Nyob rau hauv niaj hnub grind ntawm ib tug tibneeg hu tauj coob xovxwm khw, ob peb teeb meem yog li ntxhov siab vim tuag galling. Nws yog qhov uas qhia txog - zaj dab neeg ntxhib thaj uas cov hlau los ntawm lub workpiece pib vuam nws tus kheej mus rau koj lub punch los yog tuag nto, ua rau ib qho kev poob sai sai thiab kev cuam tshuam sai rau kev tsim khoom. Thaum lubrication feem ntau yog thawj qhov uas tib neeg tshawb xyuas, galling feem ntau yog tshwm sim los ntawm ntau qhov sib txawv ntawm cov khoom sib txawv. Txhawm rau kom koj cov cuab yeej ua haujlwm ntev dua thiab txo qis qis qis qis, koj yuav tsum tau saib dhau ntawm cov tshuaj tsuag nozzle thiab tshuaj xyuas cov neeg kho tshuab thiab thermal kev sib raug zoo hauv koj cov khoom siv tuag.
Lub Physics ntawm Degradation
Galling tshwm sim thaum muaj kev kub ntxhov thiab kub dhau los ntawm kev tiv thaiv ciam teb ntawm koj cov roj nplua nyeem, ua rau microscopic metallic bonds tsim ntawm lub cuab yeej thiab cov ntawv hlau. Thaum daim ntawv cog lus no pib, nws snowballs; lub thaj ua haujlwm ntxhib ua zoo li tus scraper, rub cov khoom siv ntau dua ntawm cov khoom ua haujlwm tom ntej thiab ua rau qhov tsis zoo ntawm txhua qhov mob stroke. Yog tias koj pom cov qauv no pib, tsis txhob cia cov roj ntws nce ntxiv - tshuaj xyuas koj qhov kev tshem tawm. Yog tias qhov tuag-rau- qhov sib txawv ntawm qhov sib txawv yog nruj heev, koj yeej tseem ceeb nce qhov kev sib txhuam siab tshaj qhov uas cov qauv roj nplua nyeem tuaj yeem ua tau. Qee lub sij hawm, qhov kev tshem tawm me ntsis, txawm tias tsuas yog ob peb microns, tuaj yeem muab qhov chaw xav tau rau cov roj nplua nyeem los tuav nws cov yeeb yaj kiab thiab tiv thaiv "hlau-rau-hlau" kev sib cuag uas ua rau muaj kev kub ntxhov.
Surface Texture: Vim li cas "Smoother" tsis zoo dua
Muaj ib qho kev xav tsis zoo uas daim iav - polishing tiav yog qhov kev tiv thaiv zoo tshaj plaws tiv thaiv galling. Nyob rau hauv qhov tseeb, ib qho ultra- zoo nto tej zaum yuav tsim tau ib qho "txhim kho" qhov twg cov roj nplua nyeem yog wiped tag nrho, tsis muaj cushion ntawm cov hlau nto. Ntau tus neeg tsim khoom siv lub caij nyoog nyiam qhov ua tib zoo qhia kev sib tsoo- feem ntau hu ua "honed" lossis "av" tiav- uas ua raws li cov kev taw qhia ntawm cov hlau ntws. Cov grooves microscopic no ua raws li cov dej me me uas tuav mus rau cov roj nplua nyeem, ua kom nws nyob rau hauv qhov chaw tsim txawm tias nyob rau hauv lub siab loj ntawm cov xovxwm. Yog tias koj cov punches tsis tu ncua khaws cov khoom, sim sim nrog qhov sib txawv ntawm qhov sib txawv - cov txheej txheem ua kom tiav kom pom qhov twg khaws cov kua dej nyob qhov twg nws yuav tsum tau ua.
Txheeb xyuas qhov kub thiab txias
Galling feem ntau khi rau hauv cheeb tsam kub. Yog tias koj tab tom tsim cov khoom nrog cov khoov nyuaj lossis sib sib zog nqus-kos ntu, cov hlau hauv cov cheeb tsam ntawd raug kev ntxhov siab loj, uas ua rau muaj cua sov loj. Yog tias koj cov khoom siv tuag tau nqus cov cua sov no tab sis tsis muaj txoj hauv kev kom dissipate nws, qhov kub thiab txias ntawm qhov sib cuam tshuam yuav dhau mus rau qhov pib qhov twg koj cov kua nplaum tawg. Tshawb xyuas koj tus qauv tsim khau tuag: Puas muaj qhov chaw uas cov khoom siv tau zoo "raug" yam tsis muaj kev sib cuag rau lub hauv paus phaj? Txhim kho cov thermal conductivity-tej zaum los ntawm kev siv bronze coj daim hlau los yog ntxiv cov cua txias hauv zos- tuaj yeem pab tshem tawm cov cua sov ntawm qhov chaw ua haujlwm, ua kom koj cov roj nplua nyeem siv tau ntev dua thiab tiv thaiv qhov pib ntawm kev puas tsuaj.
Kev ntsuas cov khoom hardness thiab txheej
Qee zaum, qhov teeb meem tsis yog lub cuab yeej - nws yog qhov tsis sib xws ntawm cov khoom siv thiab cov khoom ua haujlwm. Yog tias koj niaj hnub tsim siab - lub zog steels, tus qauv D2 cuab yeej steel yuav tsis txaus. Kev hloov pauv mus rau qib siab PVD (Lub Cev Vapor Deposition) txheej txheej feem ntau yog tus nqi ntau tshaj - txoj hauv kev zoo kom tsis txhob ua rau tuag hauv nws txoj kev. Cov txheej txheej zoo li Chromium Nitride lossis tshwj xeeb DLC (Pob zeb diamond-Zoo li Carbon) muab cov tshuaj tiv thaiv tsis zoo uas tsuas yog tsis kam koom nrog cov ntawv hlau. Yog tias koj pom koj pab neeg saib xyuas tas li buffing thiab kho tib lub punch, kev hloov kho PVD txheej yuav yog txoj hauv kev ceev tshaj plaws kom tshem tawm qhov teeb meem.
Tsim kom muaj Diagnostic Culture
Cov khw muag khoom zoo tshaj plaws tsis yog kho galling xwb; lawv ua ntaub ntawv. Yog tias ib qho cuab yeej tshwj xeeb yuav ua rau qhov adhesion, khaws cov ntaub ntawv: xovxwm ceev yog dab tsi? Puas muaj kev hloov pauv ntawm cov khoom siv lossis cov coil batch? Puas yog lub khw kub siab dua li niaj zaus? Los ntawm kev kho txhua qhov kev tshwm sim galling raws li cov ntaub ntawv taw qhia, koj tuaj yeem txheeb xyuas cov qauv uas ua rau muaj kev txhim kho. Thaum koj tuaj yeem taug kev mus rau hauv lub rooj sib tham nrog tus neeg siv khoom thiab piav qhia raws nraim li cas koj tau txhim kho koj cov txheej txheem tsim kom tshem tawm qhov tsis xws luag, koj tsis yog tus neeg xa khoom xwb -koj yog ib tus neeg koom tes uas nkag siab txog "science" hauv pem teb. Cov theem ntawm kev ua haujlwm pom tseeb yog raws nraim qhov kev yuav khoom thoob ntiaj teb ua rau nrhiav thaum lawv tau soj ntsuam lawv qhov ntev - cov saw hlau xa khoom.
