1. A machining method for machining a metallic member using lathing and scraping, comprising:
(1) providing a machine comprising a machine support, a worktable for rotating the metallic member, a moving device, a lathe feeding mechanism, and a scraping feeding mechanism; wherein the worktable is positioned on the machine support; the moving device is slidably assembled to the machine support to slide along a first direction and located above the worktable, the lathe feeding mechanism and the scraping feeding mechanism are slidably assembled to the moving device to slide along a second direction perpendicular to the first direction, the lathe feeding mechanism comprises at least one feeding assembly and a lathe tool, with the lathe tool connected to the at least one feeding assembly, the at least one feeding assembly is configured for driving the lathe tool to move reciprocally along a third direction substantially perpendicular to the first and second directions when processing the metallic member, the lathe feeding mechanism further comprises a sliding saddle slidably connected to the moving device to slide along the second direction, and a mounting seat assembled to the sliding saddle, the mounting seat comprises a frame including a first side wall and a second opposed side wall that cooperatively define a receiving space therebetween; wherein a through groove is defined in the second side wall; wherein the mounting seat further comprises a guiding portion mounted on the first side wall, and a sliding portion mounted on the second side wall; wherein the lathe feeding mechanism further comprises a substantially T-shaped tool holder including a main body and a sliding board, the lathe tool is mounted to the substantially T-shaped tool holder, the sliding board extends through the through groove and is slidably engaged for movement in the third direction with the guiding portion within the receiving space, and the main body comprises a holding portion that is slidably engaged for movement in the third direction with the sliding portion mounted on the second side wall, the scraping feeding mechanism comprises a scraping cutter and is configured for driving the scraping cutter to move along the third direction; (2) positioning a metallic member on the worktable, the metallic member comprising a top portion and a peripheral sidewall extending from a peripheral edge of the top portion, the peripheral sidewall comprising an end edge away from the top portion; (3) moving the lathe tool by the moving device to contact the top portion of the metallic member; (4) applying the worktable to rotate with the metallic member along a first axis-parallel to the third direction; (5) controlling the lathe tool to move backwards and forwards toward the metallic member to machine the top portion of the metallic member circumferentially; (6) moving the lathe tool by the moving device along a predetermined path relative to the worktable to machine curved surfaces of the top portion of the metallic member; (7) holding the metallic member to stop rotating, and moving the lathe tool away from the metallic member; (8) driving the scraping cutter by the moving device to contact the peripheral sidewall of the metallic member; and (9) moving the scraping cutter along a predetermined path to scrape the peripheral sidewall of the metallic member, simultaneously controlling a feed of the scraping cutter relative to the metallic member. |
