Design, Fabricate and Test a Conical Borer
Abstract
The report summarizes effort completed during the first year of a proposed three-year effort to design, fabricate, and test a conical self- advancing and self-rotating boring machine. The conical borer will use a proven and economical mechanical fragmentation system - roller cutters - and will operate as a reaming device to enlarge an existing 8-3/4 inch pilot hole to a final 36 inch bore. The concept offers a substantial improvement over the present state-of-the-art, particularly in hard-rock boring applications and can be rapidly put to practical use using proven components.
