一般的说成形铣刀用铲背方法制造比较容易,因为 铲背的形成铣刀,不需要特 殊的工卡具与磨齿装置。但 也有个别的成形铣刀,在铲齿时需借助于复杂的装置。如:大模数的齿轮指状铣刀 (如图1)大都具有下列特点: (一)成形面太宽,不可能用砂轮一次铲磨,必须使用靠模装置; (二)成形面斜 Generally speaking, it is relatively easy to make profiled milling cutters by using shovel-back method because the milling cutter for shoveling does not need special tools and grinding devices. However, there are also individual forming mills that require the aid of complicated devices for tooth scraping. Such as: Large modulus gear finger milling cutter (Figure 1) Mostly have the following characteristics: (a) the forming surface is too wide, it is impossible to use a grinding wheel shovel, you must use the die device;
