Hauv thaj chaw ntawm kev tsim khoom, kev tsim kho, kev tsim hlau, thiab kev kho tsheb, kev txiav cov discs (tseem hu ua cut{0}}tawm lub log) yog cov khoom siv tsis zoo. Engineered rau siab -ceev, precision sib cais cov khoom, cov nyias, ntxiv dag zog lub log ua lub luag hauj lwm tseem ceeb nyob rau hauv shaping lub efficiency thiab zoo ntawm industrial ntau lawm txheej txheem.
Cov kws tshaj lij txiav discs feem ntau yog tsim los ntawm cov nplej abrasive sib koom ua ke los ntawm cov cob, nrog fiberglass mesh reinforcement los txhim kho cov qauv kev ruaj ntseg thiab tiv thaiv kev tawg thaum lub sijhawm ua haujlwm siab -. Kev xaiv ntawm cov nplej abrasive yog tsim los rau cov khoom txiav tshwj xeeb: aluminium oxide (corundum) yog qhov zoo tagnrho rau kev txiav cov pa roj carbon steel, alloy steel, thiab cam khwb cia hlau vim nws zoo heev toughness thiab hnav tsis kam; zirconia alumina muaj kev ua tau zoo tshaj plaws hauv kev txiav cov hlau tsis muaj steel thiab siab - kub alloys, raws li nws nthuav tawm nws tus kheej- cov khoom ntse hauv qab kub; silicon carbide yog qhov zoo dua rau kev txiav cov khoom tsis yog-hlau cov ntaub ntawv xws li pob zeb, pob zeb, thiab iav, ua tsaug rau nws cov hardness siab thiab ntse txiav.
Txiav discs raug cais raws li ntau yam, nrog rau txoj kab uas hla, thickness, thiab daim ntawv thov hom. Feem ntau cov kab uas hla ntawm 4 ntiv tes (100mm) rau lub kaum sab xis ntawm tes rau 24 ntiv tes (600mm) rau cov loj- teev cov tshuab txiav. Thinner discs (0.8-3mm) yog tsim los rau precision txiav ntawm nyias{11}}cov kav dej, cov ntawv, thiab cov ntaub ntawv, txo cov khoom poob thiab xyuas kom huv si. Thicker discs (3-6mm) yog haum rau hnyav- lub luag hauj lwm txiav ntawm tuab steel phaj, tuav, thiab castings, muab kev txhim kho durability thiab load-bearing muaj peev xwm. Tsis tas li ntawd, tshwj xeeb txiav discs muaj rau cov kev siv tshwj xeeb, xws li stainless hlau txiav discs (nrog rau cov khoom siv los tiv thaiv cov khoom siv los tiv thaiv cov khoom adhesion) thiab masonry txiav discs (nrog rau kev sib txuas ntxiv los tiv thaiv cov khoom nyuaj, nkig).
Cov ntawv thov kev lag luam ntawm kev txiav discs yog dav. Hauv kev tsim cov hlau, lawv tau siv rau kev txiav cov hlau phaj, cov kav dej, thiab cov khoom siv hauv kev tsim cov tshuab, txuas hniav, thiab cov tsev. Hauv kev lag luam automotive, txiav discs yog ua haujlwm rau kev kho thiab hloov kho tsheb thav duab, cov tshuab tso pa, thiab cov khoom siv cav. Hauv kev tsim kho, lawv ua lub luag haujlwm tseem ceeb hauv kev txiav cov hlua khi, pob zeb ua pob zeb, thiab cov vuas luaj ceramic. Nyob rau hauv aerospace thiab lub zog tauj dua tshiab, siab - precision txiav discs yog siv los ua cov khoom sib sib zog nqus hlau thiab cov khoom sib xyaw nrog rau qhov ntev ntev.
Kev nyab xeeb yog qhov tseem ceeb thaum siv cov ntawv txiav, vim tias kev ua haujlwm tsis raug tuaj yeem ua rau muaj xwm txheej loj. Cov neeg siv yuav tsum tau xaiv ib qho kev txiav disc uas phim cov kev qhia tshwj xeeb ntawm lub tshuab sib tsoo (xws li, ntsuas nrawm, txoj kab uas hla) thiab cov khoom raug txiav. Ua ntej siv, tshuaj xyuas lub disc rau cov kab nrib pleb, chips, los yog lwm yam tsis xws luag, thiab xyuas kom meej tias tus neeg zov thiab spindle txiv ntoo yog ruaj khov. Thaum lub sijhawm ua haujlwm, hnav cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), suav nrog cov tsom iav kev nyab xeeb, daim npog ntsej muag, hnab looj tes, thiab hlau- cov khau khau khiab. Tsis txhob siv lub zog ntau dhau, vim qhov no tuaj yeem ua rau lub disc overheat lossis tawg, thiab tsis txhob siv cov txiav txiav rau kev sib tsoo, vim qhov no ua txhaum cov qauv kev nyab xeeb thiab txo qhov kev pab cuam lub neej.
Hauv kev xaus, txiav discs yog cov cuab yeej tseem ceeb rau kev txiav txiav hauv ntau yam kev lag luam. Los ntawm kev nkag siab txog lawv cov khoom tseem ceeb, kev faib tawm, thiab cov ntawv thov, thiab ua raws li cov txheej txheem kev nyab xeeb nruj, cov neeg siv tuaj yeem ua kom muaj txiaj ntsig zoo tshaj plaws, ua kom cov khoom zoo, thiab txo qis kev pheej hmoo ua haujlwm. Thaum xaiv cov txiav txiav, nws yog ib qho tseem ceeb rau kev koom tes nrog cov tuam txhab muaj npe nrov uas ua raws li cov qauv thoob ntiaj teb (xws li EN 12413) kom lav cov khoom ntseeg tau thiab kev ua tau zoo.
