Tools for processing complex-interscapular CHANNELS blisks of gas turbine engines

摘要

The invention relates to aircraft engine field, particularly to a manufacturing technology blisks of gas turbine engines, preferably having a complex profile of the blade. The tool has a body with a mechanism for moving the jaws in a radial direction (1), inside of which the cams (2) are mounted tool holders (3) for the end portions of which are arranged cutting elements. To improve the accuracy, the processing performance and increase tool life aforementioned cutting elements constitute a group consisting of at least two alternating interchangeable plates (4, 5), and an outer end forming a cutting edge or end and an inner cutting edge. In this case the tool holder (3) is designed as a circular sector with the annular wall, and the sides have reinforcing ribs. The tool holder (3) comprises slots for a group of interchangeable plates (4, 5). Interchangeable plates (4, 5) mounted in the tool holder slot (3) and fixed with the screws (8). The width of the cutting part formed end, the outer and inner cutting edges tool less interblade channel width at the root section, and the width of the annular wall of the toolholder (3) narrower than the width of the cutting portion. Cutting elements in each tool holder (3) are not more than two outer and two inner cutting edges. 3 bp f ly-5-yl.
