Embodiment 1
[0016] see figure 1 and figure 2 , the differential cutting combined hole processing tool for reinforced fiber composite materials includes a main cutting tool 6, a differential tool and a differential gear 2, the main cutting tool 6 is a twist drill, and the differential tool is an outer tool 5, such as figure 2 Shown; Differential 2 is a gear differential. The first output shaft 4 of the differential 2 and the second output shaft 3 are coaxial; the first output shaft of the differential 2 is connected to the main cutting tool 6, and the second output shaft of the differential 2 is connected to the outer tool 5, The outer cutter 5 is a tubular drawing cutter.
[0017] When in use, the input end of the differential gear 2 is installed on the machine tool spindle 1, see figure 1 . When the twist drill is drilling, the tubular pulling cutting tool rotates in the same direction or in the opposite direction, the rotation speed is higher or lower than the twist drill, and t...
Embodiment 2
[0019] see figure 1 and image 3 , the main cutting tool 6 is a trepanning drill, and the outer tool 5 is a tubular cutting tool.
[0020] While the trepanning drill is drilling holes, the tubular cutting tool rotates in the same direction or in the opposite direction, the rotation speed is higher or lower than that of the trepanning drill, the feed speed is synchronous or differential, and the tubular cutting tool completes the function of a certain cutting allowance At the same time, it can cut the fiber pulled out by the trepanning drill.
