This is a quick test of my 30 ton Anyang STP-S Hydraulic Press compared to my Anyang ST 25 kg Pneumatic Power Hammer.
In the video I'm forging a piece of EN19 (4140) steel which is 50mm diameter by 2" long into what will be a flatter for the power hammer.
In my view the 25 kg Power Hammer has more percussive force than the 30 ton Hydraulic Press has squishable force. It seems as though the hydraulic press gets to a certain surface area it can squish to and no more. Moving the work piece in and out of the die to reduce surface area helps...
I must apologise for the image quality - as the forge room was warming up I think the camera was starting to fog - the camera had been left in the room overnight and was 4 degrees centigrade.
