    Another Significant Innovation! Warner and Swasey was the first turning machine builder to actively promote the use of this method for the machining of bar stock in diameters of around 2.5" and larger. By cutting the bar stock into slugs with an automatic saw, and then predrilling the slugs whenever possible, the parts can be made more efficiently on a smaller and faster machines.

    W/S stressed this concept, and practiced it in its own shop and played it up in excellent advertising and in trade magazine articles. It talked about the fact that this approach would become increasingly important in years ahead, as improved cutting materials became common, and that rotating large bars at high speeds toproperly use the new cutting tools would soon be impractical. Of course, a vital aspect was that these slugs could be processed over the steadily growing family of chuckers that W/S was offering to the market: a family without comparison in terms of breadth, operational ease, productivity and longevity
