Problems solved by technology

However, the hardness of the quenched roll can usually reach 86HSD ~ 99HSD. For such a high hardness roll, it takes a long time to use grinding, and the consumption of the grinding wheel is also large, and the processing cost is high.

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.

Abstract

The invention discloses a processing method of high-hardness rolls, comprising the following steps: (1) the roll with the hardness of 86HSD to 99HSD is placed on a lathe, a CBN polycrystalline blade is used as a lathe tool for carrying out rough machining to the roll at the cutting speed of 50 to 90m/min, the feed amount is 0.7 to 1.2mm/r, and the cutting depth is 0.5 to 1.5mm; (2) the CBN polycrystalline blade is used as the lathe tool for carrying out semifinishing machining to the roll at the cutting speed of 100 to 180m/min, the feed amount is 0.35 to 0.5mm/r, and the cutting depth is 0.2 to 0.5mm; and (3) the CBN polycrystalline blade is used as the lathe tool for carrying out finishing machining to the roll at the cutting speed of 200 to 250m/min, the feed amount is 0.15 to 0.3mm/r, and the cutting depth is 0.1 to 0.5mm. The method has short processing time, high efficiency and low cost.

Description

technical field [0001] The invention relates to a method for processing a roll, in particular to a method for processing a high-hardness roll. Background technique [0002] At present, the processing of rolls is mainly grinding. However, the hardness of the quenched roll can usually reach 86HSD to 99HSD. For such a high hardness roll, the grinding process takes a long time, and the consumption of the grinding wheel is also large, and the processing cost is high. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above problems and provide a processing method of a high-hardness roll with short processing time and low cost. [0004] The technical scheme for realizing the purpose of the present invention is: a method for processing a high-hardness roll, comprising the following steps: 1. placing a roll with a hardness of 86HSD-99HSD on a lathe, using a CBN polycrystalline blade as a turning tool at 50-90m / min Rough machining the roll a...
