Electro-hydraulic Type Press Brake CNC Controller

Structure

The design principle for both machines is different, it results in the different synchronous structures on both sides of the ram. NC press brake adopts torsion shaft to connect the both sides of the ram and force the ram to move up and down synchronously, in this way, NC press brake uses the compulsive synchronous way mechanically, so the ram parallelism cannot be check and adjust by itself. For the CNC Press brake, two linear encoders are installed on the machine both sides and the CNC controller can analyze the synchronous condition on both sides of the ram by the feedback from both linear encoders. If there is some error, the controller will make the adjustment by the proportional valve to keep the synchronization of the ram. CNC controller, hydraulic system and the linear encodes consist of the closed loop control system
