拉削加工时由于其工艺特点往往会出现交变的切削力,它必将导致机床振动和改变机床传动动态特性。尽管由此几乎不会损害加工质量,但会造成拉削刀具的显著磨损,从而导致高的刀具成本和加工成本。采用本文所述的一种特殊的传动结构方法可以降低切削负荷。 Broaching process because of its process characteristics often appear alternating cutting force, it will inevitably lead to machine vibration and dynamic characteristics of machine tools to change. Despite this, the quality of the process is almost not impaired, but significant wear of the broaching tool can result, resulting in high tool costs and processing costs. Using a special drive structure described in this paper can reduce the cutting load.
