Basic knowledge about cutting wheel

1  handling and storage

1.1 handling wheel must be handled with care to prevent the collision shattered.

1.2 wheel should be stored to prevent moisture and deformation can not be placed directly on the ground, should be paperback stacked on pallets or wooden frames wooden pallet, stacked to a height of not more than one meters is appropriate. Sheet wheel can not be diagonal or upright.

1.3 grinding wheel when the storage time from the date of production for more than a year, should be re-rotation test to confirm qualified.

2  Installation and use

2.1 select the wheel, according to their mode of operation, cut the objects and conditions of a reasonable choice of wheels; particular attention to: Cutting the workpiece should be T41 or T42 wheel, polished workpiece T27 or T27a wheel should be used.

2.2 wheel must be visually inspected prior to installation and not allowed to use if it is damaged.

2.3 Installing the wheel flange to meet the technical requirements, and requires contact with the wheel flange disk clean and smooth, tighten the wheel elastic medium is too loose, too tight or grinding wheel with flange contact surface uneven easily lead to wheel damage ; only allows the use of special wrench reinforced by hand, prohibit the use of a longer wrench, or beat wrench, and strictly prohibited to beat the wheel to be installed to prevent man-made damage to the wheel.

2.4 wheel machine spindle should be consistent with the technical requirements, with the aperture of the wheel to match. If the shaft diameter is too small, round to install a different heart, cause the wheel beating even blasting.

2.5 using the grinding wheel, grinding wheel must be installed on the shield, the operator required to wear protective equipment and other personnel is prohibited on the wheel work surface to ensure safe use.

2.6 wheel installed, 1 to 2 minutes should be idling, and then formally.

2.7 wheel speed should not exceed the trademark provisions of the pace of work, when the use of pneumatic equipment, especially in multi-machine use the same gas source to control the air pressure, it is best for each device to install a separate pressure limiting valve to prevent pressure unstable, and cause the wheel is too large to exceed maximum operating speed of rupture wounding.

2.8 use of abrasive wheels slowly into the knife, too much force could easily lead to a wheel stuck and crashed wheel phenomenon. If there is a wheel stuck to immediately shutdown and wheel lift, so that the grinding wheel burned or broken card.

2.9 does not allow more than the workpiece stacked cutting, because the pieces overlap without card, when tightened, the wheel work likely to be card broken, resulting in a serious accident.

2.10 should not be cutting the face of the grinding wheel for grinding work. The thin slices cutting wheel cutting angle of 90  cymbals shape grinding wheel angle of 15  to 30 .
