★ 本机机架采用钢板焊接而成，经过振动时效消除内应力，防止机身变形。 ★伺服比例阀发出的流置和电子尺的讯号反馈结合：控制滑块(Y1、Y2)同步运行。 ★ 滑块下死点里霣精度为0.01m,折弯角度为0.5。 ★ 滑块快慢速转换点及上限位停靠点通过光栅尺反馈电脑调整。 ★ Full welded steel frame,stress relieved by vibration process ★ The parallrlism of the ram(Y1 ,Y2)achieved with the use of advanced proportional valve control anc the signal feedback by the linear scalse ★ Synchronization of Y1 and Y2 axis is within 0.01 mm,the bending angel is0.5 ★ Adjustable speed change over point and the TDC is depend on the feedback kf the position of the linear scales.
