Monga tonse tikudziwira, njira iliyonse yoyesera kuuma, kaya ndi Brinell, Rockwell, Vickers kapena choyesera kuuma chonyamulika cha Leeb, chili ndi zofooka zake ndipo sichili ndi mphamvu zonse. Pazinthu zazikulu, zolemera komanso zosakhazikika monga zomwe zawonetsedwa pachitsanzo chotsatirachi, njira zambiri zoyesera zamakono zimagwiritsa ntchito zoyesa kuuma zonyamulika za Leeb kuti ziwongolere kuuma kwawo.
Njira yoyezera mphamvu ya Leeb hardness tester ili ndi zinthu zambiri zomwe zimakhudza kulondola kwake: monga: elastic modulus ya zinthu, kugwiritsa ntchito mutu wa mpira, workpiece surface roughness, curvature radius, surface harvest layer depth, etc. Poyerekeza ndi njira zoyezera zosasinthika za Brinell, Rockwell ndi Vickers, cholakwikacho ndi chachikulu kwambiri. Ngati kuuma kumafuna kulondola kwambiri, kodi tingasankhe bwanji hardness tester?
Mtundu uwu wa ntchito yolemera poyesa kuuma kwa thupi, kutsitsa ndi kutsitsa kuuma kwa thupi kusanachitike, komanso kutsitsa kuuma kwa thupi kudzabweretsa ntchito yaikulu pakugwira ntchito, ndiye tingasankhe bwanji kuuma kwa thupi? Zotsatirazi zimalimbikitsa kugwiritsa ntchito kuuma kwa thupi komwe kuli ndi kapangidwe kokweza mutu kuti mumalize njira yonse yoyesera. Monga momwe zasonyezedwera pansipa:
Njira yoyesera kuuma iyi imatha kukwaniritsa mayeso a Rockwell hardness testing/Vickers ndi Brinell hardness testing molingana ndi miyezo yoyesera kuuma (GB/T 231.1, GB/T 4340.1, ISO6507, ISO6508, ASTM E18, etc.), ndikukwaniritsa zofunikira zoyesera molondola komanso zopangira bwino za zida zolemera.
Choyezera kuuma kwa mutu chokha chili ndi benchi lokhazikika, lomwe limachepetsa cholakwika chomwe chimachitika chifukwa cha screw ndi kukweza benchi logwirira ntchito kuti chikhale cholondola poyesa kuuma. Benchi logwirira ntchito ndi lalikulu kukula kwake ndipo limatha kunyamula zida zazikulu zoyezera. Kuyeza kwa batani limodzi kumachepetsa kwambiri cholakwika choyesera ndi ntchito ya choyezera, zomwe ndi zosavuta komanso zachangu.
