Kev txhim kho thiab txhim kho cov khoom siv cuab yeej yog qhov tseem ceeb heev rau kev tsim cov txheej txheem hlau. Cov cuab yeej zoo tuaj yeem ua haujlwm tau zoo thiab ua tiav sai sai, thiab tuaj yeem tswj tau lub neej zoo. Hauv kev tsim khoom, feem ntau siv cov cuab yeej tig cov khoom siv feem ntau suav nrog cov hauv qab no:
1. High carbon steel
High carbon steel tig cov cuab yeej siv carbon steel nrog cov ntsiab lus carbon ntawm 0.8 feem pua thiab 1.5 feem pua. Cov pa roj carbon steel zoo li no yog hardened tom qab quenching. Vim tias qhov kev sib txhuam ntawm kev txiav yog ib qho yooj yim los ua tempering softening, nws yog hloov los ntawm lwm yam cuab yeej xws li high-speed steel. Nws yog feem ntau haum rau txiav cov ntaub ntawv mos hlau.
2. Kev kub ceev hlau
Raws li cov hlau-raws li alloy, high-speed steel, tseem hu ua dawb tig cov cuab yeej, muaj cov ntsiab lus carbon ntawm 0.7-0.85 feem pua , thiab cov ntsiab lus alloy xws li w thiab Cr ntxiv rau carbon hlau. Piv txwv li, cov khoom siv high-speed steel muaj 18 feem pua tungsten, 4 feem pua chromium thiab 4 feem pua vanadium. Thaum tshav kub kub ntawm high-speed steel tig cuab yeej ua los ntawm cov khoom no yuav siab li 6000 degree thaum sib txhuam. Haum rau xov tig ntawm 1000rpm.
3. Tsis yog cam khwb cia hlau alloy cuab yeej
Qhov no yog ib qho alloy ntawm cobalt, chromium thiab tungsten, uas muaj qee qhov teeb meem hauv kev txiav. Nws yog tsim los ntawm casting, yog li nws tseem hu ua superhard cam khwb cia hlau. Cov cuab yeej zoo li no muaj siab toughness thiab hnav tsis kam. Feem ntau, qhov hardness yuav tsis cuam tshuam rau qhov kub ntawm 8200 degree, thiab nws cov cua kub tsis kam yog siab dua li ntawm high-speed steel. Nws yog tsim rau high-speed thiab tob txiav.
4. Sintered carbide cuab tam
Carbide tej cuab yeej yog hmoov metallurgy khoom. Cov khoom tseem ceeb ntawm tungsten carbide txiav cov cuab yeej yog 50 feem pua - 90 feem pua tungsten, nyob rau hauv uas titanium, molybdenum, tantalum thiab lwm yam hmoov ntxiv ua binders, thiab tom qab ntawd ua tiav los ntawm cua sov thiab sintering. Piv nrog rau lwm cov ntaub ntawv, lub hardness ntawm cov cuab yeej no yog siab dua, uas yog peb zaug ntawm hardest high carbon steel. Nws yog qhov tsim nyog rau kev txiav cov hlau lossis pob zeb.
5 ceramic tig cuab tam
Ceramic tig cov cuab yeej yog ua los ntawm alumina hmoov, nrog ib qho me me ntawm cov ntsiab lus ntxiv, thiab sintered ntawm qhov kub thiab txias. Nws yog siab tshaj tungsten carbide nyob rau hauv hardness, kub kuj thiab txiav ceev. Txawm li cas los xij, vim nws qhov kev ntxhib los mos, tsis tu ncua lossis hnyav tig tsis tuaj yeem nqa tawm, thiab nws tsuas yog tsim nyog rau high-speed precision txiav.
6 pob zeb diamond cutter
Thaum cov khoom siv no yog siv rau kev ua tiav saum npoo, nws tuaj yeem polished nrog puag ncig lossis muaj pob zeb diamond nrog cov npoo npoo. Cov neeg siv khoom tuaj yeem tau txais qhov smoother nto. Cov neeg siv tuaj yeem ua precision tig ntawm tooj liab alloy lossis lub teeb alloy. Thaum tig, siv kev kub ceev, tsawg kawg yog 60-100m / min.
7 boron oxide ua
Cubic boron oxide yog cov khoom siv nrov hauv xyoo tas los no. Nws hardness thiab hnav tsis kam yog thib ob tsuas yog pob zeb diamond. Cov cuab yeej no yog tsim rau kev ua cov silhouette thiab hnav-resistant ferrous alloys.
