本夹具主要用于各种铲背成形铣刀磨内孔用。当铲背成形铣刀外径D大于100毫米时,刀刃径向振摆量一般应小于0.05毫米;当外径小于100毫米时,刀刃径向振摆量一般应不大于0.03毫米。否则,在加工过程中,会使成形铣刀加工的工件轮廓形状产生较大的误差。并且由于各刀齿铣削余量不匀,不仅产生振动,而且使个别负荷较大的刀齿迅速磨损,大大降低了成形铣刀的耐用度。但刀刃径向振摆量,分别由各齿背曲线与内孔的不同心度及各刃齿前刀面的径向偏差所决定(在刃磨前刀面时能保证各齿分度均匀的
The fixture is mainly used for a variety of back shovel forming cutter mill bore. When the shovel back forming cutter diameter D is greater than 100 mm, the blade radial swing should generally be less than 0.05 mm; when the outer diameter is less than 100 mm, the blade radial swing should generally not be greater than 0.03 mm. Otherwise, in the process of processing, will shape the shape of the workpiece milling cutter processing larger errors. And due to uneven milling allowance for each tooth, not only vibration, but also make individual load larger teeth rapidly worn, greatly reducing the durability of the forming cutter. However, the radial oscillation of the blade is determined by the different concentricity of each tooth-back curve and the inner hole and the radial deviation of the rake faces of the razor blades
