Re: [CAD_CAM_EDM_DRO] Air Cylinder Press

You could have a relief valve near the end of the travel to blow off the
pressure very fast. Then you could close it to retract or have a spring
retraction. Just a thought:)
Have a great day!

Once the parts separate, there is nothing to restrain the air cylinder from flying to its fully extended position - except maybe fingers and toes. The impact at the end of travel will not be good for things either.
