Lub hom phiaj ntawm machining mechanical qhov chaw yog los pab tib neeg sai, tshwj xeeb tshaj yog cov precision ntawm qhov chaw machining; Raws li cov khoom tseem ceeb ntawm cov khoom siv, qhov precision ntawm cov khoom cuam tshuam rau qhov zoo ntawm cov tshuab, yog tias lub machining precision tsis ua raws li cov kev cai, nws yuav zoo li tias cov khoom tsis sib xws thaum lub sij hawm tag nrho cov txheej txheem sib dhos; Txhawm rau kom ntseeg tau tias kev ua tiav ntawm tag nrho cov txheej txheem ntawm kev sib dhos tshuab, nws yog ib qho tsim nyog los txhim kho qhov kev txiav txim siab ntawm cov cuab yeej siv tshuab. Kev txhim kho ntawm precision tuaj yeem ua rau lub tshuab smoother thaum nws muab tso rau hauv kev siv tom qab thiab txo qhov kev puas tsuaj ntawm qhov chaw, yog li txhawb lub tshuab kom muaj kev pabcuam ntev dua. Lub tuam txhab kev nqis peev hauv kev kho tshuab yuav raug txo kom tsawg, kev tsim khoom ntawm cov tshuab machining yuav tau nce ntau, thiab lub tuam txhab kev lag luam kev lag luam yuav zoo dua. Tsis tas li ntawd, kev txhim kho ntawm cov khoom ua haujlwm raug ua tau raws li qhov yuav tsum tau ua ntawm kev txhim kho ntawm cov neeg niaj hnub thiab lub teb chaws, yog li kev txhim kho ntawm kev ua tiav tsis tuaj yeem ncua sijhawm.
Qhov tseeb thiab qhov yuam kev yog cov cim tseem ceeb los ntsuam xyuas cov yam ntxwv ntawm kev ua haujlwm ntawm cov khoom siv kho tshuab, thiab qib kam rau ua tau nruj me ntsis rau kev tsim cov qhov, shafts, thiab lwm yam. Qib siab kuj yog lub ntsiab lus ntawm qhov raug; qhov siab dua qhov tseeb, qhov me dua tus qauv tus nqi ntawm qhov ntev ntev. Machining yuam kev tsuas tuaj yeem txo qis thiab tsis tuaj yeem tshem tawm tag nrho. Qhov tseeb yog tau los ntawm kev sib piv cov yam ntxwv tseem ceeb ntawm cov khoom tsim thiab ua tiav cov tshuab geometry nrog cov duab kos duab. Qhov tseeb suav nrog cov txheej txheem saum npoo ntawm lub tshuab, uas yuav tsum tau muab piv nrog cov qauv kev daws teeb meem. Hloov pauv raws li tus qauv tso cai, qhov tseeb kom ua tau raws li cov kev cai; qhov tseeb, xws li tib lub axis degree, parallelism, thiab lwm yam, kev tswj nruj ntawm cov duab raug tsim nyog tuaj yeem ua kom ntseeg tau qhov zoo ntawm cov khoom siv; qhov tseeb, uas yog thiab cov qauv kev npaj ua ib qho kev sib piv, flatness, flatness, thiab lwm yam yog tag nrho cov qhov tseeb.
Mechanical qhov chaw ua, tsis tsuas yog ua haujlwm raws li ntau yam kev qhia tshwj xeeb, tab sis kuj suav nrog cov xwm txheej tshwj xeeb ntawm kev tsim khoom thiab kev ua haujlwm; nyob rau hauv qhov kev tso cai los ntawm cov specifications, cov kev hloov kho. Qhov nce hauv precision sawv cev nce nqi ntawm cov khoom. Thaum txhim kho qhov tseeb, qhov kev tsim khoom zoo thiab kev ua haujlwm yuav tsum tau tsim raws li cov xwm txheej tshwj xeeb ntawm kev ua cov nroj tsuag kom ntseeg tau tias qhov kev ua tau zoo tuaj yeem txhim kho tau zoo nrog cov peev nyiaj tsawg. Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho, Tuam Tshoj txoj kev lag luam machining tau qhia ntau yam zoo heev thiab cov khoom siv ntau lawm. Lub tuam txhab tseem tuaj yeem tau txais txiaj ntsig zoo ntawm kev lag luam los ntawm kev txo qis kev tsim khoom thiab kev ua haujlwm tsis raug thiab txhim kho qhov zoo ntawm cov tshuab.
