Cylindrical gear machining process

The machining process of cylindrical gears should generally include the following: gear blank machining, tooth surface processing, heat treatment process and tooth surface finishing. In the process of compiling the process, various process schemes are often adopted due to the difference of gear structure, accuracy grade, production batch and production environment. To
The process of preparing gear processing can be roughly divided into the following stages:
1) The formation of gear blanks: forgings, bars or castings;
2) Rough machining: cut more margin;
3) Semi-finishing: turning, rolling, gear shaping;
4) Heat treatment: quenching and tempering, carburizing and quenching, tooth surface high frequency induction heating and quenching, etc.
5) Finishing: finishing reference, finishing tooth profile
