Technical standards for DTH drill bits with pressed alloy teeth
2024-05-29
Carbide column teeth must be chamfered and rounded: When grinding the outer circle, increase the amount of coolant to fully cool the alloy teeth. Pay special attention to controlling the feed amount: the feed amount is <0.03mm during rough grinding, and the feed amount does not exceed 0.01mm during fine grinding. The surface finish reaches 7, and the taper and ovality should be less than 0.008mm
