| 中文摘要: |
| 对普通钻床进行数控改造,使改造后的钻床既能实现数字控制,又能采用手动控制,在同一次安装中完成工件的钻、扩、铰多个工序,不仅确保加工精度,而且提高加工效率数倍;该技术还通过精确设定机械原点和开发螺距误差补偿功能,提高了定位精度和重复定位精度. |
| 英文摘要: |
| The paper discuss the design which making over the common driller with numeral controlling device so that it works with Numeral Controlling and hand - controlling, it can finishe three processes -drilling、enlarging and reaming out hole-in the same installation of work piece. After improving, not only work efficiency is increased many times, but also exactness positioning precision and repetition precision is increased remarkably because of the mechanical axis point has been enacted exactly and the reparation function of screw -pitch errors has been developed. |
