日本长冈齿轮制造厂最近研制成用立方氮化硼(CBN)磨粒制成双面的磨光带(磨粒大小为0.3～6μm),对经过淬硬的磨削齿轮进行磨光加工。一般淬硬的磨削齿轮表面粗糙度R_(max)为1.5～5μm(▽7～▽8),经过CBN磨光带磨光以后,可以将表面粗糙度下降到R_α=0.4μm以F(▽12a～▽14a)。 CBN磨光带磨光的方法见附图,1、2为一对需磨光的齿轮,一个为主动轮,由齿轮箱的输出轴传动; Japan’s Nagaoka gear factory recently developed with cubic boron nitride (CBN) abrasive particles made of double-sided polishing belt (grain size of 0.3 ~ 6μm), the hardened grinding gear grinding. Generally, the surface hardness of hardened grinding gears is 1.5 ~ 5μm (▽ 7 ~ ▽ 8). After the CBN polishing belt is polished, the surface roughness can be reduced to R_α = 0.4μm with F (▽ 12a ~ ▽ 14a). CBN polishing belt polishing method shown in the drawings, 1,2 for a pair of polished gear, a drive wheel, driven by the gearbox output shaft;
