BEDKNIFE GRINDING
--POSSIBLE CAUSE--
--REMEDY--
--REASON--
--PROBLEM--
A--Grinding wheel rim is not
completely over the top face
being ground.
B--Gib screws loose, or
carriage infeed screw loose.
Grinding head is traversing too
fast.
A--Gib screws loose, or
carriage infeed screw loose.
The top face of
the bedknife is
ground unevenly
across the width.
Too coarse a
grind on bed-
knife.
The amount of
stock removed
varies when
traversing in
opposite
directions.
When the rim doesn't
extend over the top face, it
wears unevenly and causes
grooves across the bed-
knife.
A loose gib, backlash in
infeed screw, or grit buildup,
allows grinding head to
move when grinding.
Traversing speed controls
the grinding surface texture.
A slower traverse produces
grind marks closer together.
A loose gib, backlash in
infeed screw, or grit buildup,
allows grinding head to
move when grinding.
The wheel rim must extend
over the bedknife top face by
1/2" [13 mm] whenever
possible. See Operators
Manual. If not possible, dress
the wheel more often.
Tighten gib screws to prevent
movement (see Page 23).
Also check for any grinding grit
buildup behind the gib.
Eliminate backlash in
horizontal handwheel (see
Page 24).
Slow down the traversing
speed to 12 FT/MIN.
Tighten gib screws to prevent
movement (see Page 23).
Also check for any grinding grit
buildup behind the gib.
Eliminate backlash in
horizontal handwheel (see
Page 24).
