Use for under counter and cabinet. I know there are fancy double miter saws out there that do this but they are usually $10k+. This returns the J-channel. Figure:269 : Many bending operations have been developed to produce offsets and form the sheet metal for a variety of different functions. Bottoming out the punch may be an option—though not for your 0.25-in.-thick 6061-T6, which, again, is notoriously difficult to form. Another (and usually better) strategy is to air-bend with a relieved die (see Figure 2). The 12 (in inches) indicates the depth of the channel. I am using 24" long sheet metal stock cut into 4" thick pieces. If you’re not careful, you can completely fracture the bend line.

I'll be bending the metal using a jig just like the one in this 'ible.I'm a big fan of Atomic Zombie's builds. An example callout for standard channel would be C12x20.7#. Bottoming the punch and die in this way and applying the extra tonnage, you may be able to reach your targeted angle plus the springback, albeit with dramatically increased forming tonnage. by Marketing | Dec 11, 2020 | Aluminium Extrusion Bending, News | 0 comments.

I have seen these type of machines roll complicated double U channels for window frames, bicycle rims, and channel leg in and leg out. To create these precipitates, the aluminum is heated using a solution treatment at high temperatures and at a prescribed time, then quenched for rapid cooling. At some point the die becomes too narrow, and the punch doesn’t have the clearance it needs to overbend. Standard channel and miscellaneous channel are specified in similar fashions. How to do it: Begin with the finished side up, bend 90 degrees at about 2 inches from the edge. These machines are not cheap, but they can do what you want, depending on the diameter- really tight diameters would be harder. T6 aluminum is precipitation-hardened, which is a form of artificial aging that causes particles within the metal to be spread evenly throughout the grain structure of the metal. also use the sweep to mark the bend lines.
