The 600 is Newing-Hall's biggest offering and boasts an impressive 30"x24" Engraving Area. This machine is controlled by the original Apex series controller & JLS software. These were 10 years ahead of the competition when first released, and still 'cut it' today. Although not recommended by the manufacturer I know of one of these machines that has been engraving stainless steel exclusively for the last 10 years. This particular machine has had very little use for the last 3 years due to the owners switching to laser.
