Precision CNC Machining Of Ring Segments & Shrouds for the Gas Turbine Industry

Ring Segment

The Ring Segments shown here are components of a gas turbine assembly, the manufacturing of which utilized a variety of precision machining equipment. The parts where machined on a multi-axis creep feed grinder , 5-axis CBN grinder, a horizontal mill, multi-axis fast-hole and sinker EDM, as well as a 5-axis YAG laser.

Hi-Tek Manufacturing designed and built all of the tooling and fixtures for the machining processes. This ability gives us greater control over the manufacturing process. Production time is typically 4-8 weeks after receipt of order and material.
