Yuav ua li cas ua kom raug kev sib tsoo log sib tsoo

Cov kev taw qhia kev tsheb ciav hlau yog qhov tseem ceeb tshaj plaws txhawb nqa ntawm cov khoom siv, thiab nws lub luag haujlwm hauv cov tshuab thiab cov khoom siv yog qhov tseeb ntawm nws tus kheej. Yog li ntawd, kev sib tsoo lub log yuav tsum ua tau raws li qhov yuav tsum tau ua thaum sib tsoo cov kev taw qhia rail. Kev sib tsoo log muaj cov yam ntxwv rau kev sib tsoo ntawm cov lus qhia rail. Dab tsi yog cov yam ntxwv? Cia peb saib.

Lub machining raug ntawm cov lus qhia rail ncaj qha cuam tshuam rau kev ua haujlwm raug ntawm cov tshuab thiab khoom siv. Txawm li cas los xij, cov kev taw qhia kev tsheb ciav hlau feem ntau yog nrum hollow nyias-walled qhov chaw nrog cov qauv nyuaj. Warping, dabtsi yog khoov los yog twisting deformation yog yooj yim tshwm sim nyob rau hauv qhov kev txiav txim ntawm kev sib tsoo quab yuam. Yog hais tias lub workpiece tsis raug clamped los yog nyob rau hauv tus ntawm nws tus kheej qhov hnyav, nws kuj yuav tsim loj deformation. Tsis tas li ntawd, qhov loj deformation tseem yuav tshwm sim nyob rau hauv kev cuam tshuam ntawm kev sib tsoo kub, qhov kub thiab txias qhov sib txawv thiab casting sab hauv kev ntxhov siab. Cov no yog cov teeb meem tsis zoo cuam tshuam rau kev ua haujlwm raug ntawm cov lus qhia kev tsheb ciav hlau, thiab kev tswj hwm thiab kev tiv thaiv yuav tsum tau ua. Kev ua tau zoo ntawm cov lus qhia rail nto yog siab. Piv txwv li, qhov kam rau ntawm lub txaj qhia kev tsheb nqaj hlau, txoj kev tsheb ciav hlau tiaj tus thiab qhov ncaj yog 0.008mm/1000mm nyob rau hauv lub dav hlau kab rov tav; 0.009mm / 1000mm nyob rau hauv ntsug dav hlau; Lub siab ntev ntawm V-shaped qhia rail yog 0.01mm / 750mm; Qhov saum npoo roughness tus nqi Ra ntawm kev taw qhia rail nto yog 0.4 μ M li al. Yog li ntawd, nws yog ib qho tseem ceeb heev los xaiv txoj kev sib tsoo thiab cov txheej txheem ntawm kev taw qhia rail nto.

Cov kev taw qhia rail nto feem ntau yog tsim los ntawm lub dav hlau thiab inclined dav hlau, yog li kev sib tsoo los yog lub ntsej muag kawg yog saws thaum sib tsoo. Txhawm rau txhim kho kev sib tsoo kom zoo, Ntau qhov sib tsoo lub log thiab cov cuab yeej sib tsoo lub taub hau (sib sib tsoo sab dav hlau) kuj tuaj yeem siv los ua kom pom zoo li kev sib tsoo, thiab cov lus qhia kev tsheb nqaj hlau tuaj yeem ua hauv av hauv ib lub sijhawm nrog kev sib tsoo zoo li lub log. Obviously, ntau lub log zoo li kev sib tsoo thiab sib xyaw ua ke zoo li kev sib tsoo log sib tsoo muaj kev sib tsoo siab, tab sis cov qauv ntawm kev sib tsoo lub taub hau yog qhov nyuaj thiab tsim nyog rau ntau lawm. Cov saum toj no yog kev sib koom ntawm kev sib tsoo log sib tsoo. Yog tias koj xav tau rov luam dua, thov kos rau ntawm no
