MQL Technology Including the BTA Deep Hole Drilling Machining
The traditional cast-type method of BTA deep-hole drilling(such as BTA or DF) has cutting fluid consumption of the existence of large, high production costs, pollution of the environment and endangering the health of the operator and other problems. In this paper, the MQL technology (minimum lubrication technology) is applied to the method of BTA deep-hole machining (ie, near-dry deep-hole processing), we also analyzed the function and effect of MQL machining cutting fluid. Through the near-dry deep-hole drilling experiment, we find that a water-soluble cutting fluid has good atomization effect and the processing system also has fine effect of cooling and chip evacuation. We proposed mixed-use oil and the low-temperature cold spray methods to improve the tool lubrication and cooling effect for some great issues such as tool wear.
