Horizontal Internal Broaching Machine Models L6120C

machine Dric：

These machines are designed for broaching holes of various geometrical forms in mass and batch production with high efficiency.

They 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 cycle, semi-automatic cycle and two step-by-step cycles. Main actions of the machines can be individually adjusted by jerking motion. The machines are operated easily on the main button control station.
