Based on this structural setting, the waste slag and coolant generated on the forward-feeding multi-axis horizontal deep hole drilling machine are guided and drained to the designated position as a whole by means of inclined guidance and controlled drainage, so as to achieve the overall waste slag and cutting oil recovery and processing operation during the cutting process.

When processing large gun drills, the machine tool shakes greatly, the processing efficiency is low, and the stability of the movement of the processing platform is insufficient. Therefore, we need to propose a three-axis horizontal deep drilling. Utility Model Content
