为了解决焊接式内孔螺纹刀刃磨困难,使用寿命低和加工质量不稳定的问题,该厂工人师傅在改制成功硬质合金不重磨内孔镗刀经验的基础上,一鼓作气节新成功硬质合金不重磨内孔螺纹刀。经一段时间的使用,效果良好。一、刀具特点该刀具由标准正三边形刀片稍加修磨而成。刀片的夹紧,采用螺钉偏心式,以方便使用。刀片在切削力作用下,能保持可靠的定位,从而保证了加 In order to solve the problem of difficult to wear, low service life and unstable machining quality, the factory worker’s master, based on the successful experience of reshaping hard alloy non-rebuilt bore boring tools, Alloy does not rebuild the hole thread knife. After a period of use, the effect is good. First, the tool features the tool from the standard Triangular blade slightly grinding from. Blade clamping, using eccentric screw to facilitate the use. Blade in the cutting force, can maintain a reliable positioning, thus ensuring the Canadian
