High-speed deburring machine with integrated Axial Compliance

Speedeburr is a family of deburring and chamfering tools especially developed for robotic edge deburring. The tools have integrated control of the contact force. The Hiac Speedeburr 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.

The Hiac is suited for light and medium effort deburring of burrs produced by machining operations on objects made of aluminum, steel, and other materials and burrs on die-cast objects, fiber-reinforced plastics, etc. 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 Hiac is designed to take care of just that inaccuracy, so that the final deburring result will not be influenced.

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

The patented force control principle provides a very high stiffness in the path direction, and a low stiffness in contact force direction. In combination with the 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 Hiac. The Hiac uses a conical shaped tool, with axial force control. Compared to common cylindrical shaped robotic tools, the Hiac will greatly reduce robot programming time as well as cycle time. Few parts means a sturdy design and long life.
