Kwa makasitomala ambiri omwe ali ndi zofunikira kwambiri pa kulondola kwa oyesa kuuma, kuwerengera kwa oyesa kuuma kumawonjezera kufunikira kwakukulu pa mabuloko olimba. Lero, ndikusangalala kuyambitsa mndandanda wa mabuloko olimba a Class A.—Rockwell hardness blocks, Vickers hardness blocks, Brinell Hardness blocks, HRA, HRB, HRC, HRE HRR, HV, HBW etc.
Ma block a hardness a Class A amafunikira kwambiri pankhani ya njira zokonzera, kukonza pamwamba, ndi njira zotenthetsera. Njira yopangira ma block a hardness awa imaphatikizapo njira zapamwamba zokonzera. Malo opangira ma CNC opangidwa ndi akatswiri amagwiritsidwa ntchito kuti atsimikizire kuti miyeso ya ma block a hardness ikukwaniritsa miyezo yolondola kwambiri. Gawo lililonse lodulira limasinthidwa mosamala kuti lichepetse zolakwika zilizonse zomwe zingachitike.
Pankhani yokonza pamwamba, njira zapadera zomaliza pamwamba zimagwiritsidwa ntchito. Kupukuta ndi kulumikiza molondola kumachitika kuti pakhale malo okhala ndi kukhwima kochepa kwambiri. Izi sizimangochepetsa kusokoneza kwa zinthu zomwe sizikuyenda bwino panthawi yoyezera kuuma komanso zimathandizira kuti pakhale kugwirizana pakati pa choyezera kuuma ndi pamwamba pa chipika cha kuuma, zomwe zimapangitsa kuti pakhale zotsatira zolondola kwambiri.
Njira yochizira kutentha kwa ma hard block a Class A imayendetsedwanso mosamala. Ma uvuni apamwamba ochizira kutentha okhala ndi machitidwe olondola owongolera kutentha amagwiritsidwa ntchito. Panthawi yochizira kutentha, liwiro lotenthetsera, nthawi yogwirira, ndi liwiro lozizira zonse zimayendetsedwa motsatira ndondomeko inayake. Izi zimatsimikizira kuti kapangidwe ka mkati mwa hard block ndi kofanana komanso kokhazikika, zomwe zimachepetsa bwino kupsinjika kwamkati mkati mwa zinthuzo.
Chifukwa cha njira zovuta izi, kusatsimikizika kwa kuyeza kwa ma block a hardness a Class A kumachepa kwambiri, ndipo kufanana kwawo kumakhala kwakukulu kwambiri poyerekeza ndi mitundu ina ya ma block a hardness. Amapereka maziko odalirika kwambiri pakuyesa ma hardness testers, zomwe zimathandiza ma hardness testers kuti akwaniritse kulondola kwakukulu komanso kukhazikika mu miyeso yawo. Kaya mukupanga mafakitale, kuwongolera khalidwe m'ma laboratories, kapena m'magawo ofufuza asayansi, ma block a hardness a Class A amachita gawo lofunika kwambiri komanso lofunikira, kuthandiza akatswiri kupeza deta yolondola komanso yodalirika yoyezera hardness testers.
Posankha mipiringidzo ya kuuma ya Class A, makasitomala amatha kukhala ndi chidaliro chonse pakuyesa kwa oyesa kuuma kwawo, kuonetsetsa kuti zotsatira zawo zoyesera kuuma ndizolondola komanso zogwirizana, motero amapereka chithandizo champhamvu pakuwongolera khalidwe ndi chitukuko cha zinthu zawo.
