TURBINE BLADE TIP FINISHING APPARATUS AND METHOD.

摘要

device and method for finishing the edges of improved turbine vanes of a similar.the method is particularly useful in the case of turbine blades which have been reparees by re welding.an abrasive (42) - first of all the surplus solder (30 ') with a back and forth motion and constant force.a detector (62) indicates when the abrasive is a distance above the surface of the predeterminee (c) outline of finishing required.then the removal of material for a pre-set period of time.during this period, the movement of the abrasive is pre-set in a converted motion along a path corresponding to the path of the guide edges of the finished surface by means of a cam (36).and a roller (50). the time of finishing is reduced and productivity increased.
