2008 Tsudakoma RNA-250R 4th Axis Rotary Table | High Clamping Force | 10" Table

2008 Tsudakoma RNA-250R CNC Rotary Table

High-Clamping Torque | 10" Faceplate | S/N 081953

"The Heavy-Duty Standard for Precision 4th-Axis Production"

Available for immediate acquisition is this 2008 Tsudakoma RNA-250R, a high-performance 4th-axis solution engineered for shops that refuse to compromise between speed and rigidity. While many rotary tables are designed for light indexing, the RNA series is built for heavy-duty milling. Featuring Tsudakoma's proprietary dual-disk hydraulic/pneumatic clamping system, this table delivers massive holding torque to ensure zero part deflection during aggressive side-milling or heavy-diameter drilling.

This 2008 unit (S/N 081953) is a prime example of Japanese machine tool excellence. Its compact "R" design integrates the motor close to the casting, allowing it to fit easily into mid-sized VMCs without significantly reducing your machine's X-axis travel.

Key Features & Dealer Advantages

• Ultra-Rigid Clamping Force: The "Dual-Disk" brake system provides nearly double the clamping force of standard rotary tables. This prevents "brake drag" and ensures the table stays dead-on during high-force operations.
• Internal Motor Housing: The motor is tucked inside the main casting footprint. This prevents the motor from interfering with machine doors or tool changers, a common issue with side-mount rotary units.
• Precision Worm Gear Set: Constructed with a high-tensile brass worm wheel and a hardened steel worm screw. This pairing provides superior wear resistance and maintains tight indexing tolerances over decades of use.
• High-Load Cross-Roller Bearings: Engineered to handle massive radial and axial loads simultaneously, making this table suitable for large, off-center workpieces.
• Versatile Connectivity: Currently configured with standard industrial connectors, easily adaptable to Haas, Fanuc, or Mazak 4th-axis drive cards.
