用三面刃铣刀单刀铣削侧定心矩形花键轴,通常都采用先铣出键宽、再铣内径的方法。这样铣键侧时的切削面积大(见图a),尤其是铣削长花键轴时更为明显,往往铣出的健宽不一致。而且用圆弧刀头铣内径圆弧时,也由于切削面积大使刀头磨损快,致使铣削的花键内径不等。 笔者经过多年的实 Milling cutter with a three-sided edge milling center side of the rectangular spline shaft, usually first milling out the key width, and then milling the inner diameter. Such milling side when the cutting area (see Figure a), especially when milling long spline shaft is more obvious, often the mill out of the wide range of inconsistencies. And the use of circular arc milling cutter diameter arc, but also due to the cutting area Ambassador head wear fast, resulting in unequal milling spline diameter. The author after many years of real
