Using Abrasive Discs Safely

November 5, 2020
Home > Blog > Using Abrasive Discs Safely

We here at ADS believe safety is key when working with abrasives. We therefore only supply OSA Certified Abrasive Dics. oSa is the symbol for the highest safety worldwide and an internationally protected trademark. All Bahco cutting, grinding and flap discs are oSa certified which means they are produced following strict criteria to secure high safety standards and provide cutting solution to rely on.

ALWAYS

  • Observe the safety recommendations of the machine and wheel manufacturer
  • Keep the working area well lit, clean, tidy and free from obstructions
  • Avoid slippery and uneven floors and do not work on ice or snow
  • Ensure other workers in the vicinity and passers-by are protected from sparks and debris
  • Exercise care when handling abrasive wheels – they can easily be damaged
  • Store wheels in dry and frost-free conditions avoiding wide variations in temperature and the risk of damage
  • Visually check the wheel for damage or defects and conduct a ring test before mounting
  • Check that the wheel is the correct specification for the application and that the markings are intact and legible
  • Use the correct tools when mounting or removing a wheel
  • Ensure mounting flanges are in matched pairs, clean, free from burrs and undistorted
  • Use blotters to prevent wheel slippage where required
  • Make sure that work rests and workpiece clamping devices are secure and correctly positioned
  • Ensure guards are in position and correctly adjusted so that they do not foul the wheel
  • Rotate the wheel manually to ensure that it runs true and freely before turning on the power
  • Wear suitable protective clothing
  • Run the wheel for at least 30 seconds at operating speed after mounting or re-mounting. Stand out of the line of the
  • wheel when turning on the machine
  • Dress bench grinding wheels regularly to keep the cutting surface in good condition
  • Allow the wheel to come to rest naturally after turning off the machine
  • Ensure the workpiece is properly supported or clamped so that it cannot move during grinding or cutting
  • Spin out residual coolant from the wheel before turning off the machine
  • Report wheel breakages, keeping hold of all of the debris for examination
  • Ensure machine spindle speed is checked periodically using a tachometer
  • Ensure that damaged or defective wheels and worn-out wheels are destroyed to prevent them from being used

NEVER

  • Permit untrained people to handle, store, mount or use abrasives
  • Mount or remove a wheel until the machine has been isolated from its power source
  • Mount a wheel that cannot be identified or one which does not bear the correct marking
  • Mount a wheel on a machine which does not display its spindle speed
  • Mount a wheel that has been dropped, damaged or incorrectly stored
  • Apply force to fit the wheel on the mounting device or alter the bore size or allow the wheel to overheat
  • Tighten flanges with excessive force or use a hammer or extension 
  • Use damaged, distorted or dirty flanges and fastening screws
  • Use a machine which is not in good condition or one with a damaged guard
  • Turn on the machine until the wheel guard has been refitted, secured and adjusted correctly
  • Stand in the line of the grinding wheel when starting the motor after fitting or re-fitting a wheel
  • Start the wheel in contact with the workpiece or any other object
  • Mount a wheel on a machine running at a speed higher than the maximum operating speed marked on the wheel
  • Work from a ladder or in a position where you do not have full control of the machine
  • Impact the work onto the wheel or the wheel onto the work
  • Grind on the side of a wheel unless it is specially designed for this application
  • Apply side pressure by trying to cut curves or by grinding surfaces with cutting -off wheels
  • Allow the wheel to bounce or be trapped or pinched in the cut
  • Use type 27 depressed centre grinding wheels at a steep angle or try to cut with them
  • Dress the wheel with any device other than that recommended
  • Press against the wheel surface to stop it or put down a machine until the wheel has stopped running
  • Wear the wheel down to the mounting flanges
  • Allow the gap between the wheel work rest to exceed 3 mm 
  • Allow coolant to run on a stationary wheel or leave the wheel running on an unattended machine
