    Ceramic grinding wheel installation

    Ceramic grinding wheel is a new type of grinding wheel. The application of ceramic grinding wheel is first to check the safety quality of the grinding wheel. The method is to tap the side of the grinding wheel with a nylon hammer. The sound is crisp and there is no problem.

    The problem of positioning the ceramic grinding wheel and installing the grinding machine in a reasonable and suitable position is the primary problem before the operation. Grinding machines are forbidden to be installed in the vicinity of the equipment and operators or in the places where people often pass. Generally, the larger workshops should be equipped with special grinder rooms. If not, a protective baffle of not less than 1.8 m height should be installed on the front side of the grinder, and the baffle plate should be firm and effective.

    Protection problem, the protective cover itself is the most important protection device of the grinder. The function is to effectively cover the grinding wheel fragments when the grinding wheel is damaged due to work, so as to ensure the safety of personnel. The shape of the wheel guard is round and square, and the maximum opening angle is not allowed to exceed 90°; the material of the shield is steel with a tensile strength of not less than 415 N/mm2. When replacing a new grinding wheel, the installation of the protective cover should be firm and reliable, and the protective cover should not be dismantled or discarded.

    The matching problem refers to the problem of installation and matching of the chuck and the ceramic grinding wheel. According to the standard requirements, the diameter of the grinding wheel chuck should not be less than 1/3 of the diameter of the installed sanding disc, and the new grinding wheel should be replaced when the corresponding grinding wheel is worn to a diameter 10 mm larger than the diameter of the chuck.
