Description
Technical Field
The invention relates to a conical grinding method for a front edge face of a rolling slotting tool, and belongs to the field of machining.
Background
The front edge face and the rear edge face of the rolling slotting cutter are combined to form a cutting edge, the cutting edge directly acts on a wheel blank when the gear is rolled and slotting is carried out, the cutting edge has a cutting function, bears cutting force and controls chips to be discharged out of a cutter face along the orientation of the chips. The rolling slotting cutter has the working characteristics that the rolling slotting cutter is meshed with a gear blank to generate motion, and impact load borne by cutting forms a sawtooth-shaped cutting edge which is easy to break. Therefore, increasing the strength of the cutting edge is an important measure for increasing the durability of the plunge cutter.
At present, a grinding method of a front edge surface of a rolling slotting tool mainly adopts a flat grinding wheel or a disc grinding wheel for grinding, and finishes grinding by interpolation composite feed motion of a machine tool. The diameter change of the grinding circle of the grinding wheel fed in the radial direction causes the change of cutting force by intermittent grinding, the cutter becomes vibrated, the surface of the front edge surface is rough, and the strength and the wear resistance of the front edge surface are further influenced. The change of the contact circle of the grinding wheel and the front edge surface of the rolling slotting tool forms a cutting edge of the rolling slotting tool in a step shape (zigzag shape) by the radial feeding of the grinding wheel. The intermittent cutting edge is most likely to break when it is operated, and is worn by vibration when it is cut at high speed. When a flat grinding wheel or a disc grinding wheel is used for grinding, due to the curvature change of each grinding point of the front edge surface of the inner cone of the slotting cutter, the grinding efficiency of the grinding wheel point grinding is low, the grinding wheel is easy to wear, the grinding quality of the front edge surface is low, and the quality of the surface of the processed gear tooth surface is poor. The micro-defect of unevenness of the front blade face formed by the interpolation composite feed affects the smoothness of chip discharge, increases cutting resistance and affects the tooth profile roughness of the tooth blank.
