Advantages of Pneumohydraulic Drive
- Initial state: Supports 360° installation at any angle.
- Fast approach stroke: Driven by the approach cylinder to bring the tool into contact with the workpiece.
- Power stroke: Driven by the rear intensifier to complete pressing or forming operations.
- Fast return stroke: Pneumatic retraction of the approach cylinder and spring-assisted reset of the intensifier.
