    • A method of manufacturing a metal housing (14) includes providing a first passage (10) through the metal housing (14) and providing a second passage (12) through the metal housing (14), wherein the second passage (12) includes a region of intersection (20) which intersects the first passage (10) to define an opening (22, 122, 222) into the first passage (10). The method further includes subjecting the metal housing (14) to a heat treatment process to carburise an internal surface of the first and/or second passage (10, 12) and, subsequent to the carburization process, applying a hard stage electrochemical machining process to the carburised internal surface of the first and/or second passage (10, 12) to improve surface finish. Another aspect of the invention includes providing a second passage (12) through the metal housing (14) by means of a tool (46), such as an electrochemical machining electrode, having an active region without rotational symmetry about its axis (Y-Y). The active region is shaped to provide the region of intersection (20) with a generally conical taper (29, 31) to the opening (22; 122; 222).
    • 一种制造金属外壳(14)的方法包括:通过所述金属外壳(14)提供第一通道(10),并提供穿过所述金属外壳(14)的第二通道(12),其中所述第二通道(12)包括 交叉区域(20),其与第一通道(10)相交以限定到第一通道(10)中的开口(22,122,222)。 该方法还包括使金属壳体(14)进行热处理工艺以渗透第一和/或第二通道(10,12)的内表面,并且在渗碳过程之后,施加硬阶段电化学加工工艺 第一和/或第二通道(10,12)的渗碳内表面以改善表面光洁度。 本发明的另一方面包括通过诸如电化学加工电极的工具(46)提供通过金属壳体(14)的第二通道(12),其具有关于其轴线(Y-Y)的旋转对称性的有源区域。 有源区域被成形为向开口(22; 122; 222)提供具有大致锥形锥形(29,31)的交叉区域(20)。
