Monga tonse tikudziwa, njira iliyonse yoyesera kuuma, kaya Brinell, Rockwell, Vickers kapena portable Leeb hardness tester, ili ndi malire ake ndipo simphamvu zonse. Kwa zida zazikulu, zolemetsa komanso zosakhazikika za geometric monga zomwe zasonyezedwa mu chitsanzo chotsatirachi, njira zambiri zoyesera zamakono zimagwiritsa ntchito zoyesera zolimba za Leeb kuwongolera kuuma kwawo.
Mphamvu yoyezera njira ya Leeb kuuma woyesa ali ndi zinthu zambiri zomwe zimakhudza kuuma kwake kulondola: monga: zinthu zotanuka modulus, mowa mutu wa mpira, workpiece pamwamba roughness, kupindika utali wozungulira, pamwamba anaumitsa wosanjikiza kuya, etc. Poyerekeza ndi njira malo amodzi muyeso wa Brinell, Rockwell ndi Vickers, cholakwika ndi lalikulu kwambiri. Ngati kuuma kumafuna kulondola kwambiri, tingasankhe bwanji choyesa cholimba?
Mtundu uwu wa workpiece wolemera m'kati mwa wamba kuuma tester kuyezetsa, pamaso mayeso Mumakonda ndi kutsitsa wa woyesa kuuma, ndi kutsitsa wa kuuma Tester adzabweretsa lalikulu ntchito mu ndondomeko ntchito, kotero ife kusankha kuuma woyesa? Zotsatirazi zimalimbikitsa kugwiritsa ntchito choyesa cholimba chokhala ndi mutu wokweza mutu kuti amalize ndondomeko yonse yoyesa. Monga momwe zilili pansipa:
Njira yothetsera kuuma kumeneku imatha kuzindikira kuyezetsa kuuma kwa Rockwell/Vickers ndi Brinell kuuma molingana ndi miyezo yoyezetsa kuuma (GB/T 231.1, GB/T 4340.1, ISO6507, ISO6508, ASTM E18, etc.), ndikukwaniritsa kuyezetsa kolondola kwambiri komanso zofunikira zopangira zolemetsa zolemetsa.
Mutu wodzikweza wonyamula kuuma woyesa uli ndi benchi yokhazikika, yomwe imachepetsa cholakwika chomwe chimabwera chifukwa cha screw ndi kukweza kwa benchi yogwirira ntchito kuti muyezedwe molondola. Benchi yogwirira ntchito ndi yayikulu ndipo imatha kukhala ndi zida zazikulu zoyezera. Kuyeza kwa batani limodzi kumachepetsa kwambiri zolakwika zoyesa ndi ntchito ya tester, yomwe ili yabwino komanso yachangu.
