Abstract

The article notes that the development of industry poses the task of creating a general theory of the deep hole machining in the details. It is shown that drilling holes in details largely depends on the dynamic features of the mechanisms and the cutting process. A system of differential equations describing only the longitudinal and torsional oscillations of the cutting part of the tool is given. Using the example of the experiment on drilling holes with a diameter of 16 mm in austenitic, pearlitic steels, the problems associated with the construction of the cutting part of a gun drill, its wear, and the dynamics of the cutting process are shown. In a simplified setting, some features of the hydraulic system of the whole deep drilling machine are described, taking into account the supply of cutting fluid.
