Sib tsoo log hnav txoj kev

Nyob rau hauv cov ntaub ntawv ntawm kev tsim, cov cuab yeej abrasive feem ntau hu ua "cov hniav ntawm kev lag luam," ua lub luag haujlwm tseem ceeb hauv kev nce qib ntawm kev tsim khoom lag luam thiab ua lub luag haujlwm tseem ceeb rau kev loj hlob ntawm cov tswv yim, kev lag luam tawm tshiab xws li kev tsim khoom siv tshuab siab heev. . Lub superabrasive sib tsoo log, crafted nrog pob zeb diamond los yog cubic boron nitride (CBN) raws li cov khoom siv abrasive, yog ib hom kev ruaj khov abrasive uas yog tus cwj pwm los ntawm nws cov efficiency, precision, thiab durability. Nws muaj peev xwm ua tau zoo ntawm kev ua haujlwm siab, ua haujlwm tau zoo, thiab ultra-ntxuav machining ntawm ntau yam khoom siv nyuaj rau lub tshuab uas xav tau ntau zuj zus thiab nyuaj rau cov pa abrasive log los tuav. Raws li qhov tshwm sim, kev hloov pauv ntawm "D (pob zeb diamond) hloov C (silicon carbide), thiab B (CBN) hloov A (alumina)" tsis tu ncua yog qhov tseem ceeb hauv kev hloov pauv ntawm kev sib tsoo tshuab.

Txawm hais tias qhov tshwj xeeb hardness thiab lub zog ntawm superabrasive sib tsoo lub log, lawv qhov chaw tseem tuaj yeem hnav lossis raug thaiv thaum lub sijhawm machining. Qhov no ua rau muaj kev sib tsoo quab yuam thiab nce qhov kub thiab txias, uas tuaj yeem ua rau kev sib tsoo vibrations thiab thermal puas, yog li cuam tshuam qhov zoo ntawm lub workpiece. Tsis tas li ntawd, qhov hnav ntawm qhov sib tsoo lub log tuaj yeem poob nws cov duab geometric zoo, uas ua rau txo qis qhov tseeb ntawm qhov chaw ua haujlwm.

Tam sim no, cov tswv yim rau kev hnav khaub ncaws superabrasive sib tsoo log tuaj yeem muab faib ua peb pawg loj: thawj pab pawg koom nrog cov txheej txheem kev siv tshuab xws li kev hnav khaub ncaws abrasive, kev hnav khaub ncaws sib npaug, thiab khob lub log hnav; pab pawg thib ob suav nrog kev hnav khaub ncaws tshwj xeeb xws li kev hnav khaub ncaws hluav taws xob, electrolytic hauv txheej txheem hnav khaub ncaws, thiab hnav khaub ncaws laser; pawg thib peb muaj feem xyuam rau kev sib xyaw ua ke uas sib xyaw ua ke ntau cov txuj ci tseeb los txhim kho ib leeg, suav nrog kev siv tshuab-laser ua ke, kev siv tshuab-tshuaj lom neeg ua ke, thiab kev hnav khaub ncaws ultrasonic.

Cov txheej txheem hnav khaub ncaws no raug ntsuas raws li lawv cov kev hnav khaub ncaws zoo, qhov zoo, qhov tseeb, cov nqi ua haujlwm, kev cuam tshuam ib puag ncig, daim ntawv thov kev lag luam tam sim no, thiab muaj peev xwm txhim kho. Qhov kev sib piv no yog tsim los muab kev nkag siab rau kev xaiv cov txheej txheem superabrasive log uas tsim nyog thiab qhia txog kev nce qib ntawm cov thev naus laus zis tshiab thiab kev tshawb fawb yav tom ntej.
