High precision electro-hydraulic servo synchronization control system:
High precision scale:Adopting high-precision scale as the displacement sensor, installed on the C-type plate, used to detect the position of the cylinder, the feedback accuracy is as high as 0.001mm, which can assist better control of the bending angle.
ESVP Energy Saving System:Smaller volume, simple installation structure, energy and fuel saving, servo motor drive, lower noise, high efficiency. Equipped with Rexroth valve and Rexroth oil pump as standard, which is stable and reliable, and can be used for a longer time. The cleanliness of the oil is reduced from NS7 to NS9, and the failure rate of the product is lower. Elimination of proportional valve cut-off and pressure valve overflow, low heat balance temperature, hydraulic oil consumption is reduced by 60% compared with traditional machine tools.Adopting high-precision electro-hydraulic synchronization, the bending precision is higher, anti-offset load and more durable.
