Experimental Analysis of Cast Iron Drilling with Dry and MQL Conditions
This chapter presents two set of experimental studies on dry and minimum quantity lubrication (MQL) drilling with shallow and deep holes. The first study is focused on high-speed (high-throughput) shallow hole drilling of compacted graphite iron between dry and MQL conditions. The second example is focused on deep-hole drilling (without pecking cycle) of nodular irons under various MQL conditions. All tested are conducted with the state-of-the-art coated solid WC-Co drills. Detailed experimental methods and key results are presented.
