Urwego rwo hejuru rwa 430 ibyuma bitagira umwanda
430 ibyuma bidafite ingese bifite leta zikurikira, leta iratandukanye, kurwanya umwanda no kurwanya ruswa nabyo biratandukanye.
OYA.1, 1D, 2D, 2B, N0.4, HL, BA, Indorerwamo, hamwe nubundi buryo butandukanye bwo kuvura hejuru.
Ikoranabuhanga ritunganya
1D - Ubuso bufite uduce duto duto, nabwo bita matte. Tekinoroji yo gutunganya: kuzunguruka bishyushye + annealing ishoti yikuramo + gukonjesha gukonje + gutoragura.
2D - Ifeza yoroheje-yera. Tekinoroji yo gutunganya: kuzunguruka bishyushye + annealing ishoti yikuramo + gukonjesha gukonje + gutoragura.
2B - Ifeza yera kandi ifite ububengerane nuburinganire burenze 2D hejuru. Tekinoroji yo gutunganya: kuzunguruka bishyushye + annealing ishoti yikuramo + gukonjesha gukonje + gutoragura + kuzimya no kuzunguruka.
BA - Ubuso bw'ubuso ni bwiza kandi bufite urumuri rwinshi, kimwe n'ubuso bw'indorerwamo. Tekinoroji yo gutunganya: kuzunguruka bishyushye + annealing peening pickling + gukonjesha gukonje + gutoragura + guswera hejuru + kuzimya no kuzunguruka.
No.3 - ifite uburabyo bwiza kandi busa neza. Ikoreshwa rya tekinoroji: Gutunganya no gutondekanya ibicuruzwa 2D cyangwa 2B hamwe nibikoresho 100 ~ 120 (JIS R6002).
No.4 - ifite urumuri rwiza n'imirongo myiza hejuru. Ikoreshwa rya tekinoroji: Gutunganya no gutondekanya ibicuruzwa 2D cyangwa 2B hamwe nibikoresho 150 ~ 180 (JIS R6002).
HL - Icyatsi kibisi gifite imisatsi. Tekinoroji yo gutunganya: Igipolonye ibicuruzwa 2D cyangwa ibicuruzwa 2B bifite ubunini bukwiye bwo gukuramo kugirango ubuso bugaragare ingano zihoraho.
MIRRO - hejuru yindorerwamo. Tekinoroji yo gutunganya: Ibicuruzwa 2D cyangwa 2B biri hasi kandi bisizwe neza kugirango bibe indorerwamo hamwe nubunini bukwiye bwibikoresho.
