Abstract: 500,112. Grinding milling outters. REISHAUER - WERKZEUGE AKT.-GES. July 2, 1937, No. 18472. Convention date, Aug. 11, 1936. [Class 60] In apparatus for relieving a helically fluted screw-thread milling tool by rotating the tool in contact with a grinding disc, the grinding disc used is a multi-grooved disc extending over the entire width of the milling tool, the disc being of conical form if the axes of the disc and milling tool are parallel or being of cylindrical form if the said axes are inclined. The Figure shows a milling tool F with teeth Z uniformly spaced apart by flutes g. The teeth are relieved by a multi-grooved grinding disc S movable towards and away from the tool by means of a relieving cam (not shown). If the axes of the disc and tool are parallel as shown in the Figure, the disc has an angle of conicity 8 which is obtained from the formula tan #= #.l/°.k, where ° is the tooth pitch angle, # the angular displacement of each tooth, k the width of the tool and l the amount of relieving. If the disc is cylindrical then the axes of disc and tool must be inclined at an angle #, The disc is trued by a pressure roller P.
