Kev sib tham txog qhov kev sib cav ntawm titanium alloys
Aug 13, 2025
Vim yog titanium alloy qhov kev tawm tsam qis, kev ua haujlwm hnyav, thiab kev ua haujlwm siab rau hnav thiab chipping thaum lub tshuab machining, ua kom zoo nyuaj rau kev tuaj yeem lav. Yog li, yuav ua li cas thiaj txiav yuav txiav txim? Thaum txiav titanium alloys, txiav cov rog yog cov qes, ua haujlwm tawv, thiab lub ntsej muag zoo tiav tau yooj yim. Txawm li cas los xij, titanium alloys muaj tsawg thermal conductivity thiab siab txiav cov khoom siv kub, ua rau cov cuab yeej tseem ceeb thiab cov cuab yeej tsis muaj txiaj ntsig. Tungsten - Cobalt carbide cov cuab yeej, xws li lawv muaj tsawg zog condanitivity, siab zog, thiab cov noob me me. Nti tawg yog kev sib tw nyob rau hauv tig titanium alloys, tshwj xeeb tshaj yog thaum machining titanium. Yuav kom ua tiav chip tawg, qhov txiav ntug tuaj yeem ua av rau hauv ib qho kev nyab xeeb scc tab sis puab nyob rau sab nraum qab, nqaim nyob rau sab nraum qab thiab thoob plaws nraub qaum. Qhov no pab tau nti nti thiab tiv thaiv cov chips ntawm entanglement thiab khawb lub workpiece nto.
Titanium alloy txiav muaj qhov tsis txaus ntseeg coefficient, ib qho khoom siv me me}}}}}}}} kub. Txhawm rau txo cov kev txiav kub tiam, lub rake lub kaum sab xis ntawm tig lub cuab yeej yuav tsum tsis loj dhau. Carbide tig cov cuab yeej feem ntau muaj lub kaum sab xis ntawm 5 - 8 degrees. Vim yog lub siab tawv ntawm titanium alloy, sab nraub qaum yuav tsum tau khaws cia rau 5 degrees kom nce cov cuab yeej cov kev cuam tshuam. Txhawm rau txhim kho cov cuab yeej taub lub zog, txhim kho cua sov dissipation, thiab txhim kho lub cuab yeej cov kev cuam tshuam kuj, lub tog raj tsis zoo ntawm lub kaum sab xis yog siv. Kev tswj cov kev txiav ceev ceev (tsis yog siab dhau), thiab siv cov kua dej tsis zoo, thaum tseem xaiv tus nqi ua kom tsim nyog, yog qhov tseem ceeb.
Drilling tseem yog ib txoj haujlwm ib txwm muaj, tab sis titanium alloy drilling tuaj yeem nyuaj, nrog cov cuab yeej hlawv thiab tawg kis. The main causes are poor drill sharpening, inadequate chip removal, poor cooling, and poor process system rigidity. Ua raws li cov taub tawv laum, txoj kab chisel yuav tsum tau nqaim, feem ntau nyob ib ncig ntawm 0.5 mm, txhawm rau txo cov axial rog thiab kev co los ntawm kev tiv thaiv. Nyob rau tib lub sijhawm, cov laum tawm thaj av yuav tsum tau nqaim 5 {{}}}}} mm los ntawm kwv yees li 0.5 mm los pab txhawb cov nti tawm. Lub laum me ntsis lub geometry yuav tsum tau ua kom raug, thiab ob qho tib nplais yuav tsum yog ib qho zoo. Qhov no tiv thaiv laum me ntsis los txiav ntawm tsuas yog ib sab, feeb rau kev txiav kev txiav ntawm ib sab thiab ua rau lub cev ua ntej hnav thiab txawm chipping vim yog swb. Yeej ib txwm tuav lub ntsej muag ntse. Thaum lub ntug yuav ua rau npub, nres tsis tas li drilling tam sim ntawd thiab resharpen lub laum. Txuas ntxiv txhawm rau txiav tawm nrog lub duas laum me ntsis yuav hlawv sai thiab anneal vim kub qhuav, rendering nws piam. Qhov no tseem ua tuab tuab cov tawv tawv ntawm qhov chaw ua haujlwm, ua kom rov qab rov- drilling ntau nyuaj thiab xav tau ntau resharpening. Ua raws li qhov yuav tsum tau txav chaw txiav txim siab, lub laum yuav tsum tau txo qis thiab cov tub ntxhais tuab tau nce siab thiab tiv thaiv kev co thaum lub sijhawm khiav haujlwm. Kev xyaum tau qhia tias A IG15 Laum me ntsis nrog ib qho 150 hli inch muaj lub neej ntev dua li ib nrog 195 hli txoj kab uas hla. Yog li ntawd, xaiv txoj cai ntev yog qhov tseem ceeb heev. Kev txiav txim los ntawm ob txoj kev siv cov qauv uas tau hais los saud, titanium alloy machining yog qhov nyuaj. Txawm li cas los xij, nrog kev ua tib zoo ua, zoo precision seem tuaj yeem tsim, xws li titanium alloy qhov chaw rau aerospace khoom.
Precision Machining nyob rau hauv Aerospace kev lag luam qhov kev xav tau siab ntawm cov ntaub ntawv. Qhov no yog ib nrab vim yog qhov tshwj xeeb uas xav tau ntawm cov khoom siv aviation, tab sis tseem ceeb tshaj, nws yog cuam tshuam los ntawm Aerospace ib puag ncig. Vim hais tias ntawm cov kev sib txawv ntawm ib puag ncig ib puag ncig, cov qauv lag luam muaj tsis tau raws li cov cai no, tsim nyog siv cov kev xaiv tshwj xeeb. Niaj hnub no, peb yuav qhia cov khoom siv sib xws: titanium alloy, tshwj xeeb yog ib txwm muaj nyob rau hauv aerospace. Vim li cas cov khoom no thiaj li siv dav? Qhov laj thawj cuam tshuam nrog nws cov khoom. Titanium alloy muaj qhov tsis tshua muaj lub ntiajteb txawj nqus, ua rau muaj qhov tsawg. Nws lub zog siab thiab thermal lub zog pab rau nws lub hardness, siab} kev tawm tsam dej hiav txwv, acid thiab alkali corrosion, ua rau nws haum rau kev siv nyob rau ib puag ncig. Tsis tas li ntawd, nws qhov kev deformation tsawg tau coj mus rau nws cov ntawv thov thoob plaws hauv kev lag luam xws li kev lag luam xws li aerospace, nkoj, thiab roj ntsha, thiab tshuaj lom neeg ua lag luam. Vim tias titanium alloy muaj qhov sib txawv saum toj no los ntawm cov ntaub ntawv dog dig, nws tseem nyuaj ua rau lawv muaj qhov tseeb. Ntau lub tshuab machining yog tsis kam ua cov ntaub ntawv no thiab tsis paub yuav ua li cas cov txheej txheem cov khoom no.
