Influence of Coolant Properties and Chip Former Geometry on Tool Life in Deep Drilling

The aim of the article is to find a correlation between change in properties cooling agent and geometry chipformer, as both are reflected service life tool after deep drilling. reason for carrying out research requirement practice obtain economic efficiency production such demanding process When applying latest designs gun drills, it very important correctly set technological parameters maintain stability cutting process. One most correct removal heat from site, this will be ensured by pressure, temperature, percentage emulsion medium, well adjustment chip former. On basis, large number tests were carried out, consisting testing drilling cycles new, unfluted drills at constant feed rates spindle rotation frequencies. After testing, possible modify supplement existing methodology technology terms managing chip-forming geometry. aimed increasing re-grindings depending on changes concentration, pressure temperature agent, associated chipformer
