Ikholomu izinyo bit bit Rock drill bit Plum blossom bit column izinyo bit Iimpawu zemveliso:
1. Intsika yezinyo yekholomu inokusebenza kakuhle kwemigodi: usebenzisa iteknoloji yobunini obubodwa, amazinyo eqhosha le-alloy enzima, ubunzima (HRA) ≥92.5, amandla ≥2800N.
2. Ubomi bomzimba webhulukhwe yentsinjana yezinyo yonyuka ngama-50%: umzimba webhulukhwe uphathwe ngobushushu kwaye uqingqelwe ngokuchanekileyo, umzimba webhulukhwe womelele kakhulu kwaye awuqhekeki.
Singomnye wabavelisi behamile be-rock edumileyo eTshayina, esebenza ngokukhethekileyo kwimveliso yezixhobo zokomba amatye ezinomsebenzi ogqwesileyo kunye nemathiriyeli ephezulu, eyenziwe ngokungqongqo ngokwemigangatho yomgangatho wemizi-mveliso kunye ne-CE, isatifikethi senkqubo yolawulo lomgangatho we-ISO9001.Aba matshini bokomba kulula ukuyifaka, ukusebenza kunye nokugcina.Oomatshini bokomba banexabiso elifanelekileyo kwaye kulula ukuyisebenzisa.I-rock drill iyilelwe ukuba yomelele kwaye yomelele, ingonakali lula, kunye noluhlu olupheleleyo lwezixhobo zokuqhuba amatye.
