众所周知,在车床上采用浮动镗刀来切削深孔效果较好.目前大多数工厂采用市场上可买到的矩形可调节浮动镗刀。但是,这种镗刀没有直径在30mm以下规格的。因为30mm以下的制造较困难。采用矩形镗刀时,其刀杆的制作精度要求较高,刀槽相对于刀杆轴线有对称度、平行度要求,槽底面也有垂直度要求。我们设计了一种圆形浮动镗刀,其结构如图1。这种镗刀可用于切削直径30mm以下的孔,镗刀制作简单,一般工厂均可自制,成本也不高。在镗削时,圆锥销带动刀体在刀杆的孔中浮动,与刀杆的槽
As we all know, in the lathe on the use of floating boring machine to cut deep hole better effect. At present, most of the factory using the market can be adjusted rectangular adjustable boring knife. However, this type of boring tool does not have a diameter of less than 30mm. Because the following 30mm more difficult to manufacture. The use of rectangular boring knife, the production of its precision requirements Arbor, Slot relative to the arbor axis symmetry, parallelism requirements, the bottom of the groove also has vertical requirements. We designed a circular floating boring knife, the structure shown in Figure 1. This boring tool can be used to cut holes with a diameter of less than 30mm. The boring tool is simple to make, and the general factory can be made by ourselves, and the cost is not high. During boring, the taper pin drives the cutter body to float in the hole of the cutter bar and the slot of the cutter bar
