portable electro hydraulic punches

[exmoor dave]

Got a project coming up that will require A LOT of 8mm holes in 3mm plate. And to be honest would like a new toy!!
Been looking at portable punches. There appear to be two types;

One has a separate electro hydraulic power pack to a punch.

Other type is a all in one unit. Kind of looks like a hammer drill but with a mini punch unit on the end.

Mostly need it for 8mm holes 3mm plate but ideally something capable of maybe upto 20mm in thicker plate.

Anyone got any experience of these toys? Prices?
Ease of use? Price of punches etc?

OR
A another way of making loads of 8mm holes quickly?

we got a tool in our workshop that makes holes in metal.
thats it a pillar drill or if to big for pillar drill a hand drill. works fine.

not seen a punch machine bet they will be expensive. let us know how you get on.

Same here, already got a pillar drill, mag drill, god knows how many corded &cordless drills. But the problem is that drilling is tedious if large number of holes are needed.
I'm talking 100 holes per item!!

Draw it once on CAD and have it laser profiled- bang on accuracy, no marking out errors etc etc

I'd go with that! Many people don't realise that strictly speaking, a punched hole creates stresses in the metal which should be removed by reaming the hole to a larger diameter!

hi
have you got the items all ready which need the holes ?

I recently had some base and top angles made for a water tank. 50 X 50 angle with 20 x 14 slots every 127mm If the tank was only 9.0m diameter, (can't remember) that would be 446 holes. It was cheaper for my local engineers to laser the slots and then send them to be rolled than have them punched and rolled. Laser is automated, so very little labour needed, and labour is expensive!

Nope not yet. All in my head til lambing and shearing is out the way.
Just like to have my projects well planned out.
Basically each unit needs:
4x 12' angle 2"x2" x 5mm thick. Each needing 22 x 8mm holes.
3 x same as above but with 3 x 8mm holes.
20x pieces of 3mm sheet in 8' X 50mm strips with 4x 8mm holes.

So basically lots of holes in lots of component parts to make one unit. Hopefully if my prototype works I'll be making a lot more.
