Machining method for inner sleeve of motor shell

The machining method of the inner sleeve of the motor shell comprises the steps that S102, an inner hole, a flow channel and a supporting base of the inner sleeve are machined, the flow channel is located on the outer wall of the inner sleeve, and the bottom face of the supporting base and the end face A of the inner sleeve are coplanar; s104, a lathe tool is manufactured, wherein the overall appearance of the lathe tool is annular; s106, the lathe tool and the supporting base are detachably connected together, and the lathe tool is clamped through a lathe chuck; and S108, the inner sleeve is subjected to finish machining through the lathe, so that the inner diameter and the outer diameter of the inner sleeve meet the requirements. According to the machining method for the inner sleeve of the motor shell, the inner sleeve is connected together through the lathe tool, the inner sleeve is subjected to finish machining after the lathe tool is clamped by the lathe chuck, and the inner sleeve is not directly clamp
