  • the inclination angle ⁇ 1 with respect to the virtual straight line L1 of the cutting edge 27 held at 35 and inclined to the upstream side in the rotation direction M with respect to the virtual straight line L1 is changed as shown in Table 1, and the end face 60a (end face 50a) is changed.
  • the cutting process was performed.
  • the diameter of the rotating body 11 was 180 mm, the number of cutting parts 21 was three, and the following conditions were set.
  • Clamping pressure of holding part 0.2MPa -Clamp height (corresponding to the thickness (height) of the laminate of sheets): 80 mm -Moving speed of the support part 31: 600 mm / min ⁇
  • Rotating speed of the rotating body 11 6000 rpm
  • Cutting position The cutting position was set so that the center of the rotating body portion 11 was positioned at the center of the laminated body 60 of the sheet 50.
  • -Arrangement of the laminated body 60 of the sheet 50 The arrangement of the laminated body 60 of the sheet 50 was set so that the separator side was positioned upward.
  • Example 2 In the same manner as in Example 1, the end face cutting of the laminate 60 of 200 sheets 50 was performed 5 times, and it was examined whether or not it was within a desired processing accuracy range. ⁇ 0.05 mm was adopted as the range of processing accuracy. Of the five times, the number of times (success times) within the range of the desired processing accuracy was examined. Specifically, in one end (200 sheets) end face processing, when all 200 sheets were within the range of the desired processing accuracy, it was considered successful. That is, if one of the 200 sheets is out of the range of the desired processing accuracy, it is determined as a failure. The results are shown in Table 2.
