For the resonance test, let the wheel hang from a piece of string and tap lightly with a screwdriver handle or similar (no metal!). If the sound is not clear, but rather dull and hollow the wheel is likely to be damaged and should not be used. The grinding wheel should slide onto the arbor easily. Forcing it on the arbor, e.g. by striking with a hammer, may break the wheel and is not permissible for safety reasons. For the same reason the drilling out of too small an arbor bore is not permitted. After the new wheel is mounted it should be left running idle for at least 5 minutes. Screen off workplace to prevent damage in case the wheel breaks and stay out of the danger zone. Grinding Wheel Wear Grinding wheels will naturally wear down with use. This requires a regular resetting of the tool rest and adjusting protective plate to the gap size as shown in figure 4. When a certain minimum wheel diameter is reached the tool rest can not be set any closer and the wheel has to be replaced. Depending on the grinding wheel diameter the following minimum wheel diameters (d mi.n) apply: Dry grinding wheels: 150 0 175 0 d . mm 110 mm 130 mm Wet grinding wheels: The work piece supporting mechanism does not need to be readjusted in the case of wet grinding wheels. Make sure that the grinding wheel is replaced when the minimum diameter has been reached (at the latest!). 150 0 175 0 dmi„ 65 mm 65 mm Changing the dry grinding wheel If the dry grinding wheel is worn and must be replaced, or you would like to use another type of grinding wheel, the old grinding wheel must first be removed as shown _ in Figure 9. 1 Hexagon head screw 2 Hexagon nut (possibly with serrated lock washer) 3 Outer cover 4 Hexagon nut 5 Clamping flange 6 Grinding wheel 7 Rotary shaft Changing the wet grinding wheel Let the water drain out of the water holder. Undo the two hexagon screws on the water container -(black arrows). Pull down the water container. 11 Undo the hexagon nut (1) on the wet grinding wheel. Remove all parts from the rotary shaft. The rear clamping flange (5) remains on the rotary shaft. Clean the two clamping flanges and carry out a sound test (Fig.8) on the new grinding wheel. Reattach the new grinding wheel as described above, but in reverse order. 1 Hexagon nut (standard right hand thread) 2 Washer or split washer 3 Front clamping flange* 4 Wet grinding wheel 5 Rear clamping flange ’not required with all TN models. Specifications Cleaning A Caution! Always pull out the plug priorto cleaning! Every now and then clean the outside of the grinding machine with a damp cloth. Make sure to clean the inside of the grinding wheel casing. The grinding wheels must always be able to run smoothly within the casing. Cleaning the water container Remove the water container as often as possible and clean it from the inside using water and a brush (no metal brushes!).
