Embodiment 1
[0007] The hardness of the roll used in this embodiment is 95HSD, the length of the roll body is 1450mm, and the diameter of the roll body is φ380mm. The lathe used is a C61125 lathe.
[0008] The processing method is as follows: ① The roll is placed on the lathe, and the CBN polycrystalline blade is used as a turning tool to rough process the roll at a cutting speed of 60 m / min, the feed rate is 1 mm / r, and the cutting depth is 1 mm; ② Then Using CBN polycrystalline inserts as turning tools, the rolls were semi-finished at a cutting speed of 120 m / min, the feed rate was 0.5 mm / r, and the cutting depth was 0.5 mm; ③ CBN polycrystalline inserts were used as turning tools to The roll was finished at a cutting speed of 210 m / min, with a feed of 0.3 mm / r and a depth of cut of 0.10 mm. The entire processing process can be completed in only 84 minutes, and the UT inspection of the roll surface and the eddy current inspection are all normal.
Embodiment 2~ Embodiment 5
[0010] The processing method of each embodiment is basically the same as that of embodiment 1, and the difference is shown in Table 1.
