If your back gauge control 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 to be replaced or upgraded. The back gauge system can vary greatly in size, which can affect the process of upgrading the back gauge control, but the upgrade process is much more cost-effective than entirely replacing the back gauge if it still works mechanically. Replacing or retrofitting your back gauge control can be essential to increasing the output of your press brake 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 properly. 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 greater than continuing to use a faulty back gauge.
