Mounting and Using Depressed Center Grinding Wheels and Sanding Flap Discs

MOUNTING AND REMOVING HUBBED WHEELS

Hubbed wheels install directly on the 5/8"–11 (B3) & M14 (AR, B2, B2C, BR threaded spindle.

1.Thread the wheel on the spindle by hand, seating the wheel against the soft mount.

2.Depress the spindle lock button and use a wrench to tighten the hub of the wheel.

3.Reverse the above procedure to remove the wheel.

CAUTION: Failure to properly seat the wheel against the soft mount before turning the tool on may result in damage to the tool or the wheel.

1. Install the metal backing flange (O)

on

E

spindle (E) against the soft mount.

2. Place wheel against the backing flange, centering the wheel on the backing flange pilot.

3. While depressing the spindle lock button, thread the clamp nut (P) on spindle, P piloting the raised hub on clamp nut in the center of grinding wheel.

4.Tighten the clamp nut with a wrench.

5.Reverse the above procedure to remove the wheel.

SURFACE GRINDING WITH GRINDING WHEELS (FIG. 9)

1.Allow the tool to reach full speed before touching the tool to the work surface.

2.Apply minimum pressure to the work surface, allowing the tool to operate at high speed. Grinding rate is greatest when the tool operates at high speed.

3.Maintain a 20° to 30° angle between the tool and work surface.

4. Continuously move the tool in a forward FIG. 9 and back motion to avoid creating gouges

in the work surface.

5. Remove the tool from work surface

 

 

 

 

before turning tool off. Allow the wheel to

 

 

20˚–30˚

stop rotating before laying the tool down.

 

 

 

 

EDGE GRINDING WITH GRINDING WHEELS (FIG. 10)

WARNING: Wheels used for cutting and edge FIG. 10 grinding may break or kickback if they bend or

twist while the tool is being used to do cut-off work or deep grinding. To reduce the risk of serious injury, limit the use of these wheels with a standard Type 27 guard to shallow cutting and notching (less than 1/2" [13 mm] in depth). The open side of the guard must be positioned away from the operator. For deeper cutting with a Type 1 cut-off wheel, use a closed Type 1 guard. Refer to pages 62–64 for more information.

1.Allow the tool to reach full speed before touching the tool to the work surface.

2.Apply minimum pressure to the work surface, allowing the tool to operate at high speed. Grinding rate is greatest when the tool operates at high speed.

3.Position yourself so that the open-underside of the wheel is facing away from you.

4.Once a cut is begun and a notch is established in the workpiece, do not change the angle of the cut. Changing the angle will cause the wheel to bend and may cause wheel breakage. Edge grinding wheels are not designed to withstand side pressures caused by bending.
