9.0 Operation
A bench grinder is designed for hand-grinding
operations such as sharpening chisels,
screwdrivers, drill bits, removing excess metal, and
smoothing and polishing metal surfaces.
Always use approved safety
glasses or face shield while operating tool.
Failure to comply may cause serious injury.
The IBGB Grinder/Sander offers multiple working
methods:
Grinding wheel – A medium-grain, 36-grit wheel is
provided, and is effective when a considerable
amount of metal must be removed, or when
obtaining a smooth finish is not important. A finer
grain abrasive grinding wheel (not provided) can be
mounted for sharpening tools or grinding to close
size tolerances because it removes metal more
gradually for precision grinding and achieves a
smoother finish.
Belt and platen (horizontal or vertical position) –
Workpieces of any length can be worked on the belt
and against the platen. The table or tool rest should
be tightened in place and used to support the
workpiece. The table can tilt down to 45-degrees,
and may also be used as a fence for workpiece
support when sanding arm is horizontal.
The general-purpose 80-grit sanding belt is useful
for many applications, including radiusing, deburring
and finishing/polishing of both ferrous and non-
ferrous alloys.
Contour sanding (horizontal position) – Contoured
workpieces can be sanded over the drive wheel.
Open end cover, adjust tool rest and tighten in
place.
