Oct 17, 2011 So what I am really after are the tools and techniques for how to machine glass in low quantities. My understanding of the normal "grinding" process is that a tool is made (as in the "Generating Spherical surfaces thread) or a hell of a lot of grinding take place (for a lens that has a small radius of curvature relative to its diameter).

Apr 19, 2013 Hard to machine materials often require the use of the upper end of the allowable drilled hole tolerance to prevent tap breakage. To be successful, a shop should establish its own minor and major diameter limits, but it could be restricted to working with only about half of the allowable tolerance to prevent breakage, yet still produce an acceptable “complete” thread
