Optimization Design and Simulation of Negative-Pressure Removing-Chip Mechanism of Deep Hole

Abstract:

In the deep-hole drilling process, chips can not be easily removed, so the influence factors of the negative-pressure removing-chips were analyzed on the existing DF negative-pressure removing-chip mechanism by the hydraulic pressure theory and the injection angle κ and negative pressure gap S were analyzed with FLUENT software. The results show that negative pressure effect were best in 32°of κ and 0.4 mm of S and negative pressure effect are better in 28°of κ and 0.5mm of S , which lay good theoretical foundation for the optimization and characteristics of negative pressure mechanism in near-dry deep-hole drilling.
