Pob zeb diamond saw hniav/xuas ntsis: siv rau kev txiav thiab khawb cov ntaub ntawv xws li pob zeb, ceramics, iav, thiab lwm yam.
Cov kua sib tsoo pob zeb diamond/cov tshuaj txhuam polishing: siv dav hauv kev ua cov khoom siv high-precision hauv cov khoom siv hluav taws xob, optics, pwm thiab lwm yam lag luam.
Cov khoom siv pob zeb diamond sib xyaw (PCD/PCBN): muab pob zeb diamond nrog hlau lossis ceramic matrix los ua cov khoom siv cuab yeej sib xyaw uas muaj zog thiab tiv taus kev hnav.
Ⅱ. Cov teb thov ntawm pob zeb diamond abrasives
1. Kev ua khoom siv kho tshuab
Cov pob zeb diamond abrasives siv dav hauv kev ua cov duab thiab sib tsoo ntawm cov khoom siv tawv heev, xws li cemented carbide, ceramics, silicon carbide, iav, ferrite, thiab lwm yam. Kev siv cov log sib tsoo pob zeb diamond rau kev ua cov khoom tsis yog tsuas yog txhim kho kev ua haujlwm zoo thiab qhov zoo ntawm qhov chaw xwb, tab sis kuj ua rau lub cuab yeej siv tau ntev dua thiab txo qhov zaus hloov cuab yeej. Nws yog qhov tsim nyog rau kev tsim khoom ntau, kev ua haujlwm tsis siv neeg thiab kev ua haujlwm siab.
2. Kev lag luam hluav taws xob thiab semiconductor
Thaum lub sijhawm ua cov ntaub ntawv xws li silicon wafers, sapphire substrates, silicon carbide chips, optoelectronic iav, thiab lwm yam, cov pob zeb diamond wire saws, cov kua sib tsoo thiab cov tshuaj txhuam polishing yog cov khoom siv tseem ceeb. Cov pob zeb diamond abrasives tuaj yeem ua tiav submicron lossis txawm tias nanometer-level flatness thiab roughness. Lawv siv dav hauv cov txuas tseem ceeb xws li chip dicing, wafer sib tsoo, thiab photomask polishing. Lawv yog ib qho tseem ceeb hauv kev ua kom muaj kev ua tau zoo thiab cov txiaj ntsig zoo ntawm cov khoom siv hluav taws xob.
3. Kev ua haujlwm kho qhov muag
Pob zeb diamond hmoov siv dav hauv kev txhuam cov iav kho qhov muag, laser qhov rais, sapphire lens thiab lwm yam khoom. Nws lub zog txiav zoo heev thiab kev ruaj khov tshuaj lom neeg tuaj yeem txhim kho qhov zoo ntawm kev ua daim iav thiab ua tiav qhov roughness ntawm qhov chaw Ra tsawg dua 10 nm. Nws yog ib qho khoom siv tseem ceeb rau kev ua tiav cov nto du thiab lub teeb ci ntsa iab.
4. Kev tsim kho thiab kev ua pob zeb
Cov hniav txiav pob zeb diamond, cov ntsis laum, cov xov hlau txiav, thiab lwm yam yog siv dav hauv kev ua cov ntaub ntawv tsim kho xws li granite, marble, thiab concrete. Piv nrog cov cuab yeej ib txwm muaj, cov cuab yeej pob zeb diamond zoo dua hauv kev txiav ceev, lub neej ua haujlwm, thiab qhov zoo ntawm kev txiav, thiab tshwj xeeb tshaj yog tsim rau kev ua cov ntaub ntawv tsim kho uas muaj zog thiab ntom ntom.
5. Lub zog tshiab thiab kev tsav dav hlau
Nrog rau kev txhim kho ntawm cov thev naus laus zis tshiab, qhov kev thov rau cov pob zeb diamond abrasives hauv kev ua cov lithium roj teeb ncej, cov diaphragms ceramic, cov khoom siv hluav taws xob, thiab lwm yam tab tom loj hlob sai. Hauv kev lag luam aerospace, cov cuab yeej pob zeb diamond yog siv rau kev ua kom raug ntawm cov khoom kub kawg ntawm lub cav, cov khoom sib xyaw ua ke, thiab lwm yam, uas txhim kho kev ntseeg tau thiab kev ruaj khov ntawm cov khoom.
III. Xaus Lus
Cov pob zeb diamond abrasives, ua ib yam khoom siv tseem ceeb rau kev tsim khoom lag luam niaj hnub no, tau raug siv los ntawm ntau thiab ntau qhov kev ua haujlwm siab dua vim lawv cov khoom zoo heev thiab kev siv tau dav. Yav tom ntej, nrog rau kev nce qib tas mus li ntawm cov ntaub ntawv tshawb fawb thiab kev tsim khoom siv thev naus laus zis, cov pob zeb diamond abrasives yuav txuas ntxiv txhim kho hauv kev coj ua zoo dua, ntse dua thiab zoo rau ib puag ncig, pab kev lag luam tsim khoom siab dua kom txav mus rau qib siab dua.
