MAINTENANCE

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 3600 RPM or higher and have a width of 1" . Grinding

wheels for the DELTA

23-198 must be 6" in diameter

with a ½" arbor hole. Grinding wheels for the DELTA

23-199 must be 8" in diameter with a 5/8" arbor hole.

Using a wheel that is less than ¾"

wide for the 6 in. grinder, or 1" wide

for the 8 in. grinder, will cause vibration and could

damage the machine.

ALWAYS maintain a distance of 1/8" or

less between the grinding wheel and the

tool rest. Adjust the tool rests and spark guards as the

grinding wheels decrease in size with use.

FIGURE 8

DRESSING THE WHEELS

The DELTA

23-198 comes with one 6" aluminum oxide

grinding wheel (gray) and one 6" composite grinding

wheel (white). The DELTA

23-199 comes with one

8" aluminum oxide grinding wheel (gray) and one 8"

composite grinding wheel (white). 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.

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.

Your DELTA

23-198 (6 in.) Grinder or 23-199 (8in.)

Grinder come with a diamond-based wheel dresser

included. There is on-board storage for the dresser at

the rear of the machine for easy access. Use this tool

or any other suitable stick-type dresser to keep your

grinding wheels clean and square.

To dress the wheel, refer to Figure 8 and do the

following:

1. Bring the dresser (A) forward on the tool rest until it

just touches the high point on the face of the wheel.

2. Dress the wheel by moving the dresser back forth.

3. Repeat this operation until the face of the grinding

wheel is clean and the edges are square.
