2.   Accuracy of the machine
Y1-Y2 axis:
Linear encoder for electronic ram depth—setting, equilibration, calibration
Y1, Y2-axis are the independent motion parameters of two cylinders controlled by CNC control system. Both ends of machine with a high-precision (resolution 0.005mm) linear guide from Germany, which used to determine the exact distance of the ram and the table, linear guide is connected with the table, eliminating the deformation of the slider position column impact. Ram running speed and location data through the two optical grating timely feedback to the CNC system, CNC system to calculate and output the servo valve control signal S1 ~ S2, control of two electro-hydraulic servo valve output flow, so that the two cylinder simultaneous .
Repetition accuracy       +/- 0.01 mm
Accuracy of positioning    +/- 0.02 mm

V axis: automatic bed crowning by CNC Controller.
Deflection of the bed and ram under bending load is an unavoidable fact of life with any brake, which tends to cause bed angles to be inconsistent from center to ends of part. The problem is further compounded by the fact that bending loads are constantly changing for job to job and even within the same part, due to variations in material strength, thickness, and bend angle, bend length and other factors. YSD’s adjustable bed crowning system will automatically calculate and adjust the amount of crown on the bed to the proper position from bend to bend if so needed.
The crowning table composes of many crowning wedges, they could move relatively, and one group of ideal curve could be achieved on the crowning table. Thus linearity of bending product could be guaranteed.
CNC crowning ensures the ram and table are parallel during the bending operation. Sheet thickness, length, die opening and tensile strength data are entered into the control. Force and related deflection of the table and ram are automatically determined, preloading is optimally obtained for each bend. With YSD HPS press brakes, you obtain an optimal bending process and excellent bending results form the first piece.
