Abstract
The invention relates to the machining field and provides a method for finish machining of an inner hole cavity of a bent tube. A processing device used by the method comprises a processing cutter and a working table. The working table is a horizontal type circular disc or a sector-shaped disc revolving around a central shaft. The method changes linear feeding motion of a cutter body or a workpiece in a traditional machine tool processing method into curve feeding motion of a bent tube processing part along the axis, and the axis of a processing face of the cutter body is always tangent with a central axis of the bent tube, so that the finish machining of the inner hole cavity of the bent tube is achieved. The method is suitable for various models of bent tubes, has the advantages of being wide in application range, convenient to operate, high in processing accuracy, low in cost and the like, and effectively solves the problem of the finish machining of the inner hole cavity of the bent tube.
