提供している。 Figures 3 and 4 show the lug seat 27a of the transition piece.
and 28a, in which a punch 35 is positioned in the breech opening 30. First, a transition piece blank is formed by investment casting or other methods. The blank section of the transition piece is finished by machining, grinding, or other conventional methods. In a part of this manufacturing process, the front areas 31, 3 of the rear part 24
2 is partially removed by machining. In one embodiment of the invention, the transition piece blank includes a metal material in the front areas 31, 32 of the rear part (rear tail piece part) 24, and the front areas 31, 32 are machined.
The metal material removed from 32 supplies surface sheets (rag sheets) 27a, 28a at appropriate positions within a tolerance range. Furthermore, this manufacturing method provides that the volume of metal material in the front region 31, 32 is preferably not excessive and is a volume that can be machined by a single stroke of the punch.

にある。 As shown in FIG. 4, the punch 35 is provided with drilling teeth 36 which are machined and removed from the front areas 31, 32 as they move downwards (indicated by the arrows in FIG. 4). The punch 35 is provided with optimal teeth of selected size, length and angle, so that the machining of the front areas 31, 32 is uniform downwards in order to form the seat surfaces (lug seats) 27a and 28a. It is achieved with just one stroke. The punch 35 is preferably positioned to move perpendicular to the barrel axis or a line parallel thereto (see center line C/L in FIG. 4). With the punch 35 in the starting position during the machining stroke, the seat surfaces 27a and 28a are coplanar and each at an equal distance from one end of the barrel.
