如图所示的是我厂针对实际生产而设计的内孔镗槽刀。加工槽宽、槽外径、槽至孔端面,可一次调定,连续加工。1.原理与性能该内孔镗槽刀将旋转切削和径向进给合成一体。由主轴经柱销11和滚圈10带动筒顺时针旋转,实现旋转切削;由套3法兰面与工件孔端面贴合,主轴下压,斜楔1将刀12从方孔沿径向推出,实现径向进给。 As shown in the figure I designed for the actual production of the hole boring cutter. Processing groove width, groove diameter, groove to the hole end face, can be set once, continuous processing. 1. Principle and performance The bore boring cutter rotary cutting and radial feed into one. By the spindle through the pin 11 and the rolling ring 10 is driven clockwise rotation, to achieve rotary cutting; by the flange surface of the sleeve 3 and the workpiece hole end face fit, the spindle under pressure, the wedge 1 knife 12 radially from the square hole , To achieve radial feed.
