Abrasive sivs yuav tsum muaj lub zog siab, ua haujlwm zoo thaum tshav kub kub, ua haujlwm siab, thiab siab hardness. Qhov no nthuav tawm qhov tsis sib haum xeeb nrog qhov yuav tsum tau ua kom yooj yim. Mechanical dabtsi yog khoov yog ib txoj hauv kev zoo los daws qhov kev tsis sib haum xeeb no.
Kev khoov yuav ua rau txoj siv tawv abrasive rau bending motions ntawm cov ces kaum sib txawv nyob rau hauv nro, xws li hla nws los ntawm ib txheej ntawm me me - txoj kab uas hla rollers - ua txoj kev khoov. Lub nraub qaum ntawm cov cuab yeej abrasive yog nyob rau hauv kev sib raug zoo nrog lub txiav ntug, tsim kom tsis tu ncua, nplua tawg hauv txheej abrasive, yog li ua tiav cov nyhuv muag. Vim tias nws ua tiav kev tawg tas li mechanically, nws tseem hu ua mechanical dabtsi yog khoov. Lub℃ntawm dabtsi yog khoov qhia txog qhov softness, thiab cov kev taw qhia dabtsi yog khoov qhia lub directionality ntawm abrasive softness.
Lub℃ntawm dabtsi yog khoov nyob ntawm lub vojvoog ntawm curvature ntawm cov cuab yeej dabtsi yog khoov thiab lub siab exerted los ntawm dabtsi yog khoov cuab yeej ntawm lub abrasive siv. The smaller the radius of curvature of the bending tool and the greater the pressure exerted by the bending tool on the abrasive belt, the denser and deeper the continuous cracks, resulting in greater bending and a softer abrasive belt.
Hoob ntawm kev hloov pauv tau muab faib ua 5 hom:
90℃Flexibility:
Kuj hu ua unidirectional yooj, lub flexing cutter yog nyob rau ntawm ib tug 90℃lub kaum sab xis mus rau cov kev taw qhia ntawm lub abrasive lub zog, lub ntsiab lus ntawm tawg kev taw qhia yog perpendicular mus rau lub longitudinal kev taw qhia ntawm lub abrasive. Qhov no yog hom yooj yim tshaj plaws ntawm kev hloov pauv. Ib txoj siv tawv abrasive uas tau dhau 90℃kev hloov pauv hloov tau yooj yim hauv nws txoj kab ntev.
Ob 45℃flexures:
Kuj tseem hu ua bidirectional flexures, txoj kev no siv ob lub flexure cutters, sib tshuam cov pwm txoj kev khiav ntawm ob lub kaum sab xis 45 degree, nrog cov kab nrib pleb khiav diagonally. Pwm flexed nyob rau hauv txoj kev no yog hloov tau nyob rau hauv cov kev taw qhia ntawm ib tug 45℃lub kaum sab xis rau lawv longitudinal kev taw qhia.
Peb -dimensional curvature, piv txwv li, 90℃+ ob 45℃curvature:
Daim ntawv curvature no yog qhov sib npaug ntawm thawj ob. Lub pwm zoo li no yog hloov tau nyob rau hauv ob qho tib si nws longitudinal kev taw qhia thiab nyob rau hauv cov kev taw qhia ntawm 45℃mus rau longitudinal kev taw qhia.
Multidirectional dabtsi yog khoov (Q-bending):
Daim ntawv khoov no tau ua tiav los ntawm cov txheej txheem tshwj xeeb uas tso cai rau cov pwm tuaj yeem khoov tau zoo nyob rau hauv txhua qhov kev qhia, ua rau muaj kev cuam tshuam zoo heev.
0℃flexure (L-flexure):
Qhov no kuj yog ib hom unidirectional flexure, qhov twg cov kev taw qhia tawg yog thaum uas tig mus rau longitudinal kev taw qhia ntawm lub abrasive. Abrasives flexed nyob rau hauv txoj kev no yog flexed nyob rau hauv lawv transverse kev taw qhia. Qhov kev hloov pauv no tau ua tiav los ntawm cov cuab yeej tshwj xeeb thiab feem ntau tsis siv ib leeg, tab sis ua ke nrog bidirectional lossis tridirectional flexure kom ua tiav cov txiaj ntsig zoo dua li kev hloov pauv ntau.
