CNC Machining of a Titanium Crank Shaft for the Aerospace Industry
At KL Steven we specialize in the precision CNC machining of complex aerospace components, from a wide array of materials. This component utilized many of our machining capabilities, and required extreme precision. Working from the customer supplied specifications, this AMS 4928, 6AL4V titanium component required both CNC and manual milling, turning, and drilling. It included numerous ±.0005" tolerance holes, and true position tolerances of ±.001" of many features to a reference face. Deburring was applied using a Tampico wheel abrasive compound, and was electrochemically etched to apply the required markings.
A component of this complexity required a great deal of quality control, we provided comprehensive dimensional and visual inspections throughout the machining process.
In addition, parts also received fluorescent penetrant inspections (FPI). We manufactured a total of 12 of these items for this aerospace customer in 26 weeks.
