Deburring of Sintered Powder Metal Parts
The deburring of PM parts is commonly performed in a batch
This typically involves loading
a quantity of parts into a vibratory
bowl filled with abrasive media.
The vibration of the bowl causes
the abrasive media, and parts,
to "flow". This interaction
between the media and parts
gradually abrades all surfaces
of the part.
Drawbacks to this process
include part impingement
upon one another, waste generation, lodging of media into the part,
deburring of unnecessary areas
on the part and the inherent
vibration and noise created by the operation of these systems.
This paper discusses an abrasive
filament medium which is ideal for
deburring and edge radiusing PM parts.
When formatted into a brushing tool, it can be applied on machine based systems for semi-automated
or fully automated deburring
of PM components.
Through proper application, it is possible to gain the advantages
of productivity, quality, and economics without the negatives associated
with alternative methods.

Sintered Powdered Metal
Challenge: Customer is a large automotive parts supplier and needed to remove burrs left by a double disc grinding operation.
Current process: This customer had an older piece of brush deburring equipment that was frequently down for repairs and with part production increasing it could not be relied upon.
