Imikorere yumutekano ya diyama ya polycrystalline yibiti nikibazo cyiza ntigishobora kwirengagizwa, kuko "gutakaza amenyo" kubera umusaruro cyangwa gukoresha impamvu bigira ingaruka kuburyo butaziguye kumikorere yicyuma ndetse numutekano bwite wumukoresha. Diamond yabonye ibyuma bisa nkaho bigaragara, niba utari umunyamwuga, biragoye kubona ibyiza n'ibibi n'amaso. Ariko, mugihe cyose uzi neza uburyo-ukareba neza, urashobora kubona ingaruka yibicuruzwa byose ukoresheje utunenge duto.

Niba imitwe yo gukata ya polycrystalline diamant yabonye icyuma kitari kumurongo umwe ugororotse, bivuze ko ubunini bwumutwe wogukata budasanzwe, bimwe bishobora kuba binini kandi bimwe bishobora kuba bigufi, ibyo bikazana gukata kudahungabana mugihe cyo gutema amabuye na bigira ingaruka kumiterere yicyuma. Niba ubuso bumeze nka arc hepfo yumutwe wumutwe wahujwe rwose na substrate, ntihazabaho icyuho. Ibyuho byerekana ko ubuso bumeze nka arc hepfo ya diyama yabonye icyuma kidahujwe rwose na substrate, cyane cyane ko ubuso bumeze nka arc munsi yumutwe wumutwe utaringaniye.

Reba neza ko hejuru ya diyama ya polycrystalline yabonye materix ya blade, ntabwo bishoboka cyane ko ihinduka. Kubwibyo, niba gukomera kwa matrix byujuje ubuziranenge bizagira ingaruka ku buryo butaziguye ubwiza bwicyuma kibonye mugihe cyo gusudira cyangwa gukata. Ubushuhe bwo hejuru bwo gusudira ntibuzahinduka, kandi ntibuzahinduka mubihe bidasanzwe. , ni substrate nziza, kandi nyuma yo gutunganyirizwa mubyuma, ni nicyuma cyiza.
