    Safety in the workplace is so important for any business. Whether the workforce spends their time in the office or at a job site, all employers want their employees to leave at the end of the work day without incident. Following work safety rules are crucial for all members of the business.

    For any business that uses Type 1 or Type 27 grinding wheels, there are steps worth taking to ensure employee safety. Here is Rex-Cut’s list of DO’s and DON’Ts to maintain workplace safety whenever using abrasive grinding wheels.

    DOs for grinding wheel safety

    1. DO inspect grinding wheel for any kind of damage including cracks.
    2. DO make sure the machine speed does not exceed the maximum operating speed marked on the wheel.
    3. DO use an ANSI B7.1 wheel guard. Position it so it protects the operator.
    4. DO confirm that the machine arbor properly fits the wheel hole or threads
