上下模具之间的距离由光栅尺直接控制
Die Distance Directly Controlled by Linear Scale
• 安装在补正机架上的光栅尺（编码器）持续地以微米级的精度检测滑块的位置。
The linear scale(encoder)fitted to the independent bracket constantly monitors the ram position with micron class accuracy
• 滑块的定位精度与所需的负载变形不影响折弯精度。
Almost no effect from load-induced side frame defection,and accurate ram positioning is attained irrespective of requisite load.
