Drilling openings of current conducting tips for wire welding
Analysis of defects appearing while treating deep openings of a small diameter in workpieces from dispersed and strengthened copper has been conducted. Machine design for drilling has been proposed. Influence of the main technological factors on productivity and resistance has been studied. The results of research process of small diameter openings treatment with spiral drill from quick-cutting steel are shown. Technological process of openings treatment using a lathe type machine with electro-dynamic vibrator has been worked out.
