2003 ROKU ROKU HC435 VERTICAL MACHINING CENTERS

Technical Description

The 2003 ROKU ROKU HC435 is a 3-axis high-speed precision graphite and hard metal machining center from Japanese builder Roku-Roku, designed for electrode milling and complex precision component production. The HC435 features a bridge-type monoblock structure for maximum static and dynamic rigidity, providing positioning accuracy of plus or minus 0.000059" and repeatability of plus or minus 0.000012", consistent with jig-borer precision standards. Axis travels of 16" in X, 13" in Y, and 7.9" in Z define the compact, precision cutting envelope. The HSK-E40 taper spindle operates at up to 36,000 RPM, enabling high-speed finishing of graphite electrodes, copper electrodes, hardened steel mold inserts, and precision tooling. Intelligent Velocity Control (IVC) and NANO Interpolation in the Fanuc 31i-A5 CNC provide smooth surface finish at high feed rates. Graphite dust sealing protects precision slideways and components from abrasive electrode material. The HC435 is suited to EDM tooling production, precision micro-mold manufacturing, and applications requiring sustained high-speed accuracy.
