What is Roller Cam Drive Technology?
An overview of how roller cam drives work in CNC rotary tables and why they offer high rigidity and zero backlash.
Introduction
Roller cam drive technology is a premium mechanical solution for CNC rotary tables. Unlike traditional worm gears, it uses a unique contact mechanism to transmit motion.
1. How it Works
The drive consists of a globoidal cam and a turret with cylindrical rollers. The cam meshes with the rollers under preload. As the cam rotates, the rollers roll along the cam's profile without sliding.
2. Key Advantages
Zero Backlash: Due to the preload, both sides of the roller are in contact with the cam, eliminating backlash.
High Rigidity: The rolling contact distributes the load across multiple rollers, making it highly resistant to cutting forces.
High Speed: Because it's rolling friction rather than sliding friction, it generates less heat and can achieve higher indexing speeds.
3. Maintenance
Roller cam tables require clean, high-quality lubricating oil. Because there is no sliding friction, wear is minimal if maintained properly.
Conclusion
Roller cam drives are ideal for high-precision, high-speed multi-axis machining. At DAYI, we utilize this technology to ensure maximum stability.
