FerRobotics Active Contact Flange Kit ACF-K Review: Specs, Price and Applications

The FerRobotics Active Contact Flange Kit ACF-K/109/04 is designed for cobots. It provides up to 100 N push/pull over a 35 mm stroke, weighs 3.9 kg, runs on 24 V DC and mounts via a 50 mm ISO 9409-1 bolt circle.
Its modular design accepts interchangeable tools including 5 and 6 in random orbital sanders, a Jitterbug orbital sander, a belt file, die grinders, an angular die grinder and 4 and 5 in angle grinders, with minimal programming and almost no start-up time.
Quick Verdict
A plug-and-play finishing kit that turns a cobot into a versatile sanding and grinding station.

Design and Operating Principle
FerRobotics' patented Active Compliant Technology (ACT) is a pneumatic actuator with integrated sensors and fast control that keeps contact force constant regardless of robot position or part tolerances. The robot follows a nominal path while ACT compensates deviations, so programming effort drops and surface quality becomes reproducible.
Interchangeable tools let one cobot handle sanding, polishing, deburring, brushing and paint stripping.
Integration and Selection
Mount on a robot of suitable payload, connect power, clean dry air and extraction, and set force, speed and feed for each process step.
Program a nominal path; ACT compensates tolerances, reducing teaching effort.
