High-strength swing head horizontal five-axis machining center and machining method

The invention discloses a high-strength swing head horizontal five-axis machining center and a machining method, and particularly relates to the technical field of five-axis machining.The high-strength swing head horizontal five-axis machining center comprises an operation table, side plates are slidably connected to the two sides of the operation table, the tops of the two side plates are fixedly connected with the same cross beam, and an auxiliary beam is slidably connected to the outer surface of the cross beam; an auxiliary block is arranged at the bottom of the auxiliary beam, and a fixing block is rotationally connected to the inner wall of the auxiliary block. The first threaded rod and the second threaded rod can respectively drive a limiting plate connected with a screw hole block to synchronously move towards each other or away from each other at the top of the operation table, so that the two limiting plates can be conveniently adjusted, and a workpiece placed at the top of the operation table can
