一、概述目前,螺旋锥齿轮的制造都是用刀盘进行铣削。为了保证刀盘重磨后齿形不变,其刀片一般均为铲背结构,制造复杂,成本较高。刀齿后面是铲磨成的,其光洁度难以提高,后角也受到限制,因此切削性能不好,加工质量较差。此外,刀齿的重磨备磨量在刀片的厚度方向,刀片随刃磨而强度降低,而且新刀片的厚度较大,使刀盘能装刀片的数目受到限制,影 First, an overview Currently, the manufacture of spiral bevel gear are used for milling cutterhead. In order to ensure the cutter after grinding unchanged tooth shape, the blade are generally shovel back structure, manufacturing complex, higher cost. Behind the knife teeth shovel into grinding, the finish is difficult to improve, after the corner is also limited, so cutting performance is poor, the processing quality is poor. In addition, the wear and tear of the knife teeth grinding wear in the blade thickness direction, the blade with the sharpener and lower strength, and the greater the thickness of the new blade, the blade can be mounted blade number is limited,
