Mounted points General information Applications of mounted points 3 General use Surface grinding Edge grinding For general use on surfaces and edges, the emphasis is on the balance between abrasive performance and tool life. In surface grinding, the mounted points are subject to lower loads. The mounted point bond is therefore comparatively soft and has been designed to give high stock removal rates. In edge grinding, the mounted points must be dimensionally stable. The mounted point bond is therefore comparatively hard and designed for a long service life. Explanation of the code system according to EN 12413 D = Mounted point outer dia. T = Mounted point width Sd = Shank dia. L0 = Unsupported shank length L2 = Shank length L3 = Clamping length of shank (① collet) ① Sd D L0 T L3 L2 Safety notes All PFERD mounted points are approved for a maximum operating speed of 50 m/s. The maximum permitted rotational speeds for the various shank lengths and shank diameters are defined in DIN 69170 based on EN 12413. These must be adhered to in order to avoid buckling of the shank during use. Regardless of the shank length, the clamping length (L3) of the shank must be at least 10 mm. The maximum permitted rotational speed calculated according to EN 12413 is determined by the following factors: ■ Shape and dimensions of the mounted point ■ Diameter of the steel shank Sd ■ Unsupported shank length L0 Wear eye protection!
