Traditional material dial tables, manufactured from either aluminum or steel, have tooling attachment holes drilled and tapped into the dial surface. Of particular interest is the pull out performance of
Pull out comparison analysis of inserts compared with aluminum Mic6, aluminum 6061-T6 and A36 steel. Insert pull out was determined using a shear strength allowable of 2,000 psi (Epoxy adhesive).
