Engine Assembly Systems (EAS) for GE Engines
Engine assembly aystems are used worldwide to align and assemble high-pressure compressors and turbines (HPCR and HPTR) for jet engine and land-based gas turbine applications.
These engine Assembly systems feature ultra-precision air-bearing rotary tables and rotary encoders that are mounted to natural granite bases for durability and stability, ensuring the highest accuracy and repeatability.
With our heavy-duty adjustable tilt and center worktables, operators can easily bring the engine part precisely in alignment to the air bearings’ rotational axis. The spherical seat design on the worktable maintains the part’s center point when leveling, saving time in setting up for measurement and assembly.
Each system comes with a swing-away gage stands or taller counterbalanced gage towers allowing easy access when loading parts or unloading finished assemblies. Each gage configuration is able to mount up to 8 electronic indicators plugged into the state-of-the-art USB controller making quick work of setup and measurement.
ABTech is a licensed supplier of GE Aviation’s Genspect systems including USB controllers and stack prediction software. The controller has inputs for up to 8 LVDT gage heads and the rotary encoder from the air bearing table as well as a USB interface for PCs. And engine assembly system from ABTech now comes complete with the air-bearing platform, controller, required lever and plunger-type probes, Genspect software preloaded in a Windows-based computer, a large color monitor in a heavy-duty mobile electronics cart. A turnkey solution for assembling jet engines and turbines.
