机床长导轨的加工,大多采用以刨代刮工艺,最后工序是在龙门刨床上用宽刀精刨,其加工精度取决于龙门刨床本身的工作精度。因此,刨床的精度必须相应提高。以下介绍我们用以提高刨床精度的几项措施。一、床身侧顶螺杆支承柱结构的改进龙门刨床工作精度取决于床身导轨的精度,而床身基础的结 Machine guide rail processing, mostly used to shaver scraping process, the last step is in the planer with a wide fine knife planing, the machining accuracy depends on the planer itself work accuracy. Therefore, the accuracy of planer must be increased accordingly. Here are some of the measures we used to improve the accuracy of planer. First, the improvement of the structure of the bed side of the screw support column The precision of the planer depends on the accuracy of the bed rail, and bed-based knot
