Your ram is essential to the effectiveness of your press brake machine, and after some time, the ram system may need replacement. You should be looking at how accurate and efficient the ram system is and if both sides are consistently equal. If you are consistently having to rework and fix mistakes made by the ram system, it is likely time to replace the ram system, as those mistakes made by the system can cost a great deal of money. A ram system that is also not able to consistently repeat commands should also be replaced, as it is not efficient to have to fix the system each time to be able to repeat the commands. If the overall press brake system is working, aside from the ram system, it could be very effective and lucrative to replace the ram system, sooner rather than later.
