Rotating boring tool has lubricant led to cutting part through central channel via secondary channels discharging near tool cutting edge

摘要

The cutting tool for high speed machining with nano lubrication has the lubricant led to the tool cutting part end surface (12) through a central lubrication channel drilled along the rotational axis. A non- discharging end of the channel located near the end surface is connected to it by secondary channels (24) discharging near each end cutting edge (20). An Independent claim is included for a method of high speed machining using the tool.
