iv CBNdoc080917 Limitations
LIMITATIONS
When used within the limits of its design, this machine performs as a light-duty profile
grinder for Wood-Mizer blades. Do not use this machine for anything other than as
described below. Failure to acknowledge these limitations will lead to premature wheel
wear.
1. This equipment is designed for light-duty profile grinding of Wood-Mizer blades only.
2. This grinder cannot be used to convert the tooth profile more than would require a .020”
change in tooth height. Blades with 4° can be changed to 10° and vice-versa (may require
two or more light passes through the grinder). All other profile conversions should be
avoided.
3. Heavy grinding is not recommended. If necessary, grind twice to reduce the possibility of
premature wheel wear.
4. Approved grinding oil is required for proper performance and maximum wheel life.
