The CNC press brake is primarily a machine tool that is utilized for bending a metal sheet or plate into a shape determined by its die set. CNC press brake plays a very important role in sheet metal manufacturing.

What should be considered when using CNC press brake?
Close the rear protective door of the CNC press brake. Turn on the power. Turn on the switch on the control panel of CNC press brake. Then, start the oil pump. The CNC press brake does not operate at this time. Release all emergency stop switches.
Adjust stroke. Pay attention to adjusting the stroke when using it. You must test it before bending. There must be a gap of plate thickness when its upper die descends to the bottom. Otherwise, it will cause damage to the CNC press brake. The adjustment of the stroke also has electric quick adjustment.
For the selection of bending notches for CNC press brake, a notch with a width of 8 times the thickness of the plate should generally be selected.
Backgauge adjustment generally has electric quick adjustment and manual fine adjustment, which is the same as the shearing machine.
Press down the blue "reset" button on the pedal and the "reset rearguard" button on the electric box, ensuring that the two blue reset indicator lights are off.
Turn the function forwarding switch to the "auto" position and press the motor start button after the controller self-test is over.
The CNC press brake finds the reference point and loads the corresponding bending program. Ensure that the mold installed in the CNC press brake is consistent with the programmed mold. Ensure that the sheet material is consistent with the programming page.
Remove the lower blade of CNC press brake and clean it piece by piece. Select one side to install tightly. Check the straightness of the blade in the horizontal and vertical directions.
Remove the upper blade of CNC press brake and clean it piece by piece. Then, the operation is same with that of the lower blade.
The upper blade is fixed. We adjust the blade gap by adjusting the lower blade.
The left and right screws of the lower blade increase the clearance. Loosen the four bolts on the table of the lower blade.
Manually turn the upper blade down to the proper position. The operator adjusts at the blanking area of the CNC press brake.
Use a feeler gauge to roughly adjust to 0.5mm from the unoccupied part of the upper and lower blades.
Manually turn the blade to the middle position and adjust it to 0.5mm.
Manually turn the blade up to the right position where the upper and lower blades are not disengaged. The middle position is roughly adjusted to 0.5mm.
Manually turn the upper blade to the proper position and start fine adjustment.
Before working, you must check the surrounding area of CNC press brake for any objects that may cause harm to it. Make sure the surroundings are clean, especially backgauge. Check the position of the oil mark in the oil tank. Check the hydraulic part for leaks.
The CNC press brake should be operated by professors. The operators must wear the corresponding labor protection supplies.
After turning on the power switch of the CNC press brake, do not start the oil pump immediately. Start the oil pump only after the computer screen displays normal.
After starting the CNC press brake, run it for 2 to 3 minutes without anything. Run the slide block at full stroke for 2 to 3 times. Check the motor and CNC press brake for noise. If the temperature is low, the oil tank and oil circuit must be preheated.
