Workpiece
Inspection
Some workpieces are not suitable for grinding
on this sharpener.
Before grinding, inspect all
workpieces for the following:
• Hard Workpiece: Workpieces that are made
of stone, carbide, stainless steel, ceramics,
glass, or have hardened welds will wear out
most general-grade grinding wheels quickly.
If hard materials are to be ground, you must
install the correct type of grinding wheel.
•
Soft Workpiece: Workpieces that are made
of aluminum, brass, lead, and other nonfer-
rous metals will load up in the grinding wheel
and render the abrasive useless. Grinding
wood, plastics, rubber, fiberglass, or other
soft materials can also cause the same
problem and lead to the wheel overheating
and possibly bursting during use if ignored.
To restore a loaded grinding wheel surface,
redress with a dressing tool.
• Flexible/Unstable Workpiece: Grinding on
the side or the ends of cable, chain, or round
workpieces creates the hazard of workpiece
twist or grab, leading to entanglement with
the wheel or shaft. This hazard must be
avoided.
• Loose Parts: Make sure that the workpiece
is free of any parts like springs, pins, balls,
or other components that may loosen or dis-
lodge during grinding, and hit the operator.
• Strength: Make sure that the workpiece is
strong enough to be ground. Should it break,
the broken piece may dig into the wheel and
cause kickback or severe injury.
Typical Stropping Operation
The stropping function of the Model T32720 will
polish cutting edges and remove fine burrs left
after grinding.
To complete a typical stropping operation,
the operator does the following:
1. Examines workpiece to make sure it is suit-
able for sharpening.
2. Installs tool rest in horizontal position over
stropping wheel to sharpen with wheel
rotation.
3. Secures workpiece in tool jig (if necessary).
4. Applies light machine oil and abrasive honing
paste to stropping wheel.
5. Ensures ON/OFF switch is in OFF position
and connects machine to power supply.
6. Puts on personal protective equipment (PPE).
7. Stands aside, turns machine ON, and distrib-
utes honing paste on leather face of wheel
until it is evenly applied.
8. Rests workpiece (or jig, if used) against tool
rest and sharpens workpiece.
9. Stops machine.
