introduction：A gear drive in which the axis of one or more gears rotates around the fixed axis of another gear(See picture Planetary gearing)。Planet gear bothcTurn on its own axis﹐And then rotate with the planetary frame around the fixed axis。Sun wheela﹑Planetary frame and inner gearbAll can be rotated around a common fixed axis﹐And can be connected with other components to withstand external torque﹐They are the three basic parts of this gear train。If none of the three are fixed﹐To determine the motion of the mechanism, it is necessary to give the angular velocity of the two members﹐This type of transmission is called differential gear train﹔If fixed inside gearbSolar wheela﹐It is called planetary gear train。Usually these two kinds of gear train are called planetary gear drive。

introduction：Since the20century80Since the end of decade，There have been many documented examples of hard turning replacing grinding。Such as low cost per piece、Advantages such as process flexibility and environmental protection are often used to justify the use of hard turning。Hard turning continues to grow at an impressive double digit rate。In the majority“world-class”In manufacturing organization，Hard turning has been accepted and implemented in one form or another。 As an accepted processing technique，Progress in hard turning is expected to be consistent with all other processing processes。To stay competitive，Pressure is constantly being exerted on production to reduce the total cost per part。So high productivity processing is nowPCBNThe driving force of tool development。 This article looks at tool ideas such as plugging and polishing techniques and reveals opportunities for both ideas。pass
