PLEASE - Help me with this SHOP PRESS &/or BRAKE business. I've heard of hydraulic & air over hydraulic? What's the diff in a press vs a brake?

Does a brake go in a press?

Is there a web site that can help me understand this?

Thanks!!!!!

Thanks everyone! I see that a press is ---well it's a PRESS - used for pressing!

Evidently, a "Brake" when it was first invented should have been called a "Bend".

So you can bend with a brake, and if you REALLY want to bend you can use a press to push the brake! You can also use dies to bend with just a press.

As usual you all have been most helpful! I get more useful info from this group!

I don't know definition... but this is what I call a press brake... hydraulic operated with an anvil and die for bends... this is a homemade version of what shop outfitters gets $400+ bucks for... will do 90 degrees or better on 3/8" 3 " wide and anything thinner 10" wide... hope the picture comes out

plans are available...
hope this helps

Hi Bob,

A press is used for pressing and a brake is used for braking.....LMAO I just had to throw in that SWAG... Hey it's brake humor... very little humor at that.

A press doesn't make a very good brake. Why? A typical press has a single "center" press point where as a brake has two press points, one at either end. If a single point press is used for breaking then your metal will not be broke square from end to end. One end will be over broke and the other end under broke or both ends will be under broke or over broke.

A brake has independant end adjustments to stop the under/over braking. A good hydraulic brake has number counters on the "each" end stops. End stops= a large bolt with a jam nut. A brake also has two press points, one at either end.

Lets say that 1000 is read on both stop dials at either end. What usually happens the center will be 90* and one end will be under broke. You raise the under broke end jam nut to 10 points under or 990 in this case, then the metal will bend 90* all the way across. Without the independant adjustment there's no way to bend a perfect 90* angle.

Thats why a single point press brake will not bend a perfect angle.

For an example of a manual brake, the vinyl siding guys use a very light duty brake to bend their trim pieces. I have a Pexto 4' that will do 16 gage steel- about the thickness of a quarter. It will do 12 gage-nearer 1/8" thick a few inches wide. For heavier materials in wide widths, power brakes are necessary. Some brakes rotate part of the brake to bend the metal- mine does. The press brake uses mechanical or hydraulic power to push forming dies in a straight line and the shape of the dies form the metal. Often there are press brake dies offered on eBay and looking at the pictures of them will offer a good idea of the way they function.

A break is a device used to form metal or steel into certain forms, such as right-angle bends and the like. I'm sure there are breaks that can be used in a press, but there are also breaks that are stand-alone units, and they can be quite large and powerful - enough to bend fairly thick material. I aquired an old sheet-metal break in high school when the Vo-Ag teacher was cleaning out the shop and throwing stuff away. It's not very large and probably wouldn't bend very thick material, but who can pass up a free tool? It looks to be fairly old, so maybe it has some value.

At the risk of once again exposing my ignorance, my understanding is that a brake can be used with a press to bend stuff. I see in Northern Tool that they have a brake intended to be used with a bottle-jack type shop press to bend fairly hefty metal.

There are also hand-operated bench-mounted brakes for lighter guage metal.

A hydraulic press uses either a manually pumped jack or a electrically powered pump to supply hydraulic pressure.

I would assume that an air-over-hydraulic uses air pressure to accomplish the same task, but I'm not positive about that.

A press brake is a hydraulic press that uses male and female dies to form shapes. A brake holds a section of the material in a vice like clamp and a moveable bar rotates to form a bend of desired degrees in the unclamped section. I think.
