Introducing examples of machining components for automobile propeller shafts!
We would like to introduce a case study of stub shaft processing that we conducted. This is a component for automotive propeller shafts, with a size of L214. The maximum outer diameter of the disc part is φ85, and the outer diameter of the shaft part ranges from φ27 to φ62. After centering the hot-forged rough material, we performed rough machining of the outer diameter using a lathe, inner diameter machining of the cup part, and spline rolling processing, followed by grooving and finishing of the outer diameter. Heat treatment and serration cutting are then carried out to complete the process. 【Case Overview (Partial)】 ■Product Classification: Stub Shaft ■Delivery Industry: Automotive Industry ■Application: Propeller Shaft Components ■Material: SV45C *For more details, please refer to the PDF document or feel free to contact us.
