Content | 0336 Edition 7/2012 617.0-IFA:638.22 Guards on stationary grinding machines Problem Guards on grinding machines must protect per- sons and the area around the machine against flying debris from grinding tools. During many processing tasks, such as the grinding of tooth- ings, the complex workpiece geometry does not allow to use a guard. In such cases, the protective function must be provided by wide-area encapsu- lation of the machining area or of the machine as a whole. This raises the question of the required wall thick- ness for such encapsulations in order for them to offer the same protection as conventional grinding tool guards . The values found in wall thickness tables such as those in the EN 13218 standard cannot be applied to such encapsulations. The usual design of the protective equipment and the resulting strain are not comparable with those of the relatively rigid guards closely enveloping the grinding tool. Activities Based upon burst tests performed on standard grinding wheels, practical criteria were to be developed for the design of guards on stationary grinding machinery which must be operated with- out grinding tool guards. The impact resistance of steel sheet DC01 and polycarbonate was tested. These are typical mate- rials from which guards are manufactured. Burst test bench with grinding wheel fitted The studies were conducted together with the German Social Accident Insurance Institution for the woodworking and metalworking industries (BGHM). Results and Application The impact resistance of the materials increased with both increasing thickness of the test samples and increasing width and decreasing strength of the grinding wheels. Doubling of the width of the grinding wheel resulted in the impact resistance being approximately doubled. For the rating of guards on grinding machines, the maximum kinetic energy of the flying debris is not |
