If your back gauge controller is part of an older machine, it has probably reached the end of its useful life. However, it is likely that your back gauge itself still works mechanically, and only the back gauge control needs replacement or upgrading. The back gauge system can vary significantly in size, affecting upgrading the back gauge controller. However, the upgrade process is much more cost-effective than replacing the back gauge if it still works mechanically. Replacing or retrofitting your back gauge control can be essential to increasing your press brake's output. And can make the retrofit process worth your time and money, instead of just attempting to work inefficiently with a machine that does not work correctly. However, you should replace or upgrade your back gauge if the mechanical system is no longer working. Though it may initially cost more, the overall cost benefits will be more significant than using a faulty back gauge.
