    Neat! Looks like Sigma invests in the most modern machinery. I have been working for and with Mitsubishi EDM for close to a decade, and the EDM’s pictured are the most modern and current in their line. The Mitsui Seiki’s are pretty modern as well, and among the finest machine tools out there. Having been in the machining industry for 20 years, I have a whole new respect for Sigma. It’s been my experience that companies that invest in the latest and greatest are often on the cutting edge of manufacturing.
