盘式制动器及制动钳的拉削加工

Processing of disc brake and brake caliper by broaching machine

盘式制动器及制动钳的拉削是近期汽车工业发展的结果，引导我们进入该类零件的加工领域。对盘式制动器来讲相对较易加工，而制动钳由于本身的结构刚性差，易变形。因此，我们采用了各项措施：在拉削过程中，我们采用了不同的速度。粗、精拉削齿升量合理安排。

为了保证精度不受零件变形影响，在机床加工过程中，粗、精加工分段拉削。夹具增加辅支撑，减少零件变形。我们为此生产的平面外拉床，其主要参数为：

额定拉力：200KN

额定行程：1600mm-2500mm

Processing of disc brake and brake caliper by broaching machine Development of auto in recent period leads us into the field of disc brake and brake caliper broaching.Broaching disc brake is easy, but the bad rigidity and deformation of brake caliper makes us adopt measures:

We adopt different speed when broaching for the purpose of getting reasonable arrangement of rise teeth of rough broaching and finish broaching.

In order to guarantee the accuracy not affected by deformation of parts, finish broaching and rough broaching is individually. Additionally sup-port of jigs will reduce deformation.

The main specification of external surface broaching machine.

as follows:

Rated pulling capacity: 200kN

Nominal stroke:1600mm-2500mm
