Abstract
The invention provides a processing method of a slender axle. The method comprises the following steps: step 1, aligning workpiece to be processed; step 2, processing a second end of the workpiece to be processed; step 3, fashioning the second end of the workpiece to be processed; step 4, processing middle part of the workpiece to be processed; step 5, turning around the workpiece to be processed; step 6, processing a first end of the workpiece to be processed; step 7, fashioning the first end of the workpiece to be processed; and step 8, polishing the whole body. Through processing the two ends of the workpiece to be processed step by step, the slender axle, which better meets requirements of surface roughness, beating test, static balance test and dynamic balance test, can be preferablyproduced. Because beating test for the workpiece to be processed is implemented twice during processing period, breaking edge phenomenon of the workpiece to be processed is reduced due to vibration and rejection rate of processing the slender axle is also decreased.
