Ikigeragezo gikomeye cya Rockwell nikigereranyo cyubwoko bwa Rockwell.Ikoresha imbaraga nto zo kugerageza.Mugihe ugerageza udukoryo duto kandi duto cyane, ukoresheje ibizamini bya Rockwell bigoye bizaganisha kubipimo bidahwitse.Turashobora gukoresha superficial Rockwell igerageza.Ikizamini cyo gukomera kirashobora kandi gukoreshwa mugupima ibihangano hamwe nibice bikomye.
Ihame ryayo ryo kwipimisha rirasa neza neza na Rockwell igerageza.Itandukaniro nuko imbaraga zambere zipimisha ari 3KG, mugihe imbaraga zambere zo kwipimisha zisanzwe za Rockwell zikomeye ni 10KG.
Urwego rwo hejuru rwa Rockwell rukomeye rwipimisha urwego urwego: 15KG, 30KG, 45KG
Indenter ikoreshwa mugupima superficial Rockwell igerageza ihuye nigeragezwa rya Rockwell:
1. 120 degree diamant cone indenter
2. 1.5875 umupira wumupira
Urutare rudasanzweigipimo cyo gupima igipimo:
HR15N, HR30N, HR45N, HR15T, HR30T, HR45T
(Igipimo cya N gipimwa na indimu ya diyama, naho igipimo cya T gipimwa n'umupira w'icyuma)
Gukomera biragaragazwanka: gukomera agaciro wongeyeho igipimo cya Rockwell, kurugero: 70HR150T
15T bisobanura umupira wumupira wicyuma ufite imbaraga zose zipima 147.1N (15 kgf) hamwe na indenter ya 1.5875
Ukurikije cha yavuzwe haruguruivangura, superficial Rockwell ifite ibyiza bikurikira:
1. Kubera ko ifite ebyiriimitwe yigitutu, irakwiriye kubikoresho byoroshye kandi bikomeye.
2. Imbaraga zipimisha ni smaller kurenza iya Rockwell igerageza, kandi ibyangiritse byakazi byakazi ni bito cyane.
3. Gutoza ikizamini gitoe irashobora gusimbuza igice igice cya Vickers igerageza, igereranijwe mubukungu kandi ihendutse.
4. Inzira yikizamini irihuta kandi igihangano cyarangiye gishobora kugaragara neza.
