TROUBLESHOOTING & TUTORIAL

Today we will share the operation manual of E21 NC Controller for Press brake machine, It can help the operator to use the machien in a better and easy way. The operator shall read through this manual and know operation requirements before using this controller. E21 controller provides complete software control and the operator can pick it up as soon as possible.

This is a complete set of relief valves. The role of the relief valve is to control the amount of oil during the normal use of the bending machine, including its pressure, to control it. If this valve is stuck and the spool does not work properly in this valve, what happens to the bender? It cannot be raised, it cannot be lowered, and it cannot be pressurized, that is, the oil pump motor is rotating forward, but the slider of the bending machine has no movement. So if this happens, let ’s first look at the valve light. When you step on the footswitch, see if the valve light is on or not. If the valve light is already on, but the machine tool is not generating pressure, the slider is not up or down. The valve is likely stuck.

Sometimes when we use the hydraulic press brake with E21 controller, the machine ram can not come down even we start the machine and step the foot switch. Today we will share the solution with you how to fix this kind of problem. When we check the E21 inferface, we will see that Y is not equ

Multi-V is widely used on the hydraulic press brake machines, which features different bending channels for different sheet thickness. When the operator wants to bend plates of different thickness, it is necessary for them to use different V-openings of the Multi-V die. Here we will show you how to change the bending channels on HARSLE press brake machines.

After long use of hydraulic NC press brake machine, most users will encounter such problem: The bending angles will be different on one bending line. For example, if we want to get 90 degrees, but the left side is 89 degrees, the right side is 91 degrees. Today we will share the solution with you.

For some new customers who operated HARSLE hydraulic press brake for the first time, they will be a little confused about how to start hydraulic bending machine when they receive the press brake in their factory. Today we will share some tips about how to run the machine correctly with you.
