1, Y1, Y2-axis slide stroke control shaft, used to control the bending angle. At both ends of the machine is equipped with two encoders (Y1-Y2), which is used to determine the exact position of the slider and the table; grating is connected with the table, so that the elastic deformation of the column does not affect the position of the slider. Displacement data slider immediate feedback to the CNC system, which can measure the output of the servo valve control signal. 2, X-axis is the axis back gauge control is used to control the bending flange dimensions. X-axis is made of imported servo motor drive ball screw motion by synchronizing sprocket. Two gauge claw in motion remains in sync. Smooth transmission, high precision, low noise. 3, the cnc bending machine can be directly input to achieve multiple continuous bending, simple operation easy. Imported ball screw, imported direct rail. Imports synchronous wheel, timing belt. Two inlets servo motor drive (Y-axis and X-axis), bending maximize improve accuracy and speed, high accuracy while significantly increasing the speed of bending, work more efficiently.
