How to Solve Problem of Large Bending Angle Error of CNC Press Brake

⒈Check whether the compensation deflection of the CNC bending machine compensation cylinder is large and cannot completely recover the zero position.

⒉Check if the CNC bending machine quick clamp is loose.

⒊Check whether the installation of the bow plate of the CNC bending machine is normal, and whether the screw hole is dead.

⒋Check if there is any change in the bottom dead point of the CNC bending machine every time.

⒌The variation of the CNC bending machine sheet itself (thickness, material, stress).

⒍Is there any looseness in the scale of the CNC bending machine?

⒎The positioning accuracy of the CNC bending machine is not accurate: whether the offset value of the proportional valve zero is suitable, the positioning can not reach the bottom dead center so that it cannot return.
