[0002] like figure 1 and Figure 1a As shown, it is a semi-conical cutting tool. The semi-conical cutting tool is a cutting tool commonly used for cutting lanyards. The sharp edges of the inner and outer shapes transition smoothly. The edge of the cutting knife is not sharp, resulting in edge curling. Manual filing and repairing of the sharp edge R processing is easy to damage the edge of the knife. At the same time, the processing efficiency is still low, and the processing quality cannot be effectively controlled.

The invention discloses a machining tool and method of a semicircular conical surface cutting cutter. The machining process comprises the following steps of material preparation, turning, heat treatment, turning, grinding, turning, milling, milling, milling, clamping, grinding, cleaning and packaging; and in the machining process, a special tool is used for cooperating with an R milling cutter tool, a conical surface cutting edge grinding mandrel is used for milling an inner and outer circular cavity, an inner and outer circular cavity sharp edge, a cutter point and a sharp edge. According tothe machining tool and the method, a sharp cutting blade can be rapidly manufactured, the machining is simple and convenient, the manufacturing cost is low, and is suitable for manufacturing and machining of a hanging rope type cutting cutter, the process is simple and convenient, and the machining quality is reliable.
Description
technical field [0001] The invention relates to a processing tool and a processing method of a semi-conical cutting tool, belonging to the technical field of mechanical processing. Background technique [0002] like figure 1 and Figure 1a As shown, it is a semi-conical cutting tool. The semi-conical cutting tool is a cutting tool commonly used for cutting lanyards. The sharp edges of the inner and outer shapes transition smoothly. The edge of the cutting knife is not sharp, resulting in edge curling. Manual filing and sharp edge R processing is easy to damage the edge of the knife. At the same time, the processing efficiency is still low, and the processing quality cannot be effectively controlled. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing method for a semi-conical cutting knife, which has simple tooling preparation, low cost, high processing efficiency and guaranteed processing quality. ...
