Txiav discs yog ib qho ntawm cov cuab yeej tseem ceeb tshaj plaws rau cov neeg ua haujlwm nrog hlau. Lawv yog siv los txiav cov ntawv hlau, cov kav dej, thiab lwm yam khoom ua los ntawm cov hlau sib txawv. Cutting discs yog me me, ncig cov hniav ua los ntawm cov khoom siv abrasive uas tau muab tso rau ntawm ib lub spindle lossis tuav. Ib qho kev txiav disc feem ntau hu ua 'txiav log' lossis 'lub log txiav tawm'.
Kev siv cov txiav discs yog dav thiab ntau yam. Qee qhov kev siv ntau tshaj plaws suav nrog kev tsim khoom, kev tsim kho, hlau fabrication, thiab kho tsheb. Cov neeg ua haujlwm hlau feem ntau siv cov ntawv txiav los txiav thiab ua cov ntaub ntawv raw hlau rau hauv cov duab tshwj xeeb thiab ntau thiab tsawg rau ntau lub hom phiaj tsim khoom. Cov neeg ua haujlwm tsim kho feem ntau siv cov discs no los txiav cov ntawv hlau thiab cov kav dej kom haum rau hauv qhov chaw ua ntej. Cov kws kho tsheb kho tsheb txiav thiab ua cov hlau hlau los kho cov tsheb puas.
Muaj ntau hom kev txiav discs muaj nyob hauv khw. Cov yam ntxwv thiab txiav peev xwm ntawm txhua lub disc sib txawv raws li nws muaj pes tsawg leeg. Feem ntau, txiav discs yog tsim los ntawm ob hom khoom siv abrasive - ceramic thiab aluminium oxide. Ceramic txiav discs yog tsim rau cov hlau tawv, thaum txhuas oxide txiav discs yog zoo tagnrho rau softer hlau xws li txhuas.
Kev siv cov txiav txiav kom zoo yog qhov tseem ceeb. Cov cuab yeej tiv thaiv xws li hnab looj tes, tsom iav kev nyab xeeb, thiab daim npog ntsej muag yog qhov yuav tsum tau siv thaum siv lub tshuab txiav. Nws tseem yog ib qho tseem ceeb los xyuas cov disc rau cov kab nrib pleb lossis kev puas tsuaj ua ntej txhim kho nws. Ua ntej pib txheej txheem txiav, nws yog ib qho tsim nyog los xyuas kom meej tias lub tshuab ua haujlwm zoo, thiab tag nrho cov kev tiv thaiv kev nyab xeeb yog nyob rau hauv qhov chaw.
Hauv kev xaus, kev siv cov txiav discs tau hloov pauv kev tsim khoom thiab kho kev lag luam. Nws tau ua rau txiav thiab shaping cov ntaub ntawv hlau sai, ua tau zoo, thiab meej. Nrog rau qhov kev xav tau ntawm cov khoom hlau loj zuj zus tuaj, txiav cov discs yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum siv lawv kom nyab xeeb thiab muaj lub luag haujlwm kom tsis txhob muaj xwm txheej lossis kev phom sij.
