1.3 Safety Precautions
WARNING: Never operate the Flexdeburr product without wearing hearing protection.
High sound levels can occur during cutting. Failure to wear hearing protection can
cause hearing impairment. Always use hearing protection while working in the
neighborhood of the 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
neighborhood of the deburring tool.
CAUTION: Do not use burs rated for less than the speed of the RC deburring tool
being used. Using these too 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 spare
parts 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 the
deburring tool while in motion, stand behind appropriate Plexiglas windows. Provide a
barrier to prohibit people from approaching the deburring tool while in operation must
secure the installation.
CAUTION: Do not perform maintenance or repair on the Flexdeburr product unless the
tool is safely supported or docked in the tool stand and air has been turned off. Injury
or equipment damage can occur with tool not docked and air on. Dock the tool safely
in the tool stand and turn off the air before performing maintenance or repair on the
Flexdeburr product.
NOTICE: Turbine motors are not serviceable at this time. Refer to Section 10—Terms and
Conditions of Sale. To maximize the life of turbine motor products the customer should closely
follow the normal operation procedures outlined in the product manual. Refer to Section 4.2—
Normal Operation. The air must be totally lube-free and ltered to remove particulates and
moisture. Exposing the turbine motors to oil in the air supply results in premature failure.

2. Product Overview
The Radially Compliant (RC) Deburring Tool, also known as exdeburr, is a robust, high-speed and lightweight
turbine motor driven deburring unit for deburring aluminum, plastic, steel, etc. with a robot or CNC machine. The
exdeburr is especially suited for removal of parting lines and ash from parts. However, its exible design allows
it to be used in a wide variety of applications.
The exdeburr’s pneumatically controlled, articulated design allows the cutting bit to follow the part prole 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 nish.
The exdeburr also utilizes standard industrial tungsten-carbide bits which allow for adaptation to changing
assembly lines and part requirements.
The RC-151 series provides for two mounting types—side and axial mounting. The side mounting provides two
locating dowel pins and four threaded holes. The axial mounting utilizes a tapered ange that requires an adapter
plate. Custom adapter plates for both side and axial mounting are available from ATI. Refer to Section 9—Drawings
for more information.
The RC-151 series is equipped with (2) 1/8 NPT ports to supply the motor and compliance air (-E models are
equipped with (2) 1/8 BSPP ports).
A tool collet system secures the cutting bur. Many collet sizes and a various selection of tools are available to
accommodate a wide variety of applications. The RC-151 series is equipped with a 1/8’’ standard collet, (-E models
are equipped with a 3mm collet).

2.1 Tool Collet Systems
A collet system secures the bur to the tool. Various collet sizes are available to accomodate a wide variety of
applications.
All exdeburr 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 is set to the desired depth,
spanner wrenches are used to tighten the collet nut causing the collet to collapse and secure the cutting tool.
The turbine motor design does not allow the installation of quick-change or drawbar collet systems.
The standard tool holding system for exdeburr products is an economical, proprietary, single-angle collet
design utilizing multiple gripping ngers. 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 charts below illustrate the variation of compliance force with applied air pressure.
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 exdeburr tool is mounted horizontally, additional compliance air pressure
is required to overcome the weight of the motor. Compliance pressure is also dependent upon the
material of the work piece, type of bur tool, and the amount of material that is removed.
The turbine motor will attempt to maintain its full rated speed even under loaded conditions.
However, when extremely heavy cuts are taken, the motor may eventually stall. Therefore,
multiple, light passes are preferred over slow, heavy cuts.
