  • Method for machining a casing of an aircraft turboshaft engine and scraper tool for implementing said method
    Patent number: 10137515
    Abstract: A scraper tool for deburring an edge of an aircraft turboshaft engine casing is arranged to be mounted in a milling device. The scraper tool includes a body including, on a first end, a connection for the milling device and, on a second end, a deburring module including a turning lathe platelet including at least one cutting edge arranged so as to deburr the casing edge. The deburring module includes a guide adapted to contact the edge to be deburred so as to follow the profile of the edge to be deburred without modifying the orientation of the turning lathe platelet.

  • Method for machining a casing of an aircraft turboshaft engine and scraper tool for implementing said method
    Patent number: 9296052
    Abstract: A method for machining a casing of an aircraft turboshaft engine, the casing including an upstream edge and a downstream edge. The method includes: positioning the casing in a chassis; rotating the chassis at a rotational milling speed; milling a downstream edge and/or upstream edge of the casing by a milling device, so as to correct axial length of the casing; and deburring the casing edge so as to remove at least one burr formed in a vicinity of the edge as a result of the milling, the milling device including a scraper tool which turn-machines the burr as the casing is rotated.
