目前，国内外采用振动钻削来加工小直径深孔，但都存在着两类问题：一是振动钻削系统中，多数振动装置的振幅是不可调节的，或凋幅十分困难和麻烦；二是小直径深孔钻头的设计与制造，大部分是采用外排屑枪钻，很少采用内排屑深孔钻。由于小直径枪钻制造工艺上的困难，国内主要 At present, the vibration drilling at home and abroad to the processing of small diameter deep hole, but there are two types of problems: First, vibration drilling system, the vibration amplitude of most devices are not adjustable, or withering is very difficult and troublesome; Is the design and manufacture of small-diameter deep hole drill bits, most of which are made with external chip-removing gun drillings, and few use of internal chip-removal deep hole drilling. Due to the small diameter gun manufacturing process difficulties, the domestic main
