The specific embodiment
Below by embodiment the utility model is conducted further description; present embodiment only is used for the utility model is further detailed; but can not be interpreted as the restriction to the utility model protection domain, those skilled in the art can make the scope that some nonessential improvement and adjustment belong to the utility model protection according to above-mentioned content of the present utility model.
In conjunction with Fig. 1 to Fig. 5.
As shown in the figure, the railway wheel hole processes dedicated tool, comprises the knife bar 3 of blade 4 and fixed blade, and blade 4 planes are positive shapes from all directions, and the positive interval, eight limits of shape from all directions arranges four main cutting edges 1 and four wiper edges 2; Knife bar 3 has the blade fixed groove, and blade 4 is fixed in the groove by push type broach lever 5 and trip bolt 6, and blade 4 fixing rear main cutting edges 1 are 45 degree with knife bar 3 axis angle A.
