Vim li cas thiab kev daws teeb meem rau kev sib tsoo cov cua sov
Nyob rau hauv lub tshav pob ntawm kev ua tiav, kev sib tsoo yog ib qho siv high-precision machining kev sib tsoo txheej txheem thaum lub sij hawm sib tsoo tuaj yeem muaj qhov cuam tshuam tseem ceeb ntawm kev ua haujlwm zoo. Ntau dhau kev sib tsoo ntawm kev sib tsoo thaum tshav kub kub tsis tsuas yog kev puas ntsoog lub log, tab sis kuj muaj kev sib tsoo ntawm qhov tseeb, cov khoom lag luam zoo nkauj, thiab cov khoom siv mechanies ntawm cov workpiece. Yog li, nkag siab qhov kev cuam tshuam, ua rau, thiab sib txuas daws cov cua sov yog qhov tseem ceeb rau kev txhim kho machining efficiency thiab khoom zoo.
1, tus yam ntxwv ntawm kev sib tsoo cua sov
Kev sib tsoo cov cua sov no yog hais txog cov cua sov tsim rau ntawm qhov chaw sib cuag ntawm qhov kev sib tsoo thaum lub kauj sib tsoo vim kev sib txhuam vim kev sib txhuam thiab shear rog. Sib tsoo cov tshav kub tsis tsuas yog cuam tshuam cov kev sib tsoo, tab sis kuj tseem ua haujlwm ua haujlwm, thiab txawm yuav muaj cov kev mob tshwm sim rau tag nrho cov txheej txheem machining.
Qhov cuam tshuam rau kev sib tsoo log:
Sib tsoo cov nplej passivation: kev sib tsoo ntau dhau yuav ua kom nrawm nrawm nrawm nrawm, txo lawv cov kev sib tsoo, thiab yog li txo qhov kev sib tsoo ntawm lub log sib tsoo.
Sib tsoo log log: Thaum ntau ntau cov cua sov ntxiv, khib nyiab los ntawm cov khoom sib tsoo, ua rau txhaws thiab txo qis kev ua tau zoo thiab ua tau zoo.
Qhov cuam tshuam rau kev ua haujlwm:
Nto hlawv: sib tsoo cua sov ua rau qhov kub ntawm qhov chaw ua haujlwm lossis cov kev hloov pauv xim ntau dua, cuam tshuam rau cov tsos ntawm lub zog thiab kev ua haujlwm ntawm lub workpiece.
Kev txo cov hardting nyuaj: lub caij nyoog kub siab tuaj yeem ua rau muaj kev kub siab tau tuaj yeem ua rau muaj kev kub ntxhov, ua rau cov kev txo qis thiab ua rau lub neej ua haujlwm tsis kam thiab ua haujlwm.
Thermal deformation: Vim tias tsis sib luag ntawm tshav kub hauv qhov chaw ua haujlwm, nws yuav ua rau thermal nthuav lossis deformation ntawm workpiece, uas ua rau txo qis hauv kev txo hauv kev ua haujlwm.
Qhov cuam tshuam rau kev ua:
Nce sib tsoo sib tsoo: kev kub ntxhov tuaj yeem ua kom muaj zog ntxiv rau hauv cov chaw sib tsoo, uas ua kom nce ntxiv kev siv hluav taws xob thiab cuam tshuam rau kev siv tes ua haujlwm.
Kev ua cov khoom ruaj khov: kev sib tsoo cua sov tuaj yeem cuam tshuam rau kev ruaj ntseg ntawm tag nrho cov txheej txheem ua, thiab txawm tias ua rau muaj cov khoom siv ntau zuj zus thiab kua muag.
2, Vim li cas rau kev sib tsoo cov cua sov
Muaj ntau qhov laj thawj rau tiam ntawm kev sib tsoo cua sov, uas yog ze ze rau machining cov yam ntxwv, cov khoom siv log, thiab cov xwm txheej txias.
Kev sib tsoo ntau dhau: txawm hais tias kev sib tsoo nrawm dua tuaj yeem txhim kho kev txuag nyiaj, nws kuj tuaj yeem ua rau kev sib txhuam, ua rau kev sib txhuam ntawm cov nyiaj kub loj. Qhov kev kub siab ntau dhau yuav ua rau muaj kev kub ntxhov sai sai ntawm qhov kub ntawm qhov sib sib sib tsoo ntawm lub log sib tsoo thiab lub workpiece, uas ua rau cov cua sov.
Kev haus cawv ntau dhau thiab txiav qhov tob: Kev txiav ntau dhau thiab kev sib tsoo, yog li nce kev sib tsoo ntawm thaj chaw sib tsoo, ua rau muaj kev sib tsoo hauv tshav kub.
