Abstract

The invention discloses a PCD forming milling cutter for machining an automobile inlay. The PCD forming milling cutter for machining the automobile inlay is characterized in that the PCD forming milling cutter comprises a cutter handle and a cutter body, the joint between the cutter handle and the cutter body is in smooth curve transition, and a first cutting part and a second cutting part are sequentially arranged between the front end of the cutter body and the cutter handle; the first cutting part and the second cutting part are respectively composed of two or more blades distributed along the circumference of the cutter body, each blade in the first cutting part is composed of two continuous cutting edges, the blade of the second cutting part is provided with a cutting edge, the three cutting edges are respectively composed of an outer side cutting edge and an inner side buffering part, each blade is of a wedge-shaped structure with a wide outer side and a narrow inner side, and outer edge angles formed by the blades and the side faces of the blades are all provided with round chamfers. The PCD forming milling cutter for machining the automobile inlay can be used for machining automobile inlay parts, and the machined embedded parts are tightly embedded and are not prone to loosening.

Description

technical field [0001] The invention belongs to the field of mechanical processing cutters, in particular to a PCD composite cutter for processing automobile steering gears. Background technique [0002] Automobile steering gear parts are complex in structure and irregular in shape, requiring many parts to be processed and difficult. On the same processing surface, different processing parts may require multiple operations such as milling, drilling, reaming, reaming, and chamfering. If a single-function tool is used to process it, multiple operations are required. The precision of the finished workpiece is very low and cannot meet the assembly requirements due to the error in positioning due to multiple tool changes. During the process, milling, reaming, drilling and other processes are completed at the same time, which has many advantages such as high processing efficiency, high stability and high product precision. Contents of the invention [0003] Aiming at the situa...
