高低排旋转双工位胀管机 Rotary double position expander for high - low row coil
特点：
1. 高低排胀管不需要更换U托及胀杆，只需程序中设定参数就可自动调节。 High - low row expanding does not need to change U - receiver and expanding rods, automatic adjustment can be realized by setting program parameters.
2. U托板及胀杆安装板分别由伺服驱动。 U - receiver board and expanding rod installation board are controlled by separate servo motors.
