Embodiment Construction
[0010] A method for processing high-precision stepped deep-hole parts, the following steps are adopted: a. Dividing the deep-hole parts into a part body I and a part body II according to the size of the aperture; b. Machining the inner hole of the part body I until the hole is formed, Leave the machining allowance for the outer circle, then process the inner hole and the outer circle of the part body II and leave the machining allowance respectively, and then assemble and weld with the part body I; c. After welding, press a plug into the outer end hole of the part body II, and then Drill the center hole on the outer end face of the plug, process the outer circle of the part body I and the part body II with the inner hole of the part body I and the center hole of the part body II to the finished product size; d, make the guide cylinder, the guide cylinder includes cylinder body 1, cylinder body 1 The outer wall is provided with several rectangular grooves, and the wooden support...
