Nachi SRA100H/SRA133HL Spot Welding Robots

Manufacturer: NACHI
Model: SRA100H/SRA133HL
Features
Smart Cable Management
Spot welding cables and utility lines are routed through the hollow forearm and wrist for protection, ensuring long life. No surprises from swinging dress cables not modeled in simulation. Minimize interferences, much better than external dress solutions.
World’s Fastest Robot
The best motion control in the class makes cycle times unbeatable. Light weight, highly rigid design robot for high acceleration with minimum vibration. The high speed of all axes provide minimized movement times. Dramatically improves manufacturing productivity.
Controller
FD12
