Kev ua tau zoo ntawm Ceramic Alumina Abrasive Particles tuaj yeem txhim kho los ntawm kev ntxiv ib nrab nkig molten alumina los ua cov log sib xyaw. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog yuav tsum paub txog qhov ntev ntawm qhov sib tsoo lub log ntawm lub workpiece, thiaj li txiav txim siab qhov sib tsoo log feem. Silicon carbide: SiC abrasive muaj lub ntsej muag ntse. Haum rausib tsoocov ntaub ntawv nyuaj (xws li cemented carbide). Vim nws cov ntse ntse, nws kuj tsim nyog rau kev ua cov ntaub ntawv mos heev, xws li txhuas, polymers, roj hmab, tsis muaj zog hlau, tooj liab alloys thiab yas.
Pob zeb diamond: Ob lub pob zeb ntuj thiab hluavtaws tuaj yeem siv rau kev sib tsoo. Pob zeb diamond yog ultra-siab hardness daim ntawv ntawm carbon. Vim nws muaj affinity rau hlau (steel yog ib tug alloy ntawm hlau thiab carbon) thiab cov ntaub ntawv ceev ceev, nws tsis haum rautshuabferrous cov ntaub ntawv, tab sis pob zeb diamond yog tshwj xeeb tshaj yog haum rau kev sib tsoo cov ntaub ntawv uas tsis yog-ferrous, titanium, ceramics thiab cermets. CBN: Zoo li pob zeb diamond, CBN yog ib qho khoom kim heev.
Tus nqi ntawm lub log abrasive nyuaj yog ntau tshaj 50 lub sij hawm siab dua li ntawm lub log abrasive, tab sis nws lub neej kev pab yog ntau tshaj 100 lub sij hawm siab dua li ntawm lub log abrasive. Txawm hais tias cov hlau hnyav tshaj plaws hauv av, nws tsuas yog hnav me ntsis. CBN feem ntau haum rautshuabgferrous cov ntaub ntawv, tshwj xeeb tshaj yog thaum cov duab ntawm kev sib tsoo log yuav tsum tau khaws cia rau lub sij hawm ntev, xws li kev sib tsoo ntawm raceway nyob rau hauv cov kabmob. Tsis tas li ntawd, CBN yog qhov tsim nyog rau cov txheej txheem ntawm kev hloov lub log tsis tu ncua, vim tias cov khoom siv me me thiab hloov lub log yuav tsum hnav khaub ncaws thaum lub sijhawm teeb tsa, uas yog qhov tseem ceeb ua rau kev siv lub log.
Vim tias CBN yuav hnov mob nrog dej ntawm qhov kub thiab txias, yuav tsum siv ethylene glycol lossis roj. Daim ntawv cog lus ntawm dog digsib tsoolog tuaj yeem yog ceramic, resin lossis yas, thaum daim ntawv cog lus ntawm super nyuaj abrasive tuaj yeem them rau ntawm lub log sib tsoo los ntawm sintered hlau matrix lossis electroplating npib tsib xee txheej. Hom kev sib tsoo no yog impermeable thiab tsis muaj kab noj hniav.
Covsib tsooCov kua dej ntawm cov hlau nplaum thiab electroplated sib tsoo lub log yuav tsum tau ua tib zoo xaiv kom tsis txhob sib tsoo lub log los ntawm kev swb. Qhov loj loj dynamic hydraulic siab generated ntawm txiav arc thaum lub sij hawm slipping yuav nqa lub sib tsoo log, ua rau deterioration ntawm workpiece tiav thiab acceleration ntawm sib tsoo log hnav.
