Fukudaco Active Balancing System

Manufacturer: Fukudaco
Overview
It reduces vibrations caused by various factors, including imbalances due to workpiece shape, tooling, and wear.
Applications
- Grinding
- Lathes
- Industrial fans
Features
- Balance correction completes in just a few seconds without stopping rotation.
- The ring-type design allows for relatively easy retrofitting.
- Achieves a balance level of 1.0G or lower.
- Enables quick and automatic balancing without stopping rotation.
Active Balancing System Operating Principle

By reducing vibrations and dynamic runout, the active balancing system enhances machining accuracy. Resonance is minimized, thereby extending tool life. The system allows for increased rotational speeds, leading to reduced cycle times. It also shortens setup times, thereby improving productivity. Additionally, it enhances safety through simple operation.
Benefits of Implementing a Balancing System
- Improved Machining Accuracy: Reduces vibrations and dynamic runout, enhancing overall machining precision.
- Extended Tool Life: Minimizes resonance, leading to a longer tool lifespan.
- Increased Rotational Speed: Allows higher rotational speeds, which shortens cycle times.
- Enhanced Productivity: Shortens setup times, thereby boosting productivity.
- Improved Safety: Simple operation enhances safety during use.

System Components
The active balancing system is ideal for turning operations involving asymmetric workpieces or small batch production of diverse product types.
