Increasing cutting tool efficiency when machining regulatory spindles made from ion nitrided nimonic 901 for steam turbine valves
Original language description
This article deals with issues during production of nimonic spindles used for controlling the volume of steam in the valves of steam turbines. With more extreme operating conditions in the power plant block with ultra-super-critical parameters of steam,the production of a conventional steel spindle is not suitable. This article describes machining technology for nickel alloy Nimonic 901. Ceramic or carbide cutting tools were used for the machining process. The text deals with progress of tool wear of the cutting edge. It describes the machining process to reduce tool wear during cutting. The second part of the report describes the process of ion nitriding nimonic spindles. The main aim was to get the best sliding properties on the surface of the spindle. The experiments confirmed the correctness of the solution. After nitriding several tests were performed, for example progress of microhardness of the nitrided layer and analysis of track wear after pin on disc test.
