Suhner's Robotic Compliance System Provides Compact Operation

Suhner’s fully electric EFC-02 compliance system provides precise, constant force throughout robotic grinding, sanding and deburring processes.

The EFC-02 connects a grinding machine — angle grinders, orbital sanders, angle polishers, straight grinders and others — to the robot, and it is designed to provide compact, fully electric operation.

The EFC-02 can be used for material removal or surface finishing even in tight or narrow spaces often found when processing stainless tanks and vessels for the food and pharmaceutical industries, or fiberglass bathtubs and sinks. The all-electric technology enables high-frequency measurements to monitor force and acceleration throughout the process. An advanced control algorithm then dynamically adjusts force and automates grinding processes based on pre-programmed parameters.

Suhner engineered the EFC-02 to provide users with simple robot programming for setting up even complex processes using an intuitive web-based interface or Fieldbus communication. This includes defining target force, payload and stroke values. EFC-02 features a visual LED indicator that informs users whether the grinding wheel is in contact with the surface or not, and when the stroke is at 50% to ensure maximum compensation, among other operational information. The EFC-02 also lets users know when maintenance is needed.

The end-of-arm EFC-02 active compliance system is fully compatible with Suhner’s end effectors, including angle grinders, orbital sanders, angle polishers and straight grinders. Optional automatic changers for abrasives or belts, which integrate easily with the EFC-02, are also available. By storing and dispensing new abrasives for pickup by a sander, these automatic changers effectively help speed processes and increase productivity.
