low pressure turbine vanes

  • Material Used High Temperature Super Alloys
  • Volume 600,000 since 1980
  • Delivery Location FOB origin

PRECISION CNC MACHINING OF HPT AND LPT VANES FOR THE GAS TURBINE INDUSTRY Hi-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.

HPT BLADES

  • Material Used High Temperature Super Alloys
  • Volume Over 1 Million processed and shipped since 1980
  • Equipment Used to Manufacture Part 3, 4, or 5-Axis Creep Feed Grinder 5-Axis CBN Grinder 5-Axis Wire EDM 6-Axis Fast-Hole EDM 3, 4, or 5-Axis Sinker EDM 5-Axis YAG Laser Hi-Tek designed and built Tooling & Fixtures for all processes

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.

Custom Laser

  • Dimensional 92" x 72" x 36"

CUSTOM LASER PROCESSING SERVICES Hi-Tek installed their first 5-Axis YAG laser in 1982. In the 30+ years since many additional 5 & 6 Axis Lasers of many sizes have been added. In addition to YAG Lasers Hi-Tek has C02 as well as the latest Fiber Lasers. Parts as large as 92" x 72" x 36"are able to be processed on Hi-Tek's CNC Laser Centers. LASER CUTTING For over 30 Years Hi-Tek has been using lasers for cutting many materials including high temperature NickleCobalt. Material thicknesses range from less than .010" up to 38 inches thick are routinely cut. Cutting final part configurations from sheet stock as well as Laser trimming formed sheet metal parts to exacting customer requirements are common. Non-metallic parts are Laser cut as well. In addition, openings of all sizes and shapes are cut into work pieces. LASER WELDING Hi-Tek has been 5-Axis laser welding for three decades. Similar and dis-similar aerospace materials are routinely welded. Covers, baffles, impingement sheets and other hardware are frequently welded to gas turbine HPT Blades, Vanes, Shroudes, Seals and various other hardware. LASER DRILLING In 1982 Hi-Tek purchased their first 5-Axis Laser. In the quarter century since, tens of millions of holes have been produced by Multi-Axis Lasers at Hi-Tek. Many new Lasers have been procured during this time as Hi-Tek continually expanded both capabilities and capacity. Parts up to 36" x 48" x 80" can be processed on our equipment. LASER ABLATION In the past few years there has been need for the ability to produce round and shaped cooling holes in HPT hardware AFTER TBC coating. Hi-Tek's technical crew addressed this need and developed a Laser Ablation process that today is routinely utilized on production HPT Blades, Vanes, and various other HGP components.
