High Temperature Super Alloys HPT BLADES

PRECISION CNC MACHINING OF HPT BLADES FOR THE GAS TURBINE INDUSTRY
These high pressure turbine blades were manufactured for use in gas turbine assemblies. Hi-Tek Manufacturing is a world class supplier of hot gas path components for the gas turbine industry. Composed of a high temperature super alloy, the high pressure turbine blades are one of the primary components in the hot gas path segment of a turbine and one of Hi-Tek's highest volume products.
The HPT Blade machining processes utilize a wide range of manufacturing processes. The initial grinding of the root form was accomplished using our multi axis creep feed grinders and a 5-axis CBN grinder. The cooling holes were drilled using a multi-axis sinker EDM, a 6-axis fast-hole EDM, or a 5-axis YAG laser. The root form contours were inspected with CMM equipment and the cooling holes were CNC Optically inspected as well as Airflow tested. The components were also deburred, vapor degreased, cleaned, and marked.
The finished parts can vary in size from 2" to 24" in length and 2" to 8" in width, featuring a surface finish of 16 RMS. Used in commercial and military aircraft as well as land based turbines for power plants up to 250MW, we have manufactured over one million of these products since 1980.
