One of our biggest concerns is when a press brake owner starts to play with his machine before it is installed. When JMT sells a brake we ask the new owner to do certain things before we arrive to install it: make sure it’s where they want it, make sure it has power to it but we will make the connection, make sure that oil is in it, and make sure that it is ready to be anchored and ready to be leveled. Beyond that, however, we ask them to leave it alone. If an owner or operator decides they want to start running it before we get there, all sorts of problems and damage can occur, and we’ve seen that quite a bit.
If you are using a CNC press brake control and run into problems that you can’t figure it out, try restarting your machine. Just like a computer that locks up and has to be shut down to clear out a problem, “rebooting” your press brake is sometimes necessary. Shut the machine’s power completely off (the whole press brake and not just the control), let it stay off for 30 seconds to drain power from all circuits, then restart your brake. It’s not the most common issue, but it is the easiest fix for a machine, so before you call a repair technician that’s one of the first things to check.
A basic trouble-shooting technique for a CNC Y1/Y2 press brake having problems running a new program is to try the machine with an old program. We’ve known operators who decide that there must be a problem with a brake when all of a sudden something isn’t working right with a new program, yet the day before it was running just fine with a different program. If this happens to you, before you call a service technician, go back to a program that you know works and see how it performs. If it is working fine, then in all likelihood you may have created an issue in your new program as you were making it. You need to go back and go through and double-check what you’ve done or delete it and start over. This is a very common issue, since we all make mistakes.
More and more press brakes are coming with touch screen controls now and the cleanliness of the screen can affect the control’s performance. We’ve found many operators who think they are having problems with their screen and recalibrate it when it’s simply dirty and cleaning it would have solved the problem. People have natural oil in their fingers and get dirty hands while loading a press brake and all of that can leave a film on their control. You can avoid problems by regularly cleaning your touch screen with a soft cloth like a microfiber cloth.
