Vertical Internal Broaching Machine L5520C

machine Dric：

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

These machines are driven by two hydrauliccylinders.They operate smoothly and give a stepless adjustment of cutting speed.There are multibroaching stations designed for the machine .When broaching workpieces,the broachs are convoyed in overall length,Sothey can improve efficiency and broaching accuracy.

These machines can be operated easily in automaticcycle,semi-automatic cycle ,step-by-step cycle or individually adjusted by inching drive.These machines equipped with the safety device against overload.
