Revolutionizing 5-Axis Machining with Sankyo Automation’s RollerDrive Trunnion Tables

When it comes to high-precision 5-axis machining, accuracy, repeatability, and efficiency are paramount. Traditional rotary tables rely on worm gears or direct-drive motors, but these designs often introduce backlash, wear over time, or require frequent maintenance. Sankyo Automation’s RollerDrive Trunnion Tables offer a cutting-edge alternative—one that delivers unmatched precision, rigidity, and longevity while maximizing machining efficiency.

What Sets the RollerDrive Trunnion Apart?

At the core of Sankyo’s trunnion tables is the RollerDrive mechanism, a zero-backlash globoidal cam and roller follower system. This unique design provides exceptional torque transmission, absolute positioning accuracy, and permanent rigidity, ensuring that your machining center operates with precision for years without performance degradation.

Unlike traditional worm gear systems that require mechanical clamping to hold position, the RollerDrive design eliminates the need for clamping—saving valuable cycle time while maintaining a rock-solid hold under cutting forces. Additionally, the cam mechanism does not wear like worm gears, which means zero-loss accuracy over time—even after millions of indexing cycles.

Key Features & Benefits

Unrivaled Precision & Accuracy

• Zero-backlash design ensures ultra-smooth 5-axis machining without the need for frequent recalibrations.

• Permanent accuracy that does not degrade over time, eliminating the need for mechanical adjustments.

• Repeatability within 4–8 arc-seconds, providing superior consistency for precision parts.

Increased Productivity & Efficiency

• Eliminates clamping/unclamping delays, reducing non-cutting time by up to 30%.

• Fast indexing speeds, allowing 90-degree moves in as little as 0.3–0.4 seconds.

• Rigid load-bearing design, capable of supporting workpieces up to 300 kg.

Low Maintenance, High Durability

• The enclosed oil-bath cam mechanism requires only periodic lubrication, ensuring long-term reliability.

• No backlash adjustments needed, unlike worm gears that wear and introduce positional errors over time.

• Designed for high-volume production environments, ensuring long-lasting, trouble-free operation.

Applications: Where the RollerDrive Trunnion Excels

Sankyo’s 5-axis trunnion tables are trusted across multiple industries, enhancing production efficiency in:

• Aerospace: Perfect for machining complex components like turbine blades and impellers with tight tolerances.

• Automotive: Ideal for high-volume production of engine parts, transmissions, and precision automotive components.

• Medical: Enables accurate multi-angle machining of orthopedic implants and surgical instruments.

• Die & Mold Making: Provides precise control for cutting intricate mold cavities and tooling surfaces.

• Cutting Tool Manufacturing: Ensures stable, repeatable indexing for producing cutting tools and inserts.

How Does It Compare to Other Trunnion Tables?

Compared to traditional worm gear or direct-drive rotary tables, Sankyo’s RollerDrive technology offers a unique combination of precision, speed, and durability:

• Vs. Worm Gear Systems: Traditional worm gears develop backlash over time and require clamping. Sankyo’s RollerDrive eliminates backlash and allows for direct, rigid cutting without additional mechanical locking.

• Vs. Direct-Drive (Torque Motor) Tables: While torque motor tables offer high speed, they struggle with heat buildup and lower torque output. Sankyo’s cam-based system multiplies servo torque, providing superior load-bearing capacity and long-term reliability.

• Vs. Harmonic Drive Systems: Harmonic drives wear out faster and have limited load capacity. Sankyo’s cam mechanism is designed for industrial-grade machining, offering better rigidity and longevity.
