在世界上几乎所有的生产过程中,轧辊都被广泛使用。
轧辊是轧制机的主要部件,经常会加入一些金属元素(如铬、镍等)。
在加工过程中,为了保证使用寿命和获得辊的耐久性。
辊的材料包括:铸钢辊、铸铁辊、硬质合金辊、陶瓷辊等。

固态CBN用于转动铸铁轧辊。

轧辊的切削参数。

在轧制过程中,切削刃是为了在较长时间内保持锋利。
还需要保持刀片的韧性,使刀具不会因为转动较大的轧辊直径而失效。

轧辊材料硬度(Hs)切削条件
V (M/Min) f (Mm/Rev) d (Mm)
硬质合金hra81 -86 5~30 0.1~0.3 0.1~0.5
高速钢超过85度20~50度0.1~0.3度0.1~2.5度
高速钢70~85 50~80 0.1~0.4 0.1~3.0。
模具钢hrc55 -62 60~120 0.1~0.3 0.1~0.5
镍晶粒铁70~85 40~100 0.1~0.5 0.2~3.0
高铬铁70~85 40~100 0.1~0.5 0.2~3.0。
冷冻铁65~85 40~100 0.1~0.5 0.2~3.0
球铁40~70 ~120 0.1~0.5 ~ 0.3~3.0
钢基亚当特40~60 ~130 0.1~0.5 0.2~3.0
加工辊的刀具材料包括硬质合金刀片、陶瓷刀片和CBN刀片。
CBN刀片是加工黑色金属材料最坚硬的刀具材料,是重型切削辊的首选刀具。

更多的超硬公司PCBN刀片在加工灰铸铁、球墨铸铁、淬火钢、烧结金属等方面具有优异的性能、较高的断裂韧性和切削刃强度、良好的耐磨性和耐磨性。
