Muab ob npaug rau-sided sib tsoo, raws li txoj hauv kev tseem ceeb rau siab -precision planar machining, tso cai rau kev sib tsoo ib txhij ntawm ob qhov chaw ntawm ib qho chaw ua haujlwm hauv ib qho kev teeb tsa, uas ua rau cov thickness zoo sib xws, flatness, thiab nto zoo. Txawm li cas los xij, cov txheej txheem no muaj cov kev cai nruj heev ntawm cov khoom siv, cov txheej txheem tsis ua haujlwm, thiab cov txheej txheem ua haujlwm. Kev tsis saib xyuas txhua kauj ruam tuaj yeem ua rau txo qis qhov tseeb, qhov tsis xws luag, lossis txawm tias cov khoom puas tsuaj. Txhawm rau kom muaj kev ruaj ntseg thiab kev ntseeg tau ntawm ob -sab hauv av machining ntawm qhov chaw, ntau yam tseem ceeb yuav tsum tau ua tib zoo saib.
Ua ntej, qhov tseeb thiab kev saib xyuas ntawm kev sib tsoo disc yog qhov tseem ceeb. Lub flatness ntawm kev sib tsoo disc ncaj qha txiav txim siab parallelism thiab thickness uniformity ntawm ob sab ntawm lub workpiece. Yog li ntawd, ua ntej machining, lub disc nto yuav tsum tau kuaj xyuas rau khawb, dents, los yog lub zos hnav, thiab kho tam sim ntawd. Thaum lub sij hawm kho, cov cuab yeej kho kom tsim nyog thiab cov khoom noj yuav tsum raug xaiv kom tsis txhob ua rau tag nrho cov flatness ntawm lub disc nto vim txiav ntau dhau. Nyob rau tib lub sijhawm, qhov sib tsoo disc nto yuav tsum tau ua kom huv si kom tsis txhob sib tsoo cov khib nyiab thiab cov khoom txawv teb chaws los ntawm kev kos rau hauv cov khoom ua haujlwm lossis ua rau khawb thaum lub sijhawm ua haujlwm.
Qhov thib ob, lub workpiece yuav tsum tau ruaj ntseg clamped thiab positioned nrog uniform quab yuam. Muab ob npaug rau-sided sib tsoo yuav tsum muaj siab sib xws hauv clamping quab yuam. Loose clamping tuaj yeem ua rau cov khoom txav txav los yog kev co, thaum clamping ntau dhau tuaj yeem ua rau elastic deformation lossis txawm tias tawg hauv nyias - phaj phaj. Cov khoom siv tsim nyog yuav tsum raug xaiv raws li cov khoom siv ua haujlwm, tuab, thiab cov duab, thiab cov khoom siv sib tw yuav tsum tau ua ua ntej ua cov txheej txheem los xyuas kom meej qhov chaw ruaj khov thiab sib npaug sib npaug.
Kev teeb tsa ntawm cov txheej txheem tsis zoo yog qhov tseem ceeb rau kev ua kom muaj kev ua tau zoo. Kev sib tsoo siab, kev sib hloov ceev (nrog rau kev sib hloov thiab kiv puag ncig ntawm lub sab sauv thiab sab hauv kev sib tsoo discs), lub sijhawm ua haujlwm, thiab kev sib tsoo cov kua dej yuav tsum tau txiav txim siab raws li cov khoom siv ua haujlwm, qhov tseeb thawj zaug, thiab xav tau qhov chaw roughness. Lub siab dhau los lossis lub sijhawm tuaj yeem ua rau dhau - sib tsoo thiab kub hnyiab, thaum lub siab tsis txaus tuaj yeem tiv thaiv qhov kev ua tiav ntawm qhov xav tau flatness thiab tshem tawm tus nqi. Cov dej sib tsoo yuav tsum tsis yog tsuas yog muab cov cua txias thiab lubrication tab sis kuj muaj kev tu kom zoo thiab muaj peev xwm tshem tawm slag. Nws cov concentration thiab huv huv yuav tsum tau kuaj tsis tu ncua kom tsis txhob muaj kev puas tsuaj los ntawm kev cuam tshuam rau kev ua tiav.
Kev tswj ib puag ncig thaum ua haujlwm kuj tseem ceeb. Qhov kub thiab txias hloov ua rau thermal expansion thiab contraction ntawm kev sib tsoo disc thiab workpiece, cuam tshuam qhov tseeb qhov tseeb thiab parallelism. Qhov zoo tshaj plaws, kev ua haujlwm yuav tsum tau ua nyob rau hauv qhov kub thiab txias -tswj kev cob qhia, lossis cov khoom siv yuav tsum tau preheated thiab kub - them nyiaj. Tsis tas li ntawd, cov plua plav thiab kev co hauv qhov chaw ua haujlwm huab cua yuav tsum raug cais kom ntau li ntau tau kom tsis txhob cuam tshuam nrog lub siab - precision sib tsoo disc thiab ntsuas qhov system.
Kev tshuaj xyuas zoo thiab kev saib xyuas cov txheej txheem yuav tsum tau ua nyob rau hauv tag nrho cov txheej txheem machining. Thaum lub sij hawm thawj zaug -cov khoom thiab cov sij hawm soj ntsuam xyuas, cov cuab yeej ntsuas qhov tseeb (xws li micrometers, ntsuas cov ntsuas pav ca, lossis cov khoom siv kho qhov muag) yuav tsum tau siv los txheeb xyuas seb qhov thickness, flatness, thiab parallelism puas tau raws li qhov yuav tsum tau ua. Yog tias pom qhov txawv txav txawv txav, lub tshuab yuav tsum raug tso tseg tam sim ntawd txhawm rau txheeb xyuas qhov ua rau, kho cov txheej txheem tsis zoo, lossis xyuas cov khoom siv kom tsis txhob muaj cov khoom tsis xws luag.
Thaum kawg, cov neeg ua haujlwm thiab cov neeg ua haujlwm saib xyuas yuav tsum tau txais kev cob qhia kev cob qhia thiab paub txog cov khoom siv, cov qauv txheej txheem, thiab cov txheej txheem kev nyab xeeb. Kev ua haujlwm tsis raug yuav tsis tsuas yog txo qhov raug ntawm machining, tab sis kuj tseem tuaj yeem ua rau muaj kev nyab xeeb. Kev tu cov cuab yeej tsis tu ncua thiab kev sib tsoo disc hnav kuj tseem tsim nyog ntsuas los tswj kev ua haujlwm ruaj khov thiab yuav tsum tau muab tso rau hauv kev tswj hwm tus qauv.
Hauv cov ntsiab lus, kev ceev faj rau ob -sab sib tsoo machining ntawm qhov chaw npog cov yam xws li disc mob, clamping thiab positioning, txheej txheem tsis, kev tswj ib puag ncig, kev tshuaj xyuas zoo, thiab kev tswj cov neeg ua haujlwm. Tsuas yog los ntawm kev tswj hwm nruj me ntsis txhua kauj ruam peb tuaj yeem ua tiav cov txiaj ntsig zoo ntawm cov txheej txheem no, ua kom ruaj khov thiab txhim khu kev qha cov khoom zoo, thiab muab cov khoom lag luam lav rau siab -kawg tsim.
