FIELD: machine engineering.
SUBSTANCE: blank and tool, consisting of a drilling head and a boring bar are installed on the machine. The blank is imparted with rotation, and the tool is supplied with a progressive feed motion, and the holes are machined at a given depth by individual sections. After processing of each such rotation section of the blank and feed-motion tool stops producing measurement axis for the disposal of the treated area openings and combine axle holes drilled blank, then perform the next section of the bore. The lengths of the sections are determined by the formula given.
EFFECT: accuracy of processing deep bores in the direction and non-straightness of the axis is increasing.
