Applications and Advantages

     This vertical internal broaching machine is designed with single oil cylinder and stationary worktable. It can be used to broach the inner surface of holes with various shapes (e.g. round holes, internal splines and inner gears). The machine is suitable for large batch production with high production efficiency.

 

● stable workpiece and stepless speed regulation due to hydraulic drive.

● equipped with a safety device against over load

● Work modes: automatic cycle, segmented cycle and inching adjustment.

● PLC programmed control allows all operations to be completed on main button control station conveniently and reliably.

● with functions of automatic chip flushing, automatic tool adjusting and automatic workpiece pushing.

● low space requirement, ground-level installation of the machine without a pit or pedestal.

● designed to machine small and medium-sized workpieces required higher accuracy.
