背景技术
切削刀具是机械加工中重要的加工刀具，这些刀具大都由优良的硬质合金、金属陶瓷等材料制成，制作成本较高，而在切削加工中，刀具刀刃必会产生磨损现象，严重时甚至发生崩角、折断等严重事故，致使刀具不可继续使用。发生磨损的刀具都会经过重新研磨以便重复使用，有效降低加工成本。铣刀作为切削刀具的一种，在机械加工中得到了越来越多的应用，将磨损、崩角的铣刀进行重新研磨可有效降低机械加工的成本。
现有的铣刀是利用大型的铣刀研磨专用加工研磨机进行研磨，其主要是利用复杂的操作结构进行研磨，研磨机在进行铣刀研磨时，通常是需要选择研磨的刀具，再选择相对应的铣刀夹筒，将铣刀放置在高速转动的砂轮的相应位置，再对各种铣刀进行全方位的研磨。该大型的铣刀研磨机占地面积大，加工研磨的操作复杂，需要专业的工作人员进行操作，劳动成本高。
