Vim tias nws muaj kev nyuaj siab thiab cov hnav muaj zog tsis kam, cov carbide yog dav siv hauv kev lag luam thiab yog paub tias yog cov hniav. Txawm li cas los xij, cemented carbide cov khoom yog tseem pheej siv rau khoov thiab deformation thaum lub sijhawm ua. Niaj hnub no, peb yuav soj ntsuam cov laj thawj ntawm kev khoov ntawm cov tshuaj pleev cov kev ntsuas carbide, thiab tshawb xyuas cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab tshawb xyuas cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab tshawb xyuas cov kev ntsuas carbide, thiab tshawb xyuas cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab tshawb xyuas cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab tshawb xyuas cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab tshawb xyuas cov kev ntsuas carbide, thiab nrhiav cov kev ntsuas carbide, thiab tshawb xyuas cov kev ntsuas carbide, thiab tshawb xyuas cov kev ntsuas uas tuaj yeem tiv thaiv los ntawm deformation ntawm qhov chaw.
Cov khoom lag luam carbide yog ib hom tungsten carbide li cov khoom siv sib tsoo, raws li cov khoom siv sib tsoo, raws li kev siv hluav taws xob, cov ntawv cua, discs, discs, puag ncig cov kab, strips lossis moulded rau hauv cov kev sib txawv ntawm kev ua kom zoo nkauj ntawm carbide.
Muaj ntau cov laj thawj uas cuam tshuam rau kev deformation thiab dabtsi yog tsim nyog los tshuaj xyuas cov khoom siv carbide tshwj xeeb, uas tej zaum yuav tshwm sim los ntawm ib qho kev sib xyaw lossis kev sib xyaw ua ke. Cov laj thawj tseem ceeb yog: Carralt gradient, ntom kev thauj khoom, shrinkage coefficient, thiab lwm yam.
Nyob rau hauv lub tshuab dhos machining, nws feem ntau yog siv centripetal for siv peb-puab tsaig lossis plaub-puab tsaig chuck ntawm lub tshuab dhos kom tshuab dhos ua tshuab dhos ua tshuab dhos, thiab tom qab ntawd cov txheej txheem. Nyob rau hauv txoj kev no, nws yog ib qho yooj yim kom ua rau kev hloov pauv hloov pauv ntawm qhov raug ua raws li kev ua ntawm lub zog.
Nws yog ib qho yooj yim los deform tom qab kev kho cua sov.
Rau cov ntawv nyias nyias siv, vim lawv qhov ntev ntev thiab lub taub, lawv feem ntau khoov tom qab kev kho cua sov. Tej zaum yuav muaj kev sib cav sib ceg nyob hauv nruab nrab, lub dav hlau sib txawv nce, thiab ntawm qhov kev cuam tshuam ntawm ntau yam sab nraud, feem yog khoov.
Kuj tseem muaj kev ywj pheej ntawm txoj kev quab yuam sab nraud
Thaum ua tiav tungsten carbide machining, muaj ntau cov laj thawj rau txoj kev deormation ntawm qhov chaw. Ua ntej, yog tias tus qauv sab hauv ntawm qee qhov muaj cov ntawv nyias nyias, nws tsis tuaj yeem sib haum rau cov kev ua haujlwm, uas yog qhov yooj yim los ua rau lub cim ntawm kev tawm tsam ywj. Qhov thib ob yog qhov tsis sib xws ntawm cov tshuab dhos thiab fixsture, yog li ntawd lub zog ntawm ob tog yog qhov tsis sib xws, ua rau ib feem nrog me ntsis quab yuam thaum txiav txim siab. Thib peb, txoj haujlwm ntawm cov seem hauv kev ua cov txheej txheem ua haujlwm tsis yog, kom cov rigidity thiab lub zog ntawm cov feem raug txo. Plaub, muaj lub zog txiav kuj tseem yog ib qho ntawm cov laj thawj rau txoj kev deformastic ntawm qhov chaw.
Cov no yog txhua yam uas ua rau khoov thiab deformation ntawm cemented carbide khoom. Peb yuav tsum them nyiaj ntau dua hauv cov txheej txheem ua, thaum muaj kev pov tseg, tsis tau rov qab siv cov nqi, tus yuam sij tsuas yog rov qab rov ua dua, ncua tus qhua tuaj noj mov.
