Kev tsim khoom ntawm Machinery Parts
Hauv Kev Tsim Cov Khoom Siv Machinery, cov kev xav tau ntawm machining precision yog siab heev, thiab kev ua haujlwm yuam kev ntawm kev tswj yuav cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom siv tshuab thiab kev ua haujlwm zoo, yog li hauv daim ntawv no, qhov tseeb machining ntawm lub tswv yim no tau ua tiav. cov lus qhia yooj yim, tib lub sijhawm, los ntawm lub kaum sab xis ntawm cov cuab yeej siv tshuab, cov cuab yeej machining xws li ob peb yam tseem ceeb cuam tshuam rau kev ua haujlwm raug ntawm lub tshuab qhov chaw raug tshuaj xyuas, thiab ntawm qhov no tso rau pem hauv ntej qee qhov kev lees paub, txoj hauv kev zoo los txhim kho cov tshuab qhov kev ua precision.
Summary of The Machining Accuracy
Mechanical qhov chaw machining qhov tseeb yog hais txog cov khoom siv kho tshuab hauv kev ua tiav, cov khoom xws li qhov loj me, cov duab, qhov sib txawv ntawm qhov tseeb tsis thiab cov qauv tsim, xws li qhov tseeb qhov ntsuas thiab kev xav ntawm cov lej sib txawv ntawm cov qauv tsim thiab lwm yam. ntawm qhov tseeb machining yog qis dua, thiab thaum qhov tseeb parameter thiab txoj kev xav ntawm cov lej sib txawv ntawm cov qauv tsim ntawm cov khoom me me los yog tag nrho zoo ib yam, sawv cev rau kev ua haujlwm siab precision machinery qhov chaw ua haujlwm, tsuas yog qhov tseeb machining thiab tsis zoo cuam tshuam nrog cov lej tsis sib txawv, tsis muaj qhov sib txawv me me, qhov siab dua qhov precision.
Qhov thib ob, lub ntsiab yam tseem ceeb cuam tshuam rau cov neeg kho tshuab qhov chaw machining raug
(a) spindle rotation yuam kev
Nyob rau hauv niaj hnub mechanical processing ntau lawm, machinery qhov chaw ua system yog tsim los ntawm lub tshuab cuab yeej, tej cuab yeej, jig thiab artifacts ntawm ob peb qhov chaw, tsis hais txog ntawm ib feem ntawm tus thawj yuam kev tshwm sim los yog deformation, thiab lwm yam, yuav ncaj qha cuam tshuam rau machining precision. mechanical qhov chaw, nyob rau hauv uas tus yuam sij rau kev cuam tshuam ntawm lub tshuab cuab yeej, thiab qhov yuam kev ntawm spindle yog ib feem ntawm lub tshuab cuab yeej yuam kev.
Hauv kev tsim cov khoom siv tshuab, raws li qhov tseem ceeb ntawm cov cuab yeej siv tshuab spindle tuaj yeem txuas ntxiv ua cov lus tsa suab, nyob rau hauv txoj kev xav, spindle nyob rau hauv lub axis ntawm cov lus tsa suab yog ruaj khov rau ntawm txoj kab ncaj nraim, txawm li cas los xij, vim muaj kev vibration, bearing, spindle manufacturing yuam kev. , cov yam ntxwv ntawm lub lubrication mob, kev cuam tshuam ntawm axis, qhov tseeb, tseem yuav muaj kev hloov pauv, thiab qhov no yog lub ntsiab ntawm qhov yuam kev ntawm spindle. Kev ua yuam kev feem ntau muab faib ua qhov yuam kev roundness ntawm spindle, voj voog yuam kev, ncaj nraim yuam kev, yuam kev ntawm qhov loj me, geometric eccentric, haum clearance.
Xws li kev xav, kev ua yuam kev ntawm ntau hom kev sib txawv ntawm cov khoom siv yuav txawv, xws li thaum lub spindle nyob rau hauv cov lus tsa suab, yog radial round beating los ntawm kev ua yuam kev, yog li yuav cuam tshuam rau lub workpiece, uas ua rau ib tug roundness yuam kev; Thiab thaum lub ntsiab ncej nyob rau hauv lub rotary motion ntawm viav vias lub kaum sab xis, yuav ua rau lub kaum sab xis ntawm cov artifacts tshwm teeb meem, uas cuam tshuam rau lub dav hlau duab ntawm txhua yam khoom.
