“This tool is working successfully! This has been an ongoing problem for us for years, I believe you have cracked the nut on this one!” –Aerospace Manufacturer
The Problem:
An aerospace manufacturer was having difficulty generating a consistent chamfer on a high pressure Inconel 718 turbine stator. The hole diameter was .0935 and it was a blind hole. The stator has a double flange configuration with one through hole in line with a second blind hole. The goal was to deburr the top and bottom of the first hole as well as the top of the second hole while maintaining a consistent chamfer size of .005-.015. The customer had been using a hand made deburring tool driven by a pencil grinder, which was very difficult. This operation took way too much time and proved to be very inconsistent and did not garner the results they were looking for.
The Solution:
E-Z Burr built a custom micro tool to deburr the 3 surfaces and hold a consistent .005 – .015 chamfer size. We had to ensure that the arbor pilot length didn’t damage the blind hole while still removing the burrs and generating a consistent chamfer in the desired size range. We accomplished this through design modifications to the arbor and blade.
The Results:
