Abstract
Apparatus for cutting a flat surface on a metallic member may comprise: a frame assembly including a clamping device on which a metallic member may be placed for clamping the metallic member in a firmly fixed position; a broach frame mounted on the frame assembly for movement between a first position engageable by and against which the metallic member may be firmly clamped by the clamping device and a second position away from and not engageable by the metallic member when on the clamping device; a broach blade having cutting surfaces thereon carried by the broach frame for reciprocal movement, when the broach frame is in the first position, between a first terminal and a second terminal position for cutting a flat surface on the metallic member when clamped against the broach frame; and a power device mounted on the frame assembly and attached to the broach blade between the first and second terminal positions. Also disclosed is a method of production line hardness testing of metallic members utilizing the apparatus of the present invention.
