Parkson’s five-axis barrel cam rotary table provides high rigidity, high speed, and exceptional wear resistance.
The entire series is equipped with a near-zero backlash roller cam driver using a barrel roller cam mechanism. This design provides outstanding machining rigidity, rapid indexing motion, and a very low wear rate.
With its near-zero backlash feature, it enables ultra-precise positioning, and the high-rigidity barrel roller cam delivers the stability and accuracy required for advanced five-axis machining in machine tools.
Core Mechanism Advantages
1. Barrel Roller Cam Driver
The rotary table adopts a barrel-type roller cam mechanism that operates through rolling contact. This design delivers exceptionally high transmission efficiency, minimal friction, and extremely low wear.
2. Near-Zero Backlash
The mechanism maintains extremely tight clearances, ensuring positioning accuracy even during reversal motion or under fluctuating cutting loads. This near-zero backlash behavior enables ultra-precision positioning capabilities.
3. High-Rigidity Cam Structure
The cylindrical cam features a large contact surface and inherently high stiffness, allowing it to withstand the high torque and complex cutting forces required in advanced five-axis machining applications.
Machining Performance Features
1. High-Rigidity Cutting Performance
The robust cam structure minimizes deformation and positional drift under heavy-duty or high-load machining, improving overall stability and workpiece surface quality.
2. High-Speed Indexing and Rapid Motion Performance
The optimized cam profile provides smooth acceleration and deceleration, enabling rapid indexing and high-speed motion. This reduces non-cutting time and increases productivity.
3. Ultra-Precision Positioning
The combination of a near-zero backlash mechanism and the high-stiffness roller cam guide ensures exceptional repeatability—perfect for high-precision five-axis machining and multi-surface operations.
Durability & Maintenance Advantages
1. Low Wear, Long Service Life
Rolling contact significantly reduces friction heat and abrasion. Even during long-term high-speed operation, the mechanism maintains precision and reliability.
2. High Stability with Minimal Thermal Influence
Reduced friction means lower temperature rise, which helps preserve accuracy and minimize thermal drift during extended machining cycles.
3. Ideal for Continuous High-Duty Production
The durable structure and excellent accuracy retention make it well-suited for machine tools with long operating hours and high utilization rates.
