NACHI SRA166/210-01A SPOT WELDING Robotic Arm

  • Robot motion makes minimum cycle times unbeatable. Light weight and high rigidity design results in high acceleration and minimum vibration. Maximum speed on all axes reduces move time. All this provides dramatically improved productivity
  • Industry leading advanced servo gun software features and technologies
  • Improved drives and motors for accurate positioning and better repeatability
  • Power consumption reduced 15% from existing models by reducing the robot’s weight by 20% and using cutting edge motor drive controls
