Reply:I have experience with mechanical (vs hydraulic) machines in the form of rebar shears. I would imagine the basics are still the same -- once you trip it, the stored energy in the flywheel is going to follow through and there's no stopping it. So slow approaches to the work are out, and you'd better be sure you're ready when you trip the switch.I have no experience with mechanicals of this type, though. It should be A LOT cheaper than any hydraulics you find as a general guideline.Hopefully someone with experience specific to this machine type and brand will speak up.Watch your fingers!
Reply:They are rated in tons. Just guessing I would say that one is about a two ton press. Iv'e used them before many years ago. I think you would be surprised if it would punch anything thicker than about 1/8th inch. Mild steel. Mac
Reply:" They are rated in tons. Just guessing I would say that one is about a two ton press"I have a several punch presses, I am not familair with this model, but my hand Di Acro is 2 tons, All my flywheel presses are more, my " guess" is 4, maybe 5 tons and I could be wrong.As to how thick of material, how much and or how big, that might shear 1/2x1/2 stock and choke on 1 x1/2, don't know the press but my guess is 1/2 rebar it would handle.A Note to remember these tyes of presses are not very flexible they do specific tasks very well, and very fast, if you want to retool to a different operation they are expensive. A good rule of thumb on presses is $1 on the press and $10 on tooling, so a $1000 press needs 10K of tooling to get a decent number of options. Thats the bad, the good read my post on square holes with the right die my Bliss will do 60 per min, my old 1920's about 15-20, and my hand about 2-3 per min. |
