HAKUSAN, Ishikawa, Japan, Oct 26, 2026 – Nakamura-Tome Precision Industry Co., Ltd. is pleased to announce the launch of its new B-axis Multitasking Machine, RX-50.
In recent years, manufacturers of high-value components such as watch components, medical parts, and jewelry have faced increasing demands for tighter dimensional accuracy and superior surface finishes. At the same time, the materials used for these products are often expensive, making it essential to minimize material losses caused by machining defects. To address these market needs, Nakamura-Tome developed the RX-50, a new B-axis multitasking machine.
RX-50 was developed not to achieve quality through repeated trial cuts, but to produce a finished part right from the very first piece. Rather than pursuing production efficiency for mass production alone, it was designed to deliver the high machining accuracy needed to reliably produce finished products from valuable, low-volume workpieces.
The RX-50 features a simple configuration without turrets, consisting of the opposed twin spindles and a tool spindle, similar to the NTRX-300 series. This design enables a wide machining envelope despite the machine’s compact footprint.
A key feature of the RX-50 is its machine structure, refined to achieve exceptional machining accuracy. Its tool spindle is structurally independent of the other machining systems, which minimizes the influence of external factors such as vibration and heat, and enhances the tool spindle’s own positioning accuracy.
The machine adopts a unique symmetrical structure, with the opposed twin spindles arranged symmetrically on the left and right of a vertical column on the horizontal bed. This design provides excellent thermal stability, enabling the machine to maintain high-precision machining performance over long periods of operation. Furthermore, even in production environments involving continuous operation and tool changes, the machine delivers high dimensional repeatability, ensuring consistently high-quality and reliable machining.
Compact Tool Spindle “NT Smart Cube”
The machine is equipped with our proprietary compact tool spindle unit, the “NT Smart Cube” (length: 299 mm). It delivers a maximum spindle speed of 30,000 min⁻¹, enabling high-speed and high-precision machining. In addition, it features an ATC (Automatic Tool Changer) system, with tools stored in an ATC magazine. A standard configuration allows for compact storage of 60 tools, with an option to expand up to 119 tools. Because the additional magazine is arranged vertically, tool capacity can be expanded without increasing the machine’s footprint, enabling both high productivity and efficient use of valuable floor space.
Furthermore, an impressive chip-to-chip time of just 3.3 seconds has been achieved. In addition, the machine is equipped as standard with “ChronoCut α,” software that reduces various idle times and optimizes both machining and non-machining processes. As a result, cycle times have been significantly shortened.
Compact Machine Design
The machine has a compact footprint of just 3,000 mm × 2,000 mm (4,309.2 mm × 2,378 mm including the chip tank and conveyor), making it exceptionally compact for a multitasking machine with a tool spindle.
Its space-saving design allows installation in limited floor space while maintaining high productivity, providing greater flexibility in factory layout and production planning.
A Multitasking Machine Designed to Cut the Burden on Operators
The control panel is designed with usability in mind and can be both swiveled and repositioned, allowing operators to work from the most comfortable and efficient position. Because the panel can be moved close to the ATC magazine, tool setup and preparation can be performed quickly and easily.
In addition, the distance from the front of the machine to the spindle center is limited to just 450 mm, providing excellent access to the work area while reducing operator fatigue.
Precision in Every Part
The RX-50 is a B-axis multitasking machine developed for high-value field such as watch, medical, and jewelry manufacturing. Combining a high-precision machine structure that avoid wasting expensive materials, a high-speed automatic tool changing system, and a compact footprint, the RX-50 delivers new values to our customers’ manufacturers under the concept of “Precision in Every Part.”
“When machining high-value components such as precision electronic parts, medical components, jewelry, and watch components, it is essential not to fail on any single part, whether producing one or one hundred. The RX-50 was designed to eliminate repeated trial cuts and produce a finished part from the very first piece. Guided by the concept of “Precision in Every Part.”, it brings together a high-precision machine structure, stable machining performance, and strong cutting capability.
The RX-50 is a compact B-axis multitasking machine that handles a wide range of machining applications and reliably turns expensive workpieces into high-value finished products. We invite our customers to experience the new RX-50 firsthand. Let’s cut the burden of manufacturing together.” said, Shogo Nakamura, CEO.
