WARNING: To Avoid Serious Injury And Ensure Best Results for Your Application, Please Read Care-
fully All Operator and Safety Instructions provided for your DeBurr-Z, as well as all other safety instructions that are
applicable, especially those for your machine tool.
1.Proper Clothing: the rotating spindle of a machine tool can snag loose fitting clothing, jewelry or long hair. Never
wear jewelry, long sleeves, neckties, gloves or anything else that could become caught when operating a machine
tool. Long hair must be restrained or netted to prevent it from becoming entangled in rotating spindle.
2.Proper Eye Protection: Always wear safety glasses with side shields to protect your eyes from flying particles.
3.Proper Work Piece Fixturing: Never hold the work piece or the vise it is held in, by hand. The work piece must
be clamped firmly to the table of the machine so that it cannot move, rotate or lift.
4.Always Be Aware Of The Potential Hazards Of A Machining Operation: sometimes working with your ma-
chine can seem routine. You may find that you are no longer concentrating on the operation. A feeling of false se-
curity can lead to serious injury. Always be alert to the dangers of the machines with which you work. Always keep
hands, body parts, clothing, jewelry and hair out of the areas of operation, when the machine spindle is moving.
Areas of operation include the immediate point of machining and all transmission components including the debur-
ring tool. Never bring your hand, other body parts or anything attached to your body into any of these areas until the
machine spindle is completely stopped.
5.Be aware of any other applicable safety instructions / requirements
_____________________________________________________________________________
CHECK LIST FOR GOOD DEBURRING.
1. Never use this deburring tool before reading all safety instructions for this tool, as well as the machine it
is to be used on.
2. Is the tool correctly inserted into the holder/collet and secured?
3. Is the force setting adjusted correctly? See instructions.
4. Is machine feed correct?
5. Has the tool length been correctly defined?
6. Is work piece held rigidly against rotation and upward movement?
7. Have possible collision areas been checked and eliminated?

All-in One Overview
Advantages, Function and Characteristics
The DeBurr-Z deburring tool is an axially (Z axis) floating
tool holder, for use on CNC machines, designed for deburring
or chamfering the sharp edges of a work piece. The floating
holder allows the burr cutting tool to follow the edges of the
part even when these are not clearly defined or vary in posi-
tion like in the case of castings, cross holes or intersecting
surfaces.
The DeBurr-Z compensates in both the compression and the
extension direction allowing you to deburr both the top edges
and underside edges of the work piece.
There are 10mm of both compression float and extension float
and the force exerted against the work piece edge can be ad-
justed for harder work piece materials or to increase the size
of the edge break.
The force adjustment works equally and simultaneously in
both the compression and extension direction and making an
adjustment does not effect the tool length.
Neighboring tools and collision areas in the machine’s tool
magazine will normally not pose a problem thanks to the com-
pact design.
Maximum recommended speed is 10,000 RPM.
The feed rate can be programmed based on the material, and
the desired edge break size and finish.
Using external flood coolant / lubrication, results in the longest
tool life and best finish.
Burr cutting tools with angular
and spherical profiles can be
used, like the examples
shown here.

Burr Cutting Tool Recommendations
Burrs made from High Speed Steel, or Carbide, with angular or spherical profiles are recommended. A
variety of tooth patterns are available from different manufacturers. The tooth pattern influences the
finish, and metal removal rate and some patterns may be designed to work best in certain types of
materials.
For spherical
profiles, to allow
axial floating,
please avoid
using the side of
the burr cutting
tool.
Please note that
the DeBurr-Z floats
only in compres-
sion and extension.
It does not com-
pensate in the radi-
al or angular direc-
tions. We recom-
mend a 90° includ-
ed angle for producing
a 45°chamfer.
Avoid using side of tool
55°
55°
Please note that the DeBurr-Z
floats only in compression and
extension. It is not able to climb
very abrupt, or steep contours.
Programming a Z axis movement is
needed when climbing steeper
incline surfaces
Please use caution to avoid
contacting the work piece with
the edge or side of the cutting
tool.
Select a Burr Cutting tool with an
included angle that avoids side
contact.

the distance from this diameter to the

Programming and Applications
Program Diameter and Point Length, Initial Clearance Plane and Deburring Plane:
The deburring tool can be programmed similarly to other types of milling tools. As a first step it is helpful
to determine a diameter for the area on the cutting tool you would like to use in the program and the
length to the end of the tool from this diameter.

Adjusting the Force:
The spring force for both compression and extension can be adjusted simultaneously and equal-
ly by turning the sleeve. There is a scale for reference with setting 0 being the lightest force and
setting 6 the highest.
Floating over surfaces with height variation:
When floating over edges that vary in height , using
lower force settings will result in the most consistent
edge break.
Seng 0
Seng 6
Factors that influence the size of the edge break:
• Increasing the force setting will increase the edge break
• Increasing the compression or extension distance into the work piece will increase the
edge break.
• Reducing the feed rate will increase the size of the edge break.
Factors that influence the finish:
• Higher Spindle Speed improves the finish.
• Slower feed rates will improve the finish.
• Taking a second pass around the part can also improve the finish.
• The tooth pattern of the cutting tool can also influence the finish. A finer tooth pattern
can improve the finish but some materials like aluminum may cause the cutting tool to
load up with material if the tooth pattern is too fine.
• Using coolant lubrication will improve the finish and cutting tool life.

Entering and exiting from the part:
When the deburring tool enters or exits the work piece to begin cutting, there can be a larger
edge break at these locations. This can be minimized in several ways.
For top edge deburring
enter and exit at the
lowest point.
For underside edge
deburring enter and
exit at the highest
point.
Always approach the part in a Z axis plane. If you move the cutter sideways into the part in the
X,Y axis plane, it will cut more material as it climbs onto the edge.

Entering and exiting from the part:
When the deburring tool enters or exits the work piece to begin cutting, there can be a larger
edge break at these locations. This can be minimized in several ways.
Use rapid approach or a fast feed rate to enter or exit the cut from your clearance plane.
This minimizes the cycle time and also the size of the edge break at this location.
Z

or
G1 F10000.
Using a fast feed rate may be better than
rapid depending on the reaction time of the
machine.
Feed rate suggestion shown in mm
(10,000mm/min = 400 in/min)
We recommend using G64, to eliminate ex-
act stop, to improve the machine’s reaction
time between approach, cutting and exiting
movements.
Z
Another option is to use a fast feed rate to ramp into the part from the clearance plane.
This also helps to minimize the entry point. Similarly ramping out of the part from the cut-
ting plane to the clearance plane helps to minimize the edge break at the exit point.
Making a finishing pass is one more way to reduce the appearance of a heavier edge break
at entry and exit points.
