Abstract

The invention relates to a forming cutter for machining arc-shaped holes and a cutter machining method and belongs to the field of cutter machining. The purpose is to solve the problems that in the prior art, a forming cutter is complex to manufacture, higher in cost, large in bouncing in the machining process, low in machining precision and low in machining speed and working efficiency, and scraps are difficult to discharge in the machining process. The forming cutter comprises a cutter head part and a cutter body which is a cylinder, a center line through hole is machined in the center line of the cutter body, and the cutter head part comprises two arc-shaped cutting edges fixedly installed at the right end of the cutter body and arranged in a central symmetry mode.

Description

technical field [0001] The invention relates to a forming knife for machining arc-shaped holes and a tool processing method. Background technique [0002] The forming tool is a special tool for processing the forming surface of the rotating body. Its cutting edge is designed according to the contour of the workpiece. When it is processed with a forming knife, the forming surface can be cut out as long as it is formed by one cutting. However, the forming knife in the prior art is complicated to manufacture. , The cost is higher, the tool jumps greatly during processing, the cutting is difficult during processing, the processing accuracy is low, the processing speed is slow, and the work efficiency is low. Contents of the invention [0003] In order to solve the problems of complex manufacturing and higher cost of forming knives in the prior art, larger tool jump during processing, difficult cutting during processing, low processing accuracy, slow processing speed and low wo...
