[0002] Deep hole boring machine, also known as deep hole drilling and boring machine or horizontal deep hole boring machine, is a machine tool specialized for deep hole processing. Deep hole refers to a hole with a length to diameter ratio greater than 5. Deep hole processing technology is widely used in the production of cylinder barrels, drill rods, brackets, mechanical shafts and other workpieces in industries such as hydraulics, coal machinery, and industrial and mining machinery.

[0003] Among them, the boring cutter self-feeding deep hole boring machine is a special deep hole processing machine tool, which can effectively solve the problems of large power demand, small feed volume and high power consumption.

This method not only fails to separate the cutting chips and coolant in time, but also some cutting chips and coolant will be spilled during the discharge process to pollute the production environment, increasing the difficulty of subsequent cleaning and maintenance. The side storage box will also occupy the space outside the machine base, affecting the staff's observation of the boring condition of the workpiece. Utility Model Content
