Operation.Overview
This machine will perform many types of operations
that are beyond the scope of this manual. Many of these
operations can be dangerous or deadly if performed
incorrectly.
The instructions in this section are written with the
understanding that the operator has the necessary
knowledge and skills to operate this machine. If at any
time you are experiencing difficulties performing any
operation, stop using the machine!
The overview below provides the novice machine operator
with a basic understanding of how the machine is used
during operation, so the machine controls/components
discussed later in this manual are easier to understand.
Due to its generic nature, this overview is NOT intended
to be an instructional guide.
To complete a typical operation, the operator does the
following:
1. Ensures workpiece is suitable for grinding.
2. Selects correct grinding wheel for operation,
inspects wheel, performs a "ring test," and installs
wheel.
3. Verifies/adjusts tool rest position so gap is
perpendicular and
