| Abstract: | In view of the actual requirements of the hard-rock large diameter shaft drilling engineering,the paper analyses the relationships among the sphere teeth hob's rock breaking and the technological parameters including axial pressure,rotary speed,well-flushing and fragment-discharging parameters etc.,and offers the relevant calculation formulas. Moreover,the paper gives the factors which should be considered on rational use of cutters,refers to the relevant researches and test results from Hhghes company in U... |
