Abstract

The invention relates to a processing technology of small-diameter, thin-walled, deep-hole, high-precision parts and its special grinding tool, which relates to a processing technology of thin-walled, deep-hole, high-precision parts and its special grinding tool. The invention solves the problems that it is difficult to meet the design requirements and processing difficulties of the cylinder body parts by conventional mechanical processing methods. The process steps of the present invention are as follows: turning the outer circle and end face of the blank, and adopting a stepwise progressive drilling method to drill through the first inner hole and the second inner hole layer by layer; The head rotates, and the parts make a low-speed rotary motion relative to the grinding head, and the grinding head grinds the parts to complete the processing of the parts. The end of the extended handle of the grinding tool adopts a Morse taper structure, and the grinding head is fixedly installed at the head end of the extended handle. The grinding head is made of white jade, and the extended handle is made of alloy tool steel. The processing technology of the invention is especially suitable for the manufacturing technology of small-diameter, thin-walled, deep-hole and high-precision parts in the field of mechanical processing.

Description

technical field

[0001] The invention relates to a processing technology of thin-walled deep-hole high-precision parts and a special grinding tool thereof, belonging to the technical field of mechanical processing technology. Background technique

[0002] There are many cylinder parts, especially the cylinder of the wing tension mechanism is one of the representative parts of the cylinder. The cylinder body is a small-diameter, thin-walled, deep-hole part, and the machining precision of the inner hole is high (see attached figure 1 ), the cylinder body will encounter many problems during processing, and it is difficult to realize it by conventional mechanical processing methods, and it is difficult to meet the design requirements. The most prominent feature is that the tool bar is thin and long during turning, the hole wall is thin, the tool bar rigidity is poor, the strength is low, and it is easy to generate large vibration and tool drop phenomenon, and the taper error wil...
