Vertical Internal Broaching Machine Models L515A

machine Dric：

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

The machines are driven by hydraulic power with smooth transmission and their speed can be adjusted steplessly. A safety device against overload is provided in its hydraulic system and a broach hand-ling mechanism is equipped on the machines with tables being fixed. Being able to be operated in five kinds of motions as automatic cycle, semi-automatic cycle, step-by-step cycles （Ⅰ、Ⅱ）and adjustment, the machines can even meet the requirements of various kinds of broaching.
