ua tiav tsis tuaj yeem nyuaj, yog tias hardness dua lub tshuab. qhov chaw tseem ua tsis tau.
Qhov thib ob, cov khoom siv yog mos thiab nyuaj me ntsis, tsawg kawg yog ib qib qis dua qhov hardness ntawm lub tshuab, tab sis kuj nyob ntawm lub luag haujlwm ntawm cov cuab yeej ua tiav yog ua li cas nrog lub tshuab tsim nyog xaiv cov ntaub ntawv.
Nyob rau hauv luv luv, precision machining ntawm cov ntaub ntawv uas yuav tsum tau los yog ib co, tsis yog dab tsi cov ntaub ntawv uas yog tsim nyog rau kev ua, xws li cov khoom muag heev los yog tawv heev, lub qub tsis tsim nyog rau kev ua, thiab lub tom kawg yog tsis tiav.
Yog li ntawd, qhov yooj yim tshaj plaws yog nyob rau hauv lub tshuab tej xeem ua nroj tsuag ua ntej cov khoom siv, yog tias lub ntom ntom nti, yog tias lub zog loj dhau lawm, thiab lub hardness yog ntau tshaj lub tshuab (lub tshuab dhos tig lub cuab yeej) hardness, tsis tuaj yeem ua tiav, tsis tsuas yog yuav ua rau cov khoom puas, tab sis kuj ua rau muaj kev phom sij, xws li tig lub cuab yeej ya tawm ntawm kev sib tsoo raug mob. Yog li ntawd, feem ntau hais lus, rau kev siv tshuab, cov khoom siv yuav tsum qis dua qhov hardness ntawm lub tshuab cuab yeej, kom nws tuaj yeem ua tiav.
