| 摘要 | PURPOSE:To make it possible to cut and finish a material by one step in a short time by a method wherein the material is processed to have a finished plane surface on one side surface thereof in a condition in which the deformation of the top end of the material due to a component force of cutting generating at the time of finishing the above-mentioned one side surface of the material. CONSTITUTION:A broach holder 15 is provided with a pair of right and left cutting lanes 16 and 16' for guiding the top end 3(4) of a steering knuckle as the material to be cut. Next, roughly processed surface 23(24) and sacrificial processed surface 11(12) are formed on one side surface and the other side surface, respectively, of the base section of the steering knuckle by progressive broaches 17a-17d and 18a-18d in a condition in which the top end 3(4) of the steering knuckle is rightly positioned. Further, the broaches 18a-18d are brought into contact with the sacrificial processed surface 23(24) so as to prevent the top end of the steering knuckle from bending at the time of surface broach processing. Thus it is possible to cut and finish the steering knuckle as the material by one step in a short time. | ||||||
