Straight High-speed deburring tool with Integrated Axial Compliance

The AC-180  is suited for light and medium effort deburring of burrs produced by machining operations on objects made of aluminium, steel and other materials, and burrs on die-cast objects, fibre- reinforced plastics, etc. The AC-180 consists of an air driven vane motor and a rotary file. The file is free to move 8mm in axial direction, by use of remote controlled air pressure.

In every practical application of industrial robots there will be a deviation between the burr edge and the programmed path. This is due to object tolerances, fixture tolerances, and dynamic robot path inaccuracies. The AC-180 is designed to take care of just that inaccuracy, so that the final deburring result will not be influenced.

The AC-180 is air driven, to take advantage of the low weight and low volume of air vane motors compared to their power output. One of the most important features of the AC-180 is its ability to reach burr edges with difficult access, such as internal burrs.

The patented force control principle gives a very high stiffness in the path direction, and a low stiffness in contact force direction. In combination with a low weight of the suspended system, this avoids chattering and vibrations.

The life length of the 16 mm diameter rotary tungsten carbide files is proven to be extended by use of the AC-180. The tool uses a conical shaped tool, with axial force control. Compared to common cylindrical shaped robotic tools, the AC-180 will greatly reduce the robot programming time and cycle time. Few parts mean a robust design and long lifetime.
