6.4 Replacement of Burrs
Burr Replacement
The Figure shows the burr-changing tools, the Compensation
piston and burr (rotary file). The Compensation piston and the
Cylinder should be inspected whenever a burr is replaced. The
Compensation piston should rotate freely (by hand) in the Cylinder
with no binding. If binding is detected, the Compensation piston
and/or Cylinder should be replaced
Regular Operational Maintenance
To change the burr, unscrew it with the burr-changing tools and
replace it with a new one. Re-assemble the parts
Regular Operational Maintenance
After the burr is changed and the unit re-assembled, check that
the Compensation piston is rotating with the burr. If the
Compensation piston is not rotating, static friction may be
interfering so that the axial force cannot remain constant. In that
case, clean the Compensation piston and inspect for any visible
scratches. If a burr with an imbalance is used, the Compensation
piston may also stop rotating. All burrs are checked for imbalance
before they are shipped.
Only original SCHUNK burrs should be used.
