4.2.2 Lubrication
Lubricate the air supply with 1‑2 drops per minute of commercial air tool oil.
Vane motors for the RCV‑490 should be run with lubrication in the air supply to
maximize motor life.
4.2.3 Media Selection, Design, and Maintenance
Use carbide bits under 11/16" diameter and 2" in length
Do not use media that requires axial loading.
Do not use media that is rated below the RCV‑490 idle speed.
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.
In many robotic deburring applications, including steel and aluminum, no cooling or lubrication
of the rotary bur is necessary. For some materials and situations, the addition of coolants or
compressed air may aid the cutting process. If it is determined that liquid coolants are required, a
non‑oil, cutting type fluid should be used to prevent premature wear of the spindle bearing.
4.2.4 Deburring Tool Approach Path Should Be Slow and at an Angle
The RCV‑490 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 results in premature failing of the unit. 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 bur contacts the underlying material below the edge,
because axial loading results on the tool and bearings. This axial loading results in premature
failing of the unit.
Do not attempt to deburr to a depth of more than 30% of the diameter of the bur. Exceeding this
depth causes excessive chatter and could result in the following: premature bur wear, the motor
stalling, and damage to the bearings, the compliance ring, or both.
When deburring holes, interpolate the perimeter. Do not use a countersink tool because that tool
results in axial loading and premature wear of the bearings.
4.2.6 Program the Robot to Incorporate 50% Compliance Travel of the Tool
Program the robot to have the tool's compliance at 50% travel when on the nominal path.
As the part's edge deviates from the perfect path, the cutting bit can use compliance to follow along
high and low spots without losing contact or hitting the positive stop and gouging.
Do not "bottom out" the compliance and hit the positive stop.
Repeated impacts on the positive stop create slop in the compliance and reduce recentering.
