加工铝件时,往往由于积屑瘤的生成与脱落,恶化加工质量,降低刀具寿命。为此,日本三菱金属公司开发了如图1所示的BF—407型端面铣刀,能可靠地解决这些问题。刀具的刃倾角7°,轴向前角+15°,径向前角+12°。刀片自身采用25°的大后角(图2),这样的几何参数,可有效地抑制积屑瘤,避免工件加工面边缘产生毛刺。由图1可以看出,BF—407铣刀中的刀 Processing aluminum parts, often due to the formation and fall of BUE, deterioration of processing quality, reduce tool life. To this end, the Japanese Mitsubishi Metal Company developed the BF-407 type end mill shown in Figure 1, can reliably solve these problems. Tool angle of inclination of 7 °, the axial rake angle of +15 °, radial rake angle of +12 °. The blade itself uses a large rear angle of 25 ° (Figure 2). Such geometric parameters effectively suppress built-up edges and prevent burrs on the edge of the workpiece. Can be seen from Figure 1, BF-407 cutter knife
