How Roku-Roku Precision Milling Works

What Makes Roku-Roku Precision Milling Different

Roku-Roku’s 3-axis CNC machines use contactless magnetic linear drive technology instead of conventional ballscrew feed systems. This eliminates mechanical wear, removes stick-slip motion, and delivers consistent micron-level accuracy across every axis of travel. The result is a 3-axis milling machine built for applications where standard machining tolerances are not tight enough medical tooling, aerospace components, precision die and mold work, and graphite electrode machining.

Key differentiators:

  • Accuracies under 0.0001" as standard across the 3-axis milling lineup
  • Spindle speeds from 25,000 to 90,000 RPM
  • Magnetic linear drives on flagship models (Android II, Vision 300)
  • HSK tool holders (E25, E40, E50) across all models
  • ATC positions from 20 to 60 tools depending on model
  • Flood coolant or dry machining configurations available
