SG-1645: Electrochemical Burr-Free Surface Grinder

The Tridex SG-1645 Burr-Free Electrochemical NC/CNC Surface Grinder is a faster alternative to traditional surface grinding. By providing burr-free and low-force grinds that leave no heat-affected zones it virtually eliminates the need for deburring or other corrective secondary operations. The SG-1645 comes standard with conversational NC control with the option for Mitsubishi CNC controls. For grinding points on wires or medical needles, the Tridex PGS-100 Point Grinding System can be easily integrated.
