Abstract
The invention relates to a method for manufacturing a carrying casing (12) provided with a collar (18) for supporting at least one cartridge of abradable material for a turbomachine, said carrying casing (12) comprising at least one bare annular casing (16) and one block of honeycomb material (20) that comprises an outer face (22) configured to be secured to an inner face (24) of said bare annular casing (16), said block being covered with a skin (26), characterized in that it comprises successively: —a step in which the outer face (22) of the block (20) is secured to the inner face (24) of the bare annular casing (16), —a step in which the circularity of San inner face (32) of the block (20) is monitored and in which, if necessary, the inner face (32) of the block (20) is machined to round, —a step in which, simultaneously, said skin (26) is produced and is secured to said block (20).
