Granite ndi chinthu chodziwika bwino chopangira zida zamakina chifukwa cha kuuma kwake, kulimba kwake komanso kukana kuvala.Komabe, pakhoza kukhala zolakwika mu zigawo za makina a granite zomwe zingakhudze khalidwe lawo ndi ntchito zawo.
Chimodzi mwa zolakwika zomwe zimachitika pamakina a granite ndi ming'alu.Izi ndi ming'alu kapena mizere yomwe imawoneka pamwamba kapena mkati mwa chigawocho chifukwa cha kupsinjika maganizo, kukhudzidwa kapena kusintha kwa kutentha.Ming'alu imatha kufooketsa chigawocho ndikupangitsa kuti chilephere msanga.
Chilema china ndi porosity.Zigawo zamakina a porous granite ndizomwe zimakhala ndi matumba ang'onoang'ono a mpweya kapena ma voids mkati mwake.Izi zitha kuwapangitsa kukhala osalimba komanso osavuta kusweka kapena kusweka chifukwa cha nkhawa.Porosity imathanso kukhudza kulondola kwa gawolo, zomwe zimatsogolera ku zolakwika zamakina.
Chilema chachitatu ndi kumaliza pamwamba.Zigawo zamakina a granite zitha kukhala ndi mawonekedwe osagwirizana kapena owoneka bwino omwe angakhudze magwiridwe antchito awo.Ukaliwu ukhoza kuyambitsa mikangano ndikupangitsa kuti chigawocho chiwonongeke.Zingapangitsenso kukhala kovuta kukwera kapena kusonkhanitsa chigawocho moyenera.
Potsirizira pake, ubwino wa granite womwe umagwiritsidwa ntchito ungakhudzenso mankhwala.Granite yamtengo wapatali imatha kukhala ndi zonyansa kapena zosagwirizana zomwe zingakhudze kuuma kwake, kulimba kwake komanso kukana kuvala.Izi zitha kubweretsa kusinthidwa pafupipafupi komanso kukonza zida zamakina.
Komabe, ndikofunikira kuzindikira kuti zolakwika izi zitha kuchepetsedwa kapena kuthetsedwa ndi njira zopangira zopangira komanso njira zowongolera.Mwachitsanzo, ming'alu imatha kupewedwa pogwiritsa ntchito granite yabwino komanso kuwongolera kutentha ndi kupsinjika pakupanga makina.Porosity imatha kuthetsedwa pogwiritsa ntchito njira ya vacuum impregnation kuti mudzaze ma voids ndi utomoni kapena polima.Kumaliza pamwamba kumatha kupitilizidwa ndi kupukuta ndi kugwiritsa ntchito zida zodulira mwatsatanetsatane.
Pamapeto pake, zida zamakina a granite ndi njira yodalirika komanso yokhazikika pamakina.Poonetsetsa kuti zopanga ndi zowongolera zoyenera kuchita, zolakwika zitha kuchepetsedwa ndipo moyo wautali komanso magwiridwe antchito a zigawozo zitha kukulitsidwa.
