CNC Tandem Press Brake-Bending for long workpieces
Benefits of Multiple Brake Configurations
While a drawback of using multiple brakes is part depth-each machine still has its own side housings that can interfere with bending wide parts-there are several advantages of using press brakes in tandem.
- Installation. Not only are tandem brakes cheaper and have a smaller footprint than a single enormous press brake, they are also much easier to install. Most facilities require significant alterations in order to transport in and even to operate a large-scale brake. Some companies have opted to have a reinforced foundation poured in an open area to accommodate a large press brake, then construct a new building around it! By contrast, no specialized rigging is needed when multiple regular-size brakes are purchased.
- Speed. A single large brake requires more time to perform a bend than smaller brakes in tandem. For a shop that is trying to maintain its productivity, faster is always better!
- Flexibility. Most multiple brake configurations are set up with multiple controls so that they can still be operated separately. A single CNC station is used for tandem operations, then separate controls can be engaged when needed so that the brakes can independently produce different smaller parts at the same time, doubling output.
- Accuracy. All CNC hydraulic press brakes are precision instruments, but the bigger the ram, the slightly less exact the control of it will be. Two or more smaller machines, with multiple hydraulic valves, scales and linear encoders combined along their length, will allow the CNC to have even more accurate control of the operation.
- Sharing. Most controls installed on multiple configuration machines permit the programming for part bending to be shared between them. Only one CNC would have to be programmed for a shorter part that all of the brakes could then produce.
- Down Time. When one of the brakes used in tandem goes down, the other can stay in operation making smaller parts. Production can continue on other projects, keeping the shop afloat while repairs are being made.
