rock drilling tools

The biggest challenge in the production and research and development of rock drilling tools is the research and development of hard alloy materials and corresponding heat treatment processes, which involve professional fields such as mining engineering, metal materials and heat treatment

The majority of technicians in the rock drilling tools enterprises is relatively older and scarcely use the advanced design software (e.g. 3-D molding software like Pro-E and CATIC). The overall technical level of them still leaves much room to improve. The rock drilling tools enterprises
