Vertical Internal Broaching Machine Model L5120B

machine Dric：

This machine is designed for broaching holes of various geometrical forms in mass and batch production with high efficiency.

This machine is driven by hydraulic power and equipped with a safety device against overload. The machine operate smoothly and give a stepless adjustment of cutting speed and it can be operated in four kinds of cycles such as automatic cycle, semi-automatic cycle and two step-by-step cycles. Main actions of the machine can be individually adjusted by jerking-motion. The machine is operated easily on the main button control station.
