PCD: Qhov Kev Xaiv Zoo Tshaj Plaws rau Kev Siv Tshuab Aluminium Workpieces
Cov cuab yeej Polycrystalline Diamond (PCD) muaj cov txiaj ntsig zoo rau kev ua cov khoom siv txhuas, suav nrog lub neej ntev ntawm cov cuab yeej thiab cov nqi tshem tawm hlau siab. Txawm li cas los xij, lawv cov nqi pib tuaj yeem siab dua, uas yuav ua rau cov nqi ua tiav ntau ntxiv. Cov ntaub ntawv txhuas niaj hnub no tau hloov pauv ntau heev, thiab thaum ua ntau yam khoom siv txhuas tshiab tsim - tshwj xeeb tshaj yog cov ntaub ntawv sib xyaw ua ke siab-silicon - nws yog qhov tseem ceeb kom xaiv cov cuab yeej PCD qib thiab cov qauv geometric kom zoo kom ua tiav kev tsim khoom thiab kev ua haujlwm zoo. Hmoov zoo, vim muaj kev sib tw ua lag luam thiab kev nce qib hauv cov txheej txheem tsim khoom, tus nqi ntawm Cov Cuab Yeej Pcd tau txo qis dua 50%, ua rau lawv yooj yim nkag mus tau.
Cov yam ntxwv tseem ceeb ntawm PCD cov cuab yeej
Cov ntxig PCD sib xyaw yog tsim los ntawm kev sib xyaw pob zeb diamond thiab cov tshuaj catalyst hauv qab qhov kub thiab siab, ua rau muaj cov qauv tshwj xeeb nrog kev sib txuas "choj" ntawm cov pob zeb diamond. Cov txheej txheem no tsim cov qauv kob catalyst, zoo ib yam li cov khoom siv pob zeb diamond monolithic. Tsis zoo li PCBN (Polycrystalline Cubic Boron Nitride), uas tsis muaj cov khoom sib txuas tiag tiag ntawm cov khoom CBN, PCD muaj cov qauv coalescent qhov twg cov pob zeb diamond sib txuas los ntawm cov choj lattice.
Cov qib cuab yeej PCD raug faib ua pawg raws li qhov loj ntawm cov pob zeb diamond me me. Raws li cov qauv kev lag luam, cov qib PCD zoo, nruab nrab, thiab ntxhib sib raug rau qhov kwv yees li ntawm 2 μm, 10 μm, thiab 25 μm, raws li. Cov qib PCD ntxhib qhia tau tias muaj zog dua thiab tiv taus kev hnav, muab lub neej cuab yeej ntev dua thaum lub sijhawm ua haujlwm ntxhib. Txawm li cas los xij, cov npoo txiav ntawm cov cuab yeej PCD ntxhib yuav tsis ua tiav qhov chaw du uas ua tau nrog cov cuab yeej PCD zoo, uas, thaum muab qhov zoo ntawm qhov chaw, feem ntau hnav tawm sai dua.
Cov Cuab Yeej Txiav Pcd zoo tagnrho rau cov ntawv thov xws li cov hniav pom pob zeb diamond, kev tsim kho coring thiab drilling, ntug-trimming pob zeb diamond cutters, tig thiab milling inserts, thiab pob zeb diamond drill bits rau qhov-drilling hauv cov ntaub ntawv composite thiab circuit boards.
Boreas tsim cov cuab yeej PCD uas nto moo rau lawv cov khoom zoo tshaj plaws thiab ntau yam kev siv, thaum tswj hwm tus nqi sib tw. Yog tias koj xav txhim kho koj cov peev xwm ua haujlwm, Boreas yog koj qhov kev xaiv zoo tshaj plaws rau cov cuab yeej PCD zoo uas xa cov kev ua tau zoo thiab tus nqi.