Sib tsoo lub log hnav lossis thaiv: passivation: passivation ntawm abrasive nplej tuaj yeem txo kev sib tsoo ntawm cov kev sib tsoo ntawm cov log sib tsoo, thiab ua rau muaj kev sib tsoo hauv qhov kub thiab txias hauv thaj chaw sib tsoo. Tsis tas li ntawd, txhaws cov log sib tsoo tsis tuaj yeem ua rau cov khib nyiab tshem tawm, ntxiv rau cov cua sov ntxiv.
Lub cua txias tsis txaus: Thaum lub sijhawm sib tsoo, yog tias cov khoom sib tsoo yog qhov tsis txaus thiab tsis txaus siv cua sov, qhov kub nyob hauv thaj chaw sib tsoo yuav nce ntau, ua kom cov cua sov sib tsoo.
Tsawg thermal conductivity ntawm cov ntaub ntawv: thaum lub thermal conductivity ntawm cov txheej txheem workpiece cov ntaub ntawv yog tsawg, kub tsis tau diffuse sai, ua rau muaj kev kub ntxhov hauv ib cheeb tsam. Hauv qhov no, cua sov tau yooj yim concentrated nyob rau hauv thaj chaw sib tsoo, ua rau hlawv lossis thermal deformation.
3, Kev daws rau kev sib tsoo cua sov
Siv cov kev daws teeb meem los daws cov teeb meem ntawm cov cua sov tuaj yeem tswj tau cov kev sib txuam ntawm cov cua sov thiab txhim kho machining zoo.
Xaiv Kev Sib Tsoo Sib Tsoo: Xaiv cov kev sib tsoo cov log tsheb sib tsoo thiab xaiv cov yam ntxwv sib tsoo ntawm cov neeg ua haujlwm ua haujlwm, yog li lawv tsim kom muaj cua sov tsawg thaum lub sijhawm sib tsoo. Tsis tu ncua kho cov log sib tsoo kom tiv thaiv clogging thiab passivation, kom ntseeg tau nws lub peev xwm txiav.
Kho cov kev sib tsoo sib tsoo: kom zoo txo kev sib tsoo nrawm, tswj cov nqi pub mov thiab txiav qhov tob tuaj yeem txo cov khoom sib txhuam ntawm cov cua kub. Ib qho ntxiv, siv cov sib sib sib tsoo sib tsoo lossis ntau qhov kev sib tsoo lub teeb tuaj yeem ua tau zoo zam dhau kev ua kom sov ntau dhau.
Txhim kho cov txheej txheem cua txias: txhim kho cov mov ntawm coolant kom ntseeg tau tias nws tuaj yeem zoo npog qhov kev sib tsoo thaj chaw thiab tshem tawm cov cua sov. Txais yuav high-siab txias lossis taw tes tsuag cua txias thev naus laus zis los txhim kho kev ua haujlwm txias. Xaiv cov dej txias uas tsim nyog (xws li dej-raws li cov roj-based txias) rau cov khoom tshwj xeeb tuaj yeem pab txhim kho cov khoom siv kub dissiciency.
Xaiv cov txheej txheem tsim nyog thiab cov khoom siv nrog cov kev sib tsoo tsis zoo, kev sib tsoo tshwj xeeb xws li cov kev sib tsoo ntub dej tuaj yeem siv los txo qhov kev sib tsoo cua sov. Tsis tas li ntawd, kev kho mob ua ntej ntawm kev kho mob ua kom sov) tuaj yeem txhim kho nws cov cua sov tsis kam thiab tseem pab txo cov khoom cuav.
Txhim kho qhov tseeb ntawm kev ua cov khoom siv: Xaiv cov cuab yeej sib tsoo siab dua thiab cov cuab yeej txiav kom txo qis kev sib txhuam thiab cov cua kub thaum ua haujlwm.
tag
Sib tsoo tshav kub kub yog qhov tsis txaus ntseeg nyob rau hauv cov txheej txheem sib tsoo, uas cuam tshuam ncaj qha cuam tshuam rau qhov chaw zoo, qhov tseeb, thiab kev ua haujlwm ntawm lub workpiece. Los ntawm tsim nyog tswj kev sib tsoo ceev, pub tus nqi, xaiv cov txheej txheem sib tsoo, thiab ua cov khoom sib tsoo tsim nyog, thiab ua cov txiaj ntsig tshwj xeeb thiab cov khoom lag luam zoo tuaj yeem hloov kho. Hauv kev sib tsoo yav tom ntej, kev tshawb nrhiav txuas ntxiv thiab kev thov cov txuj ci tshiab ntxiv, ua tiav kev ua haujlwm kub ntau thiab kev ua haujlwm zoo.
