2. Product Overview
The Radially Compliant (RC) deburring tool, also known as Flexdeburr, is a robust, high‑speed and lightweightturbine driven deburring unit for deburring aluminum, plastic, steel, etc. with a robot or CNC machine. The RC
deburring tool is especially suited for removal of parting lines and flash from parts. However, its flexible design
allows it to be used in a wide variety of applications.
The RC deburring tool’s pneumatically controlled, articulated design allows the cutting bit to follow the part
profile and compensate for surface irregularities while maintaining a constant, settable force. This allows high feed
rates with uniform quality in any orientation. The tool also requires no oil, allowing clean exhaust air to be vented
directly into the work environment.
Compliance is supported by air pressure applied to the shaft of the unit and is used to perform consistent deburring
on irregular part patterns. The motor’s internal governor maintains high spindle speeds for optimum surface
finish. The RC deburring tool also utilizes standard industrial tungsten‑carbide bits which allows for adaptation tochanging assembly lines and part requirements.
The RC‑300 and RC‑340 series provides for (2) mounting types, a side mounting and an axial mounting. The side
mounting provides (2) locating dowel pins and (4) threaded holes. The axial mounting utilizes a tapered flange that
requires an adapter plate. Custom adapter plates for both side and axial mounting are available from ATI. Refer tohttps://www.ati-ia.com/Products/deburr/deburring_rc_main.aspx for more information.
The RC‑300 and RC‑340 series is equipped with a 3/8" Push‑to Connect fitting to supply the motor air (for ‑E
models ATI supplies an adapter from 3/8” to 8 mm) and a 5/32" (4 mm) Push‑to Connect fitting to supply thecompliance air.
A tool collet system secures the cutting bur. Many collet sizes and a various selection of tools are available toaccommodate a wide variety of applications.

2.1

Tool Collet Systems
All Flexdeburr products utilize removable collets to grip customer supplied cutting tools. Different collet
diameters may be substituted to retain numerous cutter shank diameters. The collet retaining nut is loosened
to open the collet allowing cutting tools to be removed and inserted. Once the tool or bur is set to the desired
depth, spanner wrenches are used to tighten the collet nut causing the collet to collapse and secure thecutting tool. The air motor design does not allow the installation of quick‑change or drawbar collet systems.
The standard tool holding system for Flexdeburr products is an economical, proprietary, single‑angle collet
design utilizing multiple gripping fingers. This is suitable for most applications where industry standard
shank diameter cutting tools are used and runout tolerances of up to 0.001” (0.025 mm) are acceptable.
Special sizes are available upon request but require custom machining.

2.2.2 Compliance Unit Performance
The graphs in Figure 2.2 illustrate the variation of compliance force with applied air pressure in thevertical orientation with the collet pointed toward the ground. Measurements may vary from one
product to another and should only be treated as nominal.
The actual force characteristics are dependent on mounting orientation and condition of the unit. In
applications, where the deburring tool is mounted horizontally, additional compliance air pressure
is required to overcome the weight of the motor. Compliance pressure is also dependent upon thematerial of the work piece, type of bur tool, and the amount of material that is removed.
The turbine motor attempts to maintain its full rated speed even under loaded conditions. However,when extremely heavy cuts are taken, the motor may eventually stall. Therefore, multiple, lightpasses are preferred over slow, heavy cuts.

Pneumatics
Connect the RC deburring tool as shown in the following figure.
Figure 3.3—Pneumatic Connections

