摘要： The present invention relates to a method for deburring a ceramic foundry core (10) obtained by injecting a ceramic paste, said paste including a binder having a predetermined glass transition temperature, into a mold and having at least one surface portion with a surplus of material forming a burr (B) to be eliminated. The method is characterized in that it includes the following stages: a) disposing and attaching the molded, unfired foundry core (10) onto a mounting (300); b) placing a milling tool (100), having an elongated shape with a helically cut edge, onto a tool holder; c) causing the tool to rotate around its axis and touching the milling tool to said surface portion to be deburred; and d) freezing (400) the surface portion to be deburred such that the foundry core is maintained at a temperature lower than said glass transition temperature during the deburring operation.

摘要： The invention relates to a method of manufacturing a cast ceramic core comprising at least one recess, particularly for partitions, for a turbomachine blade in particular, comprising the shaping in a mould of a mixture containing a ceramic particles filler and an organic binder, extraction of the core from the mould, removal of the binder and a heat treatment to consolidate the core. The method is characterized in that a core rough casting without the said recess is formed in the said mould and in that the said recess is machined once the rough casting has been extracted from the mould and before the heat treatment operation. In particular, the machining operation is performed mechanically by milling with the removal of chips. The invention also relates to a tool suited to implementing the method.

摘要： A method of manufacturing a cast core with at least one recess, corresponding to a partition of a turbomachine blade, includes the steps of shaping, in a mold, a mixture containing a ceramic particles filler and an organic binder; forming a core rough casting without the recess in the mold; extracting the core rough casting from the mold; machining the recess in the core rough casting thereby forming a machined core with the recess; removing the organic binder from the machined core; and heat treating the machined core to consolidate the machined core. The step of machining the recess is performed before the step of heat treating the machined core.

摘要： A method for adjusting a predetermined contour of a turbine blade root including a main salient edge defined by a determined interior angle. The method includes: chamfering the main edge of the contour to obtain two auxiliary salient edges, associated interior angles of which are respectively greater than the interior angle of the main edge; and blunting the auxiliary edges obtained to fine-tune the contour of the blade root.
