PRECISION CNC MACHINING OF HPT AND LPT VANES FOR THE GAS TURBINE INDUSTRYHi-Tek manufactured these high and low pressure turbine vanes for use in gas turbine assemblies. Produced in sets they are used for aircraft and land based turbines and vary in size from 4" to 24" in length, 2" to 8" in width, and 3" to 6" in height. Manufacturing processes include radial grinding of the forward and aft ends, milling of the vane ends, as well as milling the hooks, scallops, and tapped holes. The cooling holes were drilled by a fast-hole EDM, sinker EDM, and Laser. TIG and laser welding was utilized on the assembly details and the electrodes were stamped in house for EDM hole drilling. The Grinding and Milled features were inspected with CNC CMM equipment and the cooling holes were CNC Optically inspected along with Airflow verification. These components were also grit blasted, tumble deburred, vapor degreased, and cleaned. At Hi-Tek Manufacturing we take quality seriously, we're ISO 9001:2008 - AS 9100 Rev C certified and NADCAP accredited for NDT & Non-Conventional Machining. Since 1980, Hi-Tek has manufactured well over 600, 000 of these parts. Hi-Tek has among the best quality ratings in the market, utilizing airflow testing, CNC optical inspection, radiographic inspection (X-Ray), fluorescent penetrant inspection (FPI), coordinate measuring machine (CMM), as well as hard gaging.
