Features: EMH25 series are wide bolster press machine which can meet the requirements for large area sheet punching and high efficiency automatic multistage progressive die production. The machines feature high precision and efficiency, rigid frame structure, and minimize the machining deviation. With counterclockwise drive dual crank shaft, steel plates welded machine body, and hex rectangle guide ways, the load-deflection resistance and precision stability of the lathe are improved, which ensure efficient, stable and quality production.
