Frequently, deburring is a mandatory step in the production cycle of a metal part.
This process removes burrs formed during machining, injection or molding for reasons of safety, esthetics, or as required for the next manufacturing process. It also creates chamfers or rounded edges that improve the fatigue strength of certain parts.
In many industries, this process is still often performed manually as deburring quality depends on the operator’s skill and dexterity. It is, though, a particularly arduous task, that exposes operators to dust and requires the use of several different tools or abrasives.
GEBE2 deploys robotic solutions that reproduce an operator’s gestures and meticulousness using abrasives or cutting tools. Combined with a compliant device or using the natural compliance of the abrasives, the robot embeds rotary and linear effectors that attain execution speeds or forces that would be impossible to apply manually.
To enhance the autonomy and performance of their cells, GEBE2 has equipped its robots with systems that change effectors, sanding or cutting tools automatically.
The quality of robotic deburring, chamfering or edge-rounding is strongly related to the regularity of the tool’s motion on the part. This is ensured by our offline programming software (OLP), which creates and simulates all possible tool trajectories.
Optical measurements are used to locate areas where rough zones (forging, molding, etc.) and machined zones intersect in order to deburr or round off edges whose position cannot be repeated from one part to the next. This system can also be used to recognize parts or to check post-operation chamfer or edge-rounding performance.

The application is designed to remove the burrs that make parts dangerous to handle, and also to round off sharp edges. This result is achieved by selecting and using abrasives that are applied with a motor spindle that sweeps across all the profiles. The tool trajectory strategy combined with the abrasive’s natural compliance gives the expected result in terms of dimensions, regularity of shape and cycle time.
The deburring of irregular areas is often a tedious operation that generates non-quality. The purpose is to remove machining burrs while creating a chamfer without altering useful surface areas.