WARNING: All pneumatic fittings and tubing must be capable of withstanding therepetitive motions of the application without failing. The routing of pneumatic lines must
minimize the possibility of over stressing, pullout, or kinking the lines. Failure to doso can cause some critical pneumatic lines not to function properly and may result indamage to equipment.
The air supply should be dry, filtered, and free of oil. A coalescing filter with elements rated for 5 micron or
better is required.
A high‑flow air pressure control regulator is required to supply the spindle motor at 6.2 bar (90 psi). A
second, precision, self‑relieving regulator supplies air for the compliance or centering force.
The compliance force is applied radially and is adjusted until the desired cut is made. The robot’s traversing
speed will also be adjusted to achieve the desired finish.
CAUTION: Pneumatic components used for the motor drive circuit must be capableof meeting the air consumption requirements (see Section 8—Specifications). Poor
performance will result if the correct components are not used.
Conventional, customer‑supplied, pneumatic components are used to control the air supply to the deburring
tool. ATI recommends that the user install a high‑flow pneumatic pressure regulator(ATI part number 9005-50-6166 or equivalent. See Section 8—Specifications for the maximum flow
requirements) and a high‑flow valve to properly supply a stable air supply of 6.2 bar (90 psi) to the spindle
motor. The RC deburring tool will not operate properly if supplied air below 6.2 bar (90 psi).
A second, precision, self‑relieving regulator (ATI part number 9005-50-6164 or equivalent) and valve areused to supply the compliance (centering) mechanism. This pressure corresponds to the side force on therotary bur. Because very little airflow is required for the compliance mechanism, a significantly smaller
valve can used (Consult the valve and regulator supplier’s literature when selecting these components).

Document #9610-50-1019‑09
If the complete work piece can be deburred with equal force, a conventional, manual pressure regulator
can be used for compliance. If the burrs to be removed vary from place to place on the work piece, andthis variation is repeatable for all work pieces of the same type, it may be necessary to adjust the force
using an analog pressure regulator controlled from the robot. Then analog output port in the robot or logic
controller is needed.
Solenoid valves are actuated from the robot or program logic controller by means of a digital output signal.

It is recommended that flexible plastic tubing be used for the motor air supply and the compliance force
air supply. The installed fittings can be removed to expose tapped supply ports thus allowing the useof alternate, customer‑supplied components. The turbine motor is extremely quiet and vents dry air tothe environment through the screen‑covered ports on the side of the housing. No mufflers are required.
Information on the sound intensity is provided in Section 8—Specifications. To reduce the sound from thecutting operation in neighboring working areas, a customer‑supplied barrier surrounding the installation may
be installed (Plexiglas® or Lexan® is preferred, see Section 8—Specifications).
The compliance force, air supply pressure regulator should have a 0‑4.1 bar (0–60 psi) range. Whentesting for the proper contact force, start with a very low pressure and increase slowly until the desired
cut is achieved.

4. Operation
These operating instructions are intended to help system integrators program, start up, and complete a robotic
deburring cell containing a deburring tool. The system integrator should be familiar with the task of deburring, in
general, and should have extensive knowledge relating to robots and automation incorporating robots.

4.1

Safety Precautions
DANGER: Never use the Flexdeburr for purposes other than robotic deburring. If usedin any other way, serious injury or damage to equipment may occur.
WARNING: All personnel, who are involved in operation of the RC deburring tool,
should have a thorough understanding of the operating procedures. Failure to follow
these procedures or neglecting safety precautions can create hazardous situations that
may injure personnel or damage the deburring installation and the RC deburring tool.
WARNING: Never operate the Flexdeburr product without wearing hearing protection.
High sound levels can occur during cutting. Failure to wear hearing protection cancause hearing impairment. Always use hearing protection while working in proximity ofthe deburring tool.
WARNING: Never operate the Flexdeburr product without wearing eye protection.
Flying debris can cause injury. Always use eye protection while working in the proximityof the deburring tool.
CAUTION: Do not use burs rated for less than the speed of the RC deburring tool
being used. Using lower rated burs may cause injury or damage equipment. Always
use burs rated for at least the speed of the RC deburring tool being used.
CAUTION: Do not use spare parts other than original ATI spare parts. Use of spareparts not supplied by ATI can damage equipment and void the warranty. Always use
original ATI spare parts.
CAUTION: Never be present near the deburring tool while it is started or in operation.
Flying debris and rotating parts can cause injury. If it is necessary to approach thedeburring tool while in motion, stand behind appropriate Plexiglas windows. Provide abarrier to prohibit people from approaching the deburring tool while in operation.
CAUTION: Never use or start the deburring tool without first reading and understanding
the operating procedures described in this manual. Never use the deburring tool for any
purposes, or in any ways, not explicitly described in this document. Using the deburring
tool without fully understanding the installation and operating procedures may cause
injury to personnel or damage to equipment. Mount the deburring tool and connect thepneumatic control equipment as described in this manual. Operate the deburring tool
as described in the manual.

