If you are on the brink of steeping up your sheet metal fabrication abilities, you may have had your eyes on press brakes recently. You might currently know that a press brake is in principle a hydraulic sheet metal brake. You may perhaps have a vague thought of what is doable with a press brake – or you may perhaps be rather effectively informed about the boost in throughput and the extended flexibility you can count on from an upgrade to such a machine. You have certainly arrived at the starting point for your journey toward press brake- ownership. Prepared to dive deeper?

When you bought your manual sheet metal brake, there in all probability wasn’t a lot to think about.
You just want to figure out what size you needed, what good quality you wanted, and what you could afford. There seriously isn’t much additional to a manual brake.
With press brakes it is unique, since these are various beasts:

The addition of the hydraulic ram implies heavier materials can be bent
Electronic automation and ram control suggests substantially a lot more constant final results when you bend
Cnc manage on some machines implies the potential to carry out complex operations on a workpiece – with no possessing to handle it, or to manually transform adjustments to the machine.
But perhaps the single most critical, basic distinction to a manual brake, is the punch and die. These are the standard tooling elements of the press brake, and replace the functionality of the bed, clamping leaf and bending leaf of a manual brake. The critical thing to realize here, is the remarkable flexibility you get with a punch and die – just because the tools themselves never have a fixed width or shape like clamping leafs or bending leafs do. Alternatively, they are fully replaceable pieces of tooling that come in a lot of shapes and sizes. They deserve an post to themselves, but some of the factors they can do include various bends in one particular stroke, box and pan-style bending, etc – all with the identical machine.

Obviously then, the tooling is an crucial point to think about. But tooling can be added and replaced later, as you learn a lot more about the use of press brakes. There nevertheless is the selection of the machine itself. Here, multiple factors come into play:

Physical size of the machine, like the max length and depth of blank sheets it will take
Tonnage, understood as the quantity of stress per metre of functioning length it (the hydraulic ram) can physical exercise
Flexibility, for instance in how lots of sizes and types of tools it will accept, adjustability of ram speeds, of the back gage, and so forth.
Automation – mainly relevant for cnc press brakes. Which parts are automated, and to which degree. Is light poles press brake or six-axis kinds for example.
A general advice about prioritizing and picking between these several variables, would be to attempt and make an optimistic guess as to what your wants may well be just beyond the instant future. If you get a machine that is enough for your present wants, or what you assume those requires are, then possibilities are you might have underestimated the improvement of your business enterprise right after you have bought and implemented a press brake. Living with a bit of excess capacity for a whilst is less difficult than promptly outgrowing a machine, having to look at investing in a further comparable or bigger machine. Acquiring once is pricey sufficient, so make your purchase the suitable 1 – correct away. If in doubt, don’t be afraid to seek the advice of a metalworking small business related to your personal, and easy ask them what they would do in your shoes.
