Abstract

The invention belongs to the technical field of numerical control lathe machining, and discloses a tool for turning and drilling a center hole, a numerical control lathe and a machining technology. The tool comprises a tool bit, a tool bar and a center drill, a center drill mounting through hole is formed in the side face of the tool bar, and the center drill mounting through hole is used for mounting the center drill. The center drill is mounted in a variable-diameter sleeve, the variable-diameter sleeve is mounted in a through hole, the center drill is firmly mounted on the tool bar through pressing deformation of the variable-diameter sleeve, transformation mounting of the combined tool is achieved, and the transformed tool is applied to the numerical control machine tool. The tool for turning and drilling the center hole, the numerical control lathe and the machining technology have the beneficial effects that the problem about the precise and efficient requirements for rapid end face turning and center hole machining of shaft parts can be solved, the structure is simple, cost is low, and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of numerical control lathe machining, and relates to a cutting tool for turning and drilling a center hole, a numerical control lathe and a processing technology, in particular to a cutting tool for turning an end face of a numerical control lathe and drilling a center hole, and a numerical control lathe and a processing technology thereof . Background technique [0002] Turning is one of the most commonly used processing forms in product manufacturing. Turning tools, fixtures, and measuring tools are necessary tools for turning.
