Abstract:

Article Preview

Near-dry deep hole processing technology is a kind of technology which dry cutting technology is applied to deep hole processing to save energy and decrease environmental pollution. In this paper, the structure and work principle of near-dry deep-hole drilling system were introduced and the cutting mechanism of near-dry deep-hole drilling was analyzed which include the mechanism of cutting fluid atomization and flow, the mechanism of atomized cutting fluid cool and lubricate, and the mechanism of separating chips into short pieces and discharge chips by air stream, etc. The mathematical mode of gas-liquid two-phase flow of atomized cutting fluid in drilling shaft and the cooling and lubrication mechanism of the capillary in cutting zone were introduced. It is found that near-dry deep hole processing has better cooling and lubrication effect through experiments.
