When choosing a Grinding-wheel, there are a lot of things that you need to consider before you make your purchase, due to many different factors.
Here we take a look at the main factors behind your choice of a Grinding-wheel and the health and safety issues that need to be considered. Having read this buyer’s guide, you should not only have the right wheel for the job but also have taken the necessary precautions so that your use of the grinder is as safe as possible.
Health and Safety: A grinder can be one of the most dangerous machines in the workshop, which is mainly due to the wheels that are fitted to it. To ensure that you and your workplace are safe, we would recommend following certain guidelines.
Speed Rating: Before purchasing your wheel, check the running speed of your grinder as this should never be more than the wheel’s maximum speed. Running the wheel above its maximum rpm can be very dangerous and lead to it breaking or exploding.
Note: Some wheels are rated in meters per minute, whereas others are in revs per minute, so make sure calculations are done before fitting a new wheel.
Abrasive Wheels Course: In the work environment it is mandatory to have been on an abrasive wheels training course before working on this type of machine.
Wheel Integrity: All wheels should be examined after unpacking for any signs of damage that may have occurred during transit. If damage is seen or heard (using ‘ring’ test), the wheel must not be used and it should be returned back to the supplier.
Storage: Wheels should be stored in an area where they will not be susceptible to rough treatment or rooms where there are severe temperature fluctuations as this can damage the bond in the wheels.
Machine Set Up: Ensuring the machine is setup correctly at all times is paramount, making sure the guards are in place and tool rests adjusted to the correct clearance.
Personal Protective Equipment (PPE): Goggles should always be worn when grinding; when dressing, a suitable dust mask is also a must if dust extraction isn’t available.
Extraction / Ventilation: When dressing the wheel, suitable extraction should be used to remove the grinding debris.
