For balancing of a turbine disk (1) this is equipped with two blocks (5) which are placed in a circular track (4) in the disk and which can be moved in this track until it is balanced. The blocks can be locked in the track e.g. while the bosses (8) on the blocks grip into the jack (7) arranged at even distances in the circumference of the track. In order to move the blocks in the track there is a tool (12, 13, 14) built into the machine, the tool is equipped with a carrier head (14, 15) which can grip and firmly hold a block while the turbine plate turns around its axle until the blocks are correctly positioned on the plate.<IMAGE> |
