Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an electric pulse auxiliary processing device for processing slender shaft parts and a processing method thereof. Background technique [0002] With the development of civil and national defense industries, higher requirements are put forward for the manufacturing level of parts. Among them, the efficient and high-precision machining of slender shaft parts is an urgent problem to be solved in the current civil and national defense industries. Slender shaft parts are one of the most difficult parts in mechanical processing. Such parts have a large aspect ratio and have straightness requirements for the axis and contour lines. They are prone to bending and vibration during machining, and are difficult to process after machining. Obtain satisfactory surface roughness and geometric accuracy. [0003] The current ordinary horizontal lathe has low machining accuracy and ...
