When in search of a press brake, or brake press, you have to know what kind of press you're searching for. Press brakes come in all sizes and with many alternative choices. You should purchase a brake press that's hydraulic, mechanical, air clutch, air trip, and of course CNC or pc numerical controlled.
It's essential to first know your Capability, which is rated by tonnage. Then you'll want to know the legnth and distance between housings. The distance between housings is usually smaller than the capacity of the machine. If you wish to bend 10' and need to go past the gap, you will have a 12' brake.
As for the clutch, Hydraulic clutch is the safest, and most expensive. They are generally slower and have extra of a exact bend.
Air clutch machine work in the identical means except they use air to activeat the clutch. The difference is that you have to finish the rotation as soon as activated. This makes it extra harmful, but faster.
Air Journey, is a cheaper, generally aftermarket clutch system that may be added to a standard mechanical brake press.
Mechanical is essentially the most harmful of them all, you lose plenty of management. The clutch has to make a full rotation, and can't be stopped at any time during the process.
CNC press brakes are the newest in manufacturing. They'll have mutiple axis Backgauges, and you can program them to do completely different bends. That is probably the most costly and the perfect for manufacturing.
