Problems solved by technology

The surface roughness Ra of the slender shaft is required to be in the range of 0.1~0.8. Since the length of the slender shaft is larger than the diameter, the slender shaft is easy to vibrate during the process of finishing the surface of the slender shaft. Knives appear, resulting in high scrap rate
Therefore, the reject rate of processing slender shaft in the prior art is higher

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.

Description

technical field [0001] The invention relates to the field of machining, in particular to a machining method for a slender shaft. Background technique [0002] Currently, slender shafts with a length-to-diameter ratio greater than 25 are widely used in industrial production. The surface roughness Ra of the slender shaft is required to be in the range of 0.1~0.8. Since the length of the slender shaft is larger than the diameter, the slender shaft is easy to vibrate during the process of finishing the surface of the slender shaft. Knives appear, resulting in a higher reject rate. Therefore, the rejection rate of processing the elongated shaft in the prior art is relatively high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing method for slender shafts, which solves the defect of high reject rate in processing slender shafts in the prior art, and realizes reducing the reject rate of processing slender ...