4.2

Normal Operation
The following sections describe the normal operating conditions for RC 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 not receive proper air pressure, the tool stalls. Any
water in the system damages the housing and blades.

4.2.2 No Lubrication
Lubrication of any kind is strictly prohibited.
Turbine motors cannot have any oil in the motor air supply. Oil damages the speed regulator andcauses the motor speed to fluctuate out of tolerance.

4.2.3 Bur Selection, Design, and Maintenance
Use a carbide media.
RC tools have higher operating speeds and the media must be rated to at least the RC 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.
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 theoperating speed of the deburring tool. Operating the brush above its maximum rated speed can beunsafe due to unbalanced loading. Additionally, even balanced brushes can result in an excessive loadon the motor and reduced motor life.
Do not use a tool that results in axial loading on the RC 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 andpremature wear of the tool bearings and cutting bit. Additionally, collisions could result and createa 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 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 alonghigh 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 repeatability.

4.3

Flexdeburr Working Environment
As described in previous sections, the RCT-151 should only be used in conjunction with a robot in a secured
work cell/chamber.
The work cell must be secured by means of barriers to prohibit personnel from entering the cell. A lockable
door should be included as a part of the barrier in order to facilitate access to the cell for authorized
personnel only. The barrier could consist partly or fully of Plexiglas to facilitate observation of thedeburring operations.
During system or RCT-151 maintenance, make sure the RCT-151 and robot are stopped before entering therobot cell. When installing and testing, never be present in the cell when the RCT-151 is running.
Be aware of rotating parts. Use eye‑protection while working around the RCT-151.
Be aware of high sound levels. While the RCT-151 air motor is not loud, the cutting action associated withdeburring frequently is loud. Always use hearing protection while working in the neighborhood of thedeburring cell.
The RCT-151 should not be used to deburr materials that are prone to fracture. A fracturing work piece may
result in pieces of material damaging surrounding working environment and personnel. Material removed
correctly should be in the form of chips.

4.4

Tool Center Point (TCP) Position and Programming
Figure 4.1 shows the RC deburring tool dimensions. The Flexdeburr provides radial compliance andperforms best when the cuts taken are not excessively deep. The deburring tool spindle must never berunning while programming the robot. During teaching, the compliance air must be on and supplied above aminimum of 0.35 bar (5 psi).
Two programming methods are suggested, but others are possible. In the first method, a dowel pin ofsuitable diameter is inserted in place of a cutting tool (simulating the cutter shank diameter) when teaching
the robot path. For 6 mm collets, this will mean a 6 mm diameter pin of suitable length. The dowel pinshould extend sufficiently from the collet to reach the surface on the burr where cutting is desired (seeFigure 4.1). The diameter of the bur should not exceed that of the dowel pin by more than the compliance of
the RC deburring tool.
Another programming method is to teach the path using the center line of the bur as a guide, following
the edge of the part, and then manually or automatically adding offsets to the robot path points to achieve
the final correct burr path (see Figure 4.2). The programming method used will depend on the robot’s
capabilities and programmer preferences.

