MECHANICAL TROUBLESHOOTING (Continued)
PROBLEM-- Uneven traverse speed or grinding
stock removal from reel is irregular.
Possible Cause
Linear bearings are damaged or have grit buildup
causing uneven traversing load.
Grinding shaft or wheels have grit buildup causing
uneven loading.
Left side traverse pulley is full of grit causing the
pulley not to turn freely on shaft.
PROBLEM--Traverse Belt Slips
Possible Cause
Clamping tip is not adjusted properly.
Too heavy a grind for traverse speed.
PROBLEM-- Too heavy a burr on cutting edge
of reel blades.
Possible Cause
Traverse speed set too high causing a heavy burr
on the reel blade when spin grinding.
PROBLEM--Cone shaped reel after grinding.
Possible Cause
Grinding head travel not parallel to the reel center
shaft.
PROBLEM--Relief grind on the reel blades do
not go the full length of the reel.
Possible Cause
Need to adjust the finger stop.
Need to dress the Wheel to the correct angle
Checkout Procedure
Clean shafts and bearings according to the lubrication
of Grinding Shaft and Linear Bearings instructions in
the Maintance Section of the manual. If problem
persists replace linear bearings according to the
replacement of linear bearings instructions.
Clean the wheel flanges and shaft (see Lubrication of
Grinding Shaft). Replace flanges or shaft if
necessary.
Clean and lubricate the shaft and pulley.
Checkout Procedure
Adjust the clamping tip as specified in the Traverse
Clamp Force section of this manual.
Slow the traverse speed or back off on the amount
that is being infed.
Checkout Procedure
Traverse speed should be set lower approximately 12
ft./min (4 meters/min.) for a smaller burr on the cutting
edge.
Checkout Procedure
Grinding head travel was not setup parallel to the reel
center shaft in vertical and horizontal planes. See
Align the Reel Section.
Checkout Procedure
Adjust finger stop and check for contact full length.
Dress the wheel (For more detail, see relief grinding
section in operating instructions of the manual.)
