GRINDING WHEELS
The use of accessories and attachments not
recommended by DELTA
®
may result in a risk of injury. Grinding
wheels used with this grinder should be rated for 3,400 RPM or
higher and have a width of 3/4 inch for the 6 inch grinder, and 1
inch for the 8 inch grinder. Grinding wheels for the DELTA
206 must be 6 inch in diameter with a 1/2 inch arbor hole.
Grinding wheels for the DELTA
with a 5/8 inch arbor hole.
Using a wheel that is less than 3/4 inch wide for
the 6 inch grinder, or 1 inch wide for the 8 inch grinder, will cause
vibration and could damage the machine.
ALWAYS maintain a distance of 1/8 inch or
less between the grinding wheel and both the tool rest and the
spark shields. Adjust the tool rests and spark shields as the
grinding wheels decrease in size with use.
DRESSING THE WHEELS
Your DELTA
®
23-206 (6 inch) Grinder or 23-207 (8 inch) Grinder
come with a diamond-based wheel dressing tool included. There
is on-board storage for the wheel dressing tool at the rear of the
machine for easy access. Use this tool or any other suitable stick-
type wheel dressing tool to keep your grinding wheels clean and
square.
To dress the wheel, refer to Figure 7 and do the following:
1.
Bring the wheel dressing tool
rest until it just touches the high point on the face of the
wheel.
2.
Dress the wheel by moving the wheel dressing tool back
forth.
3.
Repeat this operation until the face of the grinding wheel
is clean and the edges are square.

For best results, and to properly maintain the grinding wheels,
follow these recommendations:
1.
KEEP the wheels properly dressed.
2.
DO NOT force the work against a cold wheel. Always run
the grinding wheel for one full minute before applying a
workpiece to it.
3.
Use ONLY balanced wheels with your grinder. Using
balanced wheels adds years to the life of the bearings on
the grinder. By eliminating the most common source of
vibration, your grinding projects will be more accurate.
