CNC Grinding

We can perform precision machining operations for hot gas path cooling holes as well as grinding under one roof


Hi-Tek has many 5-Axis CBN Grinders for generating radial features on highly complex nickel / cobalt turbine components. 

5-Axis CBN Grinding

Hi-Tek has many 5-Axis CBN Grinders for generating radial features on highly complex nickel / cobalt turbine components. Parts as large as 36" x 36" x 36" can be processed on these grinders.  Hi-Tek's central coolant systems provide ultra-filtered, temperature controlled grinding oil at constant delivery pressure for ultimate process performance.  Segmented nozzles, shrouds, vanes, fairings, panels, preswirlers, etc., are routinely produced to meet the exacting standards of aviation and power generation turbine engine manufacturers.
