Description

technical field [0001] The invention relates to the technical field of special machine tools for mechanical processing, in particular to a long overhang single-arm boring machine. Background technique [0002] At present, the special cutting machine tools used for boring both end seams, inner cavity holes and two end faces of large motor bases mainly have the following structural forms, [0003] 1. Single bar boring machine [0004] The principle of machining action: the workpiece does not move, the boring head rotates and feeds longitudinally to complete the boring, the longitudinal feed of the boring head stops when the end face is processed, and the movable tool bar radially feeds the end face of the car; the disadvantages are as follows: (1) the boring Poor straightness, coaxiality, and roundness; (2) Easy to vibrate the tool, and cannot cut intermittently, that is, it cannot process the machine base with longitudinal ribs in the inner cavity, and the digital display ca...
