PROBLEM TO BE SOLVED: To provide a manufacturing method of a coil bobbin and a deburring device capable of efficiently removing burrs which are formed between flanges of the coil bobbin.SOLUTION: In the deburring device, a deburring section including a cutting tool, a deburring part 11c including an ultrasonic wave generator 17 and a brushing part are provided in a conveyance path of a coil bobbin 4. In the deburring part 11c, distal ends 171a and 171b of a horn 171 of the ultrasonic wave generator 17 is moved in between first flanges 421 and 422 and second flanges 431 and 432 of the coil bobbin 4 along a parting line P. The distal ends 171a and 171b of the horn 171 become axial parts having the size in a direction of an axial line L equal to an interval between the first flanges 421 and 422 and the second flanges 431 and 432 and during deburring, the coil bobbin 4 is rotated in a circumferential direction in a reciprocal manner.SELECTED DRAWING: Figure 5 |
