OPERATING INSTRUCTIONS
GRINDING INFORMATION
It may be necessary to run the glass through the edger more than once. The
number of “passes” through the edger for grinding a specific edge is dependent
upon four factors:
1)
Grit and type of the grinding wheel
2)
Depth of grind
3)
Smoothness of finished edge
4)
Size of rough-cut flares
Multiple “passes” may also indicate that the diamond wheel may have loaded up
with glass grinds, glazed over, or wore the diamond matrix below the surface of
the bonding material. See the “Maintenance” section.
Grit of the diamond wheel is very important to the ease of grinding. The coarser
the grit, the easier the wheel will edge. However, coarse grit wheels will leave
rough edges with chips. Conversely, fine grit wheels make a smooth cut, and do
not remove as much glass per pass.
The amount of glass that must be removed is another important consideration.
For the longest wheel life, the smallest amount of glass possible should be
removed utilizing more passes or a slower conveyor speed. The cut of the glass
edge determines the amount of glass to be removed. If the cut edges are
straight, without flares or protrusions, then the amount of glass to be removed is
minimal. If the cut edges are jagged and uneven, a greater amount of glass will
have to be removed.
The correct amount of passes, conveyor speed or depth of cut for the desired
edge will have to be determined for each thickness of glass. Through
experimentation, the combination that gives the desired results should be
documented so that the procedure can be duplicated at a later date.
OPERATION
ADJUSTMENTS
1)
Set the grinding (or polishing) wheel to the proper setting for the thickness
of glass to be ground. (See “ADJUSTMENT OF GRINDING (POLISHING)
WHEEL” in Section 4.)
2)
Adjust height of wheel for desired depth of cut (see Section 4).
