Turbine Casing Refurbishment


Machine turbine steam seal faces



Equipment Utilised:

WB1500, GM4000 and MR2200


We have developed the WB1500 to machine the steam sealing faces of a turbine case whilst they are bolted together. It is able to machine both HP and LP stages in one setting and also machine welded stainless steel seats where complete refurbishment of the sealing face was a client requirement.

With our gantry mill (GM4000) and milling rail system (MR2200) we were able to machine the casing split lines back to the original specifications of within 0.05mm (0,002”) of flatness over the whole split line. The machines were aligned using laser technology and then the welded areas were machined back to the original faces.
