Vertical External Broaching Machine Models L7116 (L720B)

machine Dric：

These machines are designed for broaching plane and shape in mass and batch production with high efficiency.

These machines are driven by hydraulic power and equipped with a safety device against overload. The machines operate smoothly and give a stepless adjustment of cutting speed and they can be operated in four kinds of working cycles such as automatic, semiautomatic and two step-by-step cycles. Main actions of the machines can be individually adjusted by jerking motion so as to meet the requirements of various purpose operation. The machines are operated easily on the main button control station.
