Abstract

The invention belongs to the field of machining, and discloses a long-depth annular hole machining method. The long-depth annular hole machining method comprises the following steps that 1, a long-depth annular hole tool is mounted in a tool magazine, and a part (2) is fixed on a workbench by adopting a clamp (1); 2, an annular hole (3) with a certain depth is machined in the part (2) and serves as a guide hole in the machining process of the long-depth annular hole tool; 3, rough machining is conducted through a hollow drill, and most allowance is removed; and 4, the annular hole (3) of the part (2) is machined through the long-depth annular hole tool, and the long-depth annular hole tool is fed and machined to the target size in the axis direction of the part (2) at the speed of 80-150 mm / min. A long-depth annular hole with the depth larger than 40 mm can be machined, the problems of low efficiency, poor quality and the like in the existing machining process are solved, the production efficiency is improved, and the production cost is saved.

Description

technical field [0001] The invention relates to a method for processing a long-depth annular hole, which belongs to the field of mechanical processing. Background technique [0002] At present, in mechanical processing, for annular holes with a depth greater than 20mm, gun drills or hollow drills are usually used. These two methods are time-consuming and inefficient for processing a single piece. The surface roughness of the parts is poor, and it is difficult to meet the requirements of the drawings. Caused bigger inconvenience and waste, improved manufacturing cost. It can be seen that the existing long-depth annular hole processing technology needs to be further improved and improved. The invention relates to a long-depth annular hole processing method, which combines a special long-depth annular hole tool to complete high-efficiency and high-quality processing of the long-depth annular hole. Contents of the invention [0003] Purpose of the present invention: In view ...
