6. Troubleshooting and Service Procedures
For all service, the air supply (before the solenoid valves) must be disconnected. Drain any trapped air pressure in
the lines. It is suggested that the air supply be “locked out” to prevent accidental operation of the spindle. Refer to
Section 6.2—Service Procedures
for maintenance instructions. Service and repair parts are identified in
Section 7—
Serviceable Parts and Section 9—Drawings .
6.1 Troubleshooting
Deburring process development is an iterative, learning task. The following table is presented to assist in
solving deburring issues.
Table 6.1—Troubleshooting
Symptom Cause Resolution
Bur Wear
Hard work material Use better grade bur material, add coating (TiAlN).
Too heavy a cut Decrease width of cut/make multiple passes.
Feed rate is too slow Increase feed rate.
Bur Breakage
Too heavy a cut Decrease width of cut/make multiple passes.
Deflection at corner
Climb mill/Do not begin path at sharp corner.
Impacting part Decrease feed rate at contact/ enter part at an angle.
Unequal
compliance
Worn ring cylinder
Replace ring cylinder. Refer to Section 6.2.3—Ring
Cylinder Assembly Replacement .
Pivot bearing worn
Replace the pivot bearing. Refer to Section 6.2.4—Rear
Housing Assembly and Pivot Bearing Replacement .
Pivot bearing
components (axial,
radial, preload set
screw) are not set
correctly.
Reinstall the axial and preload set screw and verify
the preload set screw is correctly adjusted. Refer to
Section 6.2.4—Rear Housing Assembly and Pivot Bearing
Replacement
.
Poor finish on work
piece
Feed rate is too fast Reduce feed rate.
Bur is worn
Inspect bur. If worn, replace. Refer to Section 6.2—Service
Procedures
Motor bearings are
worn
Inspect the motor spindle shaft. If the shaft feels loose or
has play, replace. Refer to
Section 6.2.2—Turbine Motor
Replacement.
Bur is chattering
during cut
Feed rate is too fast Reduce feed rate.
Lack of rigidity Increase radial compliance pressure.
Too heavy a cut Decrease width of cut/make multiple passes.
Improper Bur selection
Choose bur designed for work material. Refer to
Section 4.5.1—Bur Selection .
Bur is worn
Inspect bur. If worn, replace. Refer to Section 6.2.1—Bur
and Collet Replacement .
Motor bearings are
worn.
Inspect the motor spindle shaft. If the shaft feels loose
or has play, replace the motor. Refer to
Section 6.2.2—
Turbine Motor Replacement.
