在拉削加工中,用机械反向法控制拉床工作台的往复运动,常常出现撞车、碰刀、打坏齿轮等事故。究其原因,在于电动机断开电源后仍作惯性转动,致使工作台不能迅速制动。如何才能使电动机一旦断电后迅速制动呢?根据我们反复试验的结果证明,应用“电容制动法”能达到 In the broaching process, the mechanical reverse method to control the reciprocating movement of the broaching table, often crash, touch the knife, broken gear and other accidents. The reason is that the motor is still inertia after turning off the power, resulting in the worktable can not be quickly braked. How to make the motor once the brake quickly after the power it off? According to our repeated test results show that the application of “capacitor braking method” can achieve
