The invention relates to a novel adjustable double-edged boring cutter, which structurally comprises a main boring-cutter body, a boring-cutter head, a cushion block, a compression nut, a fine-adjusting nut, a knife holder and a blade and is characterized in that the main boring-cutter body is provided with an indented slot, insections which are matched with the insections of the main boring-cutter body are arranged on the boring-cutter head, the compression nut radially penetrates through the main boring-cutter body and the boring-cutter head, the bottom surface of the boring-cutter head is provided with a circular-arc slot which is matched with the fine-adjusting nut, the main boring-cutter body is provided with the indented slot which is eccentrically matched with the insections arranged on the boring-cutter head, and a novel cooing hole is formed in the main boring-cutter body. Compared with an existing double-edged boring cutter, the boring cutter disclosed by the invention has a good compression effect, and the accurate adjustment of the boring cutter can be realized; and the novel adjustable double-edged boring cutter is provided with the novel cooing hole, and the cooling hole is not limited by a chip flute, so that accurate positioning and cooling can be realized.
Description
technical field [0001] The invention relates to the field of numerical control tool manufacturing, in particular to an adjustable double-edged boring tool. Background technique [0002] For a long time, in the field of mechanical processing, especially in the field of CNC tool manufacturing, the adjustable double-edged boring tool is currently the most widely used boring tool for roughing and semi-finishing, and the boring tool is usually required to have various processing versatility and rigidity. [0003] During the cutting process, the boring tool rotates at high speed, and more than 80% of the force comes from the radial direction. At present, the most widely used adjustable double-edged boring tool adopts the structure of end face pressing and inclined plane positioning. The pressing direction and cutting direction Vertical, this kind of pressing method cannot give full play to the strength and rigidity of the tool base, which limits the processing capacity of the bori...
