Difficulty Description: This component is composed of two parts, the inner sleeve and the outer sleeve, which are connected by threads of 7 mm length. The biggest difficulty is that when the thread is screwed into any position between 2mm and 7mm, the full jump of the outer jacket end face relative to the inner diameter of the inner jacket is 0.02mm. The inner diameter of the jacket is 55+0.005/-0.000, and the precise outer diameter of the jacket is 65+0.000/-0.005.
