阶梯铣刀如图1所示,在刀盘1上可以装8个刀头,每个刀头在轴线方向偏移1毫米(图2)。图2是阶梯铣刀盘刀头孔位置的展开图。刀头径向伸出量逐个相差3毫米,因此一次铣削深度可达25毫米。由于连续铣削,负荷均匀,所以切削过程平稳,从而消除了单刀铣削时的振动现象,提高了光洁度和质量。刀头几何形状如图3所示,刀片材料为 T_(15)K_6,刀杆材料为中碳钢。刀具的使用范围:这种刀具可以用来铣削较大的圆孔以及较大的圆弧、曲面等,图4是用阶梯铣 Stepper Cutter As shown in Figure 1, cutterhead 1 can accommodate eight cutters, each offset by 1 mm in the axial direction (Figure 2). Figure 2 is a step milling cutter head hole location of the expansion. The radial extension of the cutter head varies by 3 mm one by one, so that the maximum milling depth can reach 25 mm. Due to continuous milling, uniform load, so the cutting process is stable, eliminating the single-pole milling vibration, improve the finish and quality. Tool geometry shown in Figure 3, the blade material is T_ (15) K_6, Arbor material is medium carbon steel. Tool range of use: This tool can be used to mill larger holes and larger arcs, surfaces, etc., Figure 4 is a step-milling
