Description

technical field [0001] The invention relates to the technical field of spindle box drilling, in particular to a drilling system for a spindle box of a numerically controlled machine tool and a heat dissipation method thereof. Background technique [0002] The spindle box is the most important component of the machine tool. It is mainly used to arrange the transmission parts and additional devices of the machine tool. Therefore, when the spindle box is processed, it is usually necessary to open holes to ensure its use; [0003] However, after the current drilling device (or system) for the spindle drills the spindle box, the drill bit will generate a lot of heat due to continuous work, making the drill bit in a high-temperature working state for a long time, which will easily affect the service life of the drill bit ; [0004] Not only that, but after the headstock is drilled, a large amount of iron filings will be adsorbed on the drill bit, so that the drill bit will work u...
