Pambuyo pokonza, yesani kuyesa pazomwe mungayesere poyeserera (kapangidwe kogwirira ntchito yolumikizira ndi 1.6Mpa, kuthamanga koyezetsa ndi 2.4pmpa), palibe kutayikira ndi "dzino kuchoka" chodabwitsa cholumikizira chomwe chimapezeka pakuyesa, ndipo mayeso ake ndiabwino , zomwe zikutsimikizira kuti kulumikizana kwa chitoliro cha Grip kumatha kuzindikira kulumikizana kwabwino pokhapokha vuto lalikulu lokonza mapaipi.
Kulumikizana kwatsamba ndi zithunzi ndi izi:
| Kupatuka kwa ngodya | Olamulira kupatuka | Mapeto kupatuka mtunda | |
| Unsembe Standard | 4 ° ~ 5 ° | Pakati pa 3mm | 0mm-30mm |
| Cholakwika cholumikizira | 6 ° -8 ° | Pafupifupi 5mm | Pafupifupi 30mm |
