Compressor Blade Airfoil Peen


This machine uses venturi style suction nozzles to shot peen turbine engine compressor blades with glass beads. Parts are fixtured on a door-mounted spindle table for easy loading and unloading. An optional second door is available for higher production capacities. The peening nozzles are manipulated by a servo controlled gun mover, which is programmed through the computer operator interface. Media flows are monitored for each nozzle, and air pressure is closed loop controlled for optimum process repeatability. All of the glass bead is screened in a vibratory screening separator to ensure that the media meets appropriate specifications.
