Boring connecting rods Part 1 - This ended up as three parts. Part 1 shows the machining operations using TSC style brazed carbide tooling with surface footage from 160SFPM to about 250SFPM and feed-rates from .003" to .007" per revolution, depth of cut ranges from .125" to .0003" over three boring operations. Tools for the facing were TSA brazed front and AL brazed for the back (AL is a lathe type tool). Parts 2 & 3 I discuss the setup, adjustments, tool types, grind profiles, tool setting and other stuff. Note the boring tools are breaking chips in all setting parameters with hand ground brazed carbide tools and leaving good finishes even down to the .0003" per side cut. This is not easy with welded bores. Thanks for watching!
