Gun-Drill Insertion in Drilling Deep Holes by Means of Multifunctional Machine Tools

  • S. V. Kirsanov
  • R. S. TsygankovEmail author


The drilling of deep holes by means of gun drills is investigated so as to establish the parameters of the guide hole and its production. The rate of change in the load on the tool is proportional to the active length of the primary cutting edge. Assessment of the smoothness of tool insertion on the basis of the rate of change in the load on the tool is proposed.