Document #9610-50-1019‑09
Figure 4.2—Flexdeburr Pointed Teaching Tool

Inside corners represent a complex situation for compliant deburring tools. In general, the bur must not
be allowed to simultaneously contact both perpendicular surfaces of an inside corner. The resulting force
imbalance in two planes will cause severe tool chatter. The customer is advised to create a tool path, which
will prevent the cutter from simultaneously contacting two perpendicular surfaces. A tapered cutter may
reach further into such an inside corner if the tool is presented in an inclined orientation and closer to the tipof the tool (Note: When working near the tip of a tapered cutter the surface cutting speed is reduced.)
When deburring inside radii, a similar situation may arise. The customer is advised that no attempt should
be made to deburr an inside radius less than 1.5 times the diameter of the desired cutter (Rmin = 1.5 x Cutter
diameter). Depending on the depth of cut, failing to follow these guidelines may result in excessive bur
contact that results in excessive tool chatter.
When running the robot program the first time, observe the path with the radial compliance air supply turned
down to approximately 0.35 bar (5 psi). When the robot path speed is increased, it is important to noticethat robot may deviate from the programmed path. Verify that at operational robot path speed, the bur isdeflected but contacts the work surface. Once the robot path has been confirmed, the compliance force of thebur should be adjusted, as described in Section 3.7—Pneumatics, in order to achieve a correct depth of cut.

4.5

Cutter Operation and Bur Selection
The RC deburring tool will perform best in “climb milling”. This refers to a bur whose directions oftraverse and bur rotation are the same. In the case of the RC deburring tools, the bur rotation is clockwise
when viewed from above. Climb milling would therefore involve clockwise motion around the part being
deburred. In climb milling, the heaviest cut is made as the tool enters the work piece and the chip becomesnarrower as the cut is completed. In “conventional milling”, the bur travels in a direction opposite of burr
rotation. This may aid in bur stability for some operations; however, the cutting edge of the bur is subjected
to higher friction and cutting forces. Tool wear is accelerated in this mode and surface finish quality will
generally be reduced. When “conventional milling”, extra care must be taken around corners. This poses a
potential hazard where the cutting force can deflect the bur causing the bur to break as the robot continues
along its path.
The selection of a bur is highly dependent upon the part’s material and geometry and the depth of cut. It is
not practical to present all the possibilities in this document. Please see
Section 4.5.1—Bur Selection for a short list of burs and suitable applications. It is worth mentioning herethat a specific family of burs is available for working with die cast alloys, aluminum, and plastics. Theseburs have fewer teeth and increased relief to minimize chip loading.
Plastics represent the most difficult deburring challenge due to the phenomenon of chip re‑welding. In thisprocess, if the bur is dull or the feeds and speeds are not correct for the material removed, the chip will melt
and weld to the bur or the work piece. This can quickly load a bur and produce unacceptable results. In
general, the traverse or feed rate of the deburring tool will be higher for plastics to minimize this behavior.
This results in larger cuts, which more effectively remove heat from the bur‑tool interface.

4.5.1 Bur Selection
Standard length commercial burs are used with Flexdeburr products. The length of these tools istypically around 2” for 1/4” shank diameter burs (50 mm for 6 mm diameter). Avoid longer shankburs that are available from industrial suppliers and that appear in their catalogs with descriptions
such as “long” or “extended” shank. Using extended or long shank burs in the Flexdeburr will placehigher loads and vibrations on the motor bearings resulting in reduced motor life. Bearing failurecaused by the use of extended shank burs is not covered under warranty.
CAUTION: Do not use long or extended shank burs with the Flexdeburr. Long
shank tools can lead to premature failure of the air motor and is not covered
under warranty.
ATI can provide guidance in bur selection; however, only experimentation will yield the results
desired. The following table is presented to assist in burr selection.
This following table is not comprehensive but includes many common bur types and burs
recommended for particular applications.

5. Maintenance
The RC deburring tool is designed to provide reliable service for long periods of operation. While simple in design,
there are few user serviceable parts in the assembly. The user is encouraged to return the unit to ATI for service.
Section 6—Troubleshooting and Service Procedures is provided to assist the user when they choose to service theunit in the field.
For all service, disconnect the air supply (before the solenoid valves). Drain any trapped air pressurein the lines. The air supply should be “locked out” to prevent accidental operation of the spindle.
During maintenance operations, refer to Section 6—Troubleshooting and Service Procedures formaintenance instructions. Service and repair parts are identified in Section 7—Serviceable Parts andhttps://www2.ati-ia.com/Products/deburr/deburring_rc_main.aspx.

