How to Choose Sheet Metal Cutting and Bending

Thinking of building an enclosure for your latest project? Or maybe you’re working on a giant robot to terrorize the neighborhood? Chances are, sheet metal will play a part. Sheet metal comes in all manner of varieties and sizes. Here are some tips and tricks to help you get that shiny sheet into your desired shape with metal cuttinga nd bending procession.

Sheet metal Thickness you want to cutting and bending

One of the most important decisions when cuting&bending working with sheet metal is deciding what thickness you’ll need. Similar to wire, sheet metal thickness is measured in gauges, with a higher number indicating a thinner sheet. To measure the thickness, you can use a sheet metal gauge, which will show you thickness in both gauge number and thousandths of an inch. One important note, however, is that ferrous and non-ferrous sheet metals of the same gauge have different thicknesses, so you’ll need one gauge for ferrous metals, and one for non-ferrous.

Sheet Metal Bending

Bending sheet metal can be tricky, but with the quality pressbrakes with right tool it’s easy. Those who work with it regularly are likely to have a CNC controlled sheet metal bending brake in their workshop, but this tool can be a bit expensive for the hobbyist. Thankfully, there are a couple of wallet-friendly options that can help you get the job done.

Using the edge of your workbench, a length of wood, two clamps, and a mallet, you can fashion a rudimentary bending brake. Mark a bend line and place the sheet metal on the edge of your bench. Next place the wood parallel and slightly behind the bending line. Clamp the wood on top of the metal to the workbench. Finally, bend the sheet up by hand to the angle desired. If you want a sharp 90° bend, tap along the crease with a mallet.

As this is only for simple sheet metal bending procession, if you want fast&high precision for metal bending job, you need to consider NC&CNC pressbrakes, especially CNC pressbrakes for bending metal sheet, operator just need to enter the material details to CNC controller, the CNC controller will calculate the bending pressure and bending sequence automatically.

Here have some links you can see which kinds of hydraulic pressbrake suitable for your sheet metal bending jobs:

4 axis cnc press brake:

Hybrid pressbrakes:

With special bending tools, your CNC pressbrakes can bending any sheet shape you want.

Metal Sheet Cutting

Many different tools cut sheet metal, and each has its own strengths and weaknesses. Here are some of the more common tools, but they represent only a small number of options.
