Primary Functions
The F-120-2 is a specific model of a pneumatic counterbalance or cushioning cylinder. Its primary functions in a mechanical punch press are:
- Counterbalance: To offset the weight of the press slide and upper die, making the press safer and easier to adjust.
- Shock Absorption: To cushion the impact at the bottom of the stroke, reducing noise and vibration.
- Assist in Reversal: To help push the slide back up on the up-stroke.
