摘要
针对某民用飞机关键部件——中央盒段高精深孔制备的问题,使用线镗工艺替代了悬臂式镗孔工艺;选用高精度数显模块化微调单元、马鞍座千分表,实现快速且可靠的调节;应用杆式千分尺,解决线镗在线测量的问题。在普通落地式镗床上实现了IT5级精度的深孔加工。
Aimed at the problem in making the high-precision deep hole in the central box of a key component of a civil aircraft,the line boring technology instead of cantilever boring technology is used.With high-precision digital display adjustment unit and saddle dial indicator,the fast and reliable adjustment is realized.With the rod micrometer,the on-line measurement of line boring is achieved.Finally,IT 5 grade accuracy is achieved on the common boring machine.
