Edge rounding

If an edge rounding is required in addition to the deburring process, a defined and constant edge rounding can be achieved with the ATB® brushes with abrasive nylon.

In contrast to deburring with wire, the abrasive grains embedded in the plastic fibers work against the workpiece edge with rotation and feed and round it off. Different rounding sizes can be achieved by changing the setting parameters.

Edge rounding is used on a wide variety of workpieces. The determining requirement for the filleting can also be as varied.

Possible objectives of the geometric modification of the component may include:

• Safety aspect: reduction of the risk of injury from cuts
• Hygiene aspect: ease of cleaning the surface
• Reduction of tool wear: rounding of cutting edges to increase tool life
• Preparation for subsequent surface coating: Geometry enables more uniform layer thicknesses and reduces the risk of corrosion on thin-walled components

The following is a list of practical examples where edge rounding can be achieved with the aid of technical brushing solutions:

• Tools (e.g. cutting tools such as drills)
• various milled and turned parts
• workpieces made of sintered metal