5.1

Pneumatics
The air lines to the deburring tools should routinely be checked for their general condition and replaced
as required. The air to the Flexdeburr must be filtered, dry, and non‑lubricated. The air filters should bechecked and replaced as required to maintain optimum performance. The life of the filter elements isdependent on the quality of compressed air at the customer’s facility and therefore cannot be estimated.

5.2

Lubrication
Lubrication systems are not to be used. The Flexdeburr turbine motor must be supplied with clean, dry,filtered air. Oil in the air stream will cause the turbine motor to fail prematurely. Failure of the motor due
to oil in the air stream is not covered under the warranty. See Section 3.7—Pneumatics for details on air
supply and quality.
CAUTION: Do not use lubricated air with the Flexdeburr. Oil in the air stream will
result in the premature failure of the air motor and is not covered under warranty. It
is recommended that the customer use a coalescing filter and filter elements rated 5
micron or better.

5.3

Bellows Boot Inspection
The bellows boot prevents debris from entering the housing and protects internal components. Inspect
the spindle boot regularly for damage and replace if necessary. Refer to Section 6.2.5—Tapered Bellows
Boot Replacement.

5.4

Bur Inspection
The bur will wear depending on cut depth, feed rate, and material being deburred. Inspect the bur regularly
for wear, and refer to Section 6—Troubleshooting and Service Procedures for symptoms of a worn bur.

5.5

Spindle Motion Inspection
The pivot bearing allows articulation of the motor assembly. The pivot bearing is subject to wear and should
be replaced when excessive spindle motion is observed. Contact between the motor air supply fitting and themain housing indicates pivot bearing wear which should be corrected. Refer to Section 6.2.2—Rear Housing
and Pivot Bearing Replacement.

To minimize possible downtime, the pivot bearing should be replaced any time the turbine motor
is replaced. Early Flexdeburr units can be identified by their lack of radial and axial tapped holes
for the pivot bearing keying dowel (refer to Figure 6.3). During maintenance of these units thecustomer should replace the entire rear housing assembly to upgrade the deburring tool. The earlystyle of pivot bearing and rear housing are not currently supported.
The pivot bearing may be replaced in one of two ways. For quick repairs with minimal downtime,
the user is encouraged to replace the entire rear housing assembly. Refer to Section 6.2.2.1—Rear
Housing Replacement. When a spare unit can be placed into service or downtime is not an issue, anew pivot bearing can be installed in an existing rear housing assembly. Refer to Section 6.2.2.2—

9.1

Motor Life and Service Interval Statement
The air motors that are used in ATI deburring/finishing tools are subject to wear and have a finite
life. Motors that fail, during the warranty period, will be repaired or replaced by ATI as long as there
is no evidence of abuse or neglect and that the normal operating practices outlined in this manual
have been observed.
Components such as motor vanes, bearings, any gear reduction components, and collet nuts/chucks are
considered consumable and are not covered by warranty. The customer should expect to service or replacethese items at designated service intervals. For any part that is not detailed in this manual, contact ATI forpart numbers and pricing.
Premature bearing failure can occur from exposing the deburring tool to coolants and water or impacts fromcollisions. Other failure modes that are outlined in the manual and relate to improper machining practices
and deburring media selection.

9.1.1 Turbine Motor Products (Flexdeburr (RC) models)
Turbine motors are not serviceable at this time. The expected life of a turbine motor in normal
operation is entirely application dependent based on a multitude of factors. To maximize the lifeof turbine motor products, the customer should follow closely the normal operation guide in the
product manual. The supplied air must be totally lube free and filtered to remove particulates
and moisture. Exposing the turbine motors to oil in the air supply results in premature failure.
Premature bearing failure can occur from exposing the deburring tool to coolants and water or
impacts from collisions. Other failure modes are outlined in the manual and relate to impropermachining practices and deburring media selection.
