AI Technical Summary

Technical Problem

Existing drilling techniques, including teleoperated robotics, are unsuitable for large-diameter drilling in hostile environments due to the need for multiple drill bit changes and lack of precision in axis alignment, posing risks of tool breakage and operational hazards.

Method used

A deburring and boring actuator for remotely operated robotic arms, comprising a detachable mounting base, a frustoconical cutting tip with edges, a motor for rotation, and a translation device, used in conjunction with laser drilling and gas blasting to create a bore of constant diameter, eliminating the need for tool changes and ensuring alignment.

Benefits of technology

Enables large-diameter, deep laser drilling in hostile environments with reduced risk of breakage and misalignment, achieving high operational reliability and safety by using a two-step process combining laser cutting and mechanical finishing.
