4.2 Normal Operations
The following sections describes the normal operating conditions for RS deburring tools.
4.2.1 Air Quality
The air supply should be dry, filtered, and free of oil. A coalescing filter with elements rated for 5
micron or better is required. The air must be supplied at 6.2 bar (90 psi).
Air quality affects tool performance more than almost any other factor. Particulate can block airflow
or impede vane motion. If deburring tools do receive proper air pressure, the tool stalls. Any water in
the system damages the housing and blades.
4.2.2 No Lubrication
No lubrication is required.
Turbine motors cannot have any oil in the motor air supply. Oil damages the speed regulator and
causes the motor speed to fluctuate out of tolerance.
4.2.3 Bur Selection, Design, and Maintenance
Use a carbide media.
RS tools have higher operating speeds and the media must be rated to RS idle speed at a minimum.
Check media quality regularly to ensure it is not dull or worn. Using worn media causes a poor
surface finish and increased wear on the bearings that results in premature tool failure.
Do not use shank extensions because the large moment loads combined with the high speed can be
dangerous.
Brushes are not recommended because the maximum rated speed of the brush is less than the
operating speed of the deburring tool. Operating the brush above its maximum rated speed can be
unsafe due to unbalanced loading. Additionally, even balanced brushes can result in an excessive load
on the motor and reduced motor life.
Do not use a tool that requires axial loading on the RS tool.
4.2.4 Deburring Tool Approach Path Should be Slow and at an Angle
The deburring tool should approach the workpiece slowly and at an angle.
When beginning a deburring pass, try to minimize the initial impact on the work piece by slowly
approaching the tool at an angle while maintaining a slightly parallel path with the surface.
If the tool quickly approaches perpendicularly to the workpiece, the result is gouging and premature
wear of the tool bearings and bur. Additionally, collisions could result and create a hazardous situation
for both personnel and equipment.
4.2.5 No Axial Loading
Do not apply axial loads that are parallel to the axis of the tool’s rotation.
Do not deburr shallow edges where the cutter contacts the parent material below the edge; otherwise,
axial loading is applied on the tool and bearings and results in premature failing of the unit.
When deburring holes, interpolate the perimeter. Do not use a countersink tool; otherwise, axial
loading occurs and causes premature wear on the bearings.
4.2.6 Perpendicular Loading
Do not apply radial loads that are perpendicular to the axis of pivot. Always keep the tool pivoting
perpendicular to the deburring surface. Loading the tool along the pivot axis will damage the pivot
pins and cause premature failure.
