Kev nyab xeeb kev ua tau zoo ntawm polycrystalline pob zeb diamond saw hniav yog qhov teeb meem zoo uas tsis tuaj yeem tsis quav ntsej, vim tias "cov hniav poob" vim kev tsim khoom lossis siv cov laj thawj cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov saw hniav thiab kev nyab xeeb ntawm tus neeg siv khoom. Pob zeb diamond pom hniav zoo ib yam, yog tias koj tsis yog tus kws tshaj lij, nws nyuaj rau pom qhov zoo thiab qhov tsis zoo ntawm qhov muag liab qab. Txawm li cas los xij, tsuav yog koj paub txog kev paub thiab ua tib zoo saib xyuas, koj tseem tuaj yeem pom cov txiaj ntsig ntawm tag nrho cov khoom los ntawm qee qhov tsis zoo.

Yog hais tias lub taub hau ntawm cov pob zeb diamond polycrystalline saw hniav tsis nyob ntawm tib txoj kab ncaj nraim, nws txhais tau hais tias qhov loj ntawm lub taub hau txiav yog qhov tsis sib xws, qee qhov yuav dav thiab qee qhov yuav nqaim, uas yuav ua rau tsis ruaj khov thaum txiav pob zeb thiab cuam ​​tshuam qhov zoo ntawm cov saw hniav. Yog hais tias lub arc-shaped nto nyob rau hauv qab ntawm lub taub hau cutter yog kiag li fused nrog lub substrate, yuav tsis muaj qhov khoob. Cov qhov khoob qhia tau hais tias qhov arc-shaped nto nyob rau hauv qab ntawm lub pob zeb diamond pom hniav tsis yog tag nrho nrog rau lub substrate, feem ntau vim hais tias lub arc-zoo li tus nto nyob rau hauv qab ntawm lub cutter lub taub hau yog unevenly.

Xyuas tias qhov siab dua qhov hardness ntawm polycrystalline pob zeb diamond pom hniav matrix yog, qhov tsawg dua nws yuav deform. Yog li ntawd, seb lub matrix hardness ua tau raws li tus qauv yuav cuam tshuam ncaj qha rau qhov zoo ntawm cov saw hniav thaum vuam los yog txiav. Kub-kub vuam yuav tsis deform, thiab nws yuav tsis deform nyob rau hauv quab yuam majeure tej yam kev mob. , nws yog ib qho zoo substrate, thiab tom qab tau ua tiav rau hauv sawb, nws kuj yog ib tug zoo saw hniav.
