2003 ROKU ROKU GR435N VERTICAL MACHINING CENTERS

Technical Description

The 2003 ROKU ROKU GR435N is a 3-axis high-speed graphite electrode machining center from Japanese builder Roku-Roku, engineered specifically for the precision milling of EDM graphite and copper electrodes at extreme spindle speeds. The GR435N is built to jig-borer accuracy standards, with positioning accuracy and thermal stability optimized for sub-micron electrode geometry production. The compact CAT20 taper spindle operates at up to 36,000 RPM, enabling fine chip-load cutting of graphite blocks with minimal electrode breakage and precise dimensional control. The machine is controlled by a Fanuc 16MC CNC with RISC look-ahead processing for high-speed contour following. The GR435N features an integrated graphite dust collection system and sealed slideways to protect precision components from abrasive graphite particulate. The machine's compact bridge-type monoblock structure provides high static and dynamic rigidity for accurate, vibration-free electrode geometry in production EDM tooling environments. It is best suited to die and mold shops producing complex electrode libraries for injection mold and stamping die EDM operations.
