Troubleshooting Bedknife Grinding
Perform this troubleshooting procedure is a newly ground bedknife does not cut
test paper at the center of the knife.
1. Place a .002 inch shim (Part No. 140-5531) between the outer most left
and right magnets and the bedbar-bedknife assembly when placing it in the
grinder (
Figure 107 ).
Note: If a bedknife does not cut paper more than 2 inches from each end,
place the shims on the inner magnets instead of the outer magnets.

1. 1 inch between the outer edge of the
bedknife and the outer magnet 3. Inner magnets
2. Outer magnets 4. .002 inch shim (Part No. 140-5531)
2. Ensure that you are following the grinder manufacturer instructions and grind
the bedknife.
3. In most cases the outside of each outer magnet should be 1 inch (25 mm)
from the outside edge of the bedknife.
4. Remove the bedbar-bedknife assembly from the grinder.
5. If you have a precision flat granite surface plate, check the bedbar-bedknife;
refer to Checking the Bedknife on a Granite Surface Plate (page 7–17) .
6. Install the bedbar-bedknife assembly to the cutting unit and adjust the cutting
unit; refer to your Cutting Unit Operator's Manual.
7. Test the cut across the entire length of the bedknife, if the paper does not cut
across the entire length, complete this procedure again with an additional
shim installed on each magnet (maximum of 4 shims total).
Note: If a properly adjusted cutting unit does not cut the test paper cleanly
across the entire length of the bedbar-bedknife after grinding, check the grind
angle to be sure it is ground to the bedknife grinding specification; refer to
Bedknife Grinding Specifications (page 7–14) .
Note: If there are still gaps after grinding with 2 shims at either the outer or
inner magnets (maximum of 4 shims total), there may be a separate issue;
contact the Technical Assistance Center.
