I'v brought up this topic before, shoptalkforums, PP and I think here, but have never gotten a finished result/direction. I know that the topic is filled with proprietary beliefs, but there must be some good experience here or a source of reference to expand our knowledge.
Thanks, L. McChesney |

I was just trying to make a point that it works. It's affect on aluminum is much less than on iron, but we have seen the difference in how the aluminum machines after it's been cyro'ed. The affect on cast AL is greater than on extruded, fyi, since the grain structure is already aligned in the extrusion due to the high pressures during forming. That is why Nickies are made out of an extruded tube, rather than solid billet. Not to mention it adds a wee bit of time to machining to have to hog out a solid tube....and talk about scrap!
