Burrs occur on sintered parts before and after the sintering process. Their removal is critical to the functionality of the workpiece.
Burrs occur on sintered metal workpieces before and after the sintering process. It is important to remove the burrs as that is the only way to ensure the functionality and fit of the workpiece.
The process typically involves two steps:
Burr Class 1: Tinsel Burr
Usually caused by fine grinding, flitter burrs are very small, with minimal connection to the workpiece. They are very easily removed.
Burr Class 2 - Small Burr Base
Small burr bases occur during grinding and are larger than tinsel burrs. These burrs are connected to the workpiece and must be removed mechanically.
Sintered workpieces are usually deburred in throughfeed systems with planetary head drive, in robot cells, brushing cells, or directly in machining centres.
Usually, disc brushes or round brushes with abrasive grit are utilised for deburring sintered parts.
Osborn's ATB® deburring tools are best suited for deburring sintered workpieces. A wide range of fill materials is available, such as silicon carbide, aluminium oxide or ceramic. There are different grit sizes and filament diameters. The arrangement of the fill material can also be adapted variably to the individual application.
