CITIZEN RO4 HORIZONTAL MACHINING CENTER

Technical Description

The CITIZEN RO4 Horizontal Machining Center is a high-precision CNC lathe designed for micro machining with a maximum turning diameter of 0.160" and a maximum turning length of 1.580". It features a powerful main spindle capable of speeds up to 20,000 RPM, delivering 1.00 HP standard with an optional upgrade to 1.50 HP to support high-speed, high-precision operations. The machine is equipped with two main spindles running at 20,000 RPM each and a sub spindle operating at 10,000 RPM with 0.67 HP, enabling complex multi-spindle machining. It supports simultaneous operation of two cutting tools and provides six axes of movement, enhancing machining flexibility and efficiency. The integrated design includes advanced linear motor-driven slides, minimizing backlash and improving responsiveness and noise reduction. Compact in size, the RO4 reduces floor space requirements significantly while maintaining high productivity. With up to 17 tool positions and live tooling capabilities, it allows extensive machining operations including turning, drilling, and tapping in a single setup. The machine’s construction emphasizes thermal displacement control for stability during extended machining cycles, making it ideal for industries requiring precision small-part manufacturing such as watchmaking, medical devices, electronics, and aerospace. Overall, the CITIZEN RO4 delivers exceptional speed, precision, and multi-functionality within a compact footprint for efficient mass production of miniature components.
