Safety in the Storage & Use of Cutting-Off & Grinding Wheels

All cutting-off and grinding wheels are breakable and it is imperative that users take the appropriate precautions. Abrasive wheels that are damaged, improperly mounted or improperly used are dangerous and can cause serious injuries to any person in the vicinity. This section contains a summary of the most important precautions. Further safety recommendations can be found in the country laws, decrees and technical standards in the FEPA safety code (Federation of European Producers of Abrasives, www.fepa-abrasives.org).

SELECTION OF THE WHEEL
Carefully read the label or the information on the wheel and make sure that the wheel is suitable for the application and has the correct dimensions. Check that the max. rpm of the machine spindle on which you will mount the wheel never exceeds the max.rpm printed on the wheel label. Follow any restriction of use and any specific instruction which may be indicated on the wheel or on attached documents.

INSPECTION & TEST BEFORE MOUNTING
Make sure that the instructions on the wheel and on the machine are compatible.

VISUAL INSPECTION
Carefully inspect the abrasive wheel: if it is damaged in any way do not use.

SAFETY EQUIPMENT
Before starting the cutting-off or grinding operation, the wheel guard must be in position and fixed securely. The wheel guard must be capable of catching broken wheel fragments effectively and capable of withstanding the impact caused by wheel breakage.

MOUNTING OF THE GRINDING WHEEL & USE OF THE MOUNTING DEVICES
Only mount the wheels on machines designed for the operation. Never use force when mounting.
Always use the mounting flanges supplied with the machine and ensure they are clean, never modify them in any way.

 

SAFETY ADVICE

DO’s

DO always handle and store wheels carefully. Cutting-off wheels should be stacked horizontally and flat, preferably on a steel base plate. Depressed centre wheels should be placed on top of each other or stored in the original packaging.

DO always visually inspect all wheels before mounting for possible damage in transit.

DO always use a safety guard and ensure that it is correctly positioned and securely fitted. It should cover at least one half of the wheel and protect the operator in the unlikely event of a wheel breakage.
NON-REINFORCED CUTTING-OFF WHEELS SHOULD ONLY BE USED ON FIXED MACHINES AND SHOULD BE CORRECTLY GUARDED.

DO always switch ‘OFF’ the power at supply source and/or remove the plug from the socket before changing the wheel.

DO always use the tools supplied by the machine manufacturer to change the wheel.

DO always ensure that the spindle speed of the machine does not exceed the operating speed marked on the wheel.

DO always use the correct wheel mounting flanges and ensure that they are undamaged, clean and free from burrs.

DO SEE EN 12413.

DO allow newly mounted wheels to run at operating speed, with the guard in place, for a reasonable time before cutting or grinding.

DO always wear EYE PROTECTION.

DO always wear appropriate safety clothing such as DUST MASK, GLOVES, EAR PROTECTION, OVERALLS AND SAFETY SHOES.

DO always have machine speeds checked regularly, especially after maintenance or repair. Machines fitted with speed control devices (Governors), must be properly maintained at all times.

DO check tension of driving belts, where fitted, on a regular basis. Belts must be kept tight to ensure full power transmission.

DO always secure the workpiece firmly while it is being cut or ground.

DO put portable machines in suitable cradles, when not being used, to avoid damage to the wheel.

DO always use a portable machine in a comfortable position, where the workpiece is well balanced and the machine is well supported.

DO grind at an angle above 30 degrees to the workpiece with a depressed centre grinding wheel.

DO keep the working area around cutting and grinding operations clear. It is very dangerous if an operator trips and falls with an operating machine in his hands.

 

SAFETY ADVICE

DON’Ts

DON’T handle wheels roughly.

DON’T use non-reinforced cutting-off wheels on portable machines.

DON’T store wheels in a damp atmosphere or in extreme temperatures.

DON’T mount a damaged wheel.

DON’T EVER exceed the maximum operating speed marked on the wheel.

DON’T force a wheel onto a machine spindle.

DON’T use mounting flanges which are incorrect, damaged, dirty or burred.

DON’T tighten the mounting nut or locking flange excessively. To do so can distort the flanges.

DON’T use blotters with depressed centre wheels less than or equal to 406mm (EN 12413).

DON’T use a machine which is not in good mechanical condition.

DON’T use a machine without a wheel guard.

DON’T use wheels without proper ventilation or dust protection equipment.

DON’T apply side pressure to cutting-off wheels. You should not bend the wheel.

DON’T stop the wheel by applying pressure to the periphery or face. Always switch the machine off and allow the wheel to stop revolving.

DON’T allow the wheel to be trapped or pinched in the cut.

DON’T apply excessive pressure onto the wheel so that the driving motor slows down.

DON’T grind on the side of cutting-off wheels or depressed centre wheels below 4.0mm thickness.

DON’T drop or lower a portable machine by the cable or airline onto the floor. A wheel can be easily cracked, if it is put down hard, by the weight of the machine. This is a common cause of wheel breakage.

DON’T grind with a depressed centre grinding wheel at an angle below 30 degrees to the workpiece.

DON’T use a machine in a position where you do not have full control of the machine and you are not well balanced.
